I posted this on the AEM forums but it's a little slow over there.

Any of you guys want to take a look at my log and provide feedback? I feel like the car is getting much faster than before from adding timing at the current boost level, though it seems to have leveled off in power. Do I have more headroom or should I back it off for safety at this point? The main focus has been adding timing in the midrange to help spool up the turbo faster. Are these knock voltages acceptable? I don't hear any audible pinging. I have also been logging 60-90mph times to confirm whether each tune is faster, this particular run was slightly slower than the previous day which had less timing added but was cooler ambient air temp.

I have the following mods:

V.1.19
ATP 3037 turbo kit
Revolver cams -2 -4 I/E
AMS intake manifold
turbo XS FMIC
720cc injectors/perrin fuel rail
catch can
custom IC piping
removed balance shafts
rod bolts/head studs
probably forgeting other stuff.

TIA

 

I could go compare it to another map that has the similar mods (almost identical except for the intake) and see how it's like tonight...

 

did you change the fuel map?

the other guy was running 277 at the top of engine load around 5000rpm... to mid, which is around 200 ~240...

had more fuel added on the knock fuel add max and more on knock decrease fuel...

looks like you're re-circulating?

what's your afr look alike?

 

AFR typically hits around 11-11.2 on the top end. I'm running a tial BOV on my upper IC pipe and a 4" intake straight to the turbo. I had to play with the fueling quite a bit when going with the AMS intake manifold, it's still not perfect but a lot better than before. Thanks for the replys.

 

From what I saw of the logs, nothing looked abnormal. No large spikes in knock volts. Afr's looked good. If you want to get more samples for datalogging, look into internally logging to the EMS box. You can log up to 250 samples a second where the laptop I believe only logs somewhere in the range of 20 samples a second.

 

It's a bad habit of just using the laptop since it's much easier to record just the sections I want. But you are right, I should be using the internal logging. Thanks for the reply.

 

It's not a must to use the internal log, but when logging knock volts thru the laptop as well as thru the internal logs at a higher sampling rate, there were many things the internal logger picked up the laptop didn't.

 

Looks pretty good. Have you tried to run alittle more timing to see if the knock changes alittle? I run few more degrees of timing across at the same boost but i am on 93 and 94 gas. Your callibration for the Knock seems high at 3 volts for that much power and your motor doesnt seem to have that much noise. I would also rescale your maps so that they only go to like 10k or 10.5K so that you have more points to smooth everything, but be prepared to reset all the values. Damn that thing is laggy 6K what gear is this?

 

I definitely think more fuel up top.

 

What AFR's do you guys normally shoot for? I've been aiming for right around 11-11.2 up top. I won't be able to touch my car for at least another month, I'll try rescaling the rpm values and maybe bring the knock table down slightly. Anyone care to share their knock table for comparison? I may try adding more timing in the bottom and midrange, but adding more up top seems to have leveled off in power, don't really know without a dyno. Perhaps another pound of boost? I get a little worried running much more than 24 psi on 92 octane.


Tt

 

Also what do you guys thinl about going with a 0/-2 I/E instead of -2/-4 to get the turbo to spool a little quicker for the cam gear settings?

 

my knock table, was setup to go way up at 3 volts at 3500 rpm and straightline until the 10,000 RPM.

Of course, I was like wtf? So I went back and straightened it out from .5 volt at beginning going 45 degrees up to 3 volts at 7000 rpm, and coming straight down to 0 volts after 8000 rpm.

 

The log looks fine. Your making decent power.. just shy of my car at 23psi on the 35r. I run mine MUCH leaner... 11.5-11.7

Your timing is very similair to mine.
