ECU boost control and electronic boost control

[JimX]

ECU replacements like the Microtech offer boost control via I assume the factory bleed valve. I'm wondering if I should sell my Profec-B controller after I get an ECU replacement that has boost control, or would it go considerably better if I left it in place?

it is worth keeping them separate

cheers

meggala is correct

Alot of aftermarket ECU do have boost controll but have heard there not that great.

Keep it separate & get a new Blitz Dual EBC

AVCR is over rated, its just pretty lookin boost controller.

Depending on how much power you are looking at the SBC-iD with the optional controller can set different boost levels in different gears to reduce wheel spin, monitor temperatures, do 1/4 mile time runs, 0-100 runs, erm voltages, scramble, lots of other things its also got a spedo. It also has an Auto mode which you dial in the PSI that you want and a manual mode.

It has a few different reading that it can display. PSI is the good one, I don't think any other boost controllers display the PSI do they?

I'm happy with just the SBC-iD that I have, it takes a little bit to get the gain right so that it doesn't spike then have to build up again but once you get it right it keeps boost dead flat well within 1/4 of a psi depending on how you are driving. It never goes over the set boost but.

It is important when the unit is in learn mode you give it full stick in first esp and second!

ALSO.

I actually used a 5 pin PS1 type plug (PS2 I tried but was too small) chopped the cord going from the Hand controller to the Control unit and now I can plug in and unplug when I feel, i.e dropping the car off or when getting pulled over by police.

I've also got it rigged up to the old Manual Bleed Hi/Low Boost switch that is down on the center console hidden on the side.

sorry dribbled on a little

Thanks for the advice guys. To keep costs down and not complicate things too much I think I'll just leave the Profec in for now, and wire up the S-AFC that's been sitting in its box since I got it a few weeks ago. I have to pay for part of the respray of my car so I can't really afford any extra expenses right now.

I know that I could almost break even if I sold the S-AFC and Profec (had offers for both already) and bought a new ECU, but it's all a bit too complicated and I might find that I've lost some of the stuff I want on the Profec. Next year I'll probably sell the S-AFC and get a new ECU and keep the Profec.
