i know this really isn't for forum for it but i trust SAU more then commo forums.

looking for a tuner that can adjust AFRs and remove a crappy "powerchip" from a VN commodore. it's a wagon and useful for moving stuff but the fuel efficiency is ridiculously poor, something must be off and i suspect the "powerchip" has something to do with it. considering it's old, was installed back in the early 90s.

any tuners that would be willing to take a look at it? how much ya think it ll cost?

the ecu doesn't wear out, ie it's a static tune once set

check the 02 sensor, its probably the factory 02 sensor which is like 200,000km old

they dont last forever and when dead the ECU will waste fuel

ecu doesn't wear but the engine does. o2 sensor has been replaced many times.

it's been running so rich, when i took the exhaust off the cat was burnt out, completely. still sure it's the cheap power chip.

Why not just go to the wreckers and get a stock ecu without the power chip and just replace it. Also "Greenfoam" on the Just Commodores forum would definetly be able to help with this problem as he does powerchips for many of the members on there.

    • Can u check this way it works for power supply?
    • These coils draw 10amps that what i read online
    • I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly. 
    • That worked out PERFECTLY! Thank you big time to JJ. He was able to swap me his stock diff. He drove all the way to me as well. Killer! Removal & install was pretty straightforward. The diff itself is HEAVY. So that’s a 2 man job.  Man does the car drive nice now! Couldn’t have worked out any better 👌
