ay CSS, i was wondering if a 2.0 map sensor will work in a 2.2.

 

Yes, I have one working in my car. You will have to get a tune for it to work.

 

coo, thanks for the reply. i need one for so i can get my meth injection hooked up and workin right

 

No problem. You'll have to do a IAT1 to IAT2 conversion though.

 

whats the reason behind this though??

 

Too see iat2's :p which on a turbo shouldn't matter bc the maf will read iat's after the ic and before the engine

 

so would this benifit for me?

 

how do i go about doin this conversion?

 

The way to convert from IAT1 to IAT2 is in my supercharger build thread.

 

If you maf is between ur throttle body and intercooler than this won't help u

 

yup it is i dont see any other way to run it before the IC lol

 

Yup, u don't need this conversion, and wouldn't benefit u at all. Ur maf is at a post intercooler position so the iat it's reading is iat2 bc of it's position in you set up. Had it been in the turbos intake I would be iat1 as it's pre intercooler. So if u wanna see ur iat2's just use a scan tool or interceptor to watch ur iat's

 

 

ok, so im still a little confused about this. the 2.5 bar MAP sensor has to be rewired to where the stock MAP sensor was. but reading in Genes build it talks about wiring it to the MAF so the IAT2s can be read. sooo i gotta splice into the MAF? my set up is blow thru.....haha, blow..lol. anyways can someone please clarify this. i got the lines for the meth ran and all thats left is to get the MAP sensor and fill up the tank and tune

 

yes, the map sensor replaces your existing one, so you wir that up, and the iat wire gets wired to your MAF's iat wire, so it replaces it, so now what your ecm thinks is IAT1 is really iat2, so you can monitor it on a scan tool, and vince can see it while tuning

 

Basically what Jn2 said. The IAT1 is read at our MAF so you have to cut the IAT1 wire and run a new wire to the MAP and connect to the third MAP wire, which reads the temp.

 

alright, got ya. and the LSJ map sensor is a 3 pin right? i was looin at my stock sensor and it was a 3 pin. i just wanna make sure everything goes correct. can you tell me which wire i have to wire to the MAF? any photos of wat wires to cut?

 

anyone have an answer? a photo or somethin?

 

nope. The 2.5bar MAP/IAT2 is not a 3 pin, as it is both a MAP and IAT2 sensor, whereas on the L61 the sensor is solely a MAP sensor. (the LSJ one is either 4 pin or 5 pin, cant remember)

 

so if i got a LSJ sensor the extra pins get wired to where? thats where im confused at

 

^ the MAF

 

i get that but im sayin what color wires do i splice. and if the LSJ map sensor has 4 or 5 wires what do i do with the extras?

 

3 plug to the stock MAP harness, and 2 go to the MAF. Check Gene's thread or Beck's for specifics on which wires are for what.

 

awww, thats the answer i was lookin for. thanks

 

On my setup only 1 goes to the MAF.
