Bye bye clutch slip

[muddyboots]

As some of you know, since getting my Passat remapped I've been suffering from the dreaded clutch slip as many tuned PDs do. In this case it was anywhere between 2-3k rpm in 4th/5th/6th, even with light throttle application.

I asked Simon Coe to get me a revised Upsolute map, with slightly reduced torque between 2-3k rpm, but with a stronger top-end (without increasing boost any further).

Simon uploaded the new file on Friday, and I can now put my foot down at lower RPM in any gear without worrying about frying the clutch, but when accelerating hard at higher RPM I now have a bit more power than before.

Anyway - I know that a lot of people suffer from clutch slip but either can't afford the expense of an uprated clutch after forking out for the remap, or just don't want to go that far.
I thought I'd post up to show that if you choose a decent tuning firm, they should be able to cure the problem for you, with hardly any noticeable effect on performance.

At least I should be able to get a decent rolling road run at Awesome without the clutch slipping now

Good news. Similiar to my map then.

Good news. Cheaper than an uprated clutch for sure.

I also think that by reducing the torque spike, it's less likely for the wheels to break traction - so although I have slightly less torque, it could actually make starts a bit quicker if the TC cuts in less....

glad you got it sorted lee. another good upsolute report i see

I'm thinking about changing my remap for the same reason. Whats the poin of having all this torque if you cant use it.

The way I see it, when I want most improved performance is when I'm accerelating hard - which uses the upper end of the rev range where high torque and clutch slip is not an issue.

Do you still have the same amount of power now you have had the map changed? just that all the power is now at the upper end of the revs

Top end power is not affected, the map was only backed off between 2-3000 rpm. I did ask for 20-30lbft to be knocked off - could probably have got away with less of a reduction but I wanted to be 100% sure of curing the slip - and you can notice in that rev range.

However at the Awesome RR day yesterday, I still managed 270ish lbft torque, and ~175bhp @ flywheel, so it's not low by any means.
