I'll check this out when I get access to a Modas cable but anyone have any experience with this Motec alarm???
Engine/car runs fine but have to reset the alarm every quite frequently...
Motec reads " ECU DIAG"

thanks

i believe the first or last tab has the error warnings. could be o2 stuff, or anything else, id definately check into that.

Could also be a "simple" Gear potentiometer problem. Try to calibrate it, just in case... (but I don't think that the alarm will go out without a Modas reset)

I had this flag. When I accessed the ECU via the Modus cable, my gear pot was out of cal. Those were the only errors I found in the ECU.

In my team, my car and an other had the Diag light alarm due to O2 sensors, we changed both sensors and had no more alarms ....
