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.

Watch your OS.
I have a 0411 PCM out of a 01 Sierra. OS won't support a 3 bar so now I think I have to swap to a different OS . Just a heads up if you don't know and run into it

Would an OS from an F body allow 3 bar OS? Im not tuning it and know very little about tuning. I may have a custom OS

Sooo OS stands for what operating system? I also have a 411 PCM out of something like a 01 V6 Astro. ... I was told by PSI harness that any 411 would work fine with my HP tuners pro and a 3 bar?

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.

That's the one I'm looking at. You have the data for this one to be putin hptuners?

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!

nearly all the maps are GM spec or close enough to
ive always used GM spec's for every sensor

Will this one fit a ls6 intake with modification?

I also used the 3 bar map from efi source for my car. It works.

the efi source 3 bar works awesome. i have a stock cam that obviously runs about as much vacuum as you can get and i have zero tuning issues in high vacuum or idle.

Part no. For that efi source map?
I may have missed it

already posted it haha but since you asked so nicely

there is the link.

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.
