Boost Control Setup Issues - Thunder ecu


Recommended Posts

Link Thunder ecu, trying to setup a 4 port mac valve to control boost, wired into AUX 6 and set as Boost Solenoid.

- Tested pwm, pulses solenoid and can hear it, test off it stops.

- See log below, last pulled i logged, WG Duty is working as commanded in table but still only seeing gate pressure being about 12-13psi.

- Boost Solenoid pulses with ignition key on for about 4-5 secs and then stops without touching key, is this normal? Even thought we have no duty at "0" MAP in the boost table.

- Triple checked plumbing to wastegate, all correct and tight.


Any help would be much appreciated, car was running an Eboost and with same solenoid and was perfect operation, have made no changes apart from wiring in mac valve to ecu.
