Blitz boost controller problems Options

[donna]

Hi all

Can anyone tell me how to set up a Blitz SBC-ID single solenoid?

I had mine installed yesterday into my st205.The person that installed it has set it up roughly with the following settings:

Gain 5
Boost pressure 15 psi
Warning limiter 16psi with a limit of 8

This all seemed well and good and i was getting a steady boost of 14.7 psi.I decided to give it a bit of beef and the boost pressure held upto 4 gear but when i put it in 5 gear i felt a big surge of power and then it dropped straight of(which scared the hell out of me lol).The controller went into limit mode because the boost had risen to 20.4 psi,should this of happened?

I would be greatful of any advice as i am completly new to all of this.

The car i have is a 96 st205,standard internals.No other major mods

Hello donna

I think you should ask a professional to do this for you.
You are using ST205 standard ECU or aftermarket?

It was fitted by Millway in Andover,if you had heard of them.So it was done professionaly.
I think the ECU is the ST205 standard one.

No need for any kind of professional to adjust a boost controler.
Have you tried reading the owners manual?

Gain is the response of the turbo. Too much gain will cause boost spikes, not enough gain will cause boost creep.
Try playing around with that until the boost stabilizes.

Thanks for the info,i will have a play round with it later.

not enough gain will cause boost creep.

How do you work that one out??? Not enough gain will just mean that your turbo is under performing and slow to respond...it wont cause it to creep

i think what he meant was that it will creep up to your desired boost.

donna, when you set boost, you should always test it in 4th and or 5th gear,@ WOT, with full load on the engine.
if you set it up and get 15psi in 1-2-3 gear, it will creep up higher in 4th and 5th when there is more load on the engine.

Like presure2 said, it will creep up to where you have your SET setting, instead of hitting that boost right away, but if you use too much Gain, then the boost will spike.
It states this in the owners manual.

OK...just thought I`d check as "boost creep" is something altogether different.

Cheers for the info.My plan was to play with the gain this weekend but it looks like the car is back in the garage.When i was driving home tonight there was loads of steam coming from the engine bay and it looks like the top of my radiator has split
