Dear all, I'm using the Nistune on my BCNR33 with BNR32 ECU. The car is currently running fine with Tomei system 2 map for 555cc injectors & Poncam B, and just waiting for my further tuning.
I notice that during the warm-up stage (below 60C), the timing will always retard to 10 BTDC whenever I floor the throttle (under load). The timing limit will be gone when water temp reaches 60C, and the timing can freely jump from 20-45 BTDC according to the load. Actually, same also happened on my Mines Stage-1 ROM.
Is there any way that I could get away the timing limit earlier say at 40C or 50C?? tried to adjust those enrichment coefficiency but can't make any difference.
thanks!
