Blitz Dsbc

[R32Abuser]

Hi all,

i have just installed a Blitz DSBC (Silver casing and blue back lit screen). Got it put on the duyno and have found out my fuel pump has had it....

Was driving home today and put my foot down a little and it seemed to do the misfire thing (as this is an Bosch fuel pump that just kacked it) (not sure whether its not flowing enough orhas shat itself) anyway it seemed to do that boxer engine type noise but along with a bit of a "chirpy" type noise as if it wsa coming from the turbo.....Decided to limp it home safely....

Im wondering whether it has been set up with too much boost and its just leaning out with this pump. That sed is someone able to tell me how to setup my boost controller so it runs as little boost as possible..possibly supplying a phone number?

Or do you think it may be that from the addition of this controller then boost is coming on stronger than before i.e. more earlier causing a misfire earlier or....????

Any help is greatly appreciated.

Cheers David

Turn the boost controller off. That way it defaults to your actuator pressure only. That's the lowest boost you can run without modifying anything.

I tried moving it to off mode...did that... this but it would still register boost and if i put my foot down it would boost to like 1.3 bar

which is not to health for my stock turbo

and now im scared if i do try it again it will blow the turbo!!! help!!

Then it's probably been installed wrong. What boost did the car make prior to installation of the dsbc? Check the little switch on the back of the unit is set to "ac" and not "wg". The stock 32 actuator should make a maximum of maybe 12psi before dropping back to 10.

Made like 11 psi with tapering back to 9 or so in the higher rpm....however as the fuel pump was f**ked she was running a litle lean....(12.9)......but that was without the boost controller installed when she went on hte dyno......ill check that....but not sure i kno what i am doing....instead of trying to stuff around with it to much...shud i just leave it and just baby it until i get it all tuned and a ne wfuel pump done??

[R32Abuser]

did that wc and ag thing and it was on wc and changed it to ac and i think it has worked..... however i set my warn for 0.80 bar and it still goes off....i was wondering what 0.80 bar would be in psi?

[Links]

do 0.8 *14.7 = it's about 11psi..

so.. yeah.. could still be pushing higher than that.. what does it peak at?

[R32Abuser]

sorted it out now...but trying to keeep a lower boost as i dont think the fuel pump is up to the job...and my fuel ratio are already to lean...

Cheers for the help phellas....
