88TII, Haltech E6k, just got the car back from a years worth of mods in Dallas. Chris Ott tuned it out great in Dallas but I live at around 3300 feet above sea level. The only thing I've done since I got the car back last week was install a vent cover over the passenger headlamp. I run a 62-1 turbonetics and the filter is right there below that vent.

Issue: WHen the car is cold the idle is rough and you have to keep on the gas till it warms up. Once warm it idles pretty good but still a little rough. SHould I goto the cold map and adjust the fuel since I'm up in elevation about 2000 feet from where it was tuned? Will the vented cover change the a/f? What map and what should I do first? try leaning it a bit or richening it abit for a higher elevation?

Also my knocksensor at 16psi high rpms under full boost activates and the guage lights up about 2 or 3 bulbs which I think is about a 2 degree retard on the timing.

I am running Sunoco 110 race fuel exclusively in it.

This is a good starting point I think. If you need any other info please post up and I will reply.

I'd like to know where to start correcting for altitude and the ventcover.

Thank You!

 

can you post your map?

 

left my patch cable in Dallas should have it back via usps on monday. Will post it here soon as I get the cable in.
