The beauty of electric components is they are expensive and cannot be returned once opened.
As far as corrupt output signals: I suppose that is possible but a DME is not an iMac. It's pretty simple and generally either works or doesn't. I was involved in one swap where the car owner ended up with three bad DMEs but they just didn't work. I've never seen all well but one output signal. |
Thanks for the input! I don't have access to a known good ICV and hesitant to get a used oem one on eBay or a China knock off.
I haven't have time to scope the output signal yet so I've been driving it with the ICV unplugged. The rpms get up fairly high 1400-1500 when warm and sitting at a traffic light. The engine will also start bouncing rpm from 1500-1100 like the dme knows it's idle is too high and cuts fuel to lower the rpm. I usually call this "DSM"ing because of the old 1st gen eclipses would have bouncy idles at times. Lol!
This is what I'll be testing.
