I just did a manual swap into my 91 GXE and I am using the auto ECU and the freakin thing runs great. I will be upgrading my ECU and would like to know what exactly is different between the two ECUs anything important? Can they both be erased and totally changed over to a manual or auto?

 

nothing important, the auto has some extra "stuff" IIRC

 

i still havent seen the insides of an auto VG, but i imagine it is the same as the 5-speed, but with some extra features for the tranny...

yea only extra feature is the power/cumfort switch for the auto, but that just goes to the tranny controler.

What does IIRC stand for?

 

If I Remember Correctly

on the VE30DE engine, the ECU controls the variable intake on the 5-speed. I used MrGone's AT ECU in mine and the car ran fine, but the variable intake never kicks in.

 

wow........5 spd. max ECU's can be used on autos. nice. I thought you guys we BSing about that. you weren't kidding.

 

other way around.... AT ecu in a MT car

i dunno if it works the other way yet...

Brian

 

yeah, I have a 5-speed and I used an AT ECU in mine, just to see if my ECU was failing (it wasn't, it was a rear coil pack). I also have a spare 5-speed ECU.

 

Its kind of nice having both ECUs, that way I can program one and have the other as a back up.
