Possible to damage trigger inputs?
Alright, I'm about fed up with this piece of **** ECU and would like to know the likelyhood of the following scenario.
Fresh install with a new E6X, the crank angle sensor (FC) that you use for the install happens to have damaged wires under the rubber boot. 3 wires with cracked insulation at the same point (high likelyhood of them touching eachother). The car runs like this but "randomly" (because I wasn't aware of the damaged wires) blows itself up one night.
Rebuild, reinstall, check harness for issues, run the car again with a new CAS. Car runs decent, but RPM's will "blip" randomly. As in, cruising down the road at 3Krpm, and the tach quickly shoots to 2500 then back to 3K - datapages will show 900rpm for an instant. Adjusting gain's SEEMS to make it go away, but 5 weeks of trouble free driving would reveal the blips again.
Then, while driving at virtually no load, (between 3 and 4K rpm, under 4psi) you hear the rattling tick of detonation and you blow a rear rotor. At the time of the noise there was NO variation in RPM and no hesitation like was typically felt when the RPM issue occurred - during this failure it simply knocked on its own.
Is there *any* possibility that the ECU could have been damaged by running the car with the botched CAS? My working theory given the random nature of the current failures is that its damaged. As much as I'd absolutely LOVE to put that ECU in the vice and crush it - the end goal here is to find the cause of the issue, so if its not the ECU....I'll fix it.
Should also mention I couldn't find any strange things while OHM'ing the harness. I looked at the CAS wiriing hoping to find a break or short....but came up with nothing. There's a few details left out of that story, but I'm mostly looking for likelyhood of damage given the CAS - and if it *were* damaged, what issues it would exhibit.
