Gonna look into trading up to a M-48. I cannot control my voost soleniod as I have used my 4 outputs already 3 ignition and 1 for fuel pump.



Hmmm.. I wonder If I could control the fuel pump independantly. I am usinf the stock FC relays. I will have to research this better.



But for right now I cannot use the boost cotroler.



I am seriously considering doing a manual boost controler. I am sick of this already.

I just E-mailed Jay from Motec to see if I am missing something.



I have a MBC. I have not put it in as I have just been letting the wastegate do all the work. It boosts from 7 to 10 psi as the rpms go up. I am puting 320 to the wheels like that but want to boost to 1 bar so I guess I will be setting up my MBC.



The Motec BC is very cool. I can have the boost change with RPM's like I can set 10 PSI down low and have 15 PSI from 4 to 7 K then drop it off as the rPMS near 9.5K so I will not put an unnecessry strain on the engine.

Why not an electronic boost controller?



They make it easier to turn the boost down on the fly, say if you're having traction problems at autocross or on the track. I'm set up to use my ECU for boost control as well, but to change any setting I'll have to use my laptop. https://www.nopistons.com/forums/pub..._DIR#>/sad.png
