Supraguy Posted September 11, 2003 Share Posted September 11, 2003 Wow. Had a nice little suprise today when I went to take a peek at my ECU wiring today. Pulled back the carpet to reveal I had a Blitz Access ECU PC-23710T installed in the car!! Anyone have any stories good or bad about these things? I am wondering if its got anything to do with a couple problems with my car. #1 Fueling- The car seems to be running very rich. Little bit of light smoke when giving it alot of throttle. (Noticed by Roy on last weekend's London cruise) Is there any way to tone down the fueling on this ECU, or will I have to use my Apexi S-AFC II that is on order to sort it? #2 Trac off Light Flashing- It was pointed out that it could be a faulty speedo conversion kit, so the speedo kit was removed completely (running in KMH) and the fault still persists. On a cold start, when you first turn on the car the Trac Off light will flash. There will be no MIL, Check Engine, etc.. nothing else lit. This only happens maybe 1 in 10 times. But, the worrying part is the fact that the car will not go in reverse when its flashing. To clear the fault, I have to turn off the engine for a few seconds and it goes away. It always comes up on cold start up, and never manifests itself when the car has already been up and running. Any ideas?? Link to comment Share on other sites More sharing options...
lovatt Posted September 11, 2003 Share Posted September 11, 2003 i have the same ECU, its probably rich as it ups the fueling, not shure on the trac light though mine is fine. make shure you only use optimax or SUL at least ! Link to comment Share on other sites More sharing options...
Supraguy Posted September 11, 2003 Author Share Posted September 11, 2003 Always Optimax with occasional booster. Does this have volatile RAM like the stock ECU? By unplugging it, will it "re-learn" the car settings? Not sure if it will help, but I dont think it could hurt. Link to comment Share on other sites More sharing options...
lovatt Posted September 11, 2003 Share Posted September 11, 2003 yes i think so as mine was all over the place when i first fitted it, it wouldnt even change gear at high revs ! 5mins later it was fine and never missed a beat since Link to comment Share on other sites More sharing options...

Pull, or get someone else to pull, the ABS and TRAC fault codes, after initially clearing them, and straight after the light does its trick.

Supraguy Posted September 12, 2003 Author Share Posted September 12, 2003 Thing is, wouldnt it throw a MIL (!) if there was an ABS or TRAC fault code? Thanks for the reply btw! Link to comment Share on other sites More sharing options...

Thanks for the reply btw! No. I have had several ABS and one TRAC fault that didn't trigger the MIL light. Link to comment Share on other sites More sharing options...

JIC took the car in this week to have a go at this under warranty repairs. I've got to admit, I am impressed with their service though. They gave me a "courtesy car" for the time its in the shop! Its nothing spectacular, but its a manual MKIII Turbo. I was quite shocked to find its performance is nothing close to the MKIV TT. It still goes, but it puts into perspective what a beast the MKIV truely is! Cant wait to get it back, and hopefully without a glitch. Link to comment Share on other sites More sharing options...
