Megasquirt ems
No, Redtruck isn't radical but she's a 03 model and I have fought with tuning ever since I first bought her new. I'm currently using a Crazy Spartan (lsa 112) with the basic add-on's. SCT doesn't support the 03 model hemi, Diable has issues with 03's and throws ABS codes and can lock the PCM so updates and other turners won't work, This requires dealership resets for the ABS problem and replacing the PCM for using other tuners. Plus Diablo/CMR tunes can't adjust idle, rpm/speed limiters. I've come up with a High idle mod to raise the idle but it really isn't adjustable and runs 800 cold and 650 warm.. Red is a street truck but I want total tuning control to give me the freedom of bigger cam and generally better overall tuning than my current SuperChip /PSC1-003 piggyback setup. Megasquirt looks very do able. But all of the trucks lights, AC, dash and accessories are run by the PCM. I would like to keep the original cruise which require the FBW to remain functional. So I'm going to try running the MS controlling only fuel, ignition and knock sensors. If that fails I'll go to cable throttle body and fab a new cruise control setup. MS recommends what they call a parallel install. Which is what I'll do.
