Tune problem

Radman · Oct 12, 2008

I just had a custom tune installed with my turbo and have been experiencing an idle issue. While driving the car the idle tends to not respond to the throttle position when I let off the throttle. For example if I am in third gear at 3500 rpm and shift out of gear into neutral and remove my foot from the throttle, the car will idle at 3500 rpms. If I shift back into gear and stay off the throttle the rpms drop slowly as the car slows down.

It has been back the shop for this issue once and they obviously didn't fix it. Does anyone have any tuning experience I can relay to my tuner when I take the car back in?

not sure there buddy but for what you probably paid them to install it and for the kit itself i would have some arses!! btw what kind of tuner are you using? the tuner itself should def have some sort of parameters for changing things like idle etc.

The car goes in for a live data logging run with SCT next week. They will have the answer I'm sure.

Thanks!

Have you tried reloading your tune? Sometimes hangups and glitches like that may be cured just by doing that.

Also are you doing SCT mail/e-mail tuning? I'm having the hardest luck finding a shop that supports SCT in Houston everyone I know seems to favor Predator down here.

Yikes, that's no good. Let us know what happens.

Why not just get a mail order tune from a reputable tuner?

I did, I went with Bamachips, but as good as Doug is he can't predict all variables such as how crappy gas is here unfortunately, hence why I'm still getting some detonation at anything but an 87 octane tune run with 93 gas.

A car monitored on a dyno under load should at least in theory be better tuned providing the guy doing the tuning knows what he's doing.

I completely know the benefits, you don't need to tell me. I've had quite a few cars dyno tuned. However, why not try another tuner? It's ~$50 for a tune so it's worth a shot. I use Justin at VMP Tuning and have had nothing but amazing results.

I'm kinda low on funds and a new tune isn't on my priority list unfortunately. Plus I want to get it right once not go at it trial and error style.

I do have to give a shot at tuning the car myself. My 93 tune pings past 4K RPM perhaps if I dropped the timing a notch or two that might fix the problem.
