Are you just trying to change the injector constant? Those are the injector PW thresholds for sync/async injector firings. Not what your looking for, I think.

You need to update the injector constant, which is at $4D88 and is stored as grams/second x 819.2. The injector contant is entered as grams/sec flow into the bin if your using tuner pro, so you will need to convert your PPH injector flow to grams/sec.

yea thats what i was trying to do...

ontop of that i was using some modified OD_v1_02.xdf / i just switched to the OD.xdf looks much more towards my .bin file and pcm...

I got it all worked out, and the truck is totally better than b4. im still kicking myself in the butt from the late start, i should have done this much longer b4!

if you know where i can get a .xdf file with BBC IAC tables and tables for IAT please let me know ASAP! i would like them all in 1 .xdf file.. i have no idea if its such a thing.
