Nice! I fixed my PFC issue too Was a blown fuse. Cant wait to get mine tuned at hittman and see what I get

Can I ask what mods you currently have to get what you got? PM me if you dont want to say publicly and Was it a power tune or a complete?

No worries mate my mods are:

1995 RB25DET

Standard Turbo

R34 GTT Intercooler

Adj Exhaust Cam gear (set at 3 1/2 deg ret)

CES 3" split dump pipe

Magic cat

Custom 3" into 2 x 2 1/2" exhaust (very similar to Apexi N1 Dual muffler)

GTR Fuel pump

Apexi Power Intake Pod filter (with custom cold air partition)

hi ryno

i would be interested in talking more about your tune. max power is only one aspect of an ecu tune. theres lots more to be gained in the midrange and the important parts of a tune

Hey Paul,

I am rather fussy with my car, so I researched tuners for a while before I decided to go to Hitman, and I must say he didn't disappoint.

He spent about the same time tuning the cars economy, as he did max power. In fact the max power was never much of a drama, as the first run (with the standard Power FC maps) made 183 kw. I'm very happy with the tune, the car is now smoother than it has ever been, has more power, and uses less fuel. Perfect!

Hey mate,

It sounds like a few people have been having this problem - here are the places to start looking:

1. Check all fuses - twice!

2. Wire in a direct 12v from the battery to the battery input on the ECU (pin 58)

3. Check earth wires (pins 60 and 50)

4. If it's still not working start checking all the other wires, for a break or something connected where it shouldn't be.

Hope that helps

i found the problem it was one of the relays that is up by the computer plug was missing. thats strange that it would run on the std comp but not the power fc. its running beta than ever even with std tune.

That's good to hear mate,

It's amazing how tolerant the standard computer is to blown fuses, broken wires and missing relays! But it can make plugging in the Power FC a nightmare. I'm just glad it's all up and running now, if I never have to solder a wire in my car again, I'll be a happy man.

please let me know what fuse was changed. will add to FAQ

Good to here I have a r32 with a rb25 in it as well but with the stock comp in it still, fingers crossed I hope the power fc works in it.

buy the way where is (Hitman) located also that power in a r32 should just do a 12 sec ET.

All my fuses were fine... I had a shorted out earth wire in the loom (the one from pin 60)

Hitman is located in Penrith, he has a web site (www.hitman.hm) though it appears to be down at the moment. His contact number is: 0417259391

I have done a rb25 swap the Hicas needs a speed signal. my car does not have the speed limiter it's bean tested a few times LOL and my Hicas light turns on and off when it fells like will the Hicas still work or should I put a lock bar on it I don’t want the speed limiter.

I had the same trouble with my car... I decided to remove the HICAS and install a lock bar. By doing so you pull about 20 kg of weight off the car, and then I fitted a R33 power steering pump.

You can disable the HICAS (so you don't get that light coming on) by disconnecting the smaller of the two plugs that go into the HICAS control unit - which is in the boot, beside the rear speaker amplifier.
