I've thrown the pfc in darrens and it does the exact same.

When darren brings down his stock ecu I will find out what else is gone in mine, hopefully nothing but apparently its common for the ignitors to go.

Hmm it doesn't sound too good. But it is possible that it's fixable.

That diode that you found is the main power protection diode that all cars have to have in their ECU. if you reverse power the computer that should take the full brunt of it to prevent damaging everything else. It is possible that it is damaged without it being burnt, & could be stopping the whole thing from running.

Is there anything actually working on it at all? It could be this diode if that's the case.

Also that does look like a blown track on the TPS power feed are you sure it's the power feed though. Is there exposed copper at either end of the break? If so yeah it's been zapped & needs joining back up.

Sorry I forgot to update this thread. >_<

I sent the PFC in to force electronics, they checked it out and replaced various resistors and capacitors.

It now works PERFECTLY!!!! :sick:

RE: Pin 57, that is indeed a cut track as Bl4ck32's AP Engineering PFC also has been cut.

After a little investigation it appears the R32 pfc is based on an early r33 pfc. Pin 57 on the R33 is an exhaust heat sensor, where as on the R32 it has something to do with throttle input, apparently used in the auto's.

So AP have cut the track to be on the safe side it appears. :D

Somewhere like Petroject would have been my first choice. These guys specialise in repairs to engine management systems & are more likely to be able to help you to diagnose the problems with consultation & having electrical information of many vehicles also enables them to figure exactly what circuitry has been damaged etc.

They also have a special test bench which enables them to actually run the ECU & check what's working & what's not etc. They deal with a lot of the trade & the guys there have a lot of experience between them. Most of the time the only reason things can't be fixed is if they don't have spare parts for a special component (eg a main microchip), or the board is too fried, or if it's simply uneconomical to fix.

For the kind of repair you needed done you could get away with going to Force, but if it had become any more complex than that I doubt they could have done it.

      Leak from Tokico BM50 Brake Master Cylinder

      HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.

      The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.

      Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?

      R34 25GT Engine Light 21

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol

      No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
