Tps-sensor and map


I wondering is it possible to adjust Throttle Position sensor for about 3% at idle using ecueditor enginedata screen. And also adjust IAP->TPS map switching point for smallest value which is, if I remember correctly, about 3%. This is because there is MS TPS-map but no second IAP-map so I cant tune for two fuel example e85 and gasoline! But if I can eliminate IAP-map in this way and use only TPS-maps, maybe this is possible?

 

Bike is gen1 for street use so how about runnability with TPS-map only? 

I would happy to hear if anyone has any experience with this.

I'm sure you could adj the TPS for 3% opening at idle.. but your idle may be through the roof...ecu editor allows 2% switching...but you could adj. it to 0 with romraider...and tune everything off the TPS map..

I wouldn't adjust the TPS to 3% at idle because it will run richer everywhere all the way up through the TPS range (IE. ECU thinks your closer to 25% column when butterflies are only at 20%)...

I had this happen on a Gen2 that came in for a ECU Tune and as it turned out that bike WAS idling at 3% TPS and it was rich everywhere from the get-go up through and including "normal riding conditions" = it would have taken a LOT more tuning to get the A/F right everywhere, rather than adjust the TPS to 0% Idle first...and yes it did lean it out when I re-adjusted the TPS (didn't run way rich anymore)...

If you want to try running on mostly TPS only, you still need to Tune some on the IAP Table (using Engine Data) because ECU doesn't "swap from IAP to TPS like a on-off switch"...

...JM 2-cents...
