dremd; True mechanical injection has no electrical input or operation like the Lucas injection (i.e. CanAm 494 Chevy, Formula 5000 Chevy, 1971 Porsche 911E) it has a belt or gear driven pump, throttle linkage controled metering unit, and undividually run high pressure lines to each velocity stack. K-Jetronic is not that type of injection. Mechanical injection has no air density measuring, it is set pretty much on a flow bench or dyno by a tuner or builder. In the case of the street Porsches, this really was true mechanical injection and it was used in a street application till the K-Jetronic injection was interduced. I had one, was really neat injection, nightmare to set up , but ran better than webers (Solexes if stock) and stayed in calibration till you went to a diffrent altitude at which point you had to set it for air density. Once agian K-Jetronic adjusts for this via the air metering unit.
