EFI -3G hemi

For you guys that want to keep the efi and drivability that goes with it. I MAY have another option. I read on the net of hemi cars on the road with the MSD ignition better known as the hemi-6 with megasquirt controling the fuel. Which you could do too ,but not real user friendly.
FAST has a similiar control box for the ignition , the XIM 3013142 handling ignition for the factory COP . Sells for $625
FAST also sells a self tuning efi standalone system called the fast EZ which can control 8 injectors on a port style manifold. Sells for $873
I believe the msd-6 setup sells for similiar price with harness price added.
Horsepower TV recently had a stock 5.7 on their dyno with the EZ setup with the throttle body style injection on a carb style intake that self tuned at 400HP after a few pulls.
The only hangup is the throttle body, worst case is that FAST sells a 112001 adapter to fit a lsx gm style 92mm TB to the hemi which is $380 and the adapter is $65.00 converting to a cable drive.
I believe you could make an adaptor which is just a piece of aluminum with two bolt patterns and adapt something like an edelbrock 350-3864 an ls1 style 90mm that comes with the TPS and IAC already on it. Sells for $332.
The EZ is setup sensor wise to the gm style sensors,Map,coolant, IAT etc, as far as connectors, which wouldn't be that hard to adapt.
This could be an under $2000 option that would eliminate the headaches associated with the factory wiring and drive by wire TB. And can be tuned yourself .

Lots of info on the net, found this on youtube:
