Q: If I remove the intake reeds will my boot collapse in on itself, and do I need one of those aluminum tubes that claim to prevent this and improve power?
A: The myth of collapsing intake boots propigated on certain YouTube channels is a complete sales fabrication and false claim, and our testing demonstrats mixed results with an intake airhorn. During multiple testing sessions on multiple bikes we found they can improve power up to 2-3 HP in the mid range, but then loose up to 7-8 on the top end. We neither sell nor recommend them, nor do we advise using them in your bike.
Q: Will I see any performance or power gains by removing the backfire screen on my OEM intake filter cage?
A: While it's a myth that it will, plenty of riders believe it does. Testing demonstrates that in fact it won't, however ‘placebo power’ is a real thing, so your results may vary.
Q: Is there anything specific I should do to my bike to extract the best possible performance?
A: Testing has proven that the best running bikes will have an open exhaust and the reeds removed.
Q: Do I need to worry about any basic settings like throttle position sensor or idle speed?
A: Not if those things are in factory specification. If the TPS sensor has not been adjusted from the base setting it shouldn't need adjustment or calibration. The idle speed on your bike should routinely be checked and verified as part of your basic maintenance program.
MORE INFO
Q: What fuels do we use for our tunes?
A: Fresh 91-93 10% ethanol unleaded
Q: Can I run this tune at high altitude or in a snow bike?
A: Absolutely. The Taco Tune is fully designed for bikes running from sea level to 19,024 feet - which is the highest passable road in the world in Umling La Pass, India. It's also completely ready to go full-send in snow bikes, trail cruisers, Baja 1000 rippers, BDR bikes, Sunday speedsters and anything else in between.
Q: How do I ship you my ECU?
A: For riders in the US, we’ll email you a free shipping call tag. Place your ecu in a plastic bag with the air removed and safely pack that into a small sturdy shipping box, do not use an envelope or bubble mailer. Print and tape the shipping call tag to the box and drop it off with the applicable shipping company. Label your ECU with your name, bike year and model. If you have special return shipping instructions include these in writing.
Q: Do you have an option for express flash / overnight shipping or core swap?
A: Yes, please contact us for more information. You might also consider the ‘tune at home’ program which eliminates the need to remove the ecu from the bike.

"So much fun, so much smooth power, so much better than stock. Night and day. I now have a bike I like to ride and no longer want to sell it, that's how disappointed I was with the stock power. Thanks to you guys, whatever you did it worked!"

"In one step (three really), I went from hating this 2025 500 EXCF to LOVING IT. However you guys did it, I don't really know or care but YOU DID IT. It wasn't that big of a deal or that expensive either. For $325 or whatever it was you did my reflash, For $259 I put on the PMB end cap, and for free I ripped out those reeds. So for what, $584 I now have a bike that Mike in a video says I'd be competitive in the Baja 1000 on. Sign me up! In my dreams right. But I can attest that this bike RIPS now and I'm completely in love with the tune, the bike, the sound, the everything. Plan on a ton of business there guys because all of my buddies have ridden this thing and all are saying they want the same set up. I better improve my ride skills because I still need to beat them. Thanks again Taco Moto."

"Legends man, the Taco guys just seem to be firing on all cylinders these days from what I can tell, and this flash tune proves yet again how you guys are leading the field in the sport. I'm finding this FE350 has the kind of power I need in the east coast woods racing I do and the casual riding too. She starts instantly and revs out like a banshee. Too much fun guys, thanks"

“24 GasGas EW500f, Pro Moto end cap, and removed reeds
Put in a couple hours Sunday in Western, PA. Bike started instantly every-time, never over heated, no codes, fan worked correctly and not one single flash out! Lugged up muddy rocky hills with ease and pulled liked a freight train in the straights. Glad I waited and 100% recommend.”

"I purchased the flash at home Powervision 3 for my 2022 KTM 500 EXC.
The tunning process was super easy and the diagnostics with the PV3 are very handy.
Ride review: The bike absolutely rips! It will power wheelie in all the gears but 6th. The power is very smooth with no dead spots. I highly reccomend getting you ecu flashed or flashing it yourself through taco moto!"

