I'm having problems with my car (misfiring), have done the plugs. But I hink it will either be the coil packs or soemthing with the air/fuel. The engine is a RB25 and is running a Haltech E6K.

I was thinking of taking it to APC because I have heard they have the good equipment for Haltech. But what sort of price would I be looking at roughly for a good tune??

Should they be able to fix my misfire??

Any other suggestions?

I got quoted to tune my 32 gtst, $400, i also back a miss firing problem, sound like a wrx, i spoke to my mechanic and he said definetly a coil pack has died,

so mines running on 5cylinders, and sluggish as all hell off the line, i can rev it too 5 drop the clutch and it almsot drouns itself

I *had* the same problem up untill yesterday, have a look for the thread i started in forced induction performance and read that for a checklist of things you can do at home rather then spending $'s at a workshop. I had a bad earth which cost me $9 to fix and a dead coil which cost me $35, try some of the things in that thread to diognose the problem, then if all else fails, go to a mechanic.

YOU MIGHT NOT HAVE TO GET IT DYNO'D TO FIND OUT THE PROBLEM!!!

i had similar dramas with my 32 and had it dynod at couple of different places and both times miss diagnosed and cost me alot of time and money.

A mate then told me of EFI diagnostic and repair centre at capalaba and he hooked it up and told me what was wrong with it in an hour or so and cost 1/10th the amount of cash the others were charging.

just cause a place has a dyno doesn't mean they have any idea

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
