Two thumbs and a big toe up for PCMforless!
Got my computer back today after the LT4 conversion, and dang if it doesn't feel like a stock car, except for the amazing POWER when I punch it. Shifts real hard and quick, and has great throttle response. My 0-60 time feels like 4.5 seconds on the butt-o-meter.
Anyway, just wanted to say thanks to Bryan!

Good to know your happy with your tune. I just sent my specs on my car to PCMFORLESS and am waiting for the tune by e-mail. I thought I'd give them a try before going to wideband O2 dyno and spending hundreds of $. I f they can tune my motor for $50.00 I'll be stoked.

Sounds like you got money in that motor, I'd go for the wideband O2 tune.

On the dyno his a/f ratio was almost 15:1.
By putting some fuel back in the car and taking some of the excessive timing out of the program he is making about 15 more hp and the curve is much better.
Idle and part throttle are also much improved after some tinkering.

Yup, too much timing and not enough fuel.
My tuner said it was "dangerously" lean.

Only gained 6 hp with the dyno tune because the first was so darn good.
dangerously lean? Do you have a FPReg, bad injectors, or old dirty **** filter in your list of 'ect mods' by chance?
nobodys perfect, so it's definitly quite possible he did screw up your tune. funny how you got exactly 350 rwhp with a cc306, and I did the same with a 218/224. Maybe yours 'sounds better', but i bet mine has better manners. You have a graph of that by chance?
I think you and dan k are the minority, but thats cool, all voices must be heard in the democracy of cz28

I've seen a hotcam file from another member of this board and his car made great power and he said drivability was nearly stock. The file on the car I mentioned also made good power and does drive like stock. And those 2 files were quite different.
I think some of you would be suprised at how little needs to be done to make a hotcam car run "good"...and how much needs to be done to get it to run right.
Some of you have had great luck getting a mail order tune, while the 2 cars I've had on the dyno this summer with mail order stuff were both very lean and had too much timing. While I might be of the minority, others here should hear my experience. That's all.

Off the subject here but what program are you using to view the Lt1 files in. I'm trying to learn the microcontroll (motorola 68HC11 that is the controller in the 1995 z-28)its for a school project and so I can write my own programs. I have not found a decompiler yet that will let me look at the program in any programing language I know (C, Visual C, Turbo Pascal, Visual Basic). So what are you using to loo at these files.

Another thumbs up for PCMforless. He tuned my car for the 306 and the *heads* I am running. Among other mods. I think the car runs pretty smooth, and my scanmaster shows good things while driving, and at idle.
Sure, it was a *mail order* tune, BUT darn good, and very cheap w/ excellent customer service! Very affordable! Who wants to spend $400+ on a dyno tune? I can understand if you have a lot of bones in the motor, but the majority of us here-don't.
Keep up the good work Bryan

My setup made 350rwhp with a very conservative tune for the summer here(112* daily) and 91 octane gas. He also only revved to 5600 rpm on the dyno because the motor was new.
The tuner said there is another 25rwhp with a more aggressive tune and quite a bit more between 5600rpm and 6600rpm.
In other words, with no timing, 91 octane, and 110* heat, it made 350hp.
Oh, and thats stopping at 1000rpm shy of "redline".
And I got 349.8rwhp.
