914World.com _ 914World Garage _ L-Jet troubleshooting

Posted by: mpoffers Aug 12 2010, 09:54 PM

I'm trying to troubleshoot/test my 75 1.8 L-Jet components, but I'm having trouble getting started. I found this:

Injection.doc ( 195k ) Number of downloads: 199

But I'm not even sure it's for L-Jet. If it is, the pin numbers on the large connector don't make any sense to me. My ECU has 37 pins.

Does anybody have a similar document that applies to my L-Jet?

Download it, pretty much the same stuff on the 912E as on the 914's.

It isn't. You can see the Manifold Pressure Sensor in the figure and references to testing the MPS in the list. PM me your email address and I'll reply with an attachment on L-jet; it's 7MB in size.

Had trouble with the 912E site, but found the document here:
