Dakota Digital interferance
I know that I need to contact Dakota Digital for this, and I will tomorrow when they're open. I'm just wondering if anyone else has had interference issues with using their products. Allow me to explain further. I'm running a stock 2004 LQ4 6.0L with a 4L80 transmission as a swap into a 1980 Camaro. I'm using the stock PCM which has it's initial flash from Brenden @ LSI swap. (I just bought the HPVI2 so now I can do this) I bought the HDX series gauges from Dakota Digital. I'm using their BIM-01-2 interface module to run the tach, the engine temperature and the speedometer via the OBD2 connector. (So I cannot connect the VCM scanner while having the BIM-01-2 connected for the gauges. The engine oil pressure isn't supported on the CAN so I had to wire that gauge separate. I'm also using the Rostra cruise control by using the VSS signal off of the PCM. My problems are definitely only occurring when the Dakota Digital BIM-01-2 is plugged into the OBD2 port. I'm getting a "surge of RPM's" that will just randomly happen, sometimes while sitting in park but most of the time while driving. While driving the surge of power or RPM's is enough to cause the transmission to kick down. These power surges are about 3 seconds apart and usually 3 times each episode. The transmission will down-shift each time. When I unplug the BIM-01-02 connector from the OBD2 port these power surges will completely stop and all is well. Again, since I cannot connect the VCM scanner while the OBD2 port is occupied I can't get a scan to send. I have double and triple checked all of my grounds to each of the above components. If anyone has any input I'd love to hear what you have. I neglected to mention that no fault codes are ever logged in the PCM when the "hunting" episodes happen. Thanks.
