FiTech EFI System??
No but he knows what he's talking about. Dave you think this might be Arduino based LOL
And that's cool--I just wanted a slightly more elaborate answer. I have some experience with older piggyback systems that used similar "crude" anchor points...they were more like 4x5 resolution, but that system also used the same interpolation of data input by the programmer, then the adaptive strategies in the base programming modified the calculations from those input anchor points by multipliers to make fine tuning adjustments that were transparent to the user. On the timing control, does it not adjust the timing based on load v rpm? That's what it looks like based on the description, and probably does do that. The system I mentioned above had similar anchor points for timing as well, but just because I input, say 24*, at 2600 rpm for increased load, the computer would still fine tune that number based on load tables, and sometimes the handheld would display as much as 44* at low load and cruising RPMs...I don't think I would consider that an analog of straight mechanical advance. Just trying to glean a better perspective of his statement.
As much as I agree that TBI is a primitive version of EFI, and multiport is an improvement, anything that makes cold start drive-away easier, and can "self tune" without having to change out air bleeds or squirters or some other modification to a metering plate, it may bear some scrutiny. Multi port on an engine like, say--the 383 I'll finally be able build after I retire from the AF--will require either a special manifold, or one modified to use those injectors, and an electronics suite to run it...one of the MS systems was on my mind, but if I buy that system new, I'm still out several hundred dollars (if not over a grand) just for all the hardware, then I'll need to download a base program and modify it to my needs, then constantly tweak it as needs arise to fine tune. While I'm not opposed to that approach, I'd prefer a system I can just install, make some initial adjustments, start, drive around for a little bit, establish some baselines and then be done with it.
Or did I completely miss something...?
