Boost control on PRC ecu

Guys,

I'm using a PRC ecu with a V2 Kpro installed. We installed a boost solenoid and wired the signal wire to B21 as stated in the help files, but the solenoid doesn't appear to be getting a signal to turn on and off. Does the PRC ecu have the circuitry to accommodate this? Asking because I had a problem with nitrous control on the E21 pin, where the PRC ecu doesn't have the circuitry for it.

Thanks.

B21 does work on a PRC ECU for boost control. Where do you have the other wire for the solenoid attached?

We spliced the b21 wire and connected it to one wire of the solenoid. The other solenoid wire went to power. Also tried setting the solenoid to a fixed duty cycle, which the logs confirmed was set, but nothing. The frequency was also set as well.

Also tested the solenoid separately to confirm it was functioning.

Post the calibration as well as the datalog showing it not working

I'll have to do another dyno run because we didn't save the logs. When I do this I'll upload.

Also can the b21 wire be spliced or does it have to be cut and joined only to the solenoid wire?

It must be cut and joined.

Ok well we spliced ours. I'll have to cut and join it then. Any reason why a splice won't work?

It cannot be hooked up to the original item it was wired to, it will interfere with the readings.

Ok thanks I will check this tomorrow and let you know.
