Does an EBCS need a tune?

When installing a 3 port EBCS, you will need a custom tune. Because the 3 Port EBCS operates so much more efficiently, without tuning, your car could over boost running factory targets.

Do you need a tune for a boost controller WRX?

Yes, the ECU will need to be recalibrated for any change made to the factory boost controller.

Do you need a tune for boost controller?

NOTE: You MUST run a boost gauge to properly tune the Manual Boost Controller. Raising your boost level may destroy your engine if you raise it too high without proper tuning. Our boost controller works by interrupting the pressure seen by the wastegate.

Do you need a tune for external wastegate WRX?

For External Use Only You’ll need a tune and an EBCS for an EWG.

What does a boost controller do WRX?

Subaru employees a bleed-type boost control system (as opposed to an interrupt type) for controlling the internal wastegate systems. The logic present in the Subaru ECU is capable of tuning either internally or externally wastegated systems as long as they are properly set up.

What is EBCS Subaru?

The Cobb 3 port EBCS “electronic boost control solenoid” is one of the first mods we recommend for any 02-07 WRX or STI. While the factory EBCS works ok at stock boost pressure it is not able to keep up at higher boost pressures. Works with both internal and external waste gates for stock or aftermarket turbos.

What happens with too much boost?

Increasing boost (within reason) will force more air into the engine, so more fuel can be added to increase the power. So in general, if you add more boost and have an engine tuned to suit will give you more power. Too much boost can cause turbo or engine failure.

Does a wastegate add horsepower?

A wastegate is possibly the only component in your whole engine package that can actually be made smaller as you increase your boost/horsepower output – in certain circumstances. An external wastegate is used to drive exhaust gasses away from the turbocharger to regulate turbine speeds and therefore boost pressure.

Does a wastegate require a tune?

Yes, you need a tune.

What is boost creep?

“Boost creep is a condition of rising boost levels past what the predetermined level has been set at. Boost creep is caused by a fully opened Wastegate(s) not being able to flow enough exhaust to bypass the housing via the Wastegate(s) itself.

What is stock boost on a 2002 WRX?

Pretty sure stock boost is 14.7, but you can’t hit it until 3d or 4th gear.

What does a boost controller do on a WRX?

What do you need to know about grimmspeed solenoid?

Unlike your OEM 2-port solenoid, the GrimmSpeed BCS will allow for extremely high resolution boost control, providing your tuner with the hardware he needs to safely tune your car with rock solid boost levels. Using our solenoid, you are able to spool your turbo quicker and maintain tight control of boost levels throughout your power curve.

Where is the boost port on a grimmspeed 3?

Port 3 connects to a high-pressure boost source (there is a vacuum nipple on the turbo compressor outlet). Port 2 connects to the internal wastegate actuator vacuum nipple and Port 1 should be routed back to the intake (where the factory BCS mounts). The factory restrictor pill can be removed for operation.

Where is the boost solenoid on a WRX?

Installation for 2002-2005 WRX and 2004-2005 STI:Remove cover on passenger side engine bay exposing the factory boost control solenoid. Using a 10mm socket, remove factory solenoid and unplug the electrical connector and vacuum lines. Reuse the factory rubber mounts and transfer them to the GrimmSpeed bracket.
