Could use some help here. P59, DBW, mild cam 231/242 (advertised 280/292) 3600 stall, truck intake with 50# 12613412 injectors. Back story for those whom haven?t seen my previous post. This truck is running on a tune that was done 3 years ago and roughly 15k miles. Now that I have more time to get back into tuning, I started datalogging the vehicle and noticed it is very rich, and timing looks like California after an earthquake. I have done datalogging with and without a wideband, using STFTs and without. Currently I have the MAF failed, disabled LTFT, disabled DFCO, disabled COT, set EQ ratio to 1.0, copied hihg octane to low octane, and disabled PE.
I have an apprx 10 mile ?course? that enters a highway, can get up to 75 mph, then exits to regular surface streets back to start.
When datalogging, I am showing lean. So I added 10% to the VE table. I have run this route 4 times today. Engine is above 170 degrees, I start datalogging once I start driving, and the wideband is fully heated up as to not have any odd variables. Once I complete the ?course? I take the data copy, and past special, multiply by half %.
For example, if you look at the axi/row at 55kpa/2400 rpms there is virtually no change on 4 of the charts. And on the 5th I cant explain that one.
I have watched many videos, and have done research through the forums, and either I am making a blatant mistake, I?m positive I?m doing this correct, but why am I not getting the numbers to change, or the inconsistencies?
My previous post has a copy of my tune, and I was told its too rich, injector data was wrong, and a few other things. Those suggestions and comments were implemented, and I really could use an extra set of eyes as I have to be missing something.
Sorry for the long post, I wanted to get as much information as to not having people guessing at things that have been done.
Thank you in advance..
