Hi guys,

I bought a Profec B boost controller, my car has non-sequential turbos -Pettit hybrid hi flow twins-. I installed the boost controller the last weekend, but it does not controls my wild boost, nothing happend.
I check the connections, the hoses and everything seems to be ok. There is no difference in the boost behavior, turning the unit on or turning it off, or moving the *****, just nothing happend.


I put the hose that was connected from the turbos to the IN on the Greddy solenoid box and the OUT from the solenoid box to the wastegate. The solenoid box is a bridge between the turbos and the wategate.

Can the profect B control the boost even if my turbos are non-sequential?

Is my wastegate actuator bad?

Well, I will appreciate your help.


Thanx,

My car:

*1993 RX-7
*Pettit 3mm street ported engine.
*Pettit Hybrid high-flow turbos.
*Pettit Unlimited ECU.
*DP
*MP
*No cat
*No pre-cat
*Free flow resonator.
*J&S knock sensor.
*Aluminium fly-wheel
and some extra gauges, temp,boost,a/f.

 

Yes the profec b can control your turbos.

Sounds like your wastegate actuator could be bad. Are you getting way to much boost? Also, did you cap off the other line going out of the actuator?

 

Yes, the other line is disconnected, no hose there.

I will check the wastegate.

Thanx a lot.
