A juicy girl got me, again
So I've had this crazy idea ever since I swapped to an 0411. How can I make it run flex fuel?
Here's me thoughts:
I have a flex fuel OS out of a 2002 tahoe. The tune is set up for a 24x crank signal and COP ignition. The easy thing would be to swap to that and run the tune no problem, but $$$.
The tune has the option for a Lo Res crank signal, i.e. standard l31 4x. Obviously I would need to swap the injector pins to account for the different firing order of an LS. But the tune doesn't have the ability to run one ignition coil instead of 8. I wouldn't think the signals would be different between the two types of coils.
I believe that if I y'd all 8 ignition outputs on the ECU to the single wire controlling the stock coil it should work. I'd also run a diode on each ECU ignition output to make sure it doesn't fry itself.
I already have a spare 0411 in case it still frys it, and I need to pick up another ignition coil just in case.
What do y'all think about this endeavor?
I did try the OS with all tables copied over including the firing order. It started but wouldn't continue running and was obviously missing a few cylinders.
