I still want to do this, 3+ years on... What kind of inputs, exactly, does the controller need? and is it absolutely necessary for it to receive some kind of signal over the CAN bus? If so, is there anyone out there that can dig up technical details like the CAN ID, table numbers, and offsets and what particular functions they refer to? Thanks.
What are you wanting to do? Run it as a standalone without a GM ECM?
Yes, without the E92, because the engine it's going on is still "dumb" without cam/crank sensors and obviously not GDI injectors.
The engine controller does have modifiable CAN capability...
Yes, it needs to receive information from the ECM about RPM, Torque, pedal position etc.Quote:

CHeck those out.
If you had to do it from scratch.....Quote:

The link above is for the 6 speeds 6L80E/6L90E not the 8 speed.
GMPP offers a stand alone 8L90E for use with there crate engines kits for older cars. Unfortunately what they offer is not very clear. I don't even see the controller kit for the 8L90E.
The controller they offer is to be paired with their own E92 setup. I believe that on the link that I posted that the emulator works for the 8l90e too. Contact them....
The 8 speed can be made to work with the E67 though.
The Non direct injection crate motors they offer like the LS3 run on the E67.Quote:

This is the exact combo that I was looking to mate together so I appreciate any help sir
Bump, did anything ever come of this?
