Have witnessed shocking mpg and realised my converted car hasn't had the coolant temp sensor wired in just wondering if anyone can help me just wondering how I would wore it in I'm using the mk4 agu management, just wondering what ecu pin I would wire to ect
Thanks for your help, also what else could cause terrible mpg?
-
Right I know it's pin 53 on the ecu so if I run a wire from there to the sensor where would I run the other wore to as I don't really understand the wiring diagram, thank you

Im inclined to believe I have wiring issues with the temp sensor as well albeit on my PD130. Does your temperature gauge move at all?
-
it has a dual circuit, one set of terminals will tell the ECU the temperature so it will adjust the mixture to suit and the other gives your gauge its reading

Yeah I know, I was just wondering if he was having the same symptoms as me.
-
mine was running ok although i have no clue where there reading is coming from as i have a coolant temp sensor with no plug in it on the top rad hose from the agu it would just sit at 90 which i was happy with but i was fiddling to sort my lights out and now i have a flashing light on the dash and no reading atall and the mpg has gone to sh!t so i need to know the pin outs so i can trace where the coolant temp sensor wiring is going to, does any one have any info that could help me?, would be greatly appreciated
