But not one that I remember reading. The MAP or TMAP as it is now on my Ecotec is a 2.5 bar. If i start a new tune on a NON reflashed ecu do i have to fake a 2 bar or can i use the tables for a 1bar just fine even though its realy a 2.5.
You'll have to fake the tune. The MAP sensor sends 0-5 volts. The actual map reading at say 2 volts is different on a 1 bar map sensor than it is on a 2.5 bar map sensor. Make sense?
or you can wire in your old 1 bar and IAT
1989 Turbo Trans Am #82, 2007 Cobalt SS G85
id like to not rewire
but may just have to i guess
Yea im just gonna rewire back in the 1bar and iat.
