changing the mask id i believe was only for the bpw/tps/spark advance hack for definition file. id be happy to try it but i dont see a file posted..

sorry about that.
That might not be a good plan. See attached screen shot showing the BPW calculations V6 vs. V8 for the posted fair 4 a 262.bin file.
Changing the cylinder number from 6 cylinders to 8 cylinders might or might not have the same effect on the actual BPW?
I think the ECM is going to supply a BPW of 181 for an 8 cylinder engine, that would extremely rich!

I never thought about that, I did see a rich o2 code in his data log it never went below .500 .
that is a good bin for my truck,i would love to have a auto prom or ostrich to tune on the fly.probly around 155-160 bpw would be about a starting point for a 283 v8 with this bin.
I took a look at this bin and seams the tables would be pushing way to much fuel unless your running a ton of advance. what is the fuel pressure you are running with this bin ony? im at 16psi at idle and it drops to 14psi when revved...and thats with the stock spring...it wont go any lower with the adjustable regulator...the injector sizing spreed sheet says the orange injectors flow 61 of fuel... i dont have any others to use so with 16psi of fuel pressure that should give me a bpw around 113 to start with. the spark table matches the headls im using but not the cam so im sure theres some tweeking needed there. the knock counts are low so perhaps i should pull some fuel out and add some advance to my bin. what would ya normaly do first adjust fuel or spark??
I would adjust the blms then add or subtract timming. when you first start your engine watch the o2 voltage and see if it is below .445, in your data log I never seen it go below .500. it my be because it is running rich or the o2 sensor might be going out.i have 12psi fuel that bin is for a v6 I wasn't thinking I thought 283 was closer to 262 than 305.
