What will a 3BAR sensor read on the Diablo - SRT Forums

Was doing a datalog and was wondering what the 3 bar will read in the log? I am getting 15. Thanks

what?

it will read whatevers at the manifold...

Mine was reading 15.00 with the key off, wanted to see if that was correct. Thanks

should be around 0.0 key off, -14.5 idle

No, your baro is 15 with key off and the manifold pressure reads atmospheric pressure with the key on engine off. I have had mine ready up to 43.45psi. That's absolute boost pressure, which adds atmospheric to the actual manifold pressure. I would say the sensors peg out around 29ish psi.

What would cause the dataviewer not to read over 18psi even if you have 3bar sensors that work correct and everything is scaled correctly? Nigel can varify this.

First off, how much boost are you running? Next are you sure your reading the correct PID? Last I would check the rescale, just to verify that it was done properly.

26psi. Im doing avg map to use - baro, always 18.36 - 18.62 when I run 20-26psi. Had it double checked.

18.36-18.62 is exactly what the Stock sensors and a Stock map scale would read.

You either have 3bar sensors with a stock map scale or Stock sensors with a 3bar map scale.

Check your Baro at Key ON Engine OFF and compare it to MAP. It should be off by quite a bit.

Mike, I'm looking at the last log you sent me and your Baro is reading 14.3-14.4. That's perfectly fine. I told him to try a locals 3 bars to see if that changes what we see.

Yea Im gonna try that once I get someones that I know works.
