3 bar map sensor - 411 PCM

[badls1]

I have been struggling to find a 3 bar map sensor that works with efilive via a 411 ls1 computer.
Last year i tried a old style delphi 3 bar map and had nothing but issues. There was a blank area in the tune that i could not change and would go real lean every pass. Car drove low rpm fine and was reading boost over 20psi. Swapped back to my 2 bar map/tune and the car would run/pull fine.
I have been running all year 25+psi on my 2 bar and really need to get this figured out.

Which 3 bar map do you guys recommend/have experience with at high boost levels on the 411 pcm?

Thanks

Anyone run 3 bar making 25+ psi?

I'm runing ZR1 3 bar map sensor but the problem the scaner can't log morr than 255 kpa which equal to 22.5 psi
so after that you can not correct the boost VE table

255kpa is actually NOT equal to 37psi.

255 kpa at see level equal 22.5 psi
255 -101 =154 kpa

Yes, you are correct. I work more with compressed gases than I do with boosted engines.... my mistake, and my previous post has been edited.

Thanks. So it sounds like the zr1 is just a 2.5 bar like my dpe.

On some LS1 OS's there is a PID 'GM.MAPBOOST_DMA', that'll read above the SAE.MAP PID's limit of 255kPa.

Thanks Paul I will check if its available in my car with COS5
