Throttle flow vs opening

Post by D33@+H-Kn1gH+ »

How should I adjust the values for the J35 throttle body flow? I have the throttle body installed after the supercharger

From what J35-Engine do you have exactly the Throttle Body?:

Regarding the FP help:
Calibration > Throttle > Throttle Flow vs Opening:
In some situations the ECU will need to know the air flow past the throttle body for a certain throttle opening.

I recomment to alter also the Error Conditions > Maximum plate deviation (P2101) a little bit!
increase the TPS (%) values from: Angle 1.9 to 15.0

But I recomment to leave it stock and review a log to see if adjustments are necessary...! Normally the stock TB is good for 600+HP builds ;)

I bought the throttle body from tegiwa. As far as I know the throttle is the same as the FD2 type R

Then i guess i shouldn't make any adjustments. I read in the FP help that it needs to be altered for any bigger throttle body. Now with the J35 I went from 61mm to 64mm outlet so I thought I should make some adjustments

Then try the values from a FD2 calibration or the values from a Honda/Acura, where has a J35 engine!
