Yes its possible... you can flash the tune to the ECU and then disconnect the ERM.

My bike did the same thing. Did a powervalve reset, check engine light went away.

If you perform a powervavle reset it should stop the code from coming back. There were a very limited number of covers manufactured which 'may' have caused the PV to generate a fault code. Performing the PV reset will normally fix the issue.

@@TwoStrokePerformance have you had issues with the set screw fouling the PV cover??? I can see where it's been hitting???

Yes generally the green map is leaner than the white map, but ti does vary. If you want to experiment you coudl use Basic Tuning to remove say -3% fuel on teh white map and see how it feels. If it feels OK you can go a bit further.

@@booger65man thanks for the detailed reply. It has highlighted the reason for our mutual frustration and finally gives us something to work with… you mentioned South Bay Moto Performance… South Bay is a distributor of ours in the USA and although we work closely together we are not the same business. We don’t have access to their emails or sales records. If you purchased from South Bay Moto then you did not purchase direct from us. This would explain why we have no record of your sale or emails. Steve at South Bay is renowned for excellent customer service and it is very surprising to hear your emails went unanswered. I will forward the details of your complaint and discuss with him further.

Normally that will happen if theres a fault code present, or if the idle is set too high. Check and clear any fault codes and make sure that the TPS voltage is 0.60v or less at idle and try again.

@@TwoStrokePerformance thanks for your opinion, i aplicated your instructions and finally my 2t pump can priming normally thank tou 🙏🏻👍🏻

If you leave all values at zero you will be flashing the TSP tune to the ECU without any further changes. In this case (when everything is zero) the preset label is 'TSP' because you are flashing our tune as we intended it. If you change any of the cells you are now flashing a modified version of our TSP tune (with your changes overlaid onto our tune) and in this case the preset label changes to 'Custom'. Likewise if you choose one of the other preset labels, eg 'Softer' if will flash our TSP tune with the Softer changes overlaid onto it. In all cases you are flashing a TSP tune, its just that you may have chosen to make some changes to it or not.

@@TwoStrokePerformance Makes sense, thanks!

I would suggest carefully checking wiring to the PV servo. If possible swap the servo for one off another TBI bike and see if its still happens. We have had the same issue on one of our shop bikes and it turned out to be a wiring fault. Another possibility could be carbon build up stopping the PV from reaching its limits.

I reset code, then PV and TPS again and then went for a ride, code is staying off now. But the dead Spot/BOG off initial throttle 0-15% is not going away. Then it opens up and pulls like crazy. But nothing on the Bottom.

@@christophernapolitano8404 i would still investigate the PV. Lack of bottom end power then strong mid/top are a common symptom of a powervalve thats set too high. There could be something stopping the PV from reaching its correct lowest point. Even though you did the PV reset it may have just reset the low position to something higher than it needs to be. eg. if carbon was stopping it from reaching its correct down postion the ECU just resets the new (higher) position as closed because thats as far as the PV can travel.

The ERM is currently a single license device so it can only be used to tune one bike at a time. If you want to leave your current ECU tuned and take the ERM to a new bike you can purchase a reset through your account at tsp-erm.com At some time in the future we will be releasing a version which allows multiple licenses, however we dont have a timeline for that yet. It will most likely be later this year or early next year.

@@TwoStrokePerformance how much is the reset?

​@freqchen $350. Better off buying a 2nd ERM. I just installed my kit this evening. ERM is super easy to use.

unfortunaely you cant use the stock on one colour and TSP on the other. Each time you load a 'tune' is comes with 2 'maps' (white and green). The stock 'tune' has its own white and green maps and our TSP tune has its own white and green maps. You can use the ERM to modify either the white or the green map on the TSP tune though. Doing this allows you to make either map run almost any way you like.

Yes, weve had virtually every tune on the market sent to us by customers at some stage or another so we have tested pertty much every option.

No, you only need to do it the first time you pair the ERM with the ECU. Once it has been done the first time you can then make changes with the ERM and you wont have to do it again. The only exception is if you do a top end rebuild and strip down the powervavle, in which case you would perform the powervavle reset again, or iof you decide to manually roatate th TPS to another setting, in which case you would do the TPS reset again.

@@TwoStrokePerformance Thanks and good to know!

No, you can fit it to a stock bike and its very effective at adjusting the tune.

They sure are! Contact Riley at BRC Racing... brcracing.ca/ He has ERMs in stock and ready to go.

@@TwoStrokePerformance absolutely thank you will be ordering so glad I no longer have to ship out and can keep riding keep up the good work

Probe the Black and Yellow/Red wires on the back of the TPS plug. With both the red and yellow throttle body adjusters backed all the way out you need to set the TPS to 0.40v. If it requires adjustment loosen the torx screws holding the TPS in position, rotate as necessary and then re-tighten until 0.40v is achieved.

@@TwoStrokePerformance When you first back out the yellow know, do you press it in and then back out?

No dont press it in, just back it out.

Nope.

Contact MX Guards in Hungary, or Rutherford Racing in the UK. They both have stocks of ERMs.

Not you wont have done any damage. We have updated the process for several reasons. This most recent update, which now includes the adaptive value reset, has come about to bring the process in line with the KTM manual. The reality is that the vast majority of ECUs already have 0.40v saved as the TPS baseline value. For these bikes the adaptive value reset doesnt change anything. Rather than telling some people to do it and others not to, we have simply now said to everyone to perform the reset as a safeguard. The reason we are confident in this process is that we have a database of hundreds of original ECU tunes from ERM customers and can see exactly what value they are already set to. Virtually all of them are already at 0.40.

What is the problem you had? Did you email us directly here in Australia, or was it through one of our resellers? If not email admin@twostrokeperformance.com.au and we can help.

Yes the TPS reset is the same as resettign the adaptive values. Its the same process. It teaches the ECU the new closed postion of the TPS.

No you only need to do it once. Think of the ECU as containing one 'tune', and the tune has 2 'maps' within it. The reset applies to the tune and so therefore impacts both maps.

Awesome thanks 👍

Yes it can

Its actually very easy if you follow the steps in the videos. Usually takes about 10-15 minutes in total to setup the ERM and start riding.
