Sorry, are you using an external waste gate with the standard ECU?

If you have an external wastegate you will have problems. It's not designed to run one, as it's supposed to be a recirculating type. If you want the noise an external wastegate gives you, buy a forge split R.

Are you talking about a diverter valve?



The wastegate is a device built into the turbocharger for regulating the boost.

Some cars run a remote wastegate as the chosen turbo does not have a built in wastegate. An example or this is the ur quattro.

the thing is that if i use external w/gate some of the gases will exit elsewere , so the second oxygen sensor wont read the proper values of air/petrol.so the engine light will be lid. that how im thinking of it and if this sound right doesnt mean than its going to be like that.just guessing. i want to be sure so i wont proceed doing the job and then have my mate breaking my b88ls. thanks guys

What are you using for control of the external wastegate? and why are you using one?

[megane225]

you going to laugh with this one , but my mate wants to make noise and nothing else. im against it but he still wants to do it

External wastegate isn't worth it for that, if he wants to make noise change the exhaust to something silly... I'd you want better control of big boost move to an externalgate and screamer pipe.
