I don't know what I am looking at in HP tuners but do you guys see anything obvious that is screwed up? I am going to get my wideband hooked up this week and start tuning on it but I wanted some opnions on what has been done thus far.

Thanks for Looking!!!

Starting to figure out why it runs like ****. He did not copy the values of a lq9 over to my pcm. Hell I made a list of what I did to the motor and sent it with my pcm. I just downloaded a stock 98 tune and the injector tables are the exact same!!! He knew I put red tops in!!! The engine selection tab was still labeled as a 5.7 and the cylinder volume was still for a 5.7.

Should I just start over with my own tune and copy all the data from a stock 02 LQ9 and go from there?

Injector flow rate is different. Not necessarily correct but they tried.

The engine type doesn't matter but the cylinder volume does.


Get the right info for those two things and just tune the airflow tables out once you get your wideband hooked up.

I compaired the injector data to a stock 98 file and they looked the same to me?
