12594942 map sensor

[Halfasd]

Hi all, I'm getting started with my first tune. Have a question regarding the map sensor, 12594942. I cant really find any information on it. Appears to be a 1.3 bar?

Im running a NA ls1 with aftermarket intake, which doesn't accept the factory map. I had this one laying around from a ly6 or something and thought I could use it.

I did an os enhancement to 2bar, which allows me to set the linear and offset.

I'd think it would be OK. But don't know the values. I have a hunch...
Thought I'd Check.
Thanks!

128.20 and -0.30 should be the settings.

128.20 and -0.30 should be the settings.

That's the first value set I used. But then my key on engine off pid reads 89kpa

Here in MN, it should be more 101kpa ish.

Also, can't use negative offset!
Thanks

The kpa will depend on the day, we aren't below sea level here in Minnesota. High 90's is the average I see.

If those settings don't work then it's probably going to be 94.43 and 10.34 for the other GM map sensor used.

Weird that is says you can't do a negative offset, the table on my computer says I can and it works for me to put negative numbers in.

I'll give it another go tomorrow.. Appreciate the feedback! Been fun so far.

MAP offset value in HPTuners software version 4.10.5 is only 0-640Kpa

I still running 4.6 or 4.8 because I will not update mine anymore with the recent changes they have made in 4.10.

[Halfasd]

Any examples of what they changed that was bad? Sorry, I only recently started!

[5FDP]

They removed certain things tied to emissions, so those can't be turned off anymore.

I follow you. Will have to track down an old version
