btw my cam doesn't have the posted lift in the signature .585 intake, .589 exhaust, not that it matters

whats the classic mistakes? lol I'm afraid to ask...

Check out this file, you can run it if you like. It won't be spot on but it will
be a good base tune that either your new tuner or yourself can work from.
Most of those basic issues have been corrected, max power might be down
a few but driveability should be MUCH improved.

I've been reading through Shawn's posts and it's starting to come back, off to give it a try...

Yep, those spark tables are hacked big time. The tune L31Sleeper posted is much better, although I bet you'll be able to dial it in better when you're tuning it Rich.

Check out Shawn's Calc.VET method. As he said, an afternoon and your VE/MAF tables will be dead on. Make sure you log the appropriate PIDs when doing it, Ive got a few logs that are worthless because I forgot some crucial PIDs. You can also use those logs to adjust the spark tables, open up the Knock Reduction MAP and then you can copy/subtract those from the Scan tool over to your spark maps.

Thanks Erik..

Ray, I must say nice HP/TQ on your dyno run. AFR's were a little 'off', but stout combo.

I have not totally looked over Sleeper's Tune..but looking at your original..a few comments.

1. Looks like a Speed Density, closed-loop Tune, with MAF & LTFT's disabled.
2. High-Low Octane Spark copied (necessary in a non-COS SD Tune).
3. Throttle Cracker zeroed out (..thats mainly preference).
4. Some Idle tricks (PE Mode at Idle).

A couple nice things about having your MAF-enabled is that you can have differing High-Low Octane Spark Maps. So if you get any KR, your PCM can adjust to the 'right' spark. Personally I like LTFT's enabled..essentially they are just STFT's averaged over time.

I think it was a nice dyno run..please check out the CALC.VET. Your actual VE Table looks pretty good, but you might benefit from a nice MAF/SD hybrid Tune..(aka re-enabling the MAF). Your stock MAF should be fine, especially with your increased injector flow.

Let us know..

[ScarabEpic22]

Oh yea thats right, with no 97-98 COS running SD means you only have the low octane spark table and no adaptive spark. Right there is an incentive to upgrade to a 99-02 PCM and through COS3 or COS5 at it. Don't they default to the Backup VE table too?

As Shawn said, your setup could use the MAF just fine. Then you'd get adaptive spark (and maybe the Main VE table) back as well. Thats assuming you have it and it fits into your intake setup.

[L31Sleeper]

Here ya go MAF and LTFT enabled, sorry I over looked that I normally don't disable those
unless in a AutoVE tune which is only for tuning purposes.

[NASABlue]

Thank you gentlemen!
I'll get a log posted back up in short time.

[L31Sleeper]

Any updates?

The log isn't that long, but I'm trying to make sure I have the pids set up correctly. I'm getting an error message thatg not all of the selected pids have readings or something to that effect.
