I have a Manx buggy that has been running a complete CB Performance, turbo EFI kit and it runs well. I put together a Megasquirt ECU to replace the untunable CB performance ecu. The buggy runs, but getting the boost enrichment to work properly is a problem. There is so much written about the MegaSquirt, but not much written about tuning under boost. The MSTweek program is great with the exception of the fact that the instructions for using it (MSTweek) to tune the EFI are incomplete and have been for some time.

I have a MS system, with an Audi A4T TB, sensors and injectors, Modified Audi fuel rail, homemade plenum. Itís for a wasserboxer but the basic should be the same for an air-cooled..

Iíll keep you posted.. Jesper

Hello Jesper,
I like your aluminium fabricating skills! Nice Throttle body you have made.

What is the flow rate of the Audi A4Turbo injectors in [cc/min]? They are probably low impedance, are they?

Poor Oval...

Greetings,
Walter

Hehe! Thanks Wally, But I must admit that I only made the plenum sheets holding it in place with tape! And had a friend of mine welding it together,

The injectors are Bosch no. 208 150 447 which give 241cc. High imp. (12 ohms) With cut and welded Audi fuel rails, together with a 944 fuel pump it becomes a nice set up!

Be carefulll with a turbo on a 2,1 ltr engine and 241cc injectors. They seem a little small sized for that. Forget where they came from or what the books say.
You don't want to lean out with a turbo...

Good luck,
Walter

Ahh, no Iím going to run it as a normal aspirated engine.. Not a turbo. Ported heads with 10.5:1 comp.
And W120 cam with Type-1 lifters.. So I think I am on the safe side!

I see, yes, then I agree (boring but I do).

But why then not keep the stock plenum?

Greetings,
Walter

Two reasons, first the old plenum will only accept the wbx trottelbody, which itís only 46mm and the A4 is 60mmÖ. In addition, I have made velocity stacks inside, where the stock just has four straight pipes going in, and it look cool!!

Ok I was checkin out the megasquirt site. Can anybody really build it and tune it? Im pretty electronically challenged so I was just seeing how hard it was for the guys that did it.

It was pretty easy. You have to be able to solder, but thats easy with a little practice. Just make sure you have the instructions and have read them through a few times before you start.. Test as you go. The docs are pretty good for building it..
