Don't know if it worth the effort to even plan on using it with all the newer ECMs and "self tuning" software to get you in the ballpark quicker.

I have the wiring harness for injectors sensors etc. Think there is a wide band also.

Have you had a chance to try the system out yet? I used the same ecu on my twin turbo engine using methanol. It will not work well in closed loop using methanol but on pump or race gas it will work great. I ended up selling my ecu to a local guy with a twin turbo mustang and its been doing great.

I wouldn't get hung up on the self tuning function, you will be surprised how fast you will learn the software once you start using it. Spend some time in the passenger seat and work your way up the rpm range a little at a time in open loop. Then switch to closed loop and log the info.

My new fast 2.0 has the self learning mode and I've only tried it a few times. You still have to get the fuel tables in the ballpark for it to work well. I do just as good tuning it myself than the self tuner does.

I have an external data logger for that system if you are interested? You can still buy a new harness and get all of the electrical schematics off their website.

It was a nice ecu and I wish I wouldn't have sold it. But I build 3 megasquirt systems for the price of that system years ago.

Good luck, Im not a supertuner but I can try to help with questions if you get to that point.

Hey Skip, after a little digging, it seems it is possible to flash the 1.0 XFI ECUs to the new 2.0 version, using an option file from FAST. That gives the older ECU the qwik-tune auto-tune capabilities. There's info regarding here:

http://www.theturboforums.com/thread...I-2-0-Problems

There's a link in there to the FAST forums that has additional info too.

One thing I think which is a drawback is that if you ordered the 1.0 unit with data logging you lose that feature at time of upgrade, or that's what I got out of it.

Believe as long as the part number is 301000 you are golden. Not sure if there's a cost associated with the option file, I may dig on that a little more...
