How do you get this update Gp184? Is it directed form H&S?
yes. it is a trial just for the people with the Mini-Maxx. it is a manual download.
here is the post by them from the DF:
Mini maxx update to combat turbo hiss at idle
New tuning calibrations for a Mini Maxx on an LML to address "hiss". Feel free to load this calibration to your LML, and report your findings.
We are attempting to create a calibration file that will address the loud "hiss" at an idle that emissions removed customers are hearing. This can be heard more noticeably on trucks that don't run a muffler.
There are literally hundreds of changes made to this file, and we hope to cover most all scenarios that the truck might come across. You WILL still hear a slight hiss at start up as the turbo cycles fully open to fully closed for a diagnostics check, after this the "hiss" should subside. Factory programming keeps the vane control duty cycle at around 85-95% during an idle state. We are now attempting to command the turbo to remain at 50-65% duty cycle. All other driving and operating range turbo control should be unaffected by these tuning changes. Our shop LML performs just as we command, staying at around 60% vane position under any idle state.
** This is a manual update, and you will need to have a few basic computer skills to get it to work. Our auto-update program will NOT get you this set of files until testing is complete.
** This is ONLY for the MINI MAXX products. This will not work if you have an XRT Pro or Black Maxx. Those products will be supported once testing is complete.
1. Download the software at the link below. Save it to your computer somewhere.
2. Extract the saved folder.
3. Open the extracted folder, so that you can see multiple individual files.
4. Copy and paste ALL the files onto your SD card, replacing any instances that already exist.
5. Update firmware (Menu > Update Firmware)
6. Install the tuning software (Menu > Install download > H&S tuning.... etc)
If done correctly, your version number in show settings should now be at T.V.6.6.38.

Please drive the truck for multiple drive cycles, then report back. We want to know how it reacts after a cold soak (longer than 8 hours engine off), as well as after a long drive at full operating temperature. Please keep the information you provide as accurate as possible, so that we can work towards a solution (if need be) as efficiently as possible. Thanks!
