Searching for an assembled, used Megasquirt 3, or 3x ecu. I've got money ready on paypal!

You would be better off buying a new kit, and assembling yourself. If you don't feel comfortable assembling it, I'm sure you could find someone who will. There are some things that need to be done much differently for these old 5 cylinders than most other engines.

How much you wanna pay? I have a full 3x that uses lpt ports in a box somewhere but trigger inputs need work and adjustment, probs 60-2 wheel would be your best bet. Never was able to pickup the 2 flywheel signals properly, even with an addon splitter board (jbperf wheel translator). Mind you i didn't have an scope at the time, just using leds. It's also been a long time ago so maybe better options exist now. Since i don't remember what's what, it would be as is/no support from me. You'd likely have a lil bit of soldering to do.

Yeah i know its best bet, but I dont have time/the space to assemble it, and nobody local to me is willing to assemble. And I need to get the car running, but i cant afford the full price for an assembled unit. Mainly because people keep showing interest in parts I have for sale, then decide they dont want them right before they claim they're gonna pay.

A little bit is a lot better than assembling the entire board myself haha. I'm looking in the 450-500 range shipped

Ok found it, looks like i also put in knocksense (no clue if it works lol) and a bonus, mapdaddy.
It is missing some screws for the case and lpts so you'd have to source that. Looked around can't seem to find the tapered screws.

What are you planning to install on? I have a aan harness welded to lpts but the soldering job is not very pretty and coil grounds should be redirected.
