Ha. Thirsty beast this.
I think because I linked the 2 sender wires, the fuel tank reading is roughly right. It never reaches 100% full on the ecu strangely. Maxes put at 92%.

As soon as the gauge passes 3/4 it drains rapidly

All done and wired up.
Got 1.5 bar at idle which seems OK. I've dropped the idle back to standard from 1k.

Just check that idle oil pressure when oil at 80deg c and above. Pressure drops as it warms and thins.

Think I found the reason why the dsc was kicking in unannounced. The passenger side sensor was slightly further away from the abs ring than the drivers. Closed the gap up now and see how it goes
