I tuned my supercharged '99 Regal GS after doing a lot of work to it. I swore I'd never do it again. But then you run into things like this and remember why you do everything yourself.

It's just that I've put so much blood, sweat, tears, money, and time into this. And now I'm scared to death it may be damaged.

Kbracing96 sells EFI for a good price and can help you too. Maybe Justin would be willing to send you an unlocked tune so you could bounce logs back and forth with him and make adjustments like the injectors yourself which is easy along with your trans shift problem.

I doubt you hurt your engine since you only put one WOT run on it unless its REALLY lean and a decent amount of spark.

Oh, it never saw WOT, except for a split second for the crank relearn. It probably never saw any more than 1/2 throttle when driving it.

I just remembered I have this old Palm with LS1M logging software. I'm going to put new batteries in it and hook it up.

BTW, I really appreciate your feedback. Otherwise, I'm in a cave here fretting and stewing myself to death.

I pulled them all. They all look identical. This was just after a bucking episode, possible causing the black.










Here's are the O2 sensors as I pulled them.




This is after I heated them up with a torch.

Here's a vid of what it's doing when you first start it. When hot, it doesn't come out of it this fast. This is what started on the interstate when I got on it about 1/2 throttle and kicked it down. You can hear it cutting out and back firing when I give it a little throttle.

Alrighty, I'll let you know what I think:

#1) Your motor is fine
#2) The tune is no good
#3) Your o2 sensors may not be giving proper readings due to low heat

Buy EFI live V1 (no need for v2) and I'll get you set up. Your engine setup is very similar to mine.

I was just looking at EFI Live V1 and V2. I only think I need V1 as well. Where's the best place to buy it, and what does it cost? Can I buy it used?
