Lou,
The 4.8-5.2 related to V1 ECU....If you did get the red transmission symbol....The fault will have almost certainly been logged in the system memory, so if it is a concern for you, have the dealer run a diagnostic, and they should be able to tell you what happened |

Thanks for the info. The car is smooth on the 0-1 and 1-2 upshifts. I did get the trans symbol and beebing once after some low spped crusing in 4th which never happened before when the pis was set higher. I've got 14k and 6 track events on the clutch and the dealer said it has 'plenty of life left" Some old post said the normal range is 4.8-5.2 which was why I was surprised when the dealer said 3. |

Hi Lou,
Got your email.....You're right at the limits of my knowledge here, so please don't take this as an authorative answer.
The good news is that you have V2 of the ECU, so any adjustments that you want to make are easy to do. I believe that the numbers are a physical measurement (in milimetres). The higher the number the greater the allowance of slippage (smoothness), but also the greater the clutch wear. Rather than get hung up on the actual numbers, How is the car driving? If it's set too low, the car tends to be difficult to maneuvre at slow speed...It'll be difficult to apply the gas smoothly you'll get spurts of power, and the whole affair gets jerky. It's possible thru setup to balance the speed of change 'v' smoothness of change.
I tend to judge whether the car is set up nicely, based on how smooth the car engages 1st gear when setting of from a stop. Also, 1st to 2nd gear can be very jerky/prolonged if the transmission isn't set right.
I presume that you aren't getting any clutch overheat alarms when driving in 1st (a really annoying beeping sound)

I just had my 360 serviced and I think I heard correctly that they set the pis (point of initial slippage) at 3. I have the V2 ECU. This semms low compared to some threads. Does anyone know what the recommended pis setting should be? What exactly does 3, 4 or 5 mean? 4 what? percent of something or an actual mechanical measurement or just a relative number. What "point" does it measure? Does a high pis give more or less slip? More jerky or less jerky. Thanks in advance for any info. |
