Might just check the wiring and voltages and bridge it out if I have to. But I think if it thought it was neutral all the time my vct wouldn't work and it definently does. Worth a shot anyway

I've ordered another power fc so that I can rule out the unit once and for all. I'm pretty convinced its a unit issue because of my old power fc running fine.

Have just checked all the wiring from the CAS to the ECU. Everything is perfect. At this stage I am pretty convinced its an ECU fault. If the new ECU works fine I'll have to find somewhere to send the faulty one for repair.

So new ECU has the same problem. I'm really stumped by this. I can't believe noone else has had this issue. If anyone happens to have a brand new Power FC (V7) and wants to help me out, please PM me, would like to compare some data if possible

Although I have tried the base map with only my injector settings changed. Perhaps if someone has a tune that seems to work fine then I can load it into my Power FC and see how it goes. Preferably something with 555cc injectors and a Z32 AFM.

I'm really stumped I've tried just about everything :(

The issue was present in another S1 R33 that I tried it in but because it had far less mods you didnt notice it as much, could just visually see it on the hand controller that the timing was 10 degrees below were it should be and was a bit erratic.

hey what did you end up finding on this CAL? I have a V7 and it does the same thing, goes full rich for a sec or 2 on gearchange/neutral before coming back up in the afrs. I just thought it was a maf reversion thing and hadn't thought too much of it until reading your thread.

    • I’d love to find some where that can recover the dashes to look brand new and original. Mine has a very slight bubble, nothing compared to some I’ve seen though 
    • $170K. I asked one of the guys there as a joke if that price was just for the passenger seat as it was where the price sheet was... he tried really hard to crack a smile 😄 He also mentioned that every single part of the car was inspected and either restored or replaced with a new or as new part, or made from scratch. The interior was incredible, every inch like a new car.
    • Time for a modernisation, throw out the AFM, stock O2s, ECU into the e-waste bin. Rip out the cable throttle, IACV, pedal, etc. into the scrap metal bin. DBW, e-throttle, modern ECU, CANbus wideband, and the thing will drive better than when it left the factory.
    • I agree, don't go trusting those trims. As I said, first step is to put the logger away, and do the basics in diagnosis.   I spend plenty of time with data loggers. I also spend plenty of time teaching "technicians" why they need to stop using their data loggers, and learn real diagnostics.   The amount of data logs I play with would probably blow most people away. I don't just use it to diagnose. I log raw CAN data too, as a nice chunk of my job is reverse engineering what automotive manufacturers are doing.
    • I'm aware, but unless you're actually seeing the voltage the ECU is seeing and you're able to verify the sensors are actually working I find it hard to just trust STFT/LTFT. I will say, logging the ECU comes naturally to me because it's one of the lowest effort methods of diagnosis and I do similar things in my day job all the time. Staring at 20+ charts looking for something that isn't quite right isn't for everyone. NDS1 allows you to log almost everything so that's normally what I do and then sort out the data later.
