I've just fitted a Blitz Dual SBC Spec S onto MY98 UK turbo. Disconnected the pipe from the compressor into valve unit in, and actuator to valve unit out, leaving T piece to the original solenoid valve plugged in.

Went on a drive, but there is no reading on the unit at all. Have I connected it wrong? Should I have disconnected the original solenoid and bung it up? If so, at what point should I disconnect?
Your help would be much appreciated.

 

The last blitz SBC I fitted had 3 pnematic connectors - One connected to the turbo outlet nipple, the other connected to the wastegate actuator nipple and the other to the inlet manifold to measure the boost pressure. The original boost solenoid still needs to be electrically connected but pneumaticalliy blanked.


Cheers

 

Excellent. I'll have a go tonight again. Thanks Delboy
