Newbie with a serious tuning disorder.

Well we're looking at more wizardry this Saturday, Scott John and a spare Z4 will be involved. I'll just let get on with it.
I've been looking at the drivers seat cushion and decided to replace it, so stripping the seat down is rather tedious job. Once I'd stripped the base I then thought the back was rather tired as the foam was starting to break up. So now I have a new one arriving Saturday at a cost of £125, that now puts my seat refresh at £255!
It looks rather drastic when dismantled but it isn't to difficult to do, just take your time and it'll all go back together.
 
Bloody hell, that base is knackered - how many miles are on the car ?

I've always thought that having a spare set of driver side inserts would be a good investment if your car is a keeper, as eventually they'll be impossible to get and then you'll be looking at a custom job... Many more £££s

Hope the wizardry goes well :thumbsup:
 
The back insert was the last in the country Bing, I not sure how scarce they are just yet, but they will at some point. As for my mileage its 79k, the seat base has actually collapsed at the rear and the bolster has started to break up around the steel frame.
 
I think I'm going to buy a back and a base as soon as I can afford them - if I sell the car before using them (not planning too, but you never know what will happen) then they are something I will always be able to sell on at near RRP.
 
i do love an update haha! fingers crossed all goes well over the weekend and u can update with some more pics as and when :thumbsup:
 
The wizards have been and gone, regrettably without a resolution! Next plan of action is remove the steering column and see if there's an issue with it not working. If ok we're looking at finding a way of powering it up on the bench with can signal from wizard no2. Wizard no1 possibly has a way of testing it with proper test equipment.
What we're thinking is find a way of powering the steering and using wizard no2's black box of tricks we can run the dash with all the can messages for it to work.
Wee pic of testing today
 
Praise the lord! Tonight I've been blessed with the assistance of power steering, which without the help of Billy's donor car probably would've have happened( cheers again Billy).
So to up date members I've pulled Billy's steering column out and replaced it with mine. I had to remove my key barrel and swap them over as they're all coded together with ecu. My column just clicks twice in Billy's car but no assistance whatsoever. So with Billy's sitting in my car and plugged in to my harness and wizard no 2 box's of tricks sending can signals we have a solution. I still have the problem of there being a problem of my column not functioning, but that's still to be resolved.
The bigger picture here is that what we've achieved is that with John's box of wizardry you can transmit can signals to control the numerous control modules throughout the systems. Now just need to figure out what to do about my dead steering column?
 
So you're keeping the z4's EPS but you also have a donor car? (and swapping out the columns to test?)
This is not an easy build!
(the breakout/testboxes showed that already that there are some huge electric hurdles to take)

There is no donor car. Steve borrowed somebody's steering column.
 
Wow good work. I bet you cant wait to have this finished!!! Good luck Steve :thumbsup:

As a thought (its something i would like to do) But could you not have ditched the electric assisted rack and put a hydrological assisted one from an M car??

Yeh your right I pulled one out of a mates car to try and see if mines had a problem.

You better believe it Mark, there's a whole lot of sunshine heading my way. To mark the occasion I had a couple of red wines with dinner, and sat all night with a grin on my face. Even my better half kept asking how the power steering issue was progressing, she obviously knew it was doing my head in.

I often wonder if it'll ever be finished, I seem to keep meddling/ improving my projects.
When I started to think about my project I did consider hydraulic power steering, but they are fairly bulky and I'd struggle to run it thru the sump pan. Cutting the pan wasn't an option, don't like robbing the engine of its required fluids. Swapping to hydraulic from electric I thought would also create problems with the control modules in the car. Now knowing how much grief can bus systems are I'm sure I've went the right route, and look I now have a can bus Wizard able to trick BMW's into thinking they're factory.

Your right this has been a real mission to solve, but with the right heads involved anything's achievable. I now feel I've only just got a grasp of what can signals are all about. When I spoke to the software technician at Race technologies he said I was probably the only guy in Britain trying to do this. He even didn't know where to start and only offered a bit of kit that would possibly send a static rpm signal to trigger steering. Wizard John has created what I would call is a bespoke control module even BMW don't have.