"Dude, your tune is a total game changer - night and day from the (name removed) tune I fought with before yours. The bike finally idles smooth without wild ups and downs, and the throttle response…instant and razor-sharp! The (name removed) tune had a weird lag with a sudden jolt that would snap my head back.
It also had my bike running hot; my header would glow red! Your tune is smooth, predictable, and seriously responsive… and no glowing red header! I'm 100% stoked - your tune has me smiling like a maniac lol.
Also… just a little venting… the (name removed) guy had me buying all kinds of shi* to try and fix the issues. Removed the thermostat for a straight shot thing they sold me, testing for an air leak, testing fuel pressure, etc. Finally I had to take it to a KTM dealer and paid for diagnostics. I was just throwing money away. Every time I told (name removed) it has to be the tune, I would just get push back. I wanted to reach out to you sooner, but I didn't have the money for a full race ecu, so when I saw that you guys had a reflash now I jumped on it right away. So super stoked about this tune!"

“Last weekend I took the bike out for the first time after being Taco tuned. Power delivery and flame out issue was so much better compared to stock. Bike was riding and running great for the first hour. I took a big hill in 3rd that was pretty rough, halfway up I lost all power above half throttle. It would just bog anywhere below half throttle.
I knew it was late on a Saturday but decided to reach out to Taco Moto anyways. Obviously got voicemail on a Saturday night, but to my surprise Sunday morning I got a text from Taco Moto asking how they could help.
They told me to double check the reeds to make sure they didn’t pop loose…. Sure enough, the reeds were just hanging out inside the air filter blocking off the flow. Once I removed them the bike ran flawless.
Super happy with the customer service from Taco as well as the bikes performance.”

"Wow guys - no words. This thing RIPS! Like insane how good it runs. I'm headed to Baja next week and you all got this to me fast and the way it rides is amazing. You were so right about the Pro Moto end cap and silent insert. Yes it's louder than stock, which is what I wanted, but it's not ridiculous at all. Great sound, great power, in fact everything you suggested that I bought is making me five stars happy. Great work everyone."

FREQUENTLY ASKED QUESTIONS
Q: What can I expect from a Taco Moto stock ecu reflash?
A: We’ve invested considerable time, effort and expense to offer a tune and configuration worthy of the Taco Moto name and ironclad guarantee. When you ride one of our tunes you can expect a crisp and clean throttle response, lower engine temps in before and after comparative ride tests, cleaner smoother power, increased power and performance equal to any race ECU on market. Our enduro map is light years ahead of the OEM enduro soft map and is like a ‘cheat mode’ for hill climbs, loose terrain and slippery conditions. All our tunes are put through the beat-down by Mike and the team of cracker-jack test riders in conditions ranging from the deserts of Baja to the high mountain passes of Colorado and everywhere in between. Mike is pretty obsessive about what he puts on the site and these maps are completely worthy of the Taco Moto name.

Q: I see there’s a few other ecu reflash options on the market, why should I go with the Taco Moto remap?
A: We've spent years building a global reputation of rider trust with our service, products and our Baja tested Baja proven philosophy. We also chose to work with Dynojet and their most experienced tuning engineer on our remap product, and those guys are the top name in the game for all things engine tuning and performance. In fact they're the only company to offer both a dyno and the integrated tuning software that tie them both together for the best accuracy and performance possible. The partnership of Taco Moto and Dynojet together with the team of industry experts and test riders we've assembled make this an entirely next level option in the ECU reflash game. We're so confident of that, if you don't agree, we'll give you your money back.

