Hey guys,

I know this question has probably been asked before but I could not find anything in the search engine.. Anyway..

Is there a Difference between Apexi's Power Fc's for the R33 RB25 DET series 1 and Two Engines??

eg. Does the later series 2 motor that has 'vct' use a different model Power Fc??

I am asking this question because I am in the market for a Power fc for my 97 mdl' RB25 DET.

Any help at all is very much appreciated guys...

Thanks..

Ash

for those that wonder why its the same unit;

the changes between the series 1 and series 2 RB25 are done on the engine side

that is, not on the ecu side, so the difference in coils, tps, afm etc etc are engine side

so regardless of ecu used (s1 or s2) its all the same

the series 2 coil setup is different, but its changed locally on the engine side so the remote "ecu" side is the same if that makes sense

much like the afm setup, they run different airflow meters, but its local wiring on the "engine" side thats changed around, on the ecu side its the same

ie: the pinout on the ecu side is the same and so to is the ramp, load, voltage scale etc

but there are differences on the map layer for the s1 and s2 ecu's

i tried a series 1 remapped ecu on my s2 skyline and it ran like poo

it felt like i was driving through mud

    • There's a huge reason manufacturers are tuning in dead flat torque curves... Make them reliable (and more drive able)
    • What HVAC actuator is under the steering wheel? Do you mean on the RHS of the centre console, immediately to the left of your shin? If so, then yes, it is probably that one, because that is the mode door actuator, and from what I know, it's still a pain in the arse to replace. I don't know about whole dash out, but you certainly have to rip into the centre console section. I don't know if it's covered in the workshop manual, as I haven't spent much time looking at those parts of it. (and by "the workshop manual, I mean the R32 GTR one, which is the most comprehensive one we have, and it should be similar enough between that and later cars to serve as a guide).
    • ...oops. forgot the TCU end...
    • No I got mine from a friend that had fabricated one … but I had to fit it to my setup which was a hks turbo setup. His was a Garrett -7. So one of my turbos was not a flange for one side … then I had a leak in the welds I had to find a weld shut … in the end the setup was decent priced but I spent a lot to get it fitted. A couple companies I checked would make it but you’re talking 7-9k aud with titanium. No joke mine was 6-7k even second hand after I had to fit it in Hong Kong … labour is expensive here. 
    • I'd just like to restate that I don't think anyone here is actually hating I recently sold a car part to a guy who was building a forged auto R34, with MV stall and aiming at ~450kw. I told him that I'm him, from the future and to stop after it explodes once. I told him I knew he won't listen the first time, and that's fine. But if my predictions do come true - Change direction faster than I did. I also said it's probably no coincidence that the dyno plot of a reliable turbo engine starts to look a lot like a N/A motor. :p
