Megasquirt

[Chris Percival]

I have brought and built a megasquirt board, including the stimulator and relay board. I plan on using it on my type 4 motor, once I have built it and run it in on carbs...

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

I’ll 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...

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 I’m 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
