KTM & Husqvarna 2-Stroke TPI ECU Flash - 2018-2021

We have quietly been spending a lot of time in the warmer months building performance products around the KTM & Husqvarna lineup of TPI (transfer port injection) off-road motorcycles (150, 250 and 300). We are also offering a performance head to pair with the flash, something we *heavily* encourage. If purchased together you will receive a discount. 

The Problem

From the factory, the KTM/Husky engine maps are built around passing the European emissions laws (EURO 4). We have noted the following issues:

• Lean running motor. The motor can run too lean, especially from idle to 1/2 throttle
• Erratic on trail. The OEM map can cause the bike to sputter in parts of the throttle
• Excessive pipe bang on deceleration
• Uses a very small amount of 2 stroke oil. Some riders have already had durability problems as a result. We can turn the oil pump up slightly, resulting in a safer running motor. 
• Performance is a bit flat. Many riders have been out climbed and hole shotted by their buddies on the exact same bike with a carburetor. 
• Hard starting in certain situations

Despite these OEM mapping woes, we firmly believe in the TPI system as the future of 2 stroke dirt bike riding. Simply put, fuel injection gives us more control over the riding characteristics than we could ever get out of a carb'd setup and we've been able to extract an immense amount of performance through building a map for performance & quality of ride, not European emissions. 

Drawing on over a decade of tuning & modification work in the two stroke snowmobile world, we have been able to successfully address both performance and ride quality issues using the stock ECU in a way that no other tuner has been able to accomplish. 

We are the *only company in North America offering a reflash service. Dollar for dollar it is the best money you can spend on your TPI*, we offer all the performance of a stand alone ECU while retaining all OEM serviceability! We have invested hundreds of hours into our proprietary flash process, and can assure you it is easier, more affordable and draws on our extensive understanding of fuel injected two strokes!*

Once you've ordered you must download this form and include it with your ECU.

Highlights:

• 100% software based flash; we do not physically alter the ECU in anyway.
• Much better engine characteristics from idle to 1/2 throttle. 
• Smoother power delivery.
• More torque at low/mid RPM.
• More HP at high RPM.
• Less pipe bang on deceleration.
• Safer air fuel ratios (not lean).
• Additional oil injection (more oil = happier pistons/jugs/bottom end)
• We suggest you use the stock pipe. We will be testing & building maps around both the FMF and Pro Circuit pipe in the near future. Our current offerings may work, but we have not put enough time in to definitively verify this. 
  
• We alter both maps on the bike which can be selected via the bar mount (or plug if you did not install the bar mount).  The configuration remains the same (one is less aggressive, one is more aggressive)
• We offer three map configurations. Hard Enduro (most torque down low, easiest to ride) Trail/Everything (overall; suitable for most riders go with) and MX/Track (Most aggressive, highest output; runs a little hotter - not suggested for slow speed trail riding)

Compatibility

• We are offering maps for the 150, 250 and 300 TPI models from 2018 through 2021. 
• This includes *all* models of TPI bikes from both KTM and Husqvarna.

Future Releases

• We will be offering an aftermarket head with swap-able domes for this bike in the very near future. Swapping the dome will change the compression and help our mapping work even better. The dome you chose will depend on your use. Expected early June.
• We will be offering remote reflash services (you reflash from your own laptop) very soon and will be offering the required hook-up cable on this page.  Expected early June. Cable can be shared with your friends. One map purchase = One Machine.

Other Caveats

• The stock ECU will still connect to your dealer diagnostics. In fact, we do not believe the dealer will even be able to see any changes have been made.
• We suggest you leave the powervalve settings 100% stock.
• For off road use only!
