Hi MS, Yes I think Enzo may have dome this also. Did you have it delivered like this or did you return it for the more aggressive settings after having tried it?

Oops, just seen this. Yes, I returned mine to have the more aggressive setting.

OMG!

I didn't think driving could get any better, but fitted a DBW over the weekend and it's like a completly different car.

I was thinking that it probably wouldn't make THAT much difference so I opted for my first outing on the most aggressive setting. How wrong I was, it is fantastic, even on the slightly less potent setting it is still a wonderful modification and I don't know why I waited so long.

SOunds like you are are having a ball Davis.....Car still looks great in your pic....

hmm decision time - someone tell me about this pis setting thingy wassisname. Does that make the change quicker or have i totally got the wrong end of the stick? and if it does how effective is it compared to the FD DBW? Would I be better off FD ECM and PIS?

While I'm on is it an order from the states job or is there now a UK distributer (or both)? sounds like it can be a see fit job - especially as i guess mine already has the cut loom!

Sorry - lot of questions, but i do like to make the right choices when it comes to upgrades!

Just so happens Grinzzz ive just sold the DBW that came off your car , had the aggressive and very aggressive settings , there is a UK distributor on one of the Adds at the top of this page , just keep refreshing the page untill Performance Italia shows , guy who owns it is called Noor, great chap and very helpful,


The pis and kis setting will reduce the time taken for the clutch to bite on the pressure plate, normal and most common setting range is 4.7 to 5.1 , my own has just been set to 4.5 which fractionally makes for a faster change , and at the same time a very positive pull away ,

Typical, my timing stinks!

Did you try the DBW? how does that compare to the change in pis/kis (I'm sure it works better in italiano!)

 

[Mr.Cambio]

Loz, at the official dealer here (who is not a reliable person, but anyway) i'm told that it's not recommended for the PIS to be set under 4.9. Have you been told the same? (I indeed want it to get lower, too.)

The accepatable quoted range by Maserati themselves is between 4.7 and 5.1 , that being the distance between clutch and plate , Ferrari 430's are set at around 4.0 but have additional software programs to cope with initial contact and power take off , when i had mine set at 4.5 it was with a new clutch and bearings etc, done by Dick lovetts and i had good communication with the tech who was doing and testing it , definately had no adverse info from him , in fact exactly the opposite , it was he who informed me of the 430 set up ,

A definate improvement on standard formatt but still not as fast as the DBW , reason i sold the DBW instead of fitting it was that the car will be going up forsale sometime in the near future and i'd rather have it standard for selling purposes save having to remove the DBW come sale time

Thanks, useful to know.

The PIS setting on your car is 4.97, which is reasonably aggressive but I have heard of people going as low as 4.5.

You will find variations with car and with driving style also. When I had the Rame I really felt I needed a faster gear change but I don't feel that in my current GS. However, the throttle feels a little 'lazier' this time round, which I didn't notice in your car.

 

[Mr.Cambio]

If i'm not mistaken, the PIS controls the gear engagement, the DBW controls the gear change, right? WIth the DBW i didn't have improvement in the engagement( very aggressive mode only). How many kms have you run after the cluctch replacement/PIS setting at 4,5? ( you put the devil inside me!!).

And Loz also!

I deliberately had the tech do 20 miles at a 4.7 setting from initial installation , car went back into the shop and Pis was reset to 4.5 and then he did a further 30 miles to make sure all was ok and then all the print outs were done and parameters were reset

Since then i have done 500 miles including one exhilerating trackday in wales , and im rather pleased with the results so far

cheers, the change is a bit slow compared to the other two I drove. Luigi obviously needs some redbull to speed him up a bit. Wonder what the cause is?

PIS or point of initial slippage is the same as (but in reverse) as KIS or kiss point - the point of initial engagement. This is a distance measured in millimetres. The shorter the distance the quicker the (dis)engagement, as the clutch is travelling at a fixed speed over a shorter distance. The shorter the distance the more abrupt the (dis)engagement as you're reducing the 'dwell' time / distance for the clutch to engage fully. This is thought to reduce clutch wear, and I can follow the logic, though I haven't come across or heard of any measured comparison.

Going below the minimum of 4.7mm, though probably not recommended in official circles, seems to have proved okay to do. I have heard the same comments as Loz in relation to the F430.

The FD DBW module is a throttle remap. It changes the way the engine responds in relation to particular throttle inputs (itself a DBW system) through the throttle potentiometer / pedal. Anyone running the FD DBW (particularly in aggressive mode) will know that in first gear, the throttle is VERY sensitive under foot, this is because it has been re-programmed to give a much steeper acceleration curve compared to throttle input. Now at this point I have to say I haven't quite got to the bottom of the programming yet, but my understanding is that as a consequence of delivering acceleration from a shorter travel on the potentiometer, this in turn delivers the quicker gear shift only otherwise available at much higher revs - happy to be corrected on this point though.

Additionally I haven't got to the bottom of this yet; but my understanding is that on the pre MY'05 face-lift 4200's there is the setting for PIS / KIS, however on the later MY's and the GS, the PIS / KIS is also accompanied by a mechanism to constantly monitor and reset the PIS / KIS as the clutch wears, so effectively it resets itself to the chosen distance, whereas on the MY'04 4200's and earlier, the PIS / KIS has to be reset via the SD2 as the clutch wears. This is usually done at service.

 

[Klive]

Further to the PIS points above, if the setting is too low then the clutch will not totally disengage when changing gear, thus you're risking gearbox troubles.
One way to identify this is to sit in first on a level surface and see if your car pulls forward. If it does then the clutch is rubbing.

 

[Mr.Cambio]

I will make a try to set it lower..Soon i'll go in for a new clutch..
