I'll be trying the 80mm to start with, hopefully it won't give me any issues. Greig has an r32 tb which if I remember is 75mm, I may see if I can try that if the 80mm gives me problems.
Any updates on the beast.
erm.... i bought Tax for it today. does that count
ive been far too busy recently to anything on it at all. ive driven it once in 14 days
By the sounds of his location he is to busy with Wiko
thanks nick....
hehe, ive driven the car two days running
today i had some time to do a couple of logs to try to get to the bottom of the overfueling problem.
im actually none the wiser, EGTs seem extremely low. i cant remember what i should expect for the placement of my sensor. they seem too low???
All runs in 4th and using B6 T6.... awful timing advance.
No RPM here but obvious whats going on..... All runs in 4th

There's something wierd going on.

Nick, they've been in a few weeks but I've hardly driven it.
Dave, it is about 2" from the downpipe to turbo flange.
John, I'll try to do a run tomorrow (today now) I was really amazed to see the figures. When you said about logging EGTs I thought that had to be the cause. What we don't know is what the Revo code is looking for with that placement. Hopefully Kev will look at this.

I thought that Carl, but we don't know how much fuel they are putting in as the sensor only reads to 0.75
edit: we know (if they are 550s) how much they are putting in but we don't know how rich it is. It could be bogging down but it doesn't feel like it.

Maz, apologies for not getting any day time pics up. We havent had a dry Sunday since you detailed it
any luck on the catch pot?

Things are looking better though as the map is requesting much less fuel( 0.79 as opposed to 0.65) previously. Any chance totalvag could swap out the lambda and egt probe to rule them out of the mix.
If the lambda was under-reading (seeing lean) , it would try to put more fuel in. But it's not - it's seeing rich.
Check my facebook mate I uploaded pictures there. Should give you an idea of what its like. Can you believe I can find a ruler in my house!Maz, apologies for not getting any day time pics up. We havent had a dry Sunday since you detailed it

I can ask Greig if he has some but as dave says I think there must be something else wrong.
If the sensor was faulty and under reading it would take fuel out. If the EGT was under reading I don't think that would add fuel either. What could make the car add fuel like that?
Injectors too big... It is removing fuel -4% if I remember but it would at 0.75
high egts
faulty MAF
faulty MAP
fuel pressure too high
faulty lambda
I'm going out for a meal tonight but hopefully i'll be in a fit state to do a log tomorrow. Are there any other blocks we think would be handy to see?
Maz I'll go and have a look now
