[Ls1_Rulz]

i think it's a little rich at WOT ?? what do think ?

anyone can give me suggestions about tune ...

best time 12.06 1/4 118MPH

anyone !!! i know alot of pro tuner here !!!

Ok, a very basic review of your log and tune file indicates your spark data is set very aggressive, as indicated in log results from KR. Your A/F, in my opinion, is commanded too rich low end in the PE VS RPM. I have no issues with 12.9:1 in PE table, but thats not what you are seeing real time. More like close to 14:1

SPARK:
1. KR is too high. Setup a MAP of
DATA=KNOCK RETARD
X = DYNCYLAIR_DMA (Air Flow gm/cyl-speed density)
Y = RPM

There were a few points where you had as much as 13 deg of spark taken out. Reduce the spark and smooth or add race gas. Even if you add race gas, the power still might not be there.

2. A/F at WOT is TOO LEAN all the way up from idle. Setup a MAP of
DATA=AFR_LC11
X=MAP
Y=RPM

At max torque point you were almost 15:1 A/F. Review the map in the
95-100kpa range and all RPMs

In my opinion, you should consider lowering the spark to stock, then do a VE tune first. If your injectors were changed, which I don't think they were from looking at your data, adj those first.

If you don't know how to make the maps, play w/the software until you do.

BTW, are you running a stock cam? Nevermind, I see your KPA is 60 at idle.

It looks lean for my liking (showing 13.4:1 average)and you need to carry out an auto VE as you commanded fuel and actual fuel are a way off.

Look into lowering your intake air temps before your run as they a very high, possibly causing the missing timing as your spark map has 28 and you are only getting 25, log your EST spark pids to find out.

You could speed up your KR decay rate to help get back to normal timing after knock retard and not effect the whole run.

yea your commanded vs actual isnt even close....youre saying youre rich at WOT...not really but you are commanding even richer....and whats the deal with your IAT temps being in the 150s....you live in the desert?

[Kurtomac]

and you were gettin KR the whole time during your burnout in the 3rd log you posted

I agree... you need to dial in the VE table... one of the reasons is that this will make DYNCYLAIR_DMA reflect the true actual cylinder airmass which will allow you to precisely adjust your spark table (since DYNCYLAIR_DMA indexes into B5913/B5914)... DYNCYLAIR_DMA shows about 0.76g (actually, less) which is what a stock LS1 shows, you obviously have mods, you probably should show about 0.80g... VE table needs to be dialed in...

The other reason is that your CFOL/PE AFR's will show up on the wideband... what you set is what you get.

Cheers,

ooooooh thankx

great info thanx again >>

Knock Retard Recovery Rate - I usually set it somewhere between .05 and .10. Better troubleshoot the actual problem though as this is just a 'band-aid' so to speak.

ok sorry about this question ( i'm still new )

but


what should i do first ?? now i think i'll start from stock tune 1998 camaro
this what i'll do step by step

(autoVe) next > (find and adj. the best timing) next > (RAFNG process)

anything else ?
