hey guys,how do you wire a map sensor into a vx l67?

well a VX PCM doesn't support map unless your just using it for logging & need to wire the ref pin to which ever wire your logging & then supply 5v to power of map & earth to the other!

But really need to know the complete setup & what it's for to help anymore!

essentially for a mafless tune,car is being converted to e85 an the tuner said it's good idea to put a 2 bar map sensor on.

still not enough info, vx is not capable of going mafless (2 bar map) unless you go kalmaker or older style PCM option!

he's going to be using kalmaker to do the tune,thats all i know lol.

the vx l67 should do kalmaker fine, the kalmaker tuners good ones usually install map sensor.

Any reason for going kal, what mods have you got?

headers,smaller pulley,1.9 rockers,twin 2,5 sports exhaust i want e85 due to the tuner has an l67 is running e85 he's it's the best thing he's ever done and alot of the americans with non cooled l67's said they gained anywhere from 30-50hp running it.

i basically just want to wire my own map in so i save a few dollars,just need a diagram lol.

ask the tuner then, it'l be kalmaker specific.

When I do mafless on VX etc I insist on installing my own MAP sensors. Plenty of trial and error went into finding good quality sensors and have bought some that didn't calibrate and were even as much as 30% out at atmosprheric pressure!

Given plenty of opportunity for error why would a customer install their own sensor?

Did anyone figure this one out wanting to do the same ............
