Hi all

Have a quick question re the 14cux. Fitted 3.9 with lt77 in Mgb gt, been on carb it’s now on injection off RR.

Had it running but wouldn’t idle unless I popped a washer under the idle stop on the plenum, but it warmed up and would restart etc

Anyway, one question is roverguage shows a fault that it’s in rev/drive? I have fitted a 510ohm resistor to ground on the orange and black wire, but still reading it as an auto.

Secondly is the inability to start on tickover due to 3% throttle position (without washer) and my maf voltage 1:25v which is low?

Thoughts greatfully recieved

I will be putting the chip upgrade in from mark at blitzracing (4.0 tvr non cat) but wanted to get initial gremlins ironed out first.

Check the resistance at the ECU harness connector, could be that the terminal isn't making good contact. The terminals are basic hairpin type and prone to deformation so don't go prodding into them with the multimeter probe, just touch to the curled bit.

Have you the road speed sensor connected, I seem to remember this type of fault is caused by not using the sensor.
