Disconnect MAF ?
Hey guys,
I'm a noobie and it's been 3 yrs since I tuned my TA. Don't use it ya loose it ?
I'm trying to tune my 03 Silverado and it just seems to run lean no matter what I do.
I've set the MAF freq to 0, disabled the STFT and LTFT to try and get a base VE/AFR table. Yet no matter what I do it seems to run lean.
Does the MAF need to be out of the loop ?
Attached is the current tune and a short log. It seems to me the VE is very high, but I tried upping the values to get it running.
It does run with everything enabled after I upped the MAF values a little.
It's a forged LS1 with a 224/228 115 LSA CAM 035 ported heads and a FAST 90 with a 87mm TB and the X link adapter.
ARH 1 7/8 headers into 2 3" magnaflows. CAI also.
Please check out the tune and let me know what you think.
Thanks for any help.

I finally figured it out.
I did not have the MAF fail to 0 therefore it was still looking for it.
Though afterwards, code 1514 would pop up and then I could do nodda.
I upped the 1514 fail value to the max so I can drive the darn thing.
VE is pretty close but needs more log time.
