this will remove the over boost safety that the map sensor is used for, this means if you over boost for any reason it might cause major engine damage.
the ecu can NOT adapt afr under full load. The ecu is not adjusting injector pulse width off the primary o2 sensor voltage at this point. Also the lower load value will result in an incorrect base timing value that the ecu may not be able to compensate for.

wondered why my nuts were hanging so low lately, i looked down, HEY KARL!
There is nothing wrong with this method. I stand by what i have said 100 times already. Im not buying a chip for my stock turbo when i go back to BT. Makes no sense.

if you have a chip you dont need to do this. This is a chip alternative. If you have a chip just up the boost to 20psi and your good.

bleed/gated valve will be the smoothest. A combonation ball and spring w/ a bleed valve is a little more but well worth it for a mbc (what i use, turboXS hpbc)

Which boost controller do you recommend Cincy?
please do something other than just slap on a mbc with you chip. if you up the boost like 1 maybe 2 pounds your ecu should be able to compensate for that. but the APR software is not as easily tweakable as other tuner's like GIAC. try to moniter air/fuel ratio. be it installing a wideband, or logging fuel trims with VAG-COM. lemmiwinks is your friend!

Dont know why you say that. The car can easily compinsate fueling with a chip and 18-22psi.

and you know this because you have a chip??
ya, didn't think so..
but maybe you want to pull up some 3 year old Vortex threads where a Volkswagen's APR'd ecu did compensate for it.. be my guest

in fact, i know specifically of a kid with a 2001 1.8t with GIAC ko3 software. he is running at 22psi(don't ask me why) with mbc AND diode mod.
most inportant part is that he has a Zeitonex-sp?- wideband and made a couple fueling tweaks with lemmiwinks

The ecu will compensate fuel trims withen a spec range. Your friend used a 4.7v diode and limited boost seen by the ecu to 17psi and then ran 5additional psi.
Mine has compensated seeing 11psi and running 19-20psi with no fueling problems whatsoever

if you and the mod feel that, that would be the best solution and best benefit for the thread and it's purposes. then yes, by all means..
this guy's car definately isn't going to blow, im just trying to get this guys car to run tip top to it's potential. not just sub par like im sure yours is running..
it's best to educate the noobs the best way possible as soon as possible. otherwise there is going to be that one idiot that's going to put a BT on his car and say, "i can probably just use the diode mode w/ stock injectors and turn the boost up to 22 psi" then KABOOM!!!! [/exaggerated example]

Well since i said in the first post that it should be limited to 16-18psi, i would hope that people would take that into consideration. But you and i both know you cant fix stupid.
A/F should always be monitored when doing anything major to your car, and yes i think something like this is major. For those that dont have access to a vag cable should still know that they are in a safe range and shouldnt fear about causing harm to there engine.
You and your boy Karl act like its going to blow in the matter of mins. As i stated in my original thread, this is/was a temp solution until i replace my BT setup.

get a wideband afr gauge. something like zietronix will be great.

with a chip, 18-22psi is fine. Anything above that and the turbo out of effeciency range

i'm shopping for a boost gauge and am most likely going to try this diode mod.
0-25psi gauge should be efficient i assume, as i have no plans for a BT
correct?
