Normally have my boost limit set to .88 lowest i managed to get it set to.
Fitted new coil packs today to try and sort out my misfire at 5k , i then went for a spin was giving it a bit of beans as wanted to see if new coil packs had sorted my misfire and they had and noticed my controler flash up at .92 and now has that stored as the set boost.
I have tryed to set it lower now but cant get it any lower than .91 is there anyway i can lower it to .85 and set it there so it wont change again
cheers lee

Hope ths helps :)

Setting a Gizzmo IBC - The (VERY) Simple Guide

1) Fit Unit as per instructions

2) Start car and allow engine to warm up thoroughly whilst doing the next few steps

3) Press the top button on the IBC until the no. "1" is shown on the display. It will flash 3 things: "1(The boost level)", "Target Boost(whatever that is)", "0.00(Real time boost level)".

4) Press and hold the top button until a number (The "duty cycle") comes up on the screen. Set this to 10 (the minimum).

5) Leave the controller for 4-5 seconds and it will return to the "real time" boost level

6) Press and hold the bottom button until a number (The "gain") comes up on the screen. Set this to "0" for the moment. Leave for 4-5 seconds until it returns to the "real time" boost level.

7) Drive the car on full throttle in 3rd or 4th gear.

8) Pull over to the side of the road in a safe place, then either turn off the ignition then turn it back on again, OR, Press the top button once, then the bottom button once (this will put the controller into boost level 2, then back to 1 again). Either way you do this you will be informed what the highest stable boost pressure achieved was by way of the pressure flashing at you on the screen. This is the new "Target" boost. Let us say that this was 12.5psi and you would like to achieve 16psi.

9) Press and hold the top button again until the "Duty" comes up again. Increase this by 10. Then leave the controller for 4-5 seconds until it returns to the real time boost screen.

10) Repeat steps 7/8/9 until the boost level you require is achieved. If you get duty cycle over 50 and the boost level is not increasing, then you have either not plugged in the solenoid or you have not plumbed it in correctly! As it gets closer to the level you would like, only increase by small steps of, say, 5 at a time.

11) When you are happy with the pressure, press and hold the bottom button and enter the "Gain" setting menu. Gain is How hard/fast the boost is brought in. It should NEVER be higher than duty cycle. In fact we have found the best setting is below 10. If gain is too high the boost will either overshoot, or the maximum stable (Target) boost will increase every time you drive it!

12) Repeat steps 3-11 on boost levels 2, 3 and 4 to achieve the boost levels you require.

It's extremely simple to do and the controller gives consistent, steady results if this is followed.

The Gizzmo unit will memorise the highest stable boost it achieved for the given duty and gain settings for each memory slot. It's because it does not work like other BC's where you input the desired boost level... it works on duty and gain. The reason it probably flashed and memorised 0.92 is because it's very cold out there. If you have the MS-IBC model I would recommend you running in closed loop mode.

Yes ms ibc is what i have how do i put it in closed loop mode cant find my instruction book and how do i lower the boost setting using the duty and gain?

Ok ill try that and isnt it .6 bar at actuator for gtst.
I have just been told that there were few faulty in the first batch of ms-ibc them not keeping the boost setting like mine and gizzmo are replacing them
so that could be why mine allowed its self to boost to more than what it was set to and then store the new setting.

Who told you that? Mine behaves the same way as yours, I thought it was normal if the gain is set too high?

Ive just been emailing gizzmo and been told to turn the gain down they were actually quite rude in one of the emails but wont go into that.
So im going to try and turn the gain down and see if that solves my problem.
