Does anyone have an MPEM compatibility list? In the past I've installed a 2005 MEPM in my old 2002 ski and it worked great (until it failed last week); the only difference I noticed is the buzzer would beep 4 times in rapid succession instead of twice and "Sensor" would flash in the information center because the 2002 model didn't have a depth sensor. I see very limited availability on the 2002 part number.
I pulled down the schematic for a 2003 GTX 4-Tec (saw a 2003 MPEM on Ebay) and the electronics are identical between the normally aspirated engine and the supercharged model, and there is only one part number listed for both types of engines. The only difference between the 2003 and the 2002 is there is one more wire between the ECU and the diagnostic port and another wire going from the diagnostic port to the MPEM.
ECU B24 to Diagnostic port Pin 6
Diagnostic port Pin 4 to MPEM 1-5
There are no details on the schematic for the purpose of these two wires, but the other four connections between the diagnostic port and the MEPM are identical.
MPEMs are getting harder and harder to find and Ebayers know it because the prices are crazy!