Q: I’m converting this bike to a Baja 1000 race machine and will be removing the street legal equipment, will I need to worry about the check engine light?
A: No, our tune won’t trip the CEL on any bikes.
Q: Can I run the stock exhaust and end cap with your tune?
A: The OEM muffler is a well-built unit well with strong materials and has great performance potential. However the stock enduro bike end-caps are up to 80% air flow obstructed and retain too much heat in the engine and choke back power. We like the stock muffler but not the end cap. A terrific and cost effective solution is swapping it out for the Pro Moto Billet unit. You might also want to look at the multiple slip-on and full system options available on our site as well. Whichever way you go, an open and free-flowing muffler is key to extracting the full potential of our tunes.
Q: What are the areas of the tune that your reflash improves?
A: Depending on the bike make, year and model - tuned areas may include: fuel and ignition calibrations, start up fueling, injector latency scaling, decel fuel cut off, ignition dwell timing, injection timing, feedback fuel, cranking fuel, after start enrichment, decel compensation, global barometric compensation, intake air temp compensation, throttle tip-in settings, sensor scaling, and a few others that are part of our secret sauce.
Q: My bike pops and snaps on decel, will a reflash solve that?
A: Possibly. Most deceleration popping on the Austrian bikes happens on the 12-19 enduro machines and is caused by the PAIR air injector pump which can be removed in a race bike conversion.
Q: What about removing the t-stat
A: We ride our bikes year around and in all weather and temperature conditions, so for us leaving in the t-stat means a better running bike in any and all conditions. If you primarily ride hard-enduro or in temps above 65-70f you might consider removing it, otherwise leave it in.
Q: Will my fuel mileage drop?
A: Possibly. You’ll be having way more fun on your bike so you’ll likely be riding faster and with more spirited throttle inputs and that will have an effect. But we also have an economy cruise tune and that should keep things similar to stock.
Q: Should I break in my engine before doing the flash?
A: We break in all of our new bikes on a tuned ecu and find it offers better ring sealing and overall engine durability than with the stock tune.
A: No, our tune won’t trip the CEL on any bikes.

A: We break in all of our new bikes on a tuned ecu and find it offers better ring sealing and overall engine durability than with the stock tune.
Q: I currently have a piggyback fuel tuner on my bike, when I install the remapped ECU should I remove that?
A: Yes, the tuned ECU will run entirely on it's own after the reflash and the tuner can be saved or sold.
Q: If I remove the intake reeds will my boot collapse in on itself, and do I need one of those aluminum tubes that claim to prevent this and improve power?
A: The myth of collapsing intake boots propigated on certain YouTube channels is a complete sales fabrication and false claim, and our testing demonstrats mixed results with an intake airhorn.

If you have special return shipping instructions include these in writing.
Q: I'n not located in the US, will you still email me a call tag for my ECU?
A: Unfortuantley no, international reflash customers will need to ship the ECU to us and we'll ship it back once completed. There may be additoanal shipping charges and import duties owed for the return. If you have any questions about any of this please reach out to us for more clarrifacion.
Q: What’s the expected wait time for my ecu to be returned?
A: Depending on your proximity to Las Vegas, ground shipping may take 1-5 days. We'll return most ecu's in one business day, however based on seasonal backlogs this may take up to three. You could plan on the same 1-5 days for the return shipping from Las Vegas to you. NOTE that all shipping times mentioned here are ESTIMATED and external impacts like carrier interruptions or unexpected delays due to work force shortages, holidays, weather etc. cannot be anticipated and are not our responsibility.

Q: Will this ecu remap void my warranty?
A: The warranty is administered by your local dealer and your relationship with him or her will go a long way in your success with any warranty issue. The remap in itself won’t impact the fitness or serviceability of your warranty, but things like aftermarket mods or parts, maintenance records and general bike condition may. If you have any specific questions about your bike and mods you’d like to make we suggest you discuss those with your dealer and consult your owners manual.
Q: Regarding the 'coming soon' features, when those are available, will I be able to send my ecu back and have those enhanced features programmed in?
A: Yes, we'll contact you via email with notification they've been released and with any applicable information about cost impacts and shipping details.
Q: I've heard that there will also be a 'tune at home' option using the Dyojet PowerVision device. When will that be available?
A: We're currently finishing the details on that program and it should be on the site no later than early April if not sooner.
Q: Do you have an option for express flash / overnight shipping or core swap?
A: Yes, please contact us for more information. You might also consider the ‘tune at home’ program which eliminates the need to remove the ecu from the bike.

