I do have ford data converted to gm. I can check tonight and see what i have. Quit listening to everybody, make a plan, stick with that plan. Dont listen to people working with shit parts and unknown mystery data.

You need to eliminate as many variables as possible and take it one step at a time, at this point the airflow models should be the only variable, PCM needs to accurately know how much fuel it is supplying so accurate airflow models can be derived, volumetric efficiency/MAF, this affects almost every calculation made be the PCM. If the VE is off because of bad injector data, everything down the line is skewed, you're cylinder airmass ends up incorrect, throws off the spark table, throws off the torque calculations which is used for transmission shift calculations, protection modes, etc...
Here is your correct data translated from calibrated success.
a thanks for this info. my truck is doing alot better.. im slow at this stuff but learning it. i really like the hptuners whys, its a learning curve for sure.Originally Posted by 04silverado6.0

Make sure you get the correct map data in. I would go back with a gm sensor that is common.
its a 3 bar map, map data is from a reliable source. its right for 3 bar. my afr is match to the tee. i had bought the map when i bought the intake. my map is a ac delco has a bunch numbers. its red, 0 261 230 185 this whats on the map its self. like i said its red.

That is 100% incorrect for that map. Here is the correct values.
312.50
-11.25
Here is the stock zr1 file that uses that map.
ok thanks man

ok thanks man. you have been a huge help. truck is running so much better. the first time i had this pcm touched for the set up i have i had pcmforless do all my tuning. ans it was fine for long time, i had changed intakes and couldnt get the injectors to seal up right. i figured what the heak buy the mpvi3 and see what its about, its lil hard, but with help in these forums from you guys its been a learning curve for sure. again thanks

Should be ready for some ve tuning.
my afr gauge is matching the commanded setting. i was told if that happens that the ve is pretty much on point. or is this wrong info? seems like all the info i had gotten before was not right.

i could log a scan or two with these changes that you helped me with and let you see the data. might be a few days till i can get it to you. if you want. i appreciate the help. i usetoo deal with the carburetor cars. the turn of this or turn of distributor . it was easier back then. i do like these pcm cars and trucks take some learning for sure. i owned few camaros in my day. i had a 1969 it was a nice car i owned that one for ten years and then sold it like a dummy. thought id get another, i hadf a 1977. then i had a 1986, and a 1994.. ive always wanted this new type the 5th gen ones . i will be trying here in a few months to get one, alot of things are lining up for me to go out and find her. im trying to learn this stuff so when i do get one ill know what to do. some what that is

Post a log.
2003.gmc.seirra.5.7.4l80e.862.small.ve.hpt here is the tune with the injector data and a few others,25-06-09 06-05-51.hpl here is the log from the scanner. seems to be running a lot better. thanks man for the help. the reason im doing this crap is that im getting knock in the scanner. id go weeks with out getting knock then i dont have the lapop hooked up then get a light, scan it says i have knock. i finally scan it and see it in the scan its at 4000 rpm. it say like 8 something not sure what that means here is the scan 25-06-10 15-20-26.hpl sorry brother. its the reason ive been changing everything. i changed the intake, the injectors, the tune, plugs wires, made sure all the exhaust gasket are tight in place, intake tight in place, made sure the exhaust itsnt rubbing or hitting the frame. thinking about going speed density call it done.
