When I saw Wiltshire, I was going to suggest Norris, certainly he's well respected generally in Evo circles.

If it's any consolation, I've given up on Mitsubishi dealers full stop, I have a friend who's extremely knowledgeable about Evos.......the downside being that it means either me travelling to Newcastle from Southampton, or him flying down and staying at mine whenever the car needs work. After all the nonsense I've had over the years, it's a small, albeit inconvenient price to pay, and invariably means I get what I want.

That's Karl Norris in Derby not Simon Norris

Oops, my bad, don't know about your guy, hope it works out.

[stevieturbo]

You wont go wrong with Karl.

But dont feel so bad about the previous fk ups. There are hundreds of "specialists" out there just as bad !

[jontysafe]

Have spoken to Karl who point blank refuses to map the car with the Apexi boost controller. He`s recommending ecu controlled air injectors with a pectel board and 12 position boost control. That`s going to cost 600-700 plus live mapping and no doubt a few other bits and pieces which will no doubt add up to about probably 1.5K. Question is do I just bite the bullet and go aftermarket standalone? I got a quote for a standalone (canems) installed with new engine loom (no cut and splice), dizzyless wasted spark and mapped for 2.1K. It involves ballast resistors so not keen and it`s not widely used on YB motors. Not that they are complicated!

Research any aftermarket ecu before buying. I would agree that ecu boost control can be better, but the AVCR when set up correctly is a very capable controller.
But it is a complete and utter PITA to set up, and must say I hate them too for that reason.

And boost control on all ecu's are not the same, as are most options. Just because they say they can control boost, on it's own means very little.

Some might just allow 2 settings, some 3, 4, or even up to 12. But on top of that boost vs rpm, gear or speed. Or any combination of those.

Then things like knock control, traction control, launch control etc.

You may not use them right away, but nice to have them for the future. So dont just consider the ecu as for the engine alone, but for the entire vehicle.

I wouldnt be too worried about using ballast resistors, it's fairly common with some vehicles. And at a alter date you might upgrade to better injectors anyway which would be high impedance so no resistors needed anymore.

But the cheapest and easiest will be sticking with the Cossie ecu and going down the route Karl suggests.

if you want a very capable ecu that will do all of the above, along with excellent safety strategies for oil pressure, fuel pressure etc Speak to Paul at Zen Performance or Ryan at 2bartuning about a Syvecs S6

Or Charlie/Vixpy1/Surrey Rolling Road who pops up on the forums from time to time can point you in the right Syvecs direction..

Or..talk to EvoDelta, deltaparts.co.uk. He has recently sorted some plug in options with a standalone from Specialist Components for the Lancias.
They use pretty much the same ecu as the Cossie, so might be an option.

Interesting thread this.

I have no experience of YB's or kit cars but I have just boosted my MX5 and I would suggest that if going standalone go with what your chosen tuner is most comfortable with as they will be the ones working on getting it running right.

I tried runnnig my boosted 5 on a piggy back solution and rising rate fuel pressure reg. It worked but it was not great. The guy who I use is a Megasquirt man through and through. I bit the bullet and bought an MS ECU and he's got the car running beautifully. All I need to finish off the current install is some bigger injectors as I'm maxed out at 6000rpm on the current ones.

Good luck and keep at it, these things always cost more than you ever imagine but the satisfaction when completed and working is huge compared to buying an already good car.

syvecs S6 does look very impressive.

I wonder whether it will run my siemens injectors?

[jontysafe]

Stevie can I pick your brains a little ref a cold air intake? At the mo I have air filter directly on turbo housing, not great for getting colder intake temps. I know air box / filter design is crucial on NA cars but is it so crucial on boosted cars? I am thinking of just getting a. 102mm 90 degree pipe and cutting a hole in the side of the bonnet so air filter is drawing from outside. Will this cause me problems because of high air pressure at higher speeds or will the turbo be sucking hard enough to counter any issues?

It cannot directly run low impedance injectors. So you would need a resistor pack until such time you upgraded to high impedance units.

Cold air is always good.

Air always moves from high pressure to low, same as anything. So if you are drawing from a high pressure area, then it could only be deemed a good thing.

[jontysafe]

Actually have I got that right? Isn`t the fast air moving over a car body low pressure? In other words an aircraft wing has low pressure on the underside as the air is faster over it creating lift?

Probably not valid in my case and I should just stick the air filter outside of bonnet, it`s just expensive if it doesn`t work after I`ve cut a gert home in it!!

No, you've got it the wrong way round, the upper surface of a wing is at a lower pressure than the lower surface.

ok that makes sense!

Any tips anyone on cutting fibreglass?

Fine tooth saw, drill, sandpaper etc. A bit like working thin wood, but a bit more brittle.

Like Stevie says, I've been working with SpecComp on Ecus, so if you want one let me know. They are quite high spec for the price, factory back up and in the Uk too. Creator Simon is the Ex Lotus ECU guy and very helpful. In these days of remote access to laptops etc setting up problems are easily solved.

[jontysafe]

Hello there Evo, thanks for the message. I might try and find some fibreglass to practice on!

Ecu`s look interesting! They obviously run low impedence injectors? Who can map them?

Where in Wilts are you? I am in Swindon and will be doing some fiberglass trimming on my Westfield in the next couple if you wanted to see how I do it. I roughly cut with a fine toothed saw then finish with a dremmel with the rotary sanding tool. It cuts really neatly but very quickly so don't use much pressure.

[jontysafe]

Hi there, I'm pretty close to Swindon. Can I come along? Only if it's not raining though!

Yes they will. If someone calls themselves a mapper they should be able to map with any ECU, if they can't I'd steer clear! The software to map it is downloadable for free, the comms lead and dongle to convert it to a USB port would be included as part of a package as would a starter map. It should just plug in and start up and you map from there.

Should and being able and willing arent the same thing though.

For many reasons lots will stick with what they know, as they know they can give good results.

It's a bit like the Megasquirt scenario. Lots of people use it, some with good results. But lots of tuners wont touch it.

Hell..even some dealers for ecu's they sell daily, haven't even a fking clue how to tune what they sell !!! AET Motorsport and Turbonutters Haltech balls up being a prime example.

So it is something to consider. Yes most competent and able tuners should be able to be flexible and versatile with tuning different platforms. Some just dont want to be bothered though as they dont need to.

Then personally I wouldn't entertain them.
I think with the variety of parts which some companies sell it's understandable that they can't be expert on every item, I wouldn't expect a mapper to port a cylinder head or build an engine, nor would I map a car.
I can can think of two recent jobs where the mappers took what they were given and made it work, (you know Paul @ RS) he hadn't used an M4 before (god knows how, they're old enough ) and wasn't too keen on it, but made it work to good effect. The other was an old 2ltr 8v I had a lot of input with and did the headwork on, it went to Norway and put out 485bhp and 616Nm on Megasquirt. I have a lot of respect for people who have such talent.
