Default Trouble tuning.....Grannyshifting

I'm tuning on a 98 firehawk that Grannyshifting tuned back in the day. The problem is is that it seems to be using only the first row vertically in the ve table. I've never seen this before and don't know if Granny(Jeff) would or could've locked it like that. Any thoughts??

If you know how to tune it would be easier to start from scratch than to try and figure out what a previous tuner has done

It sounds like your not logging the airflow correctly. If you can download the tune then its not locked. Are you looking for a 6 speed or auto file? HPT or EFI?

I'm using efi live, it's a 6 speed. I don't know how else to log it other than logging it. It just does'nt move around the map as it should. There is a big jump in values from one cell to another and you can feel that jump in the car. I have'nt had this problem with other cars I have tuned.

Sounds like ascanner setup problem or the MAP sensor isn't working.

I will log a run in my truck and see if it works right. I guess if it works right on the truck then the map sensor could be bad on the firehawk. I was thinking it could be the map sensor too. Thanks guys.

Not every vehicle uses the same PID for logging airflow, have you tuned 98's before? Are you familiar with a backup VE? Is the car in SD? You should be already logging the MAP sensor on the camaro, just look what values its giving it. Do they seem normal at idle does it change when you rev it? No need to log another vehicle.

Everthing seems to be working as should. It just don't use any of the first verticle row of the ve table.

Post your tune & log file. Its either map sensor or your scan tool isnt setup correctly.
