uberdata & 3bar map sensor
 

I'm about to swap to a 3-bar map sensor on my y7. in uberdtata can I rewrite the values for the in/Hg row so there is not such a big difference between them? I want to run 14-16psi so i really wouldn't even use the first two or the last three columbs in the fuel and timing maps. can i rewrite the values or will that ---- it up?

As far as I remember the 3 bar support always sucked in Uber.

that sucks

It works fine. What sucks is the non linear GM map sensor.

I have tuned numerous 3bar map sensor cars. It just takes some fiddling.

93turbo16, have you changed the values in uberdata in the in/Hg row to get a more precise reading? you're saying its the GM map sensor that makes tuning hard ?

That and the non-understanding of the map sensor when they wrote the 3 bar support. But it does work. You can change the headings. I have done it a lot with the 2.5 bar sensors.

it works perfect for me.

i tuned 3 bar on uberdata with no problems.

currently at 622whp on boosted ls/vtec. he ran 520+whp for a year on it as well.
