Did some logs tonight, set my spark retard limit at 20 so my timing would stay high during the launch. Have my High octane spark advance set at 20 in all cells related to launch, and 15 from 5000-6000 (the rest of the 1/4).

Timing stayed at 19.5 at launch, and 19.5 the rest of the run! Got 3 degrees of KR at 5300rpm and timing didn't drop! Stayed at 19.5 even with 3 degrees KR. So KR still shows up but doesn't do anything to timing.

Dropped spark retard limit to 15.
Timing stayed at 14.5 at launch, and 14.5 the rest of the run. No KR.

Raised timing to 15.5 in the high octane table.
Timing at 14.5 at launch, and 15.0 the rest of the run. KR spiked to 1.7 at 5300rpm, timing only dropped to 14.5!

So, it looks like spark retard limit does effect the amount of timing KR can pull. And, the base timing on a run if your high octane timing is set lower than the spark retard limit.

 

I want to know where the retard is coming from that I couldn't find. I was/am getting retard at part throttle acceleration around 50-60% throttle when it kicks down to 3rd and unlocks the TCC. It was dropping down to as little as 2 and would hang around 4-6. I raised the Limit table up to 15 and now it only drops to 15. My WOT runs still stay where they should according to the HO timing table.

 

i dont think knock retard will show up on the timing that is shown on autotap unless it is persistant and pushes into some kind of knock learn.

i always thought you had to take the timing that was shown and deduct the knock retard to get the actual timing.

are you saying that if you normaly see 25deg at WOT then get 5deg of KR, you will at that point see 20deg(shown on atap) at WOT untill it tapers off? just trying to understand if i am not seeing this corectly.

 

Yeah, on logs I've done without spark retard limit set high, you can watch timing drop the exact amount that the KR commands it to, at the same time you see it kick in. Then as the KR decays, timing goes back up to your ho spark table set point.

At least this is how it works with EASE. You see the timing your engine sees at any given point.

 

I want to know where its coming from too! That way, we wouldn't have to set the retard limit so high. I'll bet its another x-factor table that hasn't shown up yet in edit.

Where is your timing set at for your wot runs? Above 15?

 

19* starting at about 3000 and it gets up to 22 I think by the time I shift. Still no KR at all, I just don't want to take it any higher until I feel I know what I'm doing with EDIT.

 

I can't seem to squeeze more than 16 degrees out of mine. Must be the 91 octane premium gas here.

 

We have 93 here ... I'm only running 7psi too. My IAT's get up there pretty good, but I still don't see any KR so I guess it's all good.

Have you run yours at the track ... if so what kind of times are you running? If I remember right .... aren't you running something like 15psi or something crazy like that?

 

I'm running 11psi, but only seeing 54 lb/min max because of the crazy 5000+ altitude i'm at.

My best track time is 14.8 at 92. That was with a slipping trans, intake blowing off, and a TT3000.

Haven't run it at the track since the FLP level4, new intake tube, and SS3800. I have g-teched it (old style g-tech) times range from 13.5 at 102 to 14.06 at 98. The crazy 4wd launch seems to screw up the g-techs times. Our track opens in april.

 

Man ... that sucks that the altitude does that much to the air. I saw a max of 57 something on the stock MAF table. That's spinning it up to 6200 with 7psi though. I am only about 200 above sea level though.
