I got car code and played with it on the way home from work today. Let me run some data by you guys who know because I don't know jack about this <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />
At WOT
spark was 12.5-14
O2s were right on .90
I don't see any KR on this software, how does this look to you guys? Is there anything else I need to be looking at like fuel trim?
One thing I noticed is its shifting right at 5000rpm <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> I guess I need edit because magnacharger must be real conservative with the superchips tuner parameters, shifting at 5grand.

if it's like ed wright's tuning, you won't be able to modify your program. from what i have heard, he "locks" the pcm so you have to come back to him. the numbers you do have look ok, need more parameters to make a good determination though. how about your ltrims?

 

my $.02...with a blower that timing isn't too bad, you might be able to squeese a couple more deg out of it but 14 is all i get. if it is like atap you can't really count on the rpm it is showing, atap is too slow. i shift right at 5800 but atap shows 5000-5600 tops. my a/f ratio is 11-1 and my o2's show .87-.90 but i am told the stock 02's vary by vehicle and temp alot.

you need to look at knock retard and ltrims would be nice too.

 

Your stock timing should be in the low 20s from the factory. You could be having KR and thats lowering your knock. Or, you are flowing much more air than your PCM planned on and your are in cells of your timing table that have low timing from the factory. That happened to me.

In the PCM, timing is given out by RPM and by MAF flow. This is in a spreadsheet like table where it looks at your RPM and reads your MAF then adds the right ammount of timing. If you are flowing a lot more air through your MAF (which is highly possible), then the stock PCM's timing table will not be accurate anymore.

 

Thanks for the info guys. This software seems to be a scaled down atap. I don't see any option to veiw knock retard but I am still playing with it, the spark advance is shown as total advance for #1 cyl. It does show short and longterm fuel trim. S1 is 0.0, L1 1.6, S2 0.0 and L2 0.8 not too sure what that indicates so I have some learning to do. MAF shows 42.6 #/min. This is all at WOT right before shift.
Parish8, your right I think the update rate is to slow for the rpm, when I look at the tach during shifts is looks more like 5500 to me.

Forgot to say that this is the superchips tuning that came with the magnacharger kit. Not stock programming.
