well i finally got it started

[bonnieclyde100]

i finally got my truck started today but it didnt run so good which is probably exspected for the first start up. i have a 16196395 pcm running an $OD bin file BJYL xdf advanced $OD TP5 v251.xdf adx file a217 $OD TP5 v250.adx . im going to try to upload my first datalog and i wonder if someone could take a look and point me in the right direction. i do have a couple of questions i cant seem to find where you adjust the desired idle because my came runs a 224 duration @ 50 and doesnt like to idle that low .also do i need to disable the manifold air temp it is showing -40.0 .i dont think my tbi even has one on it and i am afraid it could be affecting it. any help would be appreciated?

Idle speed tables

MAT needs to be unchecked.

mat is not checked

the rpm numbers in those tables are they actual rpm or are they numbers only the computer recognizes ? if i want my idle to be 100 rpm higher do i raise most of the rpm numbers by 100 ?

Idle speed tables

numbers in those tables are the idle speed the ecm is targeting. I would try adding 100 rpm everywhere for starters. You'll need to adjust spark tables too in order for it to idle. In both the open and closed throttle spark tables, set the timing to 25 degrees in all cells 1,000 rpm and below. You'll adjust the high map cells down later after you see where it idles. With that cam it will probably be around 60-70 kpa at a 775 rpm idle.

I'm surprised the blm is at 165 (full rich) when you're holding it at 1,300 rpm and 50 kpa. I would expect the BJYL tune to be rich in that area with your big cam. Are you sure you have 61 lb/hr injectors? is fuel pressure at least 14 psi?

i will have to check injectors tomarrow and dont know about the pressure. i rebuilt the regulator with a stock kit and the injectors were in the tbi when i got it at the junk yard

i have the 5235206 61lb/hr injectors as far a pressure i ordered a gauge and adapter fitting i should get early next week .i also made my regulator adjustable so i can set the pressure. what pressure do you recogmend for my application ?

well i found out the pcm either burned out on first run or was all ready burned out when i used it. i dont know what my pressure was the first run but after i made the regulator adjustable i set it at 13lbs .well that was to much it was burning so fat it would hardley run so i nocked it down to 12lbs and now it will run better but looking at the numbers i think it is still running rich. here is a data file check it out and let me know what you think.

Yes, here are the numbers i'm using in my .bin
