If I remember right, I was using around 3-4lbs on my Weber. Should probably use about the same.

$675.00 The thing I have been trying to figure out is if I can use a injector controller. I want to stay away from a ecu for a while.

you could use an injector controller but they dont conpensate for coolant temp or air temp, it wouldnt be any different than a carby

Do you think more HP then my Dellorto ? with say 550s and a injector controller

j9fd3s 03-28-2003 02:59 PM

yeah it should, but the mixture will need to be tweaked everytime the wheather changes

that would be annoying, find a EFI controller solution that has coolant and air temp inputs and it would be fine, that throttle body setup looks similar to what I'm putting on my 13B from tWM.

Does TWM have a website I found this on on mazdadragracing.com. and what EFI controller would you use that wont cost a arm and a leg

you can find megasquirt there, it looks like it supports the most common inputs for correction factors, the

features / specs are here:

BTW, injection perfection also makes fuel injection conversion for rotary engines...
