rfh Posted October 27, 2021 Share Posted October 27, 2021 Hey guys Just watched a Fullboost vid of the barra/zf powered commodore using a transbrake function via some sort of trans. controller... Is it possible to utilise a transbrake function via Pcmtec? After all, we must keep those transmission builders in business...

Puffwagon Posted October 28, 2021 Share Posted October 28, 2021 I reckon you could add the feature to the launch tune but you wouldn't want to accidentally hit the cruise button for too long while moving. For that reason you might want to use the flex functionality as an on/off switch. @Roland@pcmtec how many credits to add transbrake to the custom os?

Roland@pcmtec Posted October 28, 2021 Share Posted October 28, 2021 We do not have a ZF custom os. There are a few companies working on a hardware solution. All of them will require box out and either an external controller or modifications to the tcm. 1 Quote Link to comment Share on other sites More sharing options...
yoda598 Posted November 1, 2021 Share Posted November 1, 2021 Isn't a transbrake just activating 1st and reverse at the same time? Surely couldn't be too difficult to make some sort of momentary switch style system. Quote Link to comment Share on other sites More sharing options...

Surely couldn't be too difficult to make some sort of momentary switch style system. Yes technically the theory of what to do is not complex at all, the issue is implementing it. Eg tapping into the solenoids is quite difficult as you have to remove the TCM and resolder the pads with an intercept that will not fall apart when you go over a bump or get the box hot, then somehow get the wires back out of the box or via the TCM plug. You then need an interlock to make sure it can only be applied when stationary and in first gear. Doing all of this in a repeatable and cost effective manner is difficult which is why only one company to date has done this. https://www.facebook.com/XtremeFordTuning/posts/4306955426053984 1 Quote Link to comment Share on other sites More sharing options...
Milanski Posted February 9, 2022 Share Posted February 9, 2022 Ive done it in two boxes but only with the quick 6 and a transplanted 6r80 setup with owc 1 Quote Link to comment Share on other sites More sharing options...
rfh Posted April 5, 2022 Author Share Posted April 5, 2022 Hey Milanski, The quick6 controller any good? Quote Link to comment Share on other sites More sharing options...
Milanski Posted April 12, 2022 Share Posted April 12, 2022 late reply, my apology, just gettingm back into tuning my build. the only issue with the quick6 is that the torque limiting between pcm and quick6 is now removed hence if you are under throttle and it changes gear you get chirps!. other than that the quick 6 works, transbrake works. for tiptronic to work you need to do extra work, and sensors around the shifter or install paddle shifts. unless someone can convert the canbus signals from the microcontroller in the shifter to digital up/down signals... 1 Quote Link to comment Share on other sites More sharing options...

Nice unit! If you can be fucked there is a shift in progress output that you would wire to a relay that will switch in a resistor to the IAT circuit. Put a large timing value in that cell for a poor mans torque management. T-MAP Mk1 FG XR6T.pdf 2 Quote Link to comment Share on other sites More sharing options...
Milanski Posted April 13, 2022 Share Posted April 13, 2022 Very neat idea, bump the iat, will put it on the list of things to do. Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted April 14, 2022 Share Posted April 14, 2022 Another option is wire the torque output from the quick6 output to the flex input on the custom OS. You can then truncate spark/boost and whatever else you want with a variable blend curve without affecting the normal tune/overtemp protection. I spoke to someone (maybe this guy?) about 6 months ago about this and it would work a treat providing they don't want flex fuel installed as well. The flex input is measured every 10-20ms I believe so it will be quick enough to truncate torque. I'm fairly sure the shift in progress output is an analog output as well, so you can have variable torque reduction and technically make it work just like factory. Would take a bit to set up first go and get it right, but once its done you could copy paste to other cars. Unless you are running a seriously banger box, you need torque reduction on the 3-4 shift or you will kill it. 1 Quote Link to comment Share on other sites More sharing options...
Milanski Posted April 14, 2022 Share Posted April 14, 2022 Box will take 1000hp no problem. Thankfully rear tyres have little traction for now keeping the diff alive. What input is the flex fuel input, is it the rear o2 sensor input 0-1V? The quick6 has a shift in progress output that is pulled to 0v(ground) during a shift. Ive got an arduino set up to do the tiptronic function between the gear selector (oem ford shifter) and the quick6, therefore i can extend this to be anything i need back to the pcm. Just need to know where to wire it to please. Many thanks. Quote Link to comment Share on other sites More sharing options...
