Best 3 bar MAP for 411 pcm What is the best 3 bar map to run with an 01-02 411 pcm. Will be doing a pcm swap and want to do this at the same time. A part number and/or link would be great
I would just get the LS9 map sensor but you would need a new pigtail harness or adapter and figure out how to mount it. It's a much better and more accurate sensor than the old block style 3 bar map sensors.

Various vehicles used various Operating Systems.
Some if these simply won't convert to 3 bar. Some will convert to 3 bar but with a reduced resolution VE table.
Others convert with a nice high resolution VE table.
I can say that the 99-00 Fbody OS works well. Even if it's in the 0896 PCM. I'm using one in my nova.
If you have a 0411 PCM, no guarantee the OS in it converts nicely. But you can rewrite the PCM with a 99-00 Fbody OS then convert to 3 bar. But that would cost 6 credits. Prob best to somehow get a PCM with a convertable file. There must be a list somewhere.

I bet that tune works fine.
That would be a good map sensor.
I see tick gives the linear and offset.
You need a pigtail to wire it in.
And you need the latest version of HPT software so you can enter the neg offset.
Good luck!

That old style 3 bar block map sensor from efi source will not read below 40 kpa and the spec sheets for those 80's era sensors show an 8% varience, that's a lot. You asked for the best and picked the cheapest.
