LT8s: How to go from 2-bar to 3-bar map sensor?
 

Hi,

I'm having a difficult time figuring this out. How can I upgrade from a 2-bar map sensor to a 3-bar map sensor??? I'll probably be running methanol injection sometime in the near future so I will definitely need an upgrade. I just want to know if their's an upgrade I can buy or will I have to ship my ECU back to Microtech??? PLEASE let me know.

Thanks in advance,

Rizwan

the map sensor is integral to the ECU, i'm sure you know what that means.

SHIT! That's what I figured. I guess I'll be emailing Microtech to see what I can do about an upgrade. Anyone done this before??? Thanks again.

the 2 bar firmware only supports 20PSI as i'm sure you already noticed in the maps. you can't change the firmware, only microtech can.

you'll need to run external map sensor setup like mine.
you'll have to sent it back to microtech for upgrade, tell them you want to run GM 3bar map sensor and you'll buy/have the sensor already. it was cheaper that way for me then buy map sensor from microtech.

yup. Or get thwe ecu reflashed. G
