After all the time and money on the rebuild, etc, I would advise against using the 7mge ecu. Since you already have the 7mgte wiring harness, the 7mge ecu will not work too well and it makes more sense to just go buy a turbo ecu (ebay, SF WTB, facebook marketplace, offer-up, etc.).
Get it running first, and break it in.

I'd struggle to use the factory ECU. Perfect time to go to a known reliable stand alone. Our 93 ECU has been fixed twice and still has issues.

Lots of good ECUs available for that that give you a TON of control and logging, etc.

Costas
cars and such...

 

What the other two guys said…. Just wanted to add though, if you even have an inkling of wanting to go to power levels beyond the upgrades thread that oldbonus linked (and maybe even if you stay at the upgrade levels listed in that thread). Just do yourself a favor and go standalone.

I did the whole “I just want a little bit more power, nothing crazy” and thought I was saving money not going standalone… guess who kept saying “I just want a bit more power” until they needed a standalone and wasted money not doing it in the first place??? It was me… I’m the guy.

 

Alright, I'll keep that in mind thanks.

 

If you can afford it, go stand alone, but make sure you talk to local tuners before you decide on which stand alone you get because if local tuners can't tune a specific ECU then you will be SOL.

 

If you went the 7MGTE ECU route, you would need to confirm injector size, get the right AFM, and possibly other sensors. Who knows what that guy was running before. With standalone, you don't necessarily need to change any sensors. Just more time setting up in the software. If you have a frankenstein setup with a mix of 7MGE and GTE electronics, you'll be doing testing either way to confirm what you have. Although, it sounds like you have a GTE running on a GE ECU... so makes sense it blew up.

A lot of us run ECU master black. They have PNP harness and a base map for 7MGTE. More importantly, lots of support from the community and from ECU master themselves. That can make a huge difference if you're the DIY type.

 

by the time you get your hands on a correct ecu and whatever missing pieces filled in from ebay or whatever, you likely will be spending most of the way to a standalone anyways. parts, especially electronics, are not cheap, and hard to come by these days. unless you find a member here or someone getting rid of their old stuff cheap after going standalone.

Another vote for the ECU master option.

 

Yeah I think the standalone is probably the better option, thanks everyone.

 

i have a brand new proefi128 set up im willing to sell for a very very good price if your interested.
