Selespeed F1 transmission improvements from 1999 to 2008

Are you SURE your PIS is adjusted to spec? 3,000 RPM seems a bit off.

IIRC the F1 system doesn't account well for leaking hydraulics and variation due to wear..

 

dang 3000? i thought mine was bad at 2k rpms

 

3000 rpm, I agree something is not right.

 

The 360 uses Motronic 7.3.1 and the F430 and variants use Motronic 7.1.1. The TCUs will not be compatible.

There are tons of threads on the 360 and CS TCUs. The last 360 TCU was introduced in the 2002 timeframe and the CS TCU in the 2003 timeframe. Either of those should work great.

Take your 360 to someone who knows what they are doing and have the system bled and fluid replaced (should be done every 3 years), system self test run, leak check performed, and PIS optimization done. With the late TCU in your 2003 360, that should fix your problem assuming there are no hardware issues. A good tech can set the PIS just above the point the shaft is moving and that should make for a dramatic difference in what you are seeing now.

 

Beats me. I bought my techs AutoEnginuity software, but that is around $3500.

 

PIS is what? My 2002 Maserati coupe Cambiocorsa is quite rough when shifting down (the revs don't go high enough when downshifting before the clutch engages). Also, the revs goes to 1200-1300 rpms before the car starts to move... that means it becomes quite fast before the clutch is fully engaged and I suspect that to wear out the clutch much faster which is not what I want. It becomes stressful to drive aswell in stop and go traffic. And the throttle is hyper sensitive. 1 mm. of throttle and the revs go up to 1300... my 2001 BMW M3 SMG is smooth as silk and engages softly just above idle. I want the Maserati to be like that too! Thanks for input.

If the Maserati does not have an e-throttle, it will be like an F355 where the throttle does not have enough authority to match revs, especially on downshifts. Actually need to heel and toe to get matched downshifts and let up on the throttle slightly to get smooth upshifts if that is the case. Even on Ferraris, using Normal in a 360 or Sport in an F430, there is no rev matching on upshifts or downshifts. Not familiar enough with the Maserati to know exactly how the Selespeed system works on one.

 

Based on other postings, the Android app that you're referring to has a bug that doesn't allow a decimal number entry. That makes it useless since a difference of 0.30 on the PIS adjustment is quite critical. BTW, my '03 Spider engages at about 1,700 RPM.

 

My 2004 Spider does the same damn thing. I had Ferrari of Atlanta do the fluid, look the system over, and they said PIS was set correctly.

 

My 2003 F1 engages nicely on take off. Haven't looked at the tach but I would say slightly under 2000 RPM. I've driven 6 speed sticks (911s) prior so it took some getting used to to get the feel of the F1.

I don't punch it on take off (and with me keeping it in "sport" mode it breaks loose pretty easily if I do) and I find once engaged on take off shifts are really nice. The accelerator inputs work nicely as when between shifts and driving in traffic a very, very, slight lift on the pedal results in a super nice positive shift with no slipping. And of course with the car underway and the pedal to the floor the shifts are about as positive as they get.

So I have to agree your '03 slipping up to 3000 RPM on take off has got an issue.
