Hi there - I have reincarnated a dead project, it was a Range Rover Classic (1992) that someone had started converting to a Dakar, I have now got it on the road and running ok but I feel it should be performing better? I have invested in an ECUmate and it has pointed me to a disconnected road speed sensor that has now been rectified (Most of the wiring had been removed leaving only the ECU to injector wiring plus the temperature sensors, everything else had gone!). The car is running a custom exhaust with no cats and a green resistor which should tell the ECU to not look for any lambda's. However the screen shows some interesting results:





The mapping runs lower on the left side consistently lower and it's showing different reading from LamA and LamB?

Any ideas people?

Thanks!

Id suspect you simply have a revision of software that ECUmate is not reading correctly- it wont be a fault. ECUmate (or any other OBD diags) has to read certain memory locations in the ECU to get the data, and these have not always been same- The value simply looks like the location its looking at is empty. ECUmate is a diagnostic tool for fault finding, its not something you can use to tune the engine if the green fuel map is not correct for your Engine tune.

Sit it back and have a read here:
