My other idea is to switch to a 06 Caddy DTS ECM which is tunable but so far I noticed I would need:
a.) 4x camshaft reluctor wheels
b.) 58x crankshaft wheel (this would have to me mounted external because of the component location (middle of crankshaft)
c.) electronic throttle body
d.) electronic gas pedal
e.)E67 PCM (I actually already have one of these)
If I go this route, then the only "tuning" I would need to do is to remove VATS and the ABS/Traction Control logic that pulls timing if components are missing. However, I would have to figure a way to mount a 58x reluctor wheel because I'm not too interested in taking my engine most of the way apart to replace the reluctor wheel. Perhaps I could bolt it to the front of the crank pulley and just weld up a sensor mount like the Megasquirt guys do with the 36-1 wheels. I'm pretty sure I could pop the valve covers off and replace the camshaft wheels easily enough.
Is there a way to run the E67 PCM with a cable throttle body? That would save me from having to purchase the throttle-body and the pedal.
