Redline322,
The "biggest issue" is getting it to run in the car. Physical fitment typically requires custom mounts anyways, and a custom subframe/crossmember would likely be required no matter what. Honestly, it'd probably be easier to completely replace it than to modify existing parts.
It's never going to be as easy as a B or K series swap, but the fact that it's been done with a 1st gen MX-6 makes it much more do-able than previously thought. Picking the brains of the original project owners would probably answer a lot of questions
crazycanadian,

Easily 75% of the active membership would hesitate to swap harnesses, maybe half of those who would consider it would follow through... They would give the same reasons as those who nay-say non conventional engine swaps. "Too much work for too little gain."

A little info.. The ECU came from a car with an automatic transmission... I have nothing for automatic transmission hooked up... Also I have non of the emissions control systems hooked up... I am throwing 10 trouble codes because of all this stuff missing... I am not throwing any kind of code that directly relates to idle or any kind of drivability problem though... From looking at the video why do you think the car is idling as it does?? It will do this high idle every time you come to a stop light or touch the throttle..
To be 100% fair, mentioning only the current state of your car(after months of troubleshooting error codes and lack of tach signal, etc), without considering how much work it took to get it there... Is a colossal mistake. People will start thinking an OBDII swap is a bolt-on affair, and end up scrapping their projects because they lack what it takes to finish them.
Yes, it ran from the get-go, but it was far from "easy" to get it where you have today. Believe me, I give you mad props for what you've done, it's a hell of an accomplishment, and I assure you that I am not bashing your project, hard work, or end results... I just don't want people getting the wrong idea about the complexity of it.
PnP Megasquirt(only one aftermarket system, out of several available, the CHEAPEST by far for comparable features) is, as the title puts it, plug and play. I have verified this myself, having driven a bone stock K8 around town on a base tune with zero tuning. I went so far as to test the same ECU(with a KL base tune, downloaded from another forum) on my '93 KL swapped GS. Both ran flawlessly, without a single hiccup. 2 pop tabs, removing the stock ECU, and plugging in the PnP unit. It was a 5-7 minute swap, because I couldn't get the stock ECU to detach from the harness at first.
Granted, I didn't build the unit myself, and that saved me from troubles that others have discovered and overcome in the past.
