just wanted to get an idea of how many PRE 29.2 people are running a JB3 1.1v or 1.0v map (post 29.2) on there cars.

was thinking about doing this since i wanna be extra safe and if i get updated down the road i dont have to upgrade.

the differences i have found between the POST and PRE JB3 is

PRE vs POST JB3, POST JB3 or 1.0v/1.1v:

-More agressive solenoid duty
-Remap of the fuel pump to increase AFR( 1.1v is now richer then 1.0v AFR wise) "The fuel pressure is remapped as a function of boost and expected fuel trims. So basically only at wide open throttle"-Terry(fuel pressure remap only happesn at WOT)
-Little less WTQ(est 10WTQ)

i might have missed some stuff but that is what i found for now.




p.s. a little someting while i was reading.

ANYONE who is wants to know if they have POST 29.2 on there car. if you install a PRE 29.2 JB3 or 1.0/1.1 map, and have a 29.2 car,

"It will throw cel/limps as the ECU tries to keep torque below internal limits. If you have pre 29.2 then you can run the pre 29.2 map, and switch the chip later if needed."-Terry

so if your throwing CEL/Limps with a 1.0/1.1 you more then likely have a POST 29.2+
