Fitted MBC

[Ep'd]

I have ordered a hks fcd to prevent fuel cut and also have ordered a high quality manual boost controller ball bearing type to prevent boost creep.

I have a ct9 turbo, stainless manifold and front mount.

1. Would I need a fuel pressure regulator if I am only running 0.8- 0.9 bar boost. I am to set it once and leave it to 0.8-0.9 bar no more no less.

******2. If I run at 0.8 do I even need the fcd or fpr?? I'm happy with using the manual boost controller for just 0.8 bar 12 psi boost.....

Thanks again appreciated its all a learning curve

U will need a fpr with a fcd, for yhe mbc u just fit it between the actuator and turbo.

[Ep'd]

Fitting sounds simple.

I only want to up my boost from 0.6 to 0.8 bar boost set the mbc once and leave it to 0.8 for a little bit more kick.

It sounds like a plan as I will be happy with 0.8 bar...

If I do this I do not need a fpr or fcd do I??

Mbc wont prevent boost creep. You need to port the wastgate to do that.

[1990timeismoney]

You could by a plug and play ecu

[AdamB]

If you only plan on running 0.8 bar, ditch the FCD and FPR and just run it as stock. Only when you go over 0.8 bar will you need the FCD and FPR to keep things safe.

[Glanza-Ben]

Manual boost controllers spike so if you set it at 0.8 bar it may spike over and hit fuel cut with out a fcd so get it on and fpr to help out fuelling

Not only do they spike, they are very hard to control and need adjustment virtually daily.

[Ep'd]

Ok! I cannot seem to win as mbc's apparently do not work for under 1 bar boost! I only want to up it to 0.8 bar

What happens if I go for a hks adjustable actuator and set it to 0.8 bar and leave it to that without a fpr and fcd? Will that solve my headache?

You'll need a FPR with the FCD, or do it properley and get a piggyback ECU for 1 bar. Cheaper than a stand alone which isn't required for 0.8/1 bar anyway. Also replace the standard actuator for an adjustable one like HKS, pretty cheap second hand and that'll control the boost quite well.

You'll probably hit fuel cut i think

[StuDoc 72]

For 0.8 bar.

Use a hks adjustable actuator.

Port the wastegate on your turbo.

Thats all.

Then add an EBC at a later date.

MBC - not worth a fuck.

FCD - accident waiting to happen.

Best thing you could do would be to add a P&P to the list aswell. Can run what boost you want on ct9 and allows you to continue modding.

Do it right do it 1ce.

[AndyMB]

I run about 0.8 bar. My car was set to that when I bought it.

I have:

HKS actuator

CT9 - Wastegate may be ported

RRFPR

HKS FCD

Standard ECU

Never hits fuel cut, runs really smoothly. I don't think the FCD is really doing anything to be honest.

Buy an emanage blue and get it mapped be safe with your engine you will just end up killing it iev seen it so many times emanage blues are cheap now a days ied rather spend a bit more on getting it mapped right than buying a new engine when it pops just my opinion tho

[Ep'd]

Ok I'm going to get a hks adjustable actuator but won't be able to afford to port my waste gate and run only 0.8 bar boost.

I think that should be ok I should not hit fuel cut or boost spike this way long as I keep it to 0.8 and no more, agree?

[StuDoc 72]

What other mods do you have?

If you have an FMIC and/or front mount air filter chances are you will creep and hit boost cut.

Port your wastegate yourself its easy.

This. I ran mine for a few months at 0.8, stock ECU with above mods. Ran perfect. No need for ECU and all the rest of that overkill unless you wanna run higher boost

[DavidAshton]

Who has told you MBC's don't work under 1bar? Total crap.

They also don't spike and the don't need adjusting daily. I have been running one on my TD04 setup for years and previously on my first Glanza with a high flow CT9 setup. I get more stable boost with my MBC than I did with an electronic boost controller!

Just fit the MBC, adjust it until your boosting 0.8 bar and off you go. If you start fuel cutting look at that as a separate issue.

That's its job though, tricks the ECU into thinking everything is OK so you won't hit fuel cut, just starve the engine of fuel if the fueling isn't set right

[Ep'd]

I just thought at 0.8 bar no additional mods were necessary if you have a adjustable actuator at 0.8 bar

I'm confused!

Last question! Ok MBC on the way!

Just one thing I disconnect the hi low boost solenoid that's already there and do the bypass is that correct? Then plumb the mbc in.

Or can I still leave my hi low boost solenoid with hi low button still functioning with a mbc?

Fitted my MBC what a piece of kit transformed the whole car

Set to 0.8 bar but sometimes rarely spiked to 0.9 occasionally but does not hit boost cut at all.

Running up to 0.9 on the occasional spike is that ok?

[Ep'd]

?

[Amjad]

I don't think the factory ECU can fuel above 0.8. So despite it not hitting fuel cut, it may be running slightly lean if you know what I mean?

Would be sensible to lower it a bit, as it will defo creep when it gets colder too

[RobSR]

If your below fuel cut and not hitting it, itll be fine.

[Ep'd]

Ok cheers guys. It goes from 0.8 to 0.85 now no fuel cut all pukka ;)
