Should I install my Megasquirt before the turbo?
 

Hi, I searched but didn't see a thread about this. I have everything ready to go for my turbo install and was wondering I should install the megasquirt and get it up and running before doing the turbo. This car is my daily driver so downtime does matter.

Thanks,
Eric

id say get the ECU in and make sure the car is doing running decent........but you dont have to.

Eric, I always try to change the least amount at a time. That way if something goes wrong it's easier to diagnose. Plus you can get your megasquirt installed and tuned. Then when you get your turbo you just slap it on and ready to go. I live in houston as well and have tuned quite a few Megasquirts so if you would like any help pm me.

Yes, only way to do it.

I'd say it'd be much easier to install an ecu when you know the motor is running fine than to make all sorts of changes and then install the ecu. If you did the latter you'd have more heart ache trying to track down issues.

Thanks guys, that's pretty much what I was thinking. Just wanted to make sure I wasn't over looking something.

Change as little as possible without having to redo an excessive amount of work.

Not only what he said, but then when you makes those changes:

1. You already know how to tune and are familiar with the software. This means not blowing your load all over the road.

2. You get to hit the ground running. It was really nice having ALL the supporting parts in place (clutch, MS, injectors) well before the day I bolted the turbo hardware on. I was doing 10psi within hours of the install, without a worry. MAN was that FUN.
