Good Morning Nistune Forum.

I need assistance with my SR20VE my car is going lean at part throttle tip in , Hitting up to 17.1 causing bogging before acceleration .

I don’t want to use the Accel Increase fuel map as I don’t want the car to access the last Fuel and timing map, I want it to run through the range.

I have tried the throttle enrichment – fast with no success and the TPS enrichment trigger with no success.


All I need is the map where the car enrich the Injection on TPS Tip in

Are you using a DE or VE ecu?

try adjust the ttpm max to all 255 values.. that fixed my problem.

I will try and get you one

Ok, Guys, I found the map "TPS Enrichment trigger".

I now need to find the map that controls how much TP is added on light throttle tip in

Light throttle wont use any other table - just the fuel map

Heavy throttle uses the TPS enrichment to determine if to access last columns on the fuel map
