Ok guys, bit of an update...
The car is fitted with a superchips race icon piggyback ECU which was spliced into the white/black wire coming from the actual ecu. I am lead to believe that this is the wire to both the Rev counter and the coil pack. It was space connected and the connectors look a bit green, so my thoughts are either :-
A) the terminals are not connecting properly under heat/wet or
B) the piggyback ECU is starting to play up, which I’m not sure is possible?
So, new questions are
1) is it possible for the piggyback ECU to have this intermittent fault? Symptoms are a dead electrical cut to the Rev counter and, I presume, coil pack that can come back as quickly as it went and the temperature gauge maxing out (making me think the MEMS ECU has power to send a signal to the gauge). What I don’t get is why the temp gauge would max out when the Rev counter dies? Wires are on separate circuits as far as I’m aware
2) I have bypassed it for now and the car is running ok in the garage so does it actually do much on an otherwise standard engine (does have a K&N replacement filter (not cone, original) and a 5 speed box) and will I miss it? If not I will solder the white/black wire back together and do away with it :)
Cheers in advance
