We are developing a ECU-based closed loop boost control for the evos and have been doing some R&D in the last week on my personal EVO 8.
So far the data is great and I am really excited with the results.
One of the biggest problems with the stock boost control solenoid on the EVO is that, even tuned with different pills, the response and spool rate was always behind a good MBC.
With our new ECU-based boost control, we keep all the factory safe-guards but lose all the factory shortcomings mentioned above. Lightning fast spool, even better than a MBC so far in our testing!, fast response that the stock solenoid cannot match and the ability to custom tailor the boost curve with complete control.
The other great benefit of this system is for people that want to run separate 91 octane tunes and race gas tunes. No more having to pop the hood and twist the MBC to up the boost for the race gas tune and hope that you set it right. Now this is fully controlled by the ecu reflash. Reflash your 91 octane tune to your race gas tune and your boost is set already. Reflash back to your 91 octane tune and your boost is reset to your 91 octane tune.
Here is a comparison between a MBC and our new ECU-based boost control:
(Test run is our new boost control, Base Run is MBC)

Ignition timing was not changed, AFR was changed to match the MBC tune. (11.5 AFR on 100 octane)
Expect more news soon as we continue to develop this!
