I will break it down for you step by step

STEP 1 - Base Line stock - 100% stock no parts

STEP 2 - Add Buschur BR350 parts - stock cat - NO TUNE




STEP 3 - Tune the car - combination of BPU parts + MIVEC and tuning changes = power gains

 

Thats what I thought.
Its all I wanted to hear Al, let the games begin..
Forget answering the question.

 

I sense a lil tension there lollll We'll see what happens

 

Ok guys. If things get uncivil, all I ask is that any discussions regarding the Al/Buschur dyno testing technique should go on another thread. This one has already taken a big enough tangent as it is

Can anyone say "Hijacked Thread"?

Maybe Shiv could clear up the other gentleman's question about the Boost...

 

Civility isn't a problem. Just asked Al, a question. I must have stepped on someones toes...
Buschur racing is not involved nor questioned in the least.

 

What is the matter Shiv - we are all taking about "not so offiicial Evo IX tuning" here ? I think everything is most civil thus far?

 

My worthless 2 cents, those of you who watch Best Motoring already know this ... most of the increased power in the low to mid range comes from the new Turbo due to its enhanced compressor wheel which has an increased diffuser size, revised design and magnesium for the wheel. Apparantly this increases the response of the turbo. This was straight out of the Mitsu engineers mouth ... From what was said MIVEC increased fuel efficiency and emissions but like VTEC I am sure it helps flow in the upper RPMs. When they tested the EVO9 vs the EVO8, stock the EVO9 shown leaped out in front of the EVO8 in low rpms but once they hit the upper rpms they were dead even (i.e. 9 wasn't pulling away) which agrees with the baseline dynos that David Buscher did. The new ECU is probably also a step up and allows a more aggressive tune because it allows the tuners to play with MIVEC settings.

It is my opinion that an EVO8 with a EVO9 turbo, a tuned aftermarket EMS (possibly even reflash of the stock ECU) and cams that have a higher lift will produce the same power as an EVO9, if not more ...
I have a nagging suspicion its mostly the new turbo...

 

I don't know Nick - I dont see any problem with us asking questions and engaging in civil dialouge regarding Evo IX tuning.

After all - the 3 of us are all registered paying vendors which support this forum and we are all authorized Ecutek dealers.

 

You are right Al, no problem being civil, but when you make a comment like that (BTW that you conveniently erased, But I quoted) brings hostility to a thread that so many vendors are posting in.
Especially Vendors that Obviously have had issues in the past. Along with the fact that lately for some odd reason we have been thrown in the mix as well.
Patronizing the rest of the "EcuTek" dealers is not your strong suit.

 

Good points. The turbo no doubt is reponsible for most if not all of the power gains.

My testing showed little or no gains up top with the MIVEC.

The MIVEC is going to ZERO up top and is working significantly in the lower rpms area.

I will post up some more details on the MIVEC cam settings which will amplify this subject.

 

The way the vehicle is mapped from the factory the Mivec is the reason for the low end spool up characteristics.
The larger compressor and its efficiency is what shows in the midrange and up top.

This is by far the best thread and most informative thread I've read to date on evom. Keep it coming guys.

 

This is an awesome thread, Shiv. But just be glad you aren't trying to tune Saab's Trionic 7 engine management system. It has over 1,000 individual maps. It also has very unusual "functions" which apply to a airmass/WGDC map and some for the electronic throttle. Very unusual. So far not one single aftermarket tuner has altered the maps in the way that Saab intended except Hirsch. But the guy AT Hirsch is the one who helped develop the ECU in the first place and he wrote the maps for Trionic 8.

And, yeah, this is a really damm good thread. Props to you, Shiv, for starting it!
