FMIC set up help

[Midnightclub]

Don't adjust the boost until you have the cooler on!

[Jonny81191]

yeah, but don't turn it up without a remap to match!

[ANTB1986]

Yeah intercooler has been on for a week now and just can't see how someone can get their hand in such tight space.

[Poodle]

You need the intercooler if youre going to turn the boost up. You dont have to go stage 2 once youve got the cooler on, bu it seems daft not to, youll have done the hard bit then anyway lol.

[Midnightclub]

When my HDi was stage one with the FMIC, had the boost at around 17psi and it went well even with that!

[ANTB1986]

Did you take the engine out to upper the boost?

[Midnightclub]

Urmm nope, just used a long 10mm spanner and adjusted the actuator took all of about half an hour from start to finish including putting in on and off the axle stands a few times

[ANTB1986]

Oh ok. Will have to get it up and get my hand in.

[Midnightclub]

If you lie on your back looking upwards then it's a lot easier, once you see where the actuator is it's easy to see how you adjust it

[ANTB1986]

I can sort of see it but the air filter pipe goes right over it so it's hard to way.

[Midnightclub]

It shouldn't do :S

Iirc, there is a bracket you can take off, and unplug the oil feed pipe to the turbo. Taking them off makes access for adjustment easier. You can probably leave the bracket off for a quick smooth road test, just don't let the car shake around too much... obviously DO refit the oil feed pipe before a quick test drive to check the adjustment, and DON'T forget to refit the bracket once things are ok

You can adjust boost once FMIC is on, but the mapping also boosts fuelling, the higher the mapping the more boost you'll make. A standard HDi makes about 15psi on 90bhp mapping, but with 120bhp mapping and an FMIC it'll make about 16-17psi, and then with 150bhp mapping probably 17-18psi, so the adjustment is only tweaking it up a few PSI really.


MBC is a pain to fit. I don't really see the point in them as they just lag the turbo wastegate response and make them boost spike more, and the last thing you really need on these cars is ALL that torque coming in suddenly as it just makes the lower gears even more useless. Once in the higher gears you have 'acceleration' lag (ie, revs can't rise that quick vs boost), so the presence of the MBC's lag isn't really noticed.

Handy to tweak up, but how often are you really gonna tweak boost once you've got it right?

Also lots of failure points. Costly. Also really bad if you snap the boost take-off or inlet on the compressor housing or wastegate actuator body, as it's a turbo/engine moved/out job to get the turbo out and fix it all properly (seen it done opps!)

So just turn it up to 17-18 psi then bang a remap on it? Can I still use a standard clutch (NEW) as I won't be abusing it that much as iv always got my 10month old son in the car? How much do you cost for a stage 2 whippy?

[Poodle]

A new standard item will probably be ok if you dont abuse it.

[Midnightclub]

My brand new standard item has been fine so far.. held 270lb ft on the dyno no problem

[ANTB1986]

Happy days then. Defo getting under the car tonight to have alook at finding that arm on the turbo keep putting it when I finish work but got an early finish so will update when iv had alook. Will be posting some pics up next weekend as my car is going White next week

[ezb]

I thought you were trying to sell this car??

See it about all the time, I'm the idiot in Crewe with the red/yellow d-turbo lol

[ANTB1986]

I was yeah but can't let her go lol. Not sure if I seen your car. How do you know it's me?

Have you got bright bright bright yellow wheels lol ?

[Poodle]

Yes he does lol.
