Ordered this am from Coordsport HKS Super Drager |PLS| Ralliart Panel Filter |PLS| ARP Bolts. Asked Phil about the MOTEC ECU - he put me off by saying that for everyday use it would probably be unsuitable. In that cold start would be a pain etc.

However, the Ralliat Sports ECU for the SEVEN does not require a boost upgrade as its all done by the new ECU. This then is the way to go as far as I'm concerned. Will decide after the ARP bolts have been fitted.

Has anyone else with a SEVEN swopped ECU's? if so can you offer any thoughts?

hi jerry this is interesting?
i have just spoken to ralliart yesterday, and the advise i was given is that the sports ECU for the 7 is pointless. basically i was told that the standard 7 ecu will cope with up to 1.4 bar of boost in standard form. and if i wanted to go higher into the 1.5-1.6 region then the ralliart ECU will be beneficial, however to run that much boost and keep my warranty they will need to do the interenals themselves as well.

so how much boost did they say you could run with the sport ecu as opposed to the standard?

i should be finding out the fuel cut/ boost limit of the 7 next week when my boost controller arrives

Hi Sam

Which fuel cut/boost controller did you go for?

 

[Guest]

Sam,

Interesting bit of info there-- 1.4 bar ok with the standard ECU? Is this confirmed anywhere else? Not saying it's wrong, but just want to be sure.

Would it be safe to up the 7's boost to 1.2 max with stock internals, and only a filter mod (i.e., no downpipe and exhaust,) or would this be pointless if not dangerous? I assume 7's standard boost is at 1 bar?

Thanks

Don't know the answer's to the above questions - I've asked Phil to browse the board - hopefully he will e-mail me with the answer!

hi there
my evo 7 gsr boost to 18psi that is about 1.2bar as standard. it is ralliart supplied and is decatted. so 1.4 bar sounds very reasonable to me.

EVO7
i will mail you later regarding my boost controller. as it is still very experimental work but should be very interesting.

 

[Guest]

Reading over the above postings and it reads that Ralliart and Coordsport are giving out conflicting information.

 

[Guest]

Why should cold start be a problem with the Motec? You can map that without any problems. If that was so why do the WRC run in Sweden? All the WRC teams bar Subaru use Motec. I even have a DVD of the the last season Mt. Carlo pre-testing in snow and the cars start as easy as our standard cars.
The problem with Motec is its unability to control the iddle stepper motor on the EVO. You have to shut down several cylinders on iddling or get a controller from Prospeed.

Hesperus,
The EVO 7 standard boost is indeed around 1.2-1.3 bar. I have known one run at 1.5bar with a standard ECU and no fuel cuts, so 1.4 bar would be ok providing the ARP bolts are fitted as a precaution.

Not going to criticise Phil - he answered my questions honestly. He knows that I want a car with more bhp - but not at the expense of day-to-day running, so he said get the Sports ECU! Yes, I would have liked the MOTEC, but they have to be setup correctly for them to be of any use. However, if anyone get recommend such a specialised agent then I'll re-examine the MOTEC, as I fancied antilag and launch control! I could have got one for around £1550 from the United Arab Emirates - however the agent mentioned he wasn't sure if they were suitable for the SEVEN!

So, you now probably understand my dilemna - I imagine MAD or Steve Hill Motorsports may know the answer!

PS. Just fitted the Drager - this has an internal baffle that is removed similar to the Blitz for the SEVEN!

hi jerry
the motec is a stand alone ECU that will work with any car really.
my best friend has a e6 gsr running motec and once it was set up correctly he never had any problems with idle or cold start. the M48PRO which he has uses the standar ECU for idling any way.

that is the point, the internals will be ok for 1.5 bar so there is no point running it higher and there for the sports ECU is not needed for the 7. still to be proven though.


what do you think of the dragger? i am thinking of getting it myself. is it from the cat back? and have you removed the cat yet.

thanks

My 7 Extreme uses the Sports ECU. It boosts to 1.5 bar ( I believe) but I have heard stories that it does spike higher. That is why I want to fit a boost gauge. This will not be for about 10 days though, but I will try to remember to report back. It should be noted that I have upgraded internals.

I have been looking into the ECU situation over time and have come to the conclusion that until you plan to really go for big power, going down the Motec/ GEMS route is overkill. If you think that you might do some head work and fit different cams in the future, then you might as well get one of those ECU's straight away. However, if you don't intend to go much past the Exhaust/induction stage, then it probably is not worth the money and the hasle of mapping it.

please keep us posted. i have been told that the extreme runs 1.6bar to compensate for the extra weight over the 6.

[Guest]

Sam elassar,

Which version of the extreme are you refering to Extreme or Extreme S.
The Extreme S comes with the gems ECu and some other engine mods so
it might run at higher boost

 

[Guest]

just the standard extreme. the extreme s runs a lot higher than this 1.9bar i think

 

[Guest]

That sounds about right, although I think there are situations where the S might peak at 2.0 bar (no certain on this one).

 

[Guest]

Sam

Sounds as though the MOTEC is still the way to go then. Very pleased with the Drager - not advertising but rather than write it all again have a look at http://www.jerryflint.net/EVO VII Diary.htm Surprised that it has a removable baffle.

Simon

What engine mods has the Extreme/Extreme S. Couldn't find any info on the Extreme on Ralliarts site!

 

[Guest]

well, i am going to the UAE in the 2nd of march if that is any help? talking about vat here ?

Both cars use forged pistons and con rods. Full spec is on the forum somewhere! Either myself or Blade did a cut and paste from somewhere???

Just read your diary. You are clearly begining to catch the 7 disease - more you drive it the more you realise how much of a great everyday car it really is. Soooo civilised and just great to drive. Not better than other Evos, just a slightly different driving experience.

BTW, love the frosted windows to match the paintwork. Stick on or etched

Hi Jerry/ Sam
I posted something on this subject a while ago but even I cannot find it on the site! Basically a 7 will indeed push 1.5 (or even a tad higher than 1.6) with the grommit removed. I know this as my buddy has one and has run it relaibly like this (with the ARP bolts) since the Spring of 2001. He has a HKS boost guage fitted which I would think is accurate enough. With the recent cold spell he HAS experienced fuel cuts however and he is considering the following options:

(i) Go for the Ralliart Sports ECU (which does indeed cure the fuel cut problem but does not give you any more than 1.5 / tad over 1.6 boost
(ii) Go for the GEMS unit (comes with a 2 bar MAP and very nice!)

The Programmable route take a LOT more setting up and are not simple plug and play (like the RA Sports ECU is) but I can honestly say that they are worth it! The Cold Start is the hardest to get right as you really only have one go at it (each day after leaving the car overnight for example) before the engine goes onto the Warm Up Table. Both GEMS and MOTEC have in built boost controllers too which when you take that into account brings the price to a more acceptable level.
Good Luck with your choices.
