Hello all. We have an E67 ECM that is being used with an 08 TBSS motor swap into a Jeep. The last issue we have is the tach signal. We are using the stock jeep cluster and PCM for the gauge, and a conversion box supplied by the manufacture of the swap kit. Our problem is the tach wire. Its been set to the White wire on connector X1, Pin 25. When we looked at the ECM, we found that it was set to serial data, instead of the crank signal that we needed. We set it to Crank, but I think that like the E38, The Tach output will now be on a different pin. What I need is the correct pin location. I have been searching around and have found that on the E38, it is C1, Pin 48. However on the E67, that pin in already in use. Any help would be great. Thanks.
