As above, can the TT fall into safety boost with the stock boost controller solenoids disconnected?? (using electronic boost controller)

Safety boost has two parts to it, one reduction of the boost level, so hence with them disconnected the level would be lower at around 5.5psi however with a boost controller fitted this would be of no consequence.

 

However the second part of safety boost is ignition timing retardation, if the det sensor circuit failed or was correctly activated by detonation the timing would be retarded until such time the fault is cleared or the engine switched off, the boost would remain the same though.

If by passing the Det sensor with a resistor doesn't stop the fault code what else needs to be done to stop the Det sensor fault coming up Jeff?

If the resistor mod hasnt cleared your det sense problem, i would look at the wiring from the det sense plug to the ECU. In fact better to do the resistor mod at the ECU, thus bypassing any problem the loom might have.

I'd be scared to start baring wires at the ECU as there's that many lol. Is there a guide to by-passing it at the ECU mate?

You need to link pin 23 and 50 with the resistor, so better off with the resistor soldered to 2 lengths of wire, making it easier to get a contact.

Cheers mate but it still doesn't look fun especially seeing as I have the boost controller and AFC already tapped into the ECU lol. I'll give it a look tho and see if I can manage it :)

If you have a multimeter, use some extra wire and do a continuity test between the det plug to the ecu and those pins on the ecu. You can at least see if the loom has a break.

Make sure your bypassing the det sensor on the correct side eg the wire that goes to the loom not the wire leading to the sensor! Easy mistake also there are a few similar plugs in that area make sure u got the right one !! Sorry if this sound like the obvious but I'm sure someone could get it mixed up.
