Kevspec Posted January 29, 2021 Share Posted January 29, 2021 Hi I'm just wondering for manual mode in the zf can I completely eliminate kick down shifts via the tune just to help from killing the trans. I know there is a detent switch u can feel but would like to have more control without having to think about it Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted February 12, 2021 Share Posted February 12, 2021 This is one way to prevent kick down ZF00117 "Minimum throttle value to detect kick down" Set this to 100.4 Quote Link to comment Share on other sites More sharing options...

You could set this to a very high number. When I'm in the office I'll try and find it for you. It is in the ZF tune itself. The only other optioned I've seen is play with output speeds in manual mode Quote Link to comment Share on other sites More sharing options...
BeerTurbo Posted February 13, 2021 Share Posted February 13, 2021 ZF shift table 27 from memory, remove all the highlighted downshift figures and it will just stay in whatever gear its in. ive got mine setup something like this, so it wont ever downshift for you..... but it will upshift somewhere verry close to limiter. Just incase your reactions are to slow / rest your hand on the gearstick and move from performance to manual mode without realizing. cheers Quote Link to comment Share on other sites More sharing options...

Now I suspect you may find that this will not stop kick down for example if you try a launch in second on some cars. We have not worked out why this happens (two identical territories both with 77DA, one would kick down from 2nd to 1st on launch, the other would not). There is a work around for this but it is only available in the Workshop version of the PCMTec Editor and completely disables kick down. I worked with Stathi from IMS to resolve this issue so if someone wants the information then they will need to contact him. 1 Quote Link to comment Share on other sites More sharing options...

Darryl@pcmtec Posted February 26, 2021 Share Posted February 26, 2021 Shift up, no. Shift down it will at, approximately, the specified Output shaft speeds Quote Link to comment Share on other sites More sharing options...
G6ETURBO Posted February 26, 2021 Share Posted February 26, 2021 Is there a table that will shift at a specified output speed in manual mode. A friend of mine has it setup on his xr6 which is done on SCT. So I can imagine it would be here just not sure which table. Quote Link to comment Share on other sites More sharing options...
Darryl@pcmtec Posted February 26, 2021 Share Posted February 26, 2021 That is the table, 8000 is a speed it will not reach so it wont shift. Lower it to the point you want and it will shift. You will need to experiment with it as well as there are bigger errors in the lower gears and you have to put it lower to achieve your shift point.

Kevspec Posted March 13, 2021 Author Share Posted March 13, 2021 Update finally got a chance to try that file supplied and works perfect as it should. We also turned off convetor lock up under 75 kph and car is so much better to drive Quote Link to comment Share on other sites More sharing options...
yoda598 Posted March 16, 2021 Share Posted March 16, 2021 if you dont mind me asking, how did you turn off the lock up? Quote Link to comment Share on other sites More sharing options...

Puffwagon Posted May 21, 2021 Share Posted May 21, 2021 I did this today and the car still kicked down from 4th to 2nd on the dyno. Quote Link to comment Share on other sites More sharing options...
