Ebc. Apexi or greedy

[T3rra]

Thinking about going stage 2 soon on my turbo. Getting a new hg then going dpw and ebc.

However which one? Currently got the choice off ethir with only £90 difference.

Apexi acvr been the more expensive. Why don't done one make one as single/ twin din which also works as a headunit? Would keep things looking clean and discrete.

Do all the extras on the apexi really get used?

Thanks

Greddy for me. The A'PEXi has more features but theyre so difficult to set up. Does anyone ever fully utilise an EBC?

 

[bighead]

probably not, but still.....apexi for me

I had the Greddy and liked it. Relatively straightforward to setup and held boost dead flat to the redline.

The controller is nice and small so easily sticks to the top underside of the cubby under the radio or I had mine in the glovebox.

Probably overkill on a level 2 set-up. You will set the boost once and forget about it. A MBC will do this effectively, simply and cheaper plus you can still adjust it if you want. I have seen dash or console mounted MBC's although mine lives in the engine bay.

If you plan more exotic upgrades though then knock yourself out and get whatever EBC you like. I have heard both work well but the apexi is overkill and harder to wire up and then has lots of functionality you will never need although I think barks did a sticky on how to install one!

Thanks, cars used daily all year round so there may be a time where I need 2 turn down the boost. Is it Simpler turning down the boost, would that change the expected fuel sirpuly ?

I do think it be set up and left. However Iv got an chance 2 get a new one 4 £290 and they hold there value resale wise

Only caveat to this is that the MBC will not hold boost as strongly, consistently or for as long especially at the higher end of things as an EBC. Certainly noticed the difference when I swapped.

On the side of the MBC, a good one will hold boost just fine and they are simple cheap and reliable! Also EBC's can be irritating due to the clicking noise of the solenoid. But they can do cool things like throttle/rpm based boost control. What boost level are you planning on running? Here's my boost log with a turbosmart boost T. There is some fluctuation but its no great and the MAP measurement is made using an in plenum MAP sensor which is very accurate and responsive, you wouldn't notice it on a boost gauge.

Boost wise, 18/20 what's ever safe and can be got with k26/8.

In the future there maybe some bigger upgrades but it will most likey stay at stage 2.

Would be nice 2 adjuset boost from inside the car and on the move, based on mpg and weather / traction issues.
Ideally be nice 2 have something that easyly read when mounted discreetly.

This is my 1st turbo car so its all a bit new. Boost levels per rpm and stuff would make it easyer 2 data log any newer mods and 2 test out Jmg newish chip set

 

[barks944]

The standard DME is not well suited to running variable boost pressure. Its setup for a specific boost and that's it. It's pretty old school in the way it works. I have a lot of experience modifying and tuning these engines and the first thing I would invest in would be a wideband Air Fuel Ratio gauge.

Read this: http://en.wikipedia.org/wiki/Air%E2%80%93fuel_ratio

and then read this: http://en.wikipedia.org/wiki/Engine_knocking

Learn about these things, be afraid of lean running and detonation which are all things you will risk if you are playing with boost pressure! Monitoring your air fuel ratio is a great way to make sure these engines are in good health. Before you start tuning and messing with it get to know it. AFR gauge will let you know about problems with fueling and boost leaks. It will save you time money and effort in the long run. They are about £150 quid and you need to get a boss welded into your exhaust at an exhaust place. A lot of engines get problems with fuel rail pressure regulators, pumps, boost leaks and other things that can cause you big problems.

My current car, and previous car worked perfectly with MBC.
As Stuart & Tom have said, they are simple and reliable (they are actually small industrial pneumatic Pressure regulators).

The bling modules only regulate the pressure rate of rise which an MBC cannot do, but as they limit the ROR they reduce the torque.

My right foot has a ROR sensor which does the same job most times [8|]

Save yourself the cost, and hassle of setting the unit up.

Thanks, barks that's sort off thing I was wondering if its best left set rate. Based on the fuel and air mix rather them runing 2 set rpm which MIT not macth the fuelling and air.

Elliot is that another fan off mbc?

These mbc? The ones 4 944 seem expensive compered to manyothers are these due 2 Porsche tax?

Ebc will give me an easy 2 read psi/bar reading which will stop me over setting or under setting it, but it will be set up a Jmg so r prob just leave be after.

Wideband and mbc is better then ebc? Cost.

 

[ChasR]

As another choice, what about the Gizzmo range of controllers? They seem to be popular in the Japanese scene and apparently are great value .

 

[944Turbo]

I had good results with my greddy b spec, better than an mbc,

[T3rra]

Think I'm going 2 go ebc, as I don't fancy setting boost manual every time 2 out side temp.

Then I'm back 2 the same question is the apexi worth the £90
More? There a £500 rrp. So £290 new is a steal? Iv seen them sell used 4 close 2 that

Can people post pics off how they mounted there's?

Thanks
Terry

 

[barks944]

Whats the relationship to outside temperature that concerns you terry?

 

[T3rra]

That with a mbc u will need 2 adjust the psi 2 macth ? And ebc dose this 4 you?

Iv i been miss lead? Have a bit off a read on some older treads on rennlist and tipec.

Ebc will prevent boost spikes and over boost better?

Terry, give Mark a bell at JMG. He very neatly installed my APEXI-Avcr (cut very, very neatly into a radio blanking plate-Scramble boost button alongside it [8D]). It looks the mutz nutz and, is an awesome piece of kit![8D][8D]. Makes the car mental to drive! No, you don't need all the features that it posesses but, it sure is nice to have them readily available in case you need them in the future (you may want to turn your car into a balls out trackday car)! Mark reckons they are simple to set up and, i wouldn't be without mine now []. For the record, to buy new in this country, they are around £600. I bought mine off of flea bay for £250. Excellent condition and works perfectly. A no brainer really!![]

 

[T3rra]

Just doing the deal now, £290 4 a new unit. Lets hope it real

What you running ? Bar/psi and mod wise

How do u find your self using the unit? And scrabble button? Jon said I may need it 2 shake off gt3
