The programming side of things is becoming interesting, annoying, frustrating, and so cool. All at the same time...and sometimes allf four with the same issue. Like, take the tach signal. I swear it worked on the first start up, but the oil pressure sender wasn't...so it got shut off quickly (and obviously I was focused on the zero oil pressure.) Since then, no tach signal. Now, it turns out there may not be enough of a voltage drop off the coil to trigger the PDM correctly, and there are solutions, but in the diagnosing of all of this a new problem has surfaced. If I have the tach signal attached, the whole PDM freezes after the starter shuts off. Didn't do that the first few start-ups, and doesn't do it if the tach signal is disconnected. So did I fry the SPD1 circuit? Is it just freezing up because the signal isn't what it expects? Who knows!?! Diagnosing the issue, while frustrating, is actually part of the fun for me. Building on my knowledge base is rad...but sometimes I just want to be putting the weatherstrip on the car, finished, so I can go for a blast around the block!
I probably have to post up a video to YouTube to properly link here, but if you're an instagram user...check out the startup. Almost instant once you hit the starter button. Pretty stoked on this.
