2 bar SD turbo start-up tune issues

[akdg1987]

hello,

this is my first turbo build, and i was trying to get a start up tune so it would idle, but i am not having any luck; AFR goes very lean and it dies (greater than 17 on AEM UEGO W/B). i checked for possible vacuum leaks at the intake ports but didn't find any. Ive compared my injector data to others in the repository and mine seem pretty close with them.

hoping someone could take a look and chime in. current tune is attached below.

Specs:
5.3 with "317" heads
ls6 cam
ls1 intake
Siemens deka 60 #injectors
1:1 FPR at 40 lbs of pressure
8 an feed and 6 an return
bosch 044 inline pump.
76 MM turbocharger

thanks DG.

Start with the PO101,102,103 set to 0-Mill on first ERRoR. will look a the tune in a little bit.

Does it make a difference if i have them all set to 3 - No error reported? Thank You

Yes. The ECM has to see the MAF fail for SD tune only. Here are few thing you need to disable as well. With out a log,I have you set your idle up.

Also put the correct idle value in the first cell of the MAF curve, it will still use that one to try and start til MAF fails.

Sorry if i forgot to include that i have removed the MAF completely and im only running a Syclone/Typhoon IAT sensor.

But i Appreciate the input and will hopefully get to flash this new calibration tonight.

okay thanks, im guessing the maf DTC settings is what was affecting it, starts up great and idles a bit rich but it idles!
