Just wondering if you guys could share some experience about Greddy's E-manage and the SC Cobalt.

Does your ecu fight with it to maintain a 14.7:1 afr?

I'm wanting to be able to run larger injectors without running rich everywhere but wide open throttle.

HpTuners won't work.
Megasquirt isn't all that appealing after learning about it.
Hopefully Emanage will be more promising.

 

I know two Red Lines owners have put a Greddy E-manage on their cars and have had very limited success. They used the Emanage to control 42.5 pound injectors and as far as I remember the ECU still took over and ran the car so rich that it kept causing a rich code to be thrown.

 

whats wrong with hp tuners?

 

HpTuners won't work on my ecu because Gm locked the code.
HpTuners can't read it.

The car is a Cavalier with the ecu reflashed for the supercharger.

 

get a ecu from the junkyard and WRITE ENTIRE if infact the vehicle is compatible with the hp tuners

 

....?

 

If you have a Cavalier, you can probably just do a stand alone system like AEM or MSD. Piggy backs are designed to work with specific applications, and the Greddy Emanage only works specifically with Japanese cars. You can wire it up to other types of cars, but it won't work right.

See, us Cobalt L61 guys can't do stand alones because other stuff quits working, like our throttle for instance. But you Cavalier guys have more options.
