So ..... Seth @ Dealer Alternative (the original FM shop here in New Jersey) is convinced that my car's massive misfires are due to some problem in the Megasquirt itself. He doesn't think the problem is the retrofitted NA CAS, and he says he spent lots of time checking out the MS wiring harness (which was carefully built by Paul, so I know it's good stuff) ..... meanwhile he says the car runs fine on the stock computer, except during idle, because it's got 460cc injectors.
I can't afford to keep driving a rental car. Thus, tomorrow the 460s come out, 305s go in (thank you OlderGuy), and I stay out of high boost. No biggie; it's winter anyway.
Going to send my MS back to DIY (they built it) and let 'em see what they can find.
At least I'll get out of this ******* Taurus and back into my Miata.
Just for fun, since it'll be on the stock ECU, I'll get to re-experience the infamous MSM "bog" which nobody ever solved. Oh joy.
Looking ahead, next month I have to pass OBD-II inspection. Hopefully there won't be any CELs due to the extra fuel (stock was 265cc injectors.)
It will be interesting (or maybe scary) to see what my wideband says about the 305s on the stock computer.
Sometime in the future, if DIY says my Megasquirt is not broken, then I really want to try adapting a trigger wheel to work with the NB sensors, or attempting MS-2 in parallel. Probably not until next spring at the soonest.
Bottom line, for now I am happy to be getting my car back (probably tomorrow or Thursday), but I'm depressed being de-squirted. :(
In other news, the woman I recently started dating is kinky and a total airhead. Will probably get bored of her and go back to demure-and-smart women. Until then, at least I'm getting to squirt using another definition!
