11p 4l60e kick down

Post by vp304 »

Thanks to you guys my cars running great vr commodore l67 swapped on 11p.

What i would like to do tho is around 60 - 80 kph the kick down is a little lazy say put your foot down drops back from 4-3 but really need to press the throttle not full throttle but press it a bit to say to kick down to 2nd gear etc.

Would moving up the downshift tables below from say 50 % to 100% all down one spot (So the 50% values are now in the 43.75 cells area)
Make the trans a bit more lively want to kick down a bit easier? (referring to the A/T Normal mode - downshift - KPH vs TPS )

Also the 2 settings for kickdown downshift in the 2 separate small boxes (bottom of picture) below in my picture do they work like this
If i press over 94.90% throttle tps
The trans will do a down shift from 2nd say back to 1st as long as i am below 47.50kph ?
It kind of overrides the A/T Normal mode - downshift - KPH vs TPS table ?

You could lower the TPS Threshold Percentage to enable Kickdown, that will make the transition more sensitive.
Also bring the Downshift figure in the target area closer to the Upshift figures.
Good to see the cold start issues have been resolved :)

Cold starts are great now thanks for your help on that.
So i was kind of on the right track with moving all the cells up one on the downshift map table. thanks quip4it

Played with the kick down settings and car feels a lot better with them set like this below.
The compare values are the 11p default values
