Hey guys

First time I've decided to join the page as I actually have a skyline now. Finally.... Only took 20 years

Anyways

Here's my dilemma. Anyone who has the same ebc could really point me in the right direction

Not sure if there are different gizzmo ibc's but I looked up a manual and seems pretty bang on

I have a 32 gtst and its running around 10-11 point on both setting 3 and 4 now these were preset by the last owner

Setting 1 and 2. The first one has no boost pressure flash when you select it (showing max boost). 00.0. So as guessed. It over boosted on these settings I had a fiddle around with the duty cycle (by holding in the top button). No help. Cracked 21 psi at one stage. I know I know. But it's kind of hard to do it while the cars just taking off into the sky's

So I figured ill hold the top button on the 3rd setting (showing 10.8 max. And whilst driving a max of 9.8. Which is odd) and the duty cycle was 10 aswell but no over boost?

Maybe this just shows 10 every time you enter this mode?

Well the 4th setting shows a max of 11psi. I'm getting close to that on te guage. But on the gizzmo says I'm getting around 9.6.

Possibly because the guage may be somewhere else in the engine bay. Which would make sence

And I do notice the pressure drop ever so slightly sometimes (possible leak I guess) remembering I've only owned the car a week cut me some slack I will go over everything when I get the chance.

Also when I hold the bottom button to set the gain. It flashes the 00.0. But neither buttons do anything

So what do you gues think this could be?

Any help is appreciated

And hope to meet you guys soon on a cruise or meet up

Please do not fiddle with the EBC if you're not too sure - unless you want to break the engine (i'm assuming it's stock motor as you haven't mentioned otherwise).
The EBC is displaying a little higher than what you're seeing because that's the highest peak it's ever seen - possibly from the previous owner or yourself driving it one cold night and getting a slight boost spike from the denser/cooler air.

It sounds like only profile 3 and 4 is setup on the ms-ibc so please stick with those profiles.

Yeah I figured. I didn't pump the car etc I'm fairly mechanically minded and have built a couple of cars in the past but I've only ever used mechanical boost tees and the old hpi controller which was adjustable by the knob and worked the same (although it was horrible)

Basically one I seen it pass the 14 mark (where I thought I had boost set. But Aparently I set the duty cycle) I backed off as I knew it would over boost. Also only had it in 4th with hardly any throttle

Haven't touched it since until I can sus it out properly

Anyone on here could direct me in how it works

Or possibly meet somewhere in the campbelltown - Liverpool area ( I'm heading out to Liverpool mega centre Krispy kremes now)

Or a southern highlands person like me

Let me know. Keen to make a few more friends with skylines

Could you rephrase what you wanted to know ? I read your first post again but not entirely sure what you're asking haha (am tired after a long day though hrm).

Things that may help you about this ebc though (yours is the ms-ibc yes?)

If the other profiles haven't been set, you shouldn't be overboosting as the duty cycle would be set to ten, and the gain set to 0.. meaning the ebc will hardly be working at all. So effectively your setup should be running at almost wastegate pressure on any profile that hasn't been touched.

As to how the unit works, you can't specify a psi with the unit. You can only set the duty cycle which will directly affect the boost level. The higher the duty cycle, the higher the boost.

This manual should help heaps if you haven't seen it yet.

Ill break it down in short

When I go to "change" the duty cycle by holding button 1. While I'm in profile 3 and 4. It still shows 10.

But profile 1 and 2. Over boost while also set on 10

Other issue is when I hold button 2. To adjust gain. It flashes 00.0. And neither button does anything

Also I think it's just an ibc. Not ms. As it doesn't go up to 50 psi. And only has 4 profiles not 6

This is the one I believe I have

http://www.gizzmoelectronics.com/pdf/IBC%20Instruction%20Ver1.06.pdf

Ok so after not really getting any clear information of my friends I tried playing with profile 1 and 2 as 3 and 4. Seem to work fine. Running just under 10 psi

I tried doing the opposite. And working back from the highest setting. Still over boosts

The gain cannot be adjusted. I notice when I set my desired duty cycle it makes a funny noise in the engine bay. If I set it on 10 or close to like 11 it's a very short noise. But it is continuous if its 20 of over

Could it be possible that the controllers just shagged?

