Strange reading when logging 12P

Post by Charlescrown »

The first thing is the scaled map voltage shows 5 volts KOEO when it is actually 1.6 being a 3 bar map sensor.
Please have a look at my log and if anyone can explain why the injector BPW is going to zero. It's very noticeable after 1 min 58.
I have tried another ECU and memcal but nothing makes a difference.

Can't work out how to put up both XDL and ADX

so heres the XDL

Problem fixed. After a lot of frustration a call from kojab resolved the problem. No shielding on the inductive trigger wiring. The wiring was replaced and the shielding earthed and it hasn't missed a beat in a couple of weeks and the idle can be set as low as 600rpm with no issues. I must have pushed the coil HT lead close to the wiring when I put in a new battery.
