[quote=Adamantium]does anyone know if the mileage in the odometer is maintained by the cluster or by the ecu.
If so, what happens when you put an AIM in? do you need to programme it yourself? [/quote]
cluster me thinks - my AIM started at zero after fitting
[quote=Adamantium]Hi all,
I have decided I’ll be going down the audi conversion route.
With this in mind, part of the problem is going to be the dash.
I am already unhappy with my stock dash so am thinking about replacing it with something like the AIM MXL.
Just wondering if anyone knows if it is compatible out of the post with all the stock audi ecu protocols and also the exige ecu protocol before the conversion is done, as I wouldn’t mind getting it to work now.
does it physically fit in the dash and is it going to be difficult to install at this point? [/quote]
When are you actually getting the conversion done, and which one - 1.8t or 2.0tfsi?
With regards to the ecu, the syvecs is fully compatible with the race technology dash (as I’m sure it is with the AIM). If you seriously thinking about the audi conversion, its probably worth still considering the syves. Could always run it with the yota engine, and then carry it forward with the audi conversion. I believe Greg with his 550bhp audi exige is going down the syvecs route.
Not sure if you’ve got your heart set on the AIM or not, but theres a couple of people on here that are having the race technology dash 2 fitted as we speak.
not got my heart set on the AIM by any means.
What I can say is that the syvecs I was looking in to was the s6, and the audi I’d like to go with is the 2.0 tfsi. Since it has direct injection, it cannot be supported by the s6, and the syvecs version I would need would be nothing like as plug and play not to mention �1800 plus vat minimum. I believe it’s probably the best ecu on the market, but that doesn’t really help me.
The company I was considering for the audi conversion (PSR automotive) are already doing a 2.0 in an elise, and are keen to retain the stock ecu platform. I was hoping to go down that route too for the convenience of the cold start maps etc and the heavily developed stock maps. The stock ecu is compatible with the aim too, but can be remapped to take hybrid turbos and different injectors. It would also save me a chunk of money on the conversion.
Lots of fun decisions ahead.
btw. I read somewhere that the dash 2 is intended for use in race cars having a datalogging module which outputs a can speed signal for road speed. The inputs from the stock ecu read from the abs sensors which give more than 1 pulse per rpm. What was suggested to me was that the ecu beyond 90mph or so is not fast enough to receive the information. The fix was to get the datalogger too, or to insert a gearbox speed indicator (the stock location for celica use does the job apparently) and use that.
Sounds like a faff to me with the aim does it out of the box and I think is prettier.
I looked at both the Race 2 and AIM dashes and due to the plug and play nature of the AIM that’s what I went with.
Also compatible with the Smartycam 
I think you may struggle with setup on the Race 2 dash and as you say the AIM looks nicer. There’s also the issue of getting it to fit right and look nice at the same time which JSR have already sorted
Why do you want to use Direct Injection and the standard ECU???
The standard ECU means you have to retain all of the standard sensors which make the engine bay look cluttered and messy and they frankly aren’t needed in the back of a Lotus.
You shouldn’t worry about cold start mapping these days, its easily doable if you use the right bloke to do it. Modern ECU’s do most of it for you.
Go and visit John and get him to start up the 550bhp car we have in our workshops being finished off. At any temperature, you just push the start button and bobs your mom.
As far as direct injection goes, I also dont see the point in a car like the lotus. Having fuel at serious pressure is just a worry to me, but that is just my opinion. We are not trying to meet any crazy emission regs surely, so what’s the point??
The downsides are the mechanical pumps crapping out when wound up to provide more pressure, plus the lack of injector choice if you want to go bigger.
Sean, those are some very valid points.
I do know that a modern ecu will have next to no problem on the cold start stuff and to be fair, for the use mine gets, I actually wouldn’t be too bothered anyway. I struggle to come to terms with that fact that my exige is just my toy car.
I’m used to thinking in terms of the A3 or the GTR which are perfectly everyday lovely places to be.
Getting into the exige is a fun experience in itself so I should really just stop thinking about it.
