I found at holdencrazy a 2002 with the same bolt-on's, Super Sucker Ram Air, SLP Lid, SLP Bellow, Pacesetter LT Headers, Pacesetter ORYP, Magnaflow Exhaust, 3.73 Gears, 3200 Midwest Converter, !AIR, Rear O2 Codes.
With both files open I copied the following

Is there anything else I should be changing in the tune?

[mvvette97]

Did you make a backup copy of the stock tune? If so let me know and I can work on it for ya. I tuned my sisters 98 z just a while back. It really helped it alot.

[pdasterly]

I started with a fresh tune for a 98 z28, after my hypertech. I just downloaded it from holdencrazy and opened both the stock tun (http://holdencrazy.com/EFILive/TuneFileRepository/Stock/Chevrolet/1998%20Chevrolet%20Camaro%20Coupe%20Automatic%20LS 1%205.7%20Litre%20(PCM%2019980100).tun)e and 2002 modified tune (http://holdencrazy.com/EFILive/TuneFileRepository/Modified/Chevrolet/00000025.tun) and made those changes. thanks for looking

[mvvette97]

If you want I can make a tune for you and you can try it to see if ya like it. I assume you have an automatic with 3.23 gears?

[pdasterly]

I have an automatic with 3.42 gears, please cause i'm new to this still learning the lingo

[mvvette97]

I have an automatic with 3.42 gears, please cause i'm new to this still learning the lingo
ok, I'll get one put togethor this evening for ya

[pdasterly]

my tire size is 255\30ZR22 thanks again. anymore info you need?
I have a short idle run in the scan program

[mvvette97]

ok, I'll see if I can get it here after a bit. You will have to log it after ya flash the tune in to see if ya have any spark knock.

[mvvette97]

Here i the tune from my sisters 98 z28. I changed the tire size and gear ratio for your car. Flash it in and take it for a drive

Just had a thought, if you have the stock thermostat you will problaby need to put the stock fan settings back in or the fans may run all the time

[ItzNota]

So.....did it work??
Curious to see how things went.

he must be on the test drive still or he got lost..:hihi:

[pdasterly]

The tune u sent me ve table and high spark maps are stock, what did u modify? You can compare your tune with the stock tune by File>load alt calibration data(ctrl-F11), then press (ctrl-12) for the data to be displayed.

[mvvette97]

I don't think I changed the timing at all because every time I done anything with that I was getting KR with her car. Don't know if it's true but I had a tuner tell me that the 98s have a pretty aggressive timing settings from the factory and don't really need much changing with just boltons. In my case it was true. As far as fueling I just copied what the tuner did and it worked fine on her car. I noticed the major changes was with the auto tranny settings.

[pdasterly]

I copied the ve table from a modified bolton camaro from holdencrazy (http://holdencrazy.com/EFILive/TuneFileRepository/Modified/Chevrolet/00000025.tun). I ran the scan tool and I have no knock, im using 91 gas california
