Hi there, i bought the EBCS boost solenoid a few weeks ago and had it fitted by a tuner the other day.

They fitted a MAP sensor at the same time.

All to my Power FC unit on my Evo 7.

It all works but at high boost it pulses and fluctuates up and down +/- 0.3 bar

It is set to peak at 1.45 bar and goes up and down from there.

The tuners said it was OK but the solenoid is running a different hertz to the power FC and i should use the Apexi solenoid to cure the problem.

So, what can you do to help???

What is wrong with using the EBCS with the power FC unit?

Can i fix the up and down boost thing?

Please help.

Thanks

Bill.
