V8 DNA 4thirty

i'm re using bits of mine Ollie, you going to JAE?

[OlberJ]

Afraid not man, moving home this weekend and the Mk1.6 is off the road this week for a strip down and rebuild.

Saying that though, might be the perfect re-run in to take it down to JAE next weekend. Hmmm.

Visited DNA today and laid some hard earned cash into their hands, should be able to pick up the panels when I'm top in the queue.
 Even though I've spoke to the guys on previous occassions they still had time to chat about the kit and my requirements, whilst working on a number of cars in the shop.
 I Should have a finished car for Stoneleigh.......
 Picked up more advice on my chosen colour, which I may change again

Carried out some more work on the car today, stripped out the fuel tank, all pipe work and electrics around the new engine bay extension, then set to it with the grinder

Sourced a gearbox and bought a lathe

Shit, thats one hell of a hole!
I thought I was the MADMAN    cant wait to see it completed, keep it up Darren.

Keep it going darren,looking good  on the width although you may want to cut a bit more out of than that to get it to fit on the height, so it looks a bit like this.

This is the first rough cut before all the trimming takes place, I need to cut more off the top for a straight shelf, and sides for access.
 Paul I like the mounting of the ecu, I was wondering where to put it for minimal weather and temperature intrusion.
I notice you've left more room at the front, I propose to mount it as close as possible with a vertical centre cover plate in between the seats allowing all fluid and air runs up this channel although it's only a thought.
 I've twisted the gear cables all over the place and they're still free moving, I may run the new ones under the car, I went to snetterton a few years ago and was lucky enough to have a go in a GTA looking kit with a ford cossie lump, the gear linkage was too complicated but the cable run was extensive, gear change still felt very precise, so I'm not too concerned with it just yet.
I spoke to the gearbox supplier and he's willing to part with all the 'useless' bits in the deal. With the V8 ring gear plate, diesel flywheel and clutch I should have enough info to fab up my own billet steel V8 flywheel.
 Work is crazy at the moment and I'm being kept away from my own project, one day a week is not enough!
Looks like you've come a long way in a short time. Any more pics to wet the appetite?

For teh ECU. I'm running from the old bettery position and re positioning the battery, its a fairly damp place, but I'm sticking it inside a rally bag, so called as its used in rallying to protect the ecu's, so should be good for the job.

All fits in with the roof down

Quick question, does the speedo take it's signal fron the ABS on the MR2?
 And have you sorted the ECU with your VAG technician?

[paulm]

The speedo signal comes from the ECU same as the audi it takes it electronically from the gearbox.  Most ECU's need a speed input to reference and compare, from there it will go on the can bus over to the instrument binnacle.

Looking really good m8 :-) When I was playing with the speedo pulse on my DNA I found it to be around 3 volts and it pulses at a ratio of 1:1  ie.. 60 pulses = 60mph found this out when I was doing a working concept on some electrics for my murci kitcar.. http://www.youtube.com/watch?v=4ZEpdilqG-U

[paulm]

Steve, Was that a square wave pulse 0v low and 3v high ? Over what time frame ?

Cheers

Paul

[CdRsKuLL]

Hi m8,

Yes Square / on or off pulse this was over a time of 1000ms cycle. 1 pulse = 1mph it seemed. It was between 3v and 5v.. I cant remember. I was going to put a protection 5.1 zener diode in just in case anyway. I was using a arduino device connected direct to the speedo pulse wire measuring the pin. Maybe you could using something similar to convert your input signal.

Cheers Steve,
I'll scope off the back of the audi ecu to see what comes out of the box
