I haven't posted for awhile. So here goes. They say that tuning is addictive. Their absolutely right. Must have burned 200 chips and its still not what I would consider a good tune. There is so much to learn. After about a year I have just scratched the surface. I can't seem to get software (tuner pro) to agree with wide band o2 sensor. Going to keep reading and learning and burning chips untill I get it right. Because its habit forming. strokerutah

I envy you. Hopefully soon I will get the Vert mechanically stable enough to just tune and the coupe will still be some time off. Once I am able to start tuning on the Vert are you open to questions?

Sure, I will help you get started. If needed you can drop by. We can go over the steps to make a bin file. Then burn it to a eprom.

Thanks. Going to pick up the cable to link laptop to car this next week I hope. Hopefully be for long I will have fixed everything and will be working towards tuning. The week is the Certain new top thanks to my insurance company and some idiot breaking into it.

200 chips? What are you trying to do? Get every last 0.001 HP out of that thing.
Your tune isn't limiting your power. It's your intake manifold.
Could you define what "getting it right" means? To me it means passing inspection, not fouling plugs, getting average gas mileage, and then not being able to get any more power out of it after dyno tuning. Didn't you have it "right" 2 years ago?

Just because A/F ratio was about right under full throttle does not make it right. Two years ago idle was lean. Spark table was wrong. Cranking to start was long. Emissions were over 5 times the limit. I don't call that getting it right. I may have exaggerated on the number of chips I burned. It was closer to one hundred. I have read on corvette forums that a number of people have burned 2 hundred chips for one car. Thats what my topic (tuning is addicting) was about. If you have the time and want to make 16k bin files, it doesn't cost anything.

Yeah, it sounds like even with your small LSA that you were running dirty. I could always get mine to pass if it was lean. Thing was that if it's misfiring it will say it's lean but really be rich. If your HCs are high but the WB is saying it's lean, that's probably the case.
I spent a lot of time figuring that one out. Tuning for me was addicting, and then it quickly became frustrating.
