tuning and boost controller ?

[Jeff@Slowboy]

Got the wideband in today and did some runs to tune. I DO NOT have the 255 fuel pump or AFPR in yet. And it consitsantly like 9:1. with settings at like -23% across the board. Also how should I have the mbc hooked up right now im running unlimited boost and cant get that straightend out. What are we doing wrong.

depends on the type of boost controller.
If its a bleeder valve design then you have it backwards.
hookup is as follows.
one hose from the boost source (turbo) to the left side of a T connector (this hose should have the pill installed in it. The pill is a metal piece with a small hole drilled in its center. This limits the quantity of air ran thur the hose.)
One hose from the actuator to the bottom of the T connector.
One hose from the right of the T connector to the input adapter on the boost controller.
The boost controller output is then run to your intake pipe.
THIS IS ONLY FOR A BLEEDER STYLE BOOST CONTROLLER.

For a normal boost controller you just plumb it up inbetween the boost source and the actuator. No T connectors, no B.S. just one hose in, one hose out. If its not working, swap the hoses around.
If its still not providing enough boost to actuate the wastegate then you might want to pick up another one. In the mean time run a hose from the boost source to the actuator to keep you safe.

As far as your AFR is, 9.1 is rich as hell. what fuel controller are you using?

Im running the turbo xs mbc, and Im using the afc, isnt 9.1 way to rich for just 650s and stock pump and stock fpr?

Manual boost controller hooks up to a vaccum source and a the vacuum off the wastegate flapper (on top). Then you turn the boost up w/ an allen key on the top for that type of boost controller

You may have a problem with something else, and that being the reason you're running rich.

I also have the Standard Turbo XS MBC. I plumbed mine without the T connector and it works perfectly.

 

[Jeff@Slowboy]

Any Ideas. All i need to know is the brass fittin on the mbc does tha have the line to the wastegate or does that have a boost source line hooked up to it

 

[delta448]

WGA side to blue (or silver) bottom nipple, Compressor side to brass side nipple.

Thats what I needed to know, which vacuum line went where, thanks Delta.

We just ordered an FPR kit from fuel injector clinic so tuning should be better once that gets in
