Since I went turbo the first time in 07, I had always ran SD, never had an issue?

1982Z28with18s (with the rx7) runs speed density I am pretty sure. The problem is, LT1s were never intended to see more than 1 bar pressure. The MAF maxes out, and then its hard to get it to read remotely right after that 1bar. My tuner when we god rid of my maf showed me a graph, and the MAF readings were all over the place.

 

Here's the thread to which I was refering...

Yeah, you just need a reputable tuner to do it, or do a lot of reading on how to do it yourself. My car was OBD1 and was pretty straight forward after he showed me what he did the first time. I used tunercats FWIW.

 

You mean the MAP sensor maxes out. The MAF sensor maxes out at 512gm/sec (over 500hp worth of air), which is 7+ psi on a stock motor.

 

MAF maxes out, I was pushintg 10psi and getting funny readings on it. I know the MAP maxes at 1 bar. I was running a 2 bar MAP with a SD setup

 

Yes there was a baro reset problem, that's been fixed. You need to either download the file in that link or run the latest Tunercats to access the settings.
