I'm getting ready to pull the trigger on a diypnp. I am also about two months away from swapping my motor and trans. Should I remove my LINK and install the new ecu on the current setup and get it running again, or just wait until the new motor and trans goes in?

 

1 change at a time. You don't want to be troubleshooting 2 things at once.
Put in ECU learn how to tune it, get it running half decently.
Then put it the new motor.

 

The inverse also applies, you could install the motor, make sure it runs well, and then swap in the new ECU. Personally, I would do it this way, just because _occasionally_ people seem to have issues with the megasquirt that randomly pop up. ( However, this is going off of the assumption that the new motor will be brand new and will require a break in period) If its is a good used motor, I say do the PNP now.

 

PNP now, then the motor. If you're going to be learning software it's better to learn it on the motor you're about to take out rather than the one you just put in.

 

Thanks guys

The software aspect seems daunting. Hopefully between all the members here and diyautotune it won't be difficult getting things set up.e

 

According to popular belief, if you have a working neurone then you can decently tune a megasquirt by yourself, I for example have none

I agree MS then engine. Congrats on getting rid of the Link

 

My thoughts exactly.

You know the current motor's moods and habits, so it'll be easier getting a new ECU up and running on it. Likewise, if you're gonna do something really stupid and break an engine (I've never done it, but I guess it's possible) better to break the one you're planning to replace anyway.

It'll be a little more work overall (you'll probably have to tweak the tune a little after the motor swap) but this would be my preferred order of ops.
