Hey Guest one of our sponsors Progressive Parts is running Black Friday and Cyber Monday offers - more details here
I've managed to fix the lumpy idle that my car was experiencing.
I was giving my engine bay a once over whilst it was running and noticed a hissing sound from the fuel rail area. Turns out injector number 3 was leaking air past the seal at the manifold.
I removed the genesis seals that came with the injectors and swapped them for VAG seals which seem to be very slightly larger in size. The air leak has now disappeared and consequently the idle is now perfect. Backfires have also been reduced, now mostly occuring at warm up which I can deal with and control.
So essentially I guess my build thread is finished (for now) as I'm happy the way the car is performing.
I think I'll head over to JKM at some point just to compare rolling road figures after fitting my new engine mounts when they arrive.

Good idea to get a seperate rr done but be prepaired for the worse ( as you know what happened to me )
mork you say the 3bar map sensor is from a diesel but isnt it from an rs4?
whats yours from bill?
whats yours from bill?
bill, the 3 bar map sensor you wrote the P/N for in post #133 is it a different size to the original one? the sealing part i mean?
ive just got mine and it dont fit

There are 2 sizes of MAP sensors see http://www.42draftdesigns.com/categories/products/18tmap.htm for info

fitted right in mine. there are two std sizes tho, and some pro-alloy fmic's were made for one of them but not both i think i remember.
pro alloy made a one size yes as mine was different to what they done think it was somethingt to do with pre 52 reg cars
Bit of an update. I decided to purchase one of Racelogic's traction control kits for those wet days. A little bit of an impulse buy really, but I'm glad I did, all I can say is WOW!!!! It really does what it says on the tin. I'm very impressed with it. Calibration was a simple process of finding a straight piece of road with a 180° SLOW bend onto another straight. Took 5 minutes.
Now I can put my foot down and it grips in all gears.....very satisfying as the car launches off. I'm still playing with the settings as you can adjust minimum speed threshold, slip override for straights, launch settings etc.
There are 4 sequential cut sequences with increasing severities of fuel cut depending on the amount of slip detected. Very smooth and progressive.
Launch control sounds awesome with all the pops etc.
I can't wait for it to rain to see how it is in damp conditions.
The kit:
Here are some fitting pics for those who like to see things in bits.
Extending wires for injector cuts in the drip tray:
Route into cabin + boost gauge vacuum pipe:
Finished injector cuts. Used plugs so I can revert to standard if required. Also sealed with silicone to stop water ingress (not pictured):

Location of ABS wiring:
ABS connections for wheel speed input:
Finished connections all taped up:
Diagnostics/programming/logging port with test light in glove box:
Brain fitted next to fuse box:
Location of selector switch. Temporary mounting solution. I'll change this when I think of something better:
I should be picking my new engine mounts up today as they've arrived in the country. I'd post pics, but everyone knows what they'll look like!

Looks tidy. Been looking at this myself. How much was the racelogic kit? Did you go for all the options? How long did it take to wire up?
