Anyone else using MegaSquirt on a LA motor?

MopaR&D said

Newbie question, if I wanted to add EFI to my current engine (5.9 Mag with LA top end) using a MegaSquirt system would it be possible to build something that would also be able to control a later Gen 3 Hemi with variable cam timing? I'm guessing most of the 'controls' expense with the G3 Hemi swap would be the physical connectors, wiring harness and sensors?

Per the previous post, EFI Source does sells the Gold Box, which is essentially their version of the MS3X. You will still use Tuner Studio for tuning. If you buy one specifically for the G3 Hemi, it will come with a base tune and it will have the igniters installed inside of it to operate the COP coils. I do believe they have it setup to use GM style temperature sensor, MAP, and IAC, so you would have to fit those to the G3 Hemi. To answer your question if you could use this on an LA, and a G3 Hemi when you decide to change, the answer is yes. There will be some obvious configuration changes to switch, due to different types of sensor, ie; crank signal, cam signal, coil type, injector size, etc. You could try and use the same throttle body on both engines and that would eliminate some of the configuration changes. The thing I like about EFI is you can make just about anything work and it can run any engine. After all, regardless of brand, they all operate the same.
