My plan is to run VEMS V3.3 fully integrated on the stock harness. Vems will be attached through a short adapter harness. All stock sensors will be used.

Here is a picture of the powerplant.





Small update from Jakob is coming. Basically he has used a GT1 Hall-sensor and 4 teeth on the front hub instead of the HEI module and the engine finally runs as it should.

But almost immediately after he got it running he has lost the wideband lambda sensor, he has tried two different LSU4 now and they both read 12.4% (under what conditions?) and nothing happens when you change the calibration constant.

The specifics of his installation can be better described by Jakob (including mcd/mct dump, and firmware). Essentially there is an adapter harness, and grounds look alright.
