Hey Guys, I'm finally getting my car to the point i can start thinking about ECUs. I've got a 16-bit TT ECU and harness that goes with my 1996 VG30DETT, but after reading the Nistune forums looks like a couple of people have had issues tuning this ECU. Anyone here running a Type-3 nistune? Also with the turbos i'll be running i should be able to see around 550rwhp and apparently this is a bit past the limit of the stock AFM. Is it the size of the pipe that is too small at this level or is it the sensor runs out of resolution? Would a dual intake be the way to fix this? Does anyone have a tune for this ECU running 740cc injectors too?
Dean (bRACKET) has a 16bit ecu with a nistune. It was installed by Trent at chequered tuning in Melbourne. Maybe PM him to ask if he had any problems.
Yeah thanks rob, i was just wondering what was getting maxed out and whether halving the value fixes the issue if it is indeed the sensor maxing out. Since i am chasing just over the limit of the MAF i was thinking the twin solution might be good enough. I'm trying to do it on cast pistons though so good tuning will be essential to the motor surviving. So if running a duel intake is a dodgy way to get the extra head room compared to going to a MAP sensor, it probably isnt a good idea. bRACKET's car is N/A isn't it?
I don't think there any restriction having two AFMs -they must be 80mm or so in/out? MAP sensor is much "simpler" in terms of plumbing and components
My Z has a Nistune board in 16 bit ECU. I'm also using a Selin dual pop intake. No issues here (so far). I'm hoping for 550rwhp or thereabouts.
Yeah this really is looking like the way to go especially since the Selin thing is cheaper than an S-AFC. I have a FMIC though and i dont think mounting the filters behind it is the best idea of cold air induction, on the other hand the intercooler never seems to get hot. I guess that means the air behind it usually is though haha. I am still thinking of putting the filters down in the corner ducts of the front bar. When it was running a Microtech thats where they were located.
