Which FD ECUs have internal boost control. All I currently have is intake, DP, and CB and wont be adding anything accept maybe an intercooler anytime soon.
So it doesn;t have to be too tuneable.


Thanks,

 

AEM Does... Built In,
Power FC, you have to buy an add-on module,
Dunno abot Haltech or Motech

 

So you have to buy an additional unit for the Apexi?

 

No you don't, the PFC controls boost using the stock solenoids. You only need the add-on kit if you are boosting over 16 psi....(or you can just use a GM 3-bar MAP sensor).

CSMCanuck: I would recommend a separate boost controller anyway. There are many advantages and no disadvantages, other than $300 spent and one more little box in your car.

 

isnt motech just a piggy back system, im sure they have a seperate motech boost controller module

 

The Motec is the best engine control computer in the world.....about as far from a piggy back as you can get.

The Electromotive TEC3, Haltech E11, and Motec ECU's also have boost control, but they are not specifically made to plug into the FD like the AEM and Wolf listed above.

The on-board boost controllers generally have better resolution, and in some cases, more functions. Also, that extra money and extra space for the extra box can add up. I think it's best to look at the prices and capabilities of the ECU on-board boost controllers, electronic boost controllers, and manual boost controllers to see what you like best for your particular situation. Most people don't even need a boost controller.

 

True, but in the case of the PFC, you are using the stock solenoids to control boost (unless you buy the add-on kit). I think the Profec does a more consistent job and is easier to tune without all the f*#$king around.

The other ecu's may have better boost control, but I don't have experience with them.

 

Haltech requires a remote solenoid, but you can wire up the stock FD boost solenoid and allow the Haltech to control that.

Haltech allows boost mapping versus RPM and road speed. Newer E11's allow boost mapping versus gears.

To share an experience with the AEM on an MR2, we had a Profec BC attempting to hold 19psi. Regardless of how we adjusted the gain, the boost would fall to 16psi by redline. We were almost certain the problem was caused by backpressure (due to an undersized turbo).

Just for fun, we installed the GM boost control solenoid and controlled it with the AEM. 20psi to redline in every gear was the result.

Not all boost control systems are created equal. In my opinion, the AEM's and several others are a step above the competition. The ability of the Haltech and AEM to control boost versus vehicle speed is awesome and works very well for certain types of racing.

Hope that helps!
