Well my trip to B5 yesterday was a bit deflated as I was hoping I had a good car as I had tried hard to make it as good as possible in prep for this mapping.
Turns out I was driving a bit of a time bomb oops. Got to B5 and the guys got to work first off was a smoke test which went well albeit a slight leak from the TIP adapter.
So once this was done they moved on to strapping the car down on the rollers to get an idea of how it was running. This turned out to be a bit interesting as my car was running ala a diesel (Whoops) so figures were interesting as I was getting 30psi and about 320torque!!!!!
So a bit of fault diagnosis was needed and Paul (Tuffty) Mark and Bill started to try n work out what the hell was going on.
First issue that was found was that when I fitted the new fuel pump the return fuel line had got twisted and was stopping the fuel returning to the tank so instead of 3bar mine was getting 4bar. This was fixed (mmm the smell of v power) and we moved on.
So the mapping process started and things were looking better but another issue cropped up as my smallish FMIC just couldn't cope with the heat the K04 produces when pushed and my Pre cat lambda was giving a few issues too.
Finally managed to get a good compromise on the balance of heat and fuelling and got a figure of 265bhp and the same in torque and its defo quicker than its been before in any of its previous setups on the revo software.
I am happy with the results (even though I was hoping for more) as the car was in a dangerous way before and I was lucky it had held together as well as it had.
So the conclusion is I need a bigger FMIC to cope with the heat and possibly a new pre cat lambda sensor.
Today I have already actioned this a bit as I have re-sealed the TIP adapter to try and eliminate that leak that was found and also removed the pre cat lambda for inspection. It was pretty sooty so have cleaned it up in the hopes it might work better now its clean.
I am gonna search for Intercoolers I think I can use and this will be next job as once I have done this I can do some logging to show Bill to see if the heat issue has been rectified and the car will work any better.
All in all it was a good day and my thanks goto Bill, Paul and Mark for there good banter and lots of great info plus of course all their hard work.
