I am getting further into chip burning because my tuner has been unable to get my Suburban tuned close. The last chip was too lean the one before that too rich, idle issues etc. I have been messing with this truck for almost 2 years now. I have done alot of reading here and at Tuner Pro to get up to speed. I have been burning chips with a Moates burner for some time now, but I guess I will have to tune it myself. I have been using Datamaster for logging but may try Tuner Pro so the terminology is more like what is used in this forum. I have found several BIN's that are supposed to be correct. I have been using the compare feature in TunerPro to look between the stock BIN's and what I have been burning to get a feel for where I am at. I went to Moates to download the stock BIN and under 16197427 I assume OD there are alot of options which one is correct? On top of my ECM there is the 16197427 BJYL. I did not see a BJYL bin listed in the OD or OE folders. Would I use the 95 full size van BIN's or is there a better base BIN to compare to. I have a 95 Suburban 350ci, 1500, 2wd, 4L60E ( from memory engine:bored TBI 50mm with 454 inj. / Elebrock centerbolt heads / 20 psi fuel pressure / comp cams cam / headers / bored .060 over / roller cam/ open element). I know the stock BIN will be along way off but I may be able to use the spark tables as a baseline. At this point I want to find the best or most stock point of reference to compare the BIN's I have against.
Thanks, Charles

 

I did a search for BJYL and found this and several others...

Not sure why Moates does not list it?

 

Thanks Ronny,
I suspected the four letter code was my PROM BIN but when I didn't find it on Moates I was unsure. I was trying to loacte a BIN from somewhere that I could trust (ie not hacked). I had problems downloading the zip files from the other thread until I got Firefox. I did find a stock BIN from another thread. Dimented made a comment in the other thread about the .xdf not showing all of the apsects of the program. Did I understand that correctly?
Thanks, Charles