The temptation with the 2.0 was that the heads are better flowing from stock, direct injection isn’t just about emissions, it also promotes economy, which is always a nice bonus, but it also gives you greater specific power output through better control of combustion.
I am unlikely to be going far with this car, but a tfsi can be in and running at 400bhp with stock internals with little more than a remap. I prefer this is a forged set up, and don’t imagine I’m going to want insane power. The car is fast enough for me as it is, but I’d like some torque and for the power to be delivered effortlessly without a screaming supercharger killing my ears!
AM not against the 1.8, it’s a stunning engine, loved the several that I’ve owned in their natural habitats. I do like the idea of greater displacement though.
I’ll have a word with the tuners and see what can be done about unnecessary sensors, but I suppose the jury should still be out really.
This thread is not helping me really!!!
But I am honing in on more conclusions.
I definitely want an audi turbo lump in there.
I definitely want the audi 6 speed gearbox.
I definitely want the AIM dash
I think I want the new style dashboard at the same time
I would fit the syvecs ecu if I go for the 1.8t.
You can run a safe 350 bhp from a 1.8T on standard internals and you can pick up an AGU code one for about �300, the six speed box for �300 and an Emerald from me that is already set up for the Audi for �475 
You will always want to go higher power at a later date, so why not save money for now, then not waste any when you upgrade later?
I also have the exhaust housing from one of these turbos…
http://www.jabbasport.com/store/index.php?app=gbu0&ns=prodshow&ref=OD1708
and a jabba sport exhaust manifold for it to fit to.
wow, low low prices!
Does the jabbasport manifold for the gt series turbos fit the limited space engine bay that the lotus will have?
I would imagine you need custom manifold and exhaust set ups due to the constraints, and from what I remember of the jabba sport manifold it is a funky one of cast they have had made for the stock application?
You don’t need a custom exhaust and the jabba manifold and turbo can be made to fit with a slight bit of modifying.
I have some spare engine mounts and drive shafts as well for an S1 elise.

I think you’ve been told wrong about the Race Technology. The latest ones are plug and play just like the AIM - they bascially just take all the info from the OBD port. Worth giving race technology a call - very helpful indeed.
Should of saved yourself some dosh and bought yourself 120bhp S2 elise if your planning all this work
In fact, I have all these parts…

Nah, did think about that but I got a great deal when I bought the exige. It came with a load of parts I’d have to buy anyway.
Like for like, for the same year of Elise I am probably only in for about �5k more than I would have been. For that I got thr exige bodywork, Ap brakes, nitron suspension, a charge cooler and track spec seats with harnesses, twin oil coolers adjustable antiroll bars, uprated rad then there’s the 240r wheels too!
Then factor in that I have a 111R engine with baffled sump, supercharger, pulley and supporting mods for 320+bhp and a 6 speed gearbox to sell/ part ex, and I am still better off.
Aren’t those all S1 bits so no good for a yota powered car?
[quote=Adamantium]The lighting in mines driving me mad. It’s non inform across the clock face so I can’t see certain parts of the sweep,
Basically 9 until 11 and 1 until 3 are dark.
Trouble is that Francis describing other problems, and my eyes do struggle changing focal lengths quickly (long sighted glasses avoider causes the sphincter muscles in my eyes to get more tired than they should and hence struggle with focal length changes). [/quote]
Sphincter muscles ??? Are your eyes in your arse ??? 
Yeah the driveshafts are for an S1 so no good for an S2 car.
I dont know who’s engine mounts they are, but they wouldn’t fit an S2 either. Or the gear linkage.
yeah it’s all old s1 stuff
The AIM dash contrast/brightness is a complaint AIM are aware of since I spoke with them yesterday and they are working on a brighter unit for the future…
If you are serious you need to mount it at the base of the windshield without the sunshield…
Cut the boot out of your exige if it’s a track toy and heat won’t be an issue allowing a proper header design and less chance of burning down your car…You will need a place to mount your extra cooling once the power goes up and the boot is the place for it…
Pesky you might as well mount those extra guages in the passender foot well…