Ok so I got it working and the gain seems to work

Went up in 2 point intervals. From 10 duty cycle then using 20. Doesn't really make much difference. Maybe 2 psi. It's not showing on the boost guage much difference. I might bump it up again

What should I be setting the gain to

Yeah I usually use manual ones. That way no problems. (Generally)

But seeing as the car already had this already. That's why I've played with it but yeah sused it all out now.

Cheers guys

    • This is awesome.     
    • Thanks for the quick replies guys its appreciated. A small extension was welded onto the standard 6boost external gate pipe which you can see where the pipe goes from black to stainless just below and to the right of the rear housing in the first picture. Overall I would say the flow is pretty good other than 6boosts choice to come straight off the collector at a decent angle.. Not sure why I went with two valves, I originally replaced the stock twin bovs with the GFB when I had the twins on. When I purchased the EFR it came with the Turbosmart Kompact BOV so I figured that would be a better option than the stock EFR Bov. I don't believe the Turbosmart BOV is adjustable? When I get the spike and then sudden dip in boost pressure, the turbo speed does drop as well. Stock head size wise however I believe it has Neo Turbo springs and a Neo Turbo intake camshaft and an aftermarket exhaust camshaft in the vicinity of 260 degrees. We didn't try a different MAC valve, we tried two different ways of plumbing it and we also tried removing the mac valve entirely and just having the boost source from the turbo directly connected to the wastegate and it still spiked / dropped and exhibited the same behaviour. Standard R33 GTR 5 speed tansmission. I'm running a Haltech Elite 2500 and can provide some logs if you. I understand what you're saying in that it looks like an auto plot however no, it's still a manual and it just has a lot of torque down low, for all intents and purposes it's a very impressive street car. I've attached a photo of the quickbitz dyno plot which was when the only difference is I was running -5 twin turbos with a mac valve. As you can see theres a decent dip in AFRs between 125kmh and 135kmh. Our problem now is not that the AFRs are dropping, just the boost pressure is dropping, however it is evident in the same RPM range of the map, coincidentally or not.
    • What transmission are you running?  It's a bit tricky with the scaling, but at face value the power "curve" looks more like a "line" which is a bit odd... basically a lot more like a dyno plot I'd expect with a highish (compared to a factory auto) stall torque converter type setup. If this is running an auto then this kind of boost control challenge is definitely a thing, the rpm scale on the dyno doesn't reflect what the engine is actually doing (unless the dyno has access to the engine's ACTUAL speed electronically) and what you'll get is a big rpm flare up as the engine torque launches past the converter pump's ability to resist torque at that rpm, then as the converter starts picking up rpm it will kinda even out again and the engine rpm will pick up more steadily. The trick with this "flare up" is if it's kinda near the boost threshold for the turbo then the engine's airflow requirements to maintain the previous boost level will outrun the turbo's ability to supply that boost - so you end up with a natural flattening off, if not dip when that happens.   If you are running closed loop, or even tune the "feed forward" wastegate duty cycle to deal with that rpm spike then when the engine starts settling to a more typical climb you'll actually have a situation where the gate is "too closed" and boost will run away for a bit, then have to pull down again.      It's not trivial to get this perfect as most boost control systems are generally expecting more predictable engine rpm rates of change, but if you *know* that's whats going on then you can at least "accept your fate" and realise getting that area perfect is kinda chasing your tail a bit, and assume that if the rest is working sensibly and the spike/dip isn't completely uncontrolled then you should be good. Sorry if I've gone off on a tangent, but the dyno plot and boost control behaviour look a LOT like what I've seen tuning autos in the past. What ECU are you running? Could possibly be convinced into looking at logs if I get too bored this weekend haha.
    • A few things that seem a bit off here. - why is there 2 BOV’s?  - the turbo smart BOV on the compressor housing, is it turned up ALL the way? I have seen this become an issue on old man Pete’s car. It would push open and recirc, turbo speed would rise and the boost pressure would do weird things. - stock head? Does that include springs? - tried a different MAC valve? Is it plumbed correctly?
    • Photo of manifold showing gate location? I mean, it's 6Boost, so we probably shouldn't be worrying, but always wroth knowing what the layout is. Plumbed back to atmosphere? Or into the dump?
