There is a electronic boost control with map sensor available.
The vendor sells also MAF kit's.
This brings up two questions:
Why having two sensors when map can do both?
Is a dual porte wastegate needed in order to have a benefit from that device?

Any exlpenation appreciated.

kind regards

I believe you got the MAP and MAF mixed up.

(anyone correct me if i am mistaken here)....

ALL electronic boost controllers come with a boost solonoid (otherwise known as the MAP sensor), that is the actual little device that measures the boost using MAP (pressure) and limits/controlls boost with youre input (you're settings).

A MAP intake system (such as the Link AFM or a standalone using MAP based) get's rid of the AFM (air flow meter) and converts the pressure at the manifold to create a 0-5v signal that the DME could read.

You would STILL use the EBC's MAP sensor since you wish to control the boost (yes, you would have two sensors, one for the intake to measure airflow for the DME, and one for boost control).

Same applies for MAF set-ups (except they measure air flow opposed to manifold pressure).

Although electronic boost controllers come with a pressure sensor, unless you have the electronics to manage the fuel/timing based on the signal from that pressure sensor, you will still need some other way to measure the air entering the system, such as the stock air flow meter, or a MAF system, or a full MAP system. The pressure sensor is only one part of a MAP system. Typical electronic boost controllers don't have the electronics necessary to control fuel and timing. I cannot tell from your message whether this system includes a full MAP fuel/timing set up, but suspect not if a MAF is also suggested. What kind/model controller is it?

I ran my stock singal port wastegate with the Profec B electronic boost controller successfully. A modern electronic boost controller should work with a singal or dual port, but which controller is it? At any rate, many stock wastegates are too old and weak and tend to leak under higher pressures. For that reason alone, a new dual port is never a waste of money in my opinion.

Vitesse sells it - I don't know the brand.
But thank you guys!

If I get it rigth with a full map system like GURU or Promax there would be no need to have an extra map sensor.

1) clearly you don't understand how this setup is being used, why don't you contact the vendor in question and let him explain it to you rather than making incorrect assumptions here.

2) the "map sensor" in question here is a pressure sensor used to determine boost levels for the electronic boost control. that's all it does, if you buy an EBC with a built in boost gauge it would have a built in map sensor. if you buy the zeitronix wb kit with the boost monitoring option it has a map sensor. if you do boost based water injection you need a map sensor. etc, etc. there is nothing unusual about this.

Then that is the SMT6, used in MAF cars, you could control boost with the boost sensor (as shaheed mentioned, using the soloniod/MAP).

I did contact the vendor - but no reply..

shaheed

then i apologize for making an incorrect assumption myself....hopefully he'll get back to you soon.

When??? Please resend your email.. Obviously I didn't get it as I reply to all of my emails...

pieball

You do? Check it now please.

special tool

I am getting suspicious of your motives, Turbinek.

fast951

I haven't received a thing. Which email are you sending it to? Try info@vitesseracing.com

Black Arrow

Yes he does! And within minutes I might add!

Anyway, to controll the boost with the SMT6 do we need to hook up the computer to change boost? Or is it a "standalone" variable boost controller? I`ve understand that we need some device connected to the SMT6 to controll the boost, right?

pieball

I sent it again, let me know if you're interested or not. If you're not, then I'm not and I'll pass on the unit. Thanks

you need to hook the map sensor and boost solenoid to the smt6, then you can adjust it, log it etc from smt6win. you can also program it to do rpm based boost (ie lower boost at lower rpms to avoid wheelspin).