RIDER REVIEWS:
"At the sake of sounding like a know it all, I've been riding dirtbikes for 45 years, former club racer, MX juniors champion, SOCAL desert series rat, and on and on. I know what a good running bike feels like, how it should pull, how it should settle after it comes off of the power, how it should ride in all situations from low end all the way to the redline - and you guys got it right. Something tells me this was tested with factory KTM riders because this tune feels every bit as good as the secret 350 bike I rode in Barstow a few years ago. Nice job fallas. Taco Moto customer for life here."

"I just got my first ride in with the Taco Moto "race-power" ECU tune (done with the Power Vision 3 self tuner!)
Bike is a '24 501s with end cap change and reeds removal.
I have been using the JD tuner (NOW FOR SALE), which I would say is VERY good for the money.
That said, this Taco Tune absolutely rips!

That said, this Taco Tune absolutely rips!
At first I thought power was roughly the same as the JD (which is night and day from stock,) but then I realized I was riding a gear or two higher, which the tuner would never let me get away with.
The power is also very SMOOTH and I had no issue with flameouts, hesitancy, or backfiring while riding either.
I am very impressed, and looking forward to having access to different maps for other applications."

"I wanted to circle back after giving the TacoMoto ECU reflash a solid shakedown at the 2025 Biltwell 100. I’m running a 2019 Husqvarna FE501, it's desmogged, the reeds are removed, and I’ve got the stock exhaust with a Fastway end cap.
When the bike was new it was hard starting, stalling on descents or long flats, and occasional surging at steady throttle (especially on the highway). At the time, the only solid option seemed to be the Vortex ECU, but I wasn’t ready to spend that kind of cash. I went with the JD Jetting piggyback tuner, which helped reduce flameouts, but didn’t fully solve the hard starts or surging.
When I heard TacoMoto was releasing a mail-in ECU reflash, I knew it was the move. I’ve had great experiences with your other products and felt confident you’d stand behind the service.
I mailed in my ECU using the prepaid label, and just a few days later it was back—complete with stickers and root beer barrels (classic TacoMoto touch). Reinstall took less than minute. After bolting the plastics back on, I hit the starter and—VROOOM—the bike came alive. It immediately sounded smoother and crisper. I was already feeling like I had a new machine.
Fast forward three weeks: I’m on the start line at the Biltwell 100. Three 25-mile loops of desert brutality. The bike did not skip a beat.
Smooth, consistent power
No decel pop
No surging
Cold starts = no problem
Fuel use only increased slightly (likely due to race intensity)
The day before the race, I did a 40-mile warm-up ride and really noticed how much more refined and rideable the tune was.
Bottom line: The JD tuner helped, but the TacoMoto ECU reflash transformed the bike. If you want your machine to perform the way it should—whether you’re trail riding or racing—this is 100% the way to go.
Huge thanks to Mike and the TacoMoto crew for dialing it in. Couldn’t be happier with the results."

I mailed in my ECU using the prepaid label, and just a few days later it was back—complete with stickers and root beer barrels (classic TacoMoto touch). Reinstall took less than minute. After bolting the plastics back on, I hit the starter and—VROOOM—the bike came alive. It immediately sounded smoother and crisper. I was already feeling like I had a new machine.
Fast forward three weeks: I’m on the start line at the Biltwell 100. Three 25-mile loops of desert brutality. The bike did not skip a beat.
Smooth, consistent power
No decel pop
No surging
Cold starts = no problem
Fuel use only increased slightly (likely due to race intensity)
The day before the race, I did a 40-mile warm-up ride and really noticed how much more refined and rideable the tune was.
Bottom line: The JD tuner helped, but the TacoMoto ECU reflash transformed the bike. If you want your machine to perform the way it should—whether you’re trail riding or racing—this is 100% the way to go.
Huge thanks to Mike and the TacoMoto crew for dialing it in. Couldn’t be happier with the results."
