I have sent an email to Barry waiting for a reply
I have not done any changes to the tunes just asking for an indication of what the values for the 265/65/R17 should be for these tyres
Is the PCM where the odometer sources data?
If anyone is using a BPT tune and has an accurate odometer could you check what values are in
PCM 70E-01-01 BCM 726-12-01
Has anyone using the BPT trans max + CC monitored the lockup clutch current values using a scanguage what readings have you observed?
My readings varied between 370ma (42% lockup) light vehicle load to 610ma (72% lockup) at full load I was expecting a constant lockup current?
First post on this thread, tyre calc states BCM will be;
Required BCM value at 726-12-01 is xxxx-0936-xxxx
Forget about the PCM, it is not listed in the calc instructions anyway and will not change anything.
Change it to 0936 and install the tune, the figure is within the normal limits without DTCs and there should be no reason to change tyre size with the MyCal.
If all is 100% correct then at 100kph cluster you will show approx 96 GPS speed.
From what I have seen you will not see any changes in TCC lockup. At full load especially in 1st to 4 th you will be lucky to ever get full lockup so do not expect it.
My own current tune is a little different in this respect but I still allow some slip at full load in some gears and the second tune in sports mode will never see lock in some gears.
