I just put a procharger on my car and got a map sensor for a cobalt ss from o'reilys and put a 2bar sd tune in my car. I adjusted the ve table like my old file had and adjusted for the bigger injectors and it wont start. But if I make the injector table bigger than they really are and cut the ve table waaayyy down it will hardly run playing with the throttle yet is fat as hell.*cloud of smoke behind car*

So i've been running a my old tune and just changing the ve table and have the injectors set the way they should be and the car is running good. But I would like to figure out what is wrong with my 2bar tune so I can use the extras that it has.

Im using Hp tuners, heres the tunes.

There are several things in that charged tune2bar.hpt file that could very well cause the issues, starting with your dtc's being set to mil on second error, your map sensor, I believe the cobalt map sensor is a 2.5 bar, yet you have your map scalers set for a 2 bar map sensor and maybe I'm seeing things but your VE table is set to 10 across the entire map.

A complete no start situation is rarely a "wrong map sensor" issue, its almost always a DTC or calibration issue that needs to be addressed.

Yeah the 10 thing was just trying to get it too start. I had no idea about the dtc's messing it up though.

I thought i've read were on here that somone used the cobalt map sensor but i'm not sure.
