4L60E control settings

[VL400]

It has not been defined in the XDF thats available. Its also different in the electronic autos and is no longer called PPK. Its now a ratio which is calculated using ... Ratio = (Tire Rev's Per Km x Diff Gear Ratio) * 28


EDIT: XDF has now been modified and can be found here https://pcmhacking.net/forums/viewtopi ... =5&start=0

Ok tells me the ratio is 44134.00 when i open the bin is that right ? or do i just change it's value higher or lower if it goes from a 3.08 diff to a 3.79 ? and see what happens.

[VL400]

Yes 44134 is the standard value. Use the formula to work out the value you need...

[Dec_head]

Thanks for your help but me being a dumbass it went straight over my head maths is not my strong point
44134.00 divided by 3.08 wich is a standard vr v6 ratio gives me 14329.22077922
if i x that by 3.79 it gives me 54307.74675324 is that how i work it out .

[VL400]

Sure is

seems this great thread was abandoned without any tweaking having been done, i found the GM 4L60E book here http://www.scribd.com/doc/40008572/4L60E-GM which has diagrams similar to delcowizzids and a load more other stuff.

Other than Shift points i have tried changing desired shift point time around but didn't' seem to make any difference.

I have done some reading some people say the adaptive shift feature is bad and should disable it all and some say it's good.

I figure since feb 2010 someone would have done some extensive tweaking on this?

[Holden202T]

other than shift points i've played with shift times, also adjusted the line pressure v's kms etc and that in itself can make a stock box shift alot firmer!

can also change pressures for performance/normal modes too so i made mine normal untouched but performance mode firmer like a stage 1 shift kit!

[The1]

so your talking like the 2nd,3rd,4th gear pressure offset vs tps? youve just raised the psi a bit?

[Holden202T]

Changing these does any gear (speed dependant)

Normal Mode - Force Motor Pressure (PSI) V's TPS & KPH
Performance Mode - Force Motor Pressure (PSI) V's TPS & KPH

and changing the other ones you mention is for certain gear and mode as per label for each item - BUT they are offsets, so that add or subtract from the main table (subtract via negative numbers)

i found this from somewhere, not sure if anyone has this yet?
