What would be the difference between the 3 bar map and the 2.5 bar map
there is 20$ difference the 3 bar is at 29.99 and 2.5 at 49.99

if i get the 3 bar would it still be ok?

 

iirc, someone on here stated that we could not use it.

go 2.5. try to find on on here for cheaper or a bone yard.

 

Thanks

 

2.5 is easy to wire in.

this is the connector needed

2 bar MAP, GM# 12580698.
I believe the peeps that use a 1 bar have to scale the MAP tables differently ???

 

this however theres a new PN for it through gm.. but that is the one zzp ships thats PnP

 

Sorry for the thread revive but I want to know if the wiring diagram is good for the 2.4 stock maf sensor. I've read that some mafs are different and black was actually my black and the tan is my tan on my car.

Thanks!

 

My 07 2.4 iat wires at MAF are tan and tan/black.

I'm getting ready to hook up the lsj 2.5bar map, just trying to make sure.

 

I figured it out but I can't get my IAT2s to read

 

HELP MEEEEEEEEEEEEEE !

I installed Saab intake mani and am using the LSJ 2.5bar MAP sensor with IAT.
I was told to make this change for the new LSJ map, engine-diagnostics-
MAP SENSOR LINEAR= 270.59kpa and
MAP SENSOR OFFSET= -3.30kpa.

I did a WOT 2nd gear pull and my MAP kpa reading is only 145kpa this at 11psi.......hmmmmmmm

Where as before with 2bar MAP at 10psi I got readings of 175kpa.... which makes sense to me but not the above.

what have I DONE WRONG ?

 

Yeah the tune...

Remote tune is never gonna be dead on, i'd ditch it and go with a local tuner

 

pretty sure i'm using either a 3 bar or 3.5

 

ANYBODY, ANY INFO ?

Thanks

 

you can rescale your map if you are using the stock sensor

 

^^LSJ T-MAP sensor, not stock for LE5

 

Soo I just installed my supercharger the car runs, but the map sensor readings stay at 79kpa no matter what the operating conditions are. I'm using the 2.5 bar map and running the iats through it. Any thoughts?

I have a 2007, 2.4L

I've wired it according to the drawing that gets passed around all the time. The only thing I didn't understand was the low reference from the maf sensor. Does it get spliced in with the stock low reference? Making the two low reference wires into one?
I read that all that is to be done is to cut the low reference from the maf and do nothing with it...

 

My low ref signal is two into one and works fine. I have no unused wires.

 

i have a 3 bar i can sell

 

How are e67 users utilizing anything above 1 bar when the ve table ends at 105kpa?

 

I think its just for the fact of seeing boost in the logs, everything else is maf

 

MAF uses VE, VE uses MAP ...

 

i think most people tune their cars "maf only"

i was reading a thread you were posting in over at hptuners forums and i realize while ve is impossible to completely disable, i believe most people live with stock ve tables on the base model cars.

pretty sure lsj has a regular style ve table

 

also i saw that you added to the axis and cobaltssoverbooster described that this should work. I requested the beta and may be trying it out for myself shortly

 

Have you figured anything else out about VVE? I have had ZERO success getting even a single word out of HPT tech support or forums. Starting to become disappointed in HPT.

 

Its still in the beta stages so you cant expect it to really work how it should or expect great support.

I havent really played with it too much but it all seems to make sense for me anyway.

I read somewhere on hpt forums that changing the map and rpm boundaries doesnt affect the vvt parts of the ve equation so it wont work because of the different axes... I havent tried loading anything onto my car with it yet.
