TSP ERM Power Kit – 2020+ KTM & Husky 150cc TPI

1 review Add your review

This is the ONLY complete solution currently for sale on the market that addresses all the necessary TPI issues – head, ignition and fuel. It is also the MOST COST EFFECTIVE solution by far. All other solutions are either more expensive or only tackle part of the problem. With the new TSP ERM, you also get a handheld device that has the ability to show live data, read and clear fault codes, data log, make fuel/ignition/oil changes (with Pro or Pro+ mode activated) plus much more!

NOTE: With the purchase of an ERM, you DO NOT need to ship us your ECU. Once you receive the ERM, you will use the ERM to download the correct maps for your bike, and you will flash your own ECU using the ERM.

Introducing a world first in two-stroke tuning with our brand new package – the TSP ERM Power kit, featuring the new TSP ECU Re-flash Module (ERM )!

This is designed for all 150 TPI KTM & Husky models from 2020-current.

This package will transform the power delivery of your 2020-on TPI, it includes the following:

  • A handheld touchscreen ERM device which comes with a free downloadable TSP ECU Tune to suit your bike & relevant TSP modifications. For a full breakdown of this product, check out the TSP ERM website.
  • A billet TSP machined cylinder head which is higher than stock but still very safe for 91 octane pump fuel.
  • The TSP head includes a complete head gasket kit
  • A new NGK spark plug, better suited to the improved power the engine makes with this kit
  • TSP idle bolt mod package (bolt and spring) so you can set your idle speed correctly after setting your air screw

The TSP ERM device is an alternative to our current ECU re-flash service, meaning you no longer have to mail in your ECU. This means no down-time on your bike! Furthermore, you now get a handheld device that has the ability to show live data, read and clear fault codes, data log, make fuel/ignition/oil changes (with Pro or Pro+ mode activated) plus much more! The ERM also comes with a mount kit so you can have it mounted to your handlebars, or it can be used handheld and easily kept in a toolbag.

Our 150TPI kit increases power throughout the rev range, making approximately 2hp more up top and 5 hp more through the mid-range compared to a stock bike,  making it a weapon offroad.

This package makes an astonishing difference to the TPI, and when you download your free TSP Map to your bike using your ERM device, you will achieve:

  • Much more torque at low/mid revs, where you need it most, with a nice increase in power higher up in the rev range as well.
  • Drastically improved 0-1/2 throttle performance
  • More oil than the stock maps for improved reliability
  • 2 ignition maps: Hard and Soft. The stock map switch works like normal to select between the customized maps, or you can use our TSP Map switch. The hard map is our standard ‘full tune’, while the soft map is designed for really soft inputs in harsh conditions, or deep sand riding to help protect your engine.
  • Much smoother, crisper power deliver at part throttle.
  • Much less ‘pipe bang’… this is the annoying “dang, dang, dang” noise the engine makes on deceleration. Its generally harmless but very annoying and makes some stock TPI bikes unpleasant to ride at times.
  • Safer air/fuel ratios at high rpm and large throttle openings so the engine is safer during prolonged high speed running
  • Better throttle response
  • You can ride in a higher gear with lower revs in many situations and use the extra low end torque to get you places with less wheel spin and much less clutch work
  • Ability to tune/adjust your own oil/fuel/ignition maps with our Pro or Pro+ Modes.

There is no risk to reliability with this setup! The ignition maps, air fuel ratios and combustion chamber designs are similar to those we have run very successfully for years.

In order to have the skills to adjust the stock ECU data, we have spent hundreds of hours developing our own process for accessing, changing and reloading the ECU data. TSP was the first to develop a tuned package for the TPI bikes and we have years of experience testing and tuning fuel injected 2 strokes prior to the release of the TPIs in 2018. Now we have achieved a product that puts the power literally in your own hands!

The ERM unit pairs with your standard ECU,  and all ECU features work normally including oil injection, fan and warning lights.

We supply installation instructions plus recommended settings for the air screw and power valve preload.



* Map adjustments on the TSP ERM are available after purchasing the optional Pro or Pro+ Modes on the TSP ERM website
