Al, can you please elaborate on this. If I don't plan on running anything other than 91 pump, what is the benefit of the BC? The only mods will be a panel filter and a reflash.

 

i personally lik a mbc

keep in mind - no matter how great the ecu front end softwear is - you are still dealing with a very primative set of hoses and pills with the factory set up - its hardly a high performance set up

A MBC gets you the best possible boost function and control for about $85

With a turbo car - I like having end user adjustment of the boost

 

Can you exlain the difference between your software tune and Ecutec?

I have a dynoflash with MBC and dont like the fact that I get a very high boost spike. And weather changes that effect how my car runs. Can I retune with factory boost solenoid and hold 21PSI to redline?

 

I notice that more EVO owners prefer MBC rather than Electronic boost controllers. I know that MBC are less expensive and pretty precise, but wouldn't having a EBC have its advantages.

 

+1 Why is a MBC better than a EBC is a $$$ thing? Also, why do so many people run a MBC when the factory parts can hold 21-22lbs? That would be adiquate for me..

 

Yes I believe that the MR bypass holds 21-22. So if this is true and you only run 91 because that'a what we have in Cal an MBC really is only useful to detune your car for Wife's Son's etc..Just trying to figuire out why I should buy one as well.

 

You do not really NEED one. The stock setup, if configured properly will work very well for the street.
Some like the Manual for ease of use when at the track, or for valet purposes etc.
But for the most part it will hold a good boost level to redline. Above a certain level other factors play a role in maintaning boost pressure from the turbo.

 

What makes an ECUTEK flash superior to that of the Traditional flash?

 

more flexability... more readily available maps

 

The MBC is a nice and inexpensive piece of hard that allows for user adjustability. I personally prefer an EBC as I prefer to have full control of low boost and high boost while driving.

That said, the stock solenoid, when properly setup, allows for better control of boost stability and response. With the Ecutek software, the boost is mappable both with a master boost setting as well as by RPM and other parameters. This allows the tuner to fine tune boost parameters and often can assist in reducing or eliminating unwanted boost conditions such as boost surging or boost spikes.

The disadvantages of the stock solenoid is that it is much smaller than that of aftermarket EBCs, thus requiring higher duty cycles to control a given amount of boost. For applications over 400whp (on the MD dyno) we recommend the use of EBCs such as the AVC-R for greater boost control.

How does the perrin ECBS compare? Its what I've got, (I usually don't make uninformed purchases) TopSpeed sold it to me when I had my EcuTek tune, and since I didn't plan on changing the boost level it seemed like a good choice.

 

So you have the EBCS on your Evo with an EcuTek tune from TopSpeed? I've been curious about this combination ... how does your boost look in terms of initial spike and holding to redline? Do you have any dyno plots of the boost logged that you can post?

 

I just installed my boost gauge this weekend. It spikes to 24psi and holds 21psi till redline. I've got a paper print out of the dyno, but it doesn't show the boost pressure, just hp, tq and air/fuel. And I don't have a scanner so I can't post it. The only thing about the EBCS is that it makes a ticking noise, which is normal but can be annoying.

 

Holding 21psi to redline is pretty sweet. That should pretty much put the nail in the coffin of the foolish argument that you need an MBC to raise boost above stock.

What is your complete mod list if you don't mind?

And there are 3 different ways to hook up the EBCS I think: bleed, fast response, and intercept (or something like that) ... I don't suppose you know how they hooked it up? I'm really curious if TopSpeed is recommending this on all their EcuTek tunes or what?

Good info, thanks ...

 

I'm not sure how they hooked it up. I wasn't even aware that there are multiple ways to hook it up. haha. I think that they recommend the EBCS to people who aren't going to mess around with the boost. I have no intentions of running 100 octane and jacking the boost up.

For mods I've got a buschur turbo back, a K&N drop in, perrin EBCS, the tune, and 42 draft designs gauge panel (boost, oil, volt). The car made 323awhp and 300awtq on Topspeeds dynojet.

BTW sorry for the delayed response.
