Tuning turbo time!

yeah it can rev to red line easy...
if i slowly roll the throttle on then its fine but if give it some it will miss... sometimes it will miss really bad and make you look like you cant drive.

ooooh and its worse the more people in the car.

Put an update on the msextra forum.

Run some composite logs at idle. I think you may have a config error with you trigger edges

My punto gt does this exact thing but only from cold get a huge jerk when you change up a gear like your a muppet that can't change gears. Revs fine when pedal pressed progressively but coughs and splutters if you just whack your foot down...

that sounds like a boost/vac leak chris lol. that wheel of death looks scarey lol.

maybe something to do with the fact that you shouldnt be flooring it from cold? :idea: As Whiley said, sounds like a boost leak.

That wheel of death looks fecking dangerous

I still reckon its noise related. Are you sure the clock crystal is in the ms2 card? Cos i still remember fitting and testing mine to the main board itself...

you remove all the timing stuff on the v3 pcb when you go fully sequential

right i'm off topic still but i must defend myself.. I NEVER drive my car hard until properly warm - not even my NA cars!!! And this problem is not boost related, its really low down the revs before it even comes on boost - could be a vac leak hence i have metres and metres of vac hose ready to go on. Its from tickover, press the pedal gentle and she is fine but if you stab at the pedal it misses and sputters but is ok once any kinda heat is in the engine, 100 metres down the road and is fine which is why i think its more likely not vac as they wouldn't stop leaking when car warms up... Car does have a boost issue as well, which is not related and very hard to describe - but i suspect a vac leak or hair-line crack somewhere on turbo/wastegate/inlet, just somewhere.

Fixed it decoupling capacitor was to large... basically at high rpms it was smoothing out the pulses from the crank sensor

 

[craigk]

great to hear you got it sorted, now i think where in need of a vid

 

[craigb244]

ill get one asap. roads have been wet and driving it at the moment is not to nice. Only need to tap the throttle in anything but 5-6th gear just causes wheel spin and the car heading for the curb!

 

[craigk]

haha love it mate, torque monster...did u fit lsd?

 

[craigb244]

Feels like been on lsd

but yeah LSD here. if ima spinning ima spinning both lol
