Should I see Spark and Fuel changes with a tune?

When I go through my adjustables while loading a tune, should i see that the spark timing and WOT fuel settings have changed? On both it says zero change. This is on my 89 performance and torque tunes from bamachips.

No, you will not see anything. You will only see changes that you make, like 2% richer, 2% leaner, or whatever spark advance/retard.

However... Don't recommend making changes to those parameters unless you know what you're doing and have a wideband.

I had no intention to. I know better than to adjust something like that when i hae no idea what i'm doing. I only adjusted the rev limiter from 6800 back to 6200 just to be safe.

Gotcha! just making sure. Street tuning is more art than science. Good call on the rev limiter. 6250 would be fine.

Heh, that's the same rev limit Brent puts on his tunes. They want me shifting at 6,300-6,350 rpms. They give it a 6,800 limit so that you don't bump the limiter while getting to the higher shift point. I think I'm going to set mine back down to 6,500 though...my g/f really like to rev the crap out of it when she's driving hard.

Power - Brenspeed Tuner, BBK CAI, Pypes o/r H-pipe,
Suspension - GT500 shocks/struts, GT500 swaybars, GT500 strut brace, FRPP 1.5" K springs,

Looks - Hurst shifter, Misc. brushed aluminium bits, billet shorty antenna, billet hood pins, silver racing stripes

I couldn't get 6250, i could only get 6200 and 6300 so i figured i dont even redline it when i'm hitting it hard so 6200 would be fine for me. i dont know if the xcal 3 only lets you adjust it by 100's and the xcal 2 is different but i cant see 50 rpms making much difference.

Hmmm. Guess I need an SCT refresher. Could have sworn mine was in 50 rpm increments.

I have the xcal 3. Unless you changed i remember you having an xcal 2. SCT may have changed that on the 3.
