Well that is not a bunch cheaper than the Holley HP, juz sayin

Thanks for the manual. Just a note. The software on this site has gone nuts. If you want to post a link to a document, you must remove the "front" of the link otherwise the damn thing will try and open. Very very annoying

In my case I upgraded my old Commander 950 to HP. For roughly that same price I got the plug and play Holley harness, the ECU and software, and a couple of extra sensors. They really weren't needed as the ones in the 950 were the same.

Well, I had looked into that...The Holley HP computer is 1,108.95 @ summit and then I would have needed the main computer harness (unterminated) which is $304.95 and an injector harness for $111.95. So that's $1525.95 and I would have only ended up with about $50 more worth of plugs than I already had. So, a delta of about $200 on an already expensive project.

Also, they are really restrictive on hardware...Its really unclear if the 36-1 wheel with VR sensor is even supported, and if they'd support the factory cam sensor for the '92-'03 magnum engines I am using. The 36-1 is easy to get custom wheels made, mine was $70 delivered and all I had to do was weld it to the crank pulley. The ranger crank sensor is cheap and easy to get (3.0 OHV vulcan engines are everywhere) and I paid a massive $10 for the magnum engine distributor.

I knew megasquirt 3 supported everything that I needed so that was the main reason to go there. Also, there's a ton of support available...not just a company's tech line. It really just depends on what you're looking for. Nothing's really a totally plug and play app for a SBM with SMPI and Coil near plug.
