Nistune Forums

I have nistune on my GTR33 with BNR32 ECU, Nismo 555 injectors, R35 AFMs, DW450 fuel pump and fuel pressure set at 3 bar (slightly higher than 2.5 bar of OEM). Everything is fine except when starting cold in the morning, the idle tends to slump and sometime stalls after start. Yet, it will sometimes...

I would like to look for quick answer to the following quesions concerning the GTR33 (RB26) tuning:

1) How to select which cells to do autotune and which are excluded;

2) Apart from the fuel map and timing map, what other tuning functions are related to sudden acceleration;

Thanks so much.
