Gizzmo Ibc

[jap32r]

hi all i was needing some help setting up my gizzmo ibc i done a search on this topic and found some helpful tips but it still don't work so has anybody else got one of these and know how to set up boost pressure.

from i can understand on the instructions it say i gotta hold the desired boost for half a second so that it stores in the memory of the ibc, that sounds kinda wrong to me.

any help would be greatley appreciated

yeh i need help with that to 2, coz the instructions it is not very clear and dosen't seem to work.

What issue are you having with it, installing or actually setting the desired boost level?

There are 2 settings, duty cycle (boost level) and gain response.

To set boost level:

Hold top button for 5 secs, enter desired level (start low), say 18 (note this does not mean 18psi).

Once its set, dont touch any buttons for 5secs, you'll then here the solenoid ticking, at this stage you need to drive the car in a spirited fashion under load and then see what the boost reached.

If not happy with the boost level then start the cycle again gradually raising the duty cycle.

This is what I had to do with mine, not sure if the newer model has changed.

But I had to drive the car to set boost, as the fuzzy logic learns your turbo setup.

To set gain response is the same as above, but hold the bottom button.

thanks bud i'll give it a go see what happens, at 18 what was the boost level?

[Anquetil]

I cant remember mate. But it will be minimal boost, just start off low then test drive, you'll get your head around how it works.

I think mine is at around 60 duty now, which is 14-16PSI.

And gain is 6.5

All cars will vary though.

I noticed there are new manuals for the IBC, the new one does not mention the ticking solenoid opening and having test to drive under load to set boost pressure.

OK well I have one, and just about know the full ins and outs on this thing, have been stuffing with it for about 6 months.

Ok the way the controller works is to set a desired solenoid duty, this is how fast it opens and closes, the higher the number the higher the boost.

HOWEVER the number does not relate to boost directly. For example, 14 duty, does not mean 14 psi.

The controller is limited to what gate you have. If the stock gate is preset to 7psi, lowest setting you can run is 7 psi.

The way to preset the controller is as such.

Find a nice stretch of road, LONG and 100kph plus.

1) Hold down the top button for 5 seconds. Once this happens it will flash the number to preset the duty. For an R33, 10psi is about 45 duty, but this differs.

2)press down on the top button until the desired duty number is reached. START with 10.

3) After the duty has been preset, wait 5 seconds until the IBC goes back to monitor mode.

4) Once in monitor mode, take the car for a run, you need to load the car up good, so a WOT run in 2 and 3 will do, but you will go wayyy over 100kph so be careful. While accelerating keep an eye out on the boost to make sure you don't over boost.

5) after the run, press the controller top button, this will go to setting 2 for boost, then press the down button to go back to the previous boost setting. This will display the maximum boost reached.

6) If the boost reached is low 7psi, increase the duty of the solenoid, and then go for another run. Continue to do so until you reach the desired boost level.

Repeat step 1 onwards again.

7) If you want do this for 4 different setting. Just as an EXAMPLE on my car with all the mods listed, following duty corresponds to each boost 25=8psi, 35=10psi, 49=12psi, 67=14.5psi.

NOW once you get the duty set, it's time to set the response. This sets how fast you build boost, too much and you will over boost, tooooo little and it will be laggy.

1) Select the desired boost memory to work on.

2) Hold down the bottom button for 5 seconds

3) Once in the setting mode, increase the number. Start low say 5 and go from there. The higher the number the faster the boost will build.

HOWEVER

The number depends on boost reached. At 7 psi you will need a higher number to build fast boost, as the turbo is not very efficient at this low boost. So for example at 7 psi the response might be 30 but at 14 psi it will be 2.

If you set the response too high, the car will surge, the boost will rise and drop VERY fast, back off on the response for that particular boost setting.

HOWEVER if you have a mismatched wastage, and you have boost creep, you can minimize this by allowing some over boost on the controller. So what you do is set the response higher, so that the turbo over boosts, but by the time the IBC has reacted the wastage creep has caught up and boost remains steady.

IF you have BAD CREEP issues, reduce the DUTY of the solenoid by 4, and increase the RESPONCE by 2 or so. This will allow for some moor creep control by intentionally over boosting the initial boost setting.

Basically you want to set the response in such a way, that the gate opens 1 psi before the desired boost is reached, this can only be done by trial and error.

WHEN setting the response, you do not need to go for a drive and boot it, it will work itself out during normal driving.

SO I hope this covers it. HIHIHIHI

If anyone has any question PM me, I don't know if there are many people that have as much experience as me. I really went to town on this thing, as far as getting the functional description from the manufacturer to see how the thing works. LOL.

Forgot to add.

In Cold weather, you will have to reset the duty, colder air easier to compress, hence higher boost setting will occur, as the boost controller always monitor boost settings, so if you preset it to 12 psi, but on a cold night reach 13psi, it will always then try to go to 13 psi.

This is same for most controllers, which sux. BUT i found the gizzmo works well, sure it has it's downfalls, mainly that the boost can change depending on temperature, but it is fast, easy to use, well once you know how to and has great closed loop controll.

Same goes for hot eather, hot weather means harder to build boost, so lower boost.

[Anquetil]

Lol! Dude thats what I said.

[WogsRus]

I know just being a bit clearer

[jap32r]

hi all tried everything you guys explained, but i came to realise that even with both the duty and gain at minimum i'm still hitting 19.2psi and that's with me backing off when i see how high it's going, i'm wondering if maybe the solonoid isn't working i'm hoping anyway so i can take it back for a refund, anyway if anyone knows any other reason why it is not doing it's job please let me know.

thanks all.

[WogsRus]

no if the selenoid was stuffed, IE in the open position, then you would only get what ever boost the wastgate can hold. on an internal gate. Not sure externally.

I must admit my first controller i recived was stuffed, had a bad solder as it didn't always controll boost. LOL>

Might be a falut, but i have never used the gizzmo on an external gate.

[jap32r]

someone told me that the spring on the external gate might be to tight could that be the problem.

I might take it back to the guy who installed it see what he thinks

[WogsRus]

yepp if teh spring is to tingh, that would couse teh boost to be preset to the spring rate.

thanks for all your help bro,
