So i got a Central20 ECU, and it rocks, now that i fixed the timing. However, when i first put it in the base timing was 10 deg, not 15 as per teh old one i just took out, i had to move the CAS about 3 mm to get it back to 15 deg, and DAM what a differance, is this normal. The car is bonckers. I LOVE IT.

ALSO, The car takes longer to warm up, so i presume it's running a bit ritch. The knock is as per old standard ecu so all good there, i don't think it's pinging, so far so good.

IF the ecu was causeing some engine issues, how long before i can tell that it's wrong?

Hi

Sorry I don't know if i can help you but you might be able to help me. I have also got this Central 20 Ecu in my R33gtst and i am having probs with it. I think it needs to be remapped or something. when i put the car on the rollers it says that the A/f jumps straight to 10 or lower. I think this is meant to be round 12 - 14 or something. I have been told that there is no one in aust that programs these ecu's. Where did you get yours from and where did ya get it mapped. Any info would be great.

i got mine given to me, and i have not had mine on the rolles as yet.

they are all different, form what i know, but they can be remaped and DR drift has done one or two, some come coded so you can't other you can.

I have an SAFC II so if i need to do anythign with the fuel maps i will.

I also have a fuel pressure reg and i bumped the fuel pressure up a bit just to be sure.

the AFRs you have are LOW wich is bad, so you might need to do something or your damage the car. Mine feels ok so far, but i will check it out soon i hope, all i know is it rocks, i mean the car is soo daaammm fast now.

      Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.

      Recomended Coolant For Gt T R34

      By silviaz · Posted

      What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.

      Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!

      R34 4 door side skirt identification

      No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
