jtd ecu readouts, bad mpg
For the past couple of weeks I have been hunting down the cause for my bad mpg, I have checked egr, cleaned the map, cleaned the maf, full service etc.
I have plugged into the obd ports, and I was wondering if anyone can tell me if any of my values seems wrong at idle, im particuarly concerned with the map one and also the engine load.
Engine load=38 to 45%
Map = 104kpa engine off 105kpa engine at idle
Maf = 14.5 at idle, was 8.9 before clean
Coolant = 90
Revs = 850
Any help would be greatly appreciated I do a 80 mile round trip a day with 74 of them being motorway miles and it wont go above 38 mpg, checked multiple tims with the brim to empty test and it works out at around 36 everytime.
