Hey guys, I have come across someone who is willing to part with a megasquirt for cheap. I just need to finish assembling it and make a harness for my car. My question is, how exactly does a standalone ECU like that do all the same things that a stock ECU does?
Do I need to pull the stock ECU's program off of it's ROM and load that into the standalone? My main concern is: will I be throwing engine codes all the time by replacing with a standalone? I know that putting a megasquirt on a 5s without going turbo might seem like a waste, but if I get it cheap enough I see no reason not to go for it. I also know that I will need a wideband, which I should be able to pick up for like 200ish. Is anyone running a megasquirt on a 5s currently who has any advice to impart? Also, yes I did use the search function, most of what I found was dealing with 3s motors. I will be updating this thread as I learn more about how this works so that others in the future can learn from it. Thank you, Nate This post has been edited by Arsaces: Mar 7, 2012 - 1:00 PM |

I don't believe my eyes when I read that a stock ECU with piggyback is better than a standalone...
That has to be the worst advice, tuning-wise, I've read. That said, OP, like Smaay said, all you need is to figure out which pin controls what and tap into the stock harness and do it. If you have someone who knows what they're doing, do it. I have a friend running MS-II on his 5s-fe MR2 and it's the best mod he has on his car. The thing lets you do whatever the f8(^* you want. -------------------- 1993 Celica GT Coupe - sold

I don't have a "friend" who did mods... i actually did them myself... so speaking from experience...
