Questions re: Weber 44 IDF carbs:
1. Is anyone running these on a stock engine, and if so, how do they perform? National Carburetors kit for stock engines is 34 ICT's, lightly modified 40 IDF's, and only 44's on heavily modified engines. 2. What problems do you introduce using 44's? other than dumping too much fuel in the engine...... 3. Venturi's are 45mm, someone pointed out that one should use 40mm venturi's - is that with a stock engine? 4. Anyone run 44's and then convert back to EFI? How did that go? Labor cost? TIA, GN |

So it's a 75-76 2.0L ECU? A 052?
I'd have a 914 buddy with a 75-76 2.0L install it in their car to test it. If its bad the car will run like crap or not at all but really if its a rebuilt unit it should be good. If IIIRC correctly the rebuild process just ran a series of tests and maybe resoldered some bad connections. If the ECU isn't hung like stock they can bang around and a solder joint could go bad. That's why they were hung off the battery tray so they avoided banging around. |

Geoff -
I kind of thought of doing that, but don't know any of the local guys with D-jet very well, not well enough to ask that of them. Don't see any way a bad ECU could hurt their system. All my local 914 friends are running carbs - or V8's! So I'll start talking to area 914 owners - I have a great list - and see if any are willing. Knowing the ECU is good would be strong motivation for me to try the D-jet - testing the other components isn't that hard, and I'd send the injectors to Dr. Injector, and get a new harness from Jeff for sure. AH! What about the distributor! I'd need a dizzy with the connector for the D-jet too - how hard are they to locate? and what is the Bosche number for them? Thanks, GN So it's a 75-76 2.0L ECU?

I thought there was a special set of contacts for the D-jet dizzy?????? That connected to the ECU....... If a 123 dizzy would work, why wouldn't my present nice 050 work?
