I have a 2004 coupe F1. It has a new clutch 2000 miles ago. I am taking it to get the trans checked. I want to make sure the Kis/Pis are setup correct. Is there anything I should ask them when they adjust it. Is there a way to set the sport mode a little more aggressive? Thanks Kevin


I will let you know what they say.

Recommended is 4.8-5.3 but I have mine 4.5 and works well. Mike went out with me with the SD attached, adjusting it down to get the best bite.

Get them to re calibrate the gearbox whilst they are there.

Generally speaking it's no bad thing to check / reset the KIS/PIS shortly after a clutch change, so 2K miles on is as good a time as any.

As Matt mentions closing the KIS/PIS gap to 4.5 - 4.8 will give you a snappier gear engagement, which will be more noticeable in sport mode, but if you actually want to speed up the gear change, then this can't be done on the SD machinery. It can be done, but it's really a custom remap from someone that knows the relevant parameters and has a rolling road to check the changes made.

Indeed Miles I am running a custom map on my gearbox ECU and its much much better.

My clutch is on its last legs anyway.

There is a guy here who has set PIS at 1.5. He will take me for a ride someday. He must be hurting his flywheel, but if he doesn't care, why should i? But don't do this on yours...

Matt..what are the real differences with your custom remap?

Don't know Nikos I think he fiddled with the pump pressure to make it run faster.

Like anything that is controlled by an ECU you can fiddle with the peramiters.

Yes, it's faster and yes over 5k rpm it thumps the gears in partly due to running a 4.5 PIS/KIS point. On a later car with newer software the difference would be less. Remember I am running a 2002 model car which did have its issues with its software.

Good news,, Bad news.. All was good in the test results.. My PIS was 4.9. The mech, said that the minimum,,, was 4.8. It is self adjusting,, so even if we made it lower, it would adjust back to 4.9... He didnt want to go lower than 4.8. The bad, is that I am at 80% left... It has been 2500 miles since the clutch has been replaced. If you do the math... I will need a new clutch after a total of 12500 miles.. I drive it in sport mode all the time.. I do, do alot of short local trips... OUCH! I was charged $150 for the check, kind of high. It was ok,, now I know where I stand with the clutch.

The general feeling is those clutch wear readings are not that reliable, so I wouldn't worry *too* much, yet.

Kod...as mentioned by Catman...do not believe what the tester says...

The real test is how the car drives in real. If you only have any clutch slipping, then it's time to replace it.

Agreed with the guys here don't rely on the reading.

Mines at 73% worn done 3 or 4k mikes and its still at 73% worn and does not slip. Do the maths on that and it will last forever!!!

My wear figure between the 2 last services didn't change. Previous readings suggested I was heading towards the first 100k clutch! I still can't work out why the reading is to 2 decimal places. As has already been said, take these readings with a pinch of salt.

I had my PIS point set to the point where the car didn't creep while sitting on a level road. This was to reduce the lazy gear changes and prevent damage to the gearbox.

With your list of cars I assume that you're used to driving a shift gearbox and that you're not holding your Maserati on the clutch while stationary? This, of course, will dramatically shorten the life of the clutch.
