Stage 2 is excellent in warm weather, currently slips when very cold out. Waiting for a reply
My first tuning app and very smooth drive right after download. Can't wait to drive my 50 miles for transmission to adapt properly and see what this can really do
Software is flawless, so kudos to the software engineers. Stage 1 for my 2009 335i was poor in cold weather, though. Slipped A LOT and was up shifting into 5th by 35 or 40 mph which was faster than stock. Switched to Stage 2 and it's very good now, although I only have 25 miles on it and it's still adapting. Will change to 5 stars once I can really test it out. I have high hopes.
So easy to do an even worked with my jb4 plugged in! Can't fault it. Hopefully it was worth the £180!
Worked flawless on my X5M loving the gear changes and blips!
- Fixed a bug, where the App refuses to flash on Hardware upgrade
