Werd, but I have a cracked manifold gasket and that is making it hard to tune my car, I cant see what A/F it is running w/ a def answer. I know it is running phat as hell b/c of all the soot on my rear clip but the wideband says like 11.6-12. So I know it is throwing it off. But I know you are maybe having a slight bit of the same problem but if you IDC's go down, you have some serious problems lol, how is 06Black doing with his? Is he going through the same problems? Maybe you should try asking him or DJT

 

true man. Well think I might be dropping it off soon to do the fuel system on it anyway, so hopefully that will help me get rid of one issue or at least one possible cause

 

Where did you tap to get the oil feed?

 

by the oil pressure sender... tee'd it of

 

Pardon my question since I'm lost, you still drilled the oil pan or it was not necessary?

 

yeah drilled the pan... browse through the thread all the pics are up

 

welllll.... I think she's gonna make it folks.
Just did my morning teardown (after a hard night of drinking lol) and replaced a few gaskets, new wastegate, new dump gasket etc... did a comp test and all looks to be good. Actually got it to now hold an afr across 3rd gear, which is the first time it's ever done it on 3 consecutive pulls. running a little rich right now, but I"ll fine tune it on the dyno sunday. Thank god, this thing has been pissin me off so much lately. And to those going turbo, do not use knock off wastegates. I just put on a new tial 38mm and it's a big difference, turbo spools faster and it actually holds boost all the way to redline now @22.1psi.
More numbers coming Sunday with some new vids so stay tuned folks

 

Good news finally.

 

glad to here that !

 

Awesome Paul, can't wait to see the final results!

 

finally paul u get that beast all dialed in and working now...awesome!!! cant wait to see the dyno numbers...u better send me a txt message when u get ur best numbers.

 

Hopefully with all the little stuff fixed , the pcm behaves better now . We can only hope

 

seems like it's holding ok. Gonna put some miles on it tomorrow and some more datalogging tonight to try and fix one little issue. For some reason once the car goes into PE (I have it delayed to 3500 rpm) it instantly drops to a 10 flat afr then climbs back to 11.1 and holds. Need to lean her out to @11.6 or so, and it should be good to go.
Also thank god it's warm out today, was working in a tee shirt all morning lol. But the car actually has traction to do some pulls. Was smoking em though through 2nd gear was pretty funny the looks people were giving me as I came blasting past them on the highway while spinning the tires lol.

 

hahaha I do the same thing in the rain all the time! Going down the road and people see me fly past them spinning tires with some smoke in there face.

 

pe enrichment rate


::shrugs:: got me, good to see it didn't go blamo

 

yeah I've been messing with that too...
also another wierd thing is dfco... With the car running the way it runs actually smooth and ok... it stays at a 13 something afr when I let off the gas. but if I get it to run with the dfco functioning, the car buck real bad under light load. ANyway, at least it's finally getting ironed out

 

still falls under the stock dfco area? say .10 g/cyl at 36 mph or higher?

i played with that on a past tune and it screwed things up. didn't help anything actually.

 

yeah I'm just gonna leave it alone since the car seems to be running fine.
F'n rain though, I wanted to datalog tonight. Oh well I have the whole day tomorrow to myself to play with the car.
I'll post up some screenshots tomorrow

 

good to see its all working out for ya.

 

Im still a noob at tuning, but what about your MAF tuning? Is that maybe why it has a phat spot in the AFR? Check and see if you got a freq. out of wack at that certain RPM.

 

did that, everything is pretty much spot on. GOnna spend the day tuning the car since I finally have a free day for myself. 1st one in a long time.

 

oh oh send me log!

im just curious really.

i noticed that below 30 degree's my car runs rich while in pe. above 30 degree's it runs commanded. thanks gm. appreciate that....

 

well things didn't go as planned last night. I was tuning for the dyno tomorrow, and the car decided to get all wierd on me again.
HEre's some screen shots of the runs.
2nd gear pull (notice the 143% idc, in 2nd gear)


3rd gear pull, now it's leaning out again, but still no KR. I'm losing my mind with this car, anyone have any pointers.


saturday afternoon bump for some opinions

 

i'm a noob at this stuff, but it looks like the maf went up , and then your idc shot up with it.
i have no idea why it would do that, the second log the maf is high, but the idc didn't go nearly as high?
am i reading this right?

 

I like those iats.
