Name: Steve Hauer
Vehicle: 1977 BMW 320i
Engine: 2.0 Liter I4, header, cam, 9.5:1 CR forged pistons.
Injection: ITB port injection using TWM 2900 series throttle bodies, 24Lb Delphi/Lucas injectors, Stepper IAC, EDIS
Description: Converting from dual Weber DCOE 40 carbs. Megasquirt specs are below in my sig.

This is a nearly fully restored BMW 320i (e21 chassis) with 76,000 original miles. I converted the stock kjet injection to dual sidedraft Webers last year but have not been completely happy with the carbs for daily driving.
My plans for this project are to first install the EDIS components and get EDIS working with my carbs. Once I have my MSII running in ignition only mode with EDIS I will removed the carbs and add the TWM throttle bodies and other EFI components.
Current status is that I just got my MSII assembled and tested about two weeks ago and I got EDIS up and running this last weekend. I figure I have another week or two of playing around with EDIS only and then I need to wait until about mid April for my throttle bodies to arrive.
The only issue experienced with EDIS was the usual problem of getting my tach to respond to the EDIS CTO pulse. Some minor changes to my tach input circuit fixed that.
The website listed above goes into detail about the portions of this project I have already completed and some of my plans for the yet to be installed EFI components.
