I had been contemplating whether or not to map my car with a new tune file. There are very few vendors who supply tunes for the BMW i8 and they are expensive. However, a good friend of mine in the UK, Alex Myers, has been tuning this BMW i8. He tunes other vehicles but started tuning his BMW i8 many months ago for a better driving experience. He makes minor map changes and sees how the car responds, while monitoring the engine numbers via OBDII to make sure the tunes are safe. Alex continually tunes his BMW i8, and has recently uploaded 20 new map files to test his BMW i8 since the recording of this video. So, the file we used for my BMW i8 has been revised since this video.

Kassel Performance is a local Euro vehicle mechanic shop, performance parts installer, fabricator and Dyno tuner. Jim, the owner, asked if I'd bring the BMW i8 up because Kassel never had a BMW i8 on the Dyno before. Jim wanted to get stock numbers, test his tune and install Alex's map file and get dyno numbers on that as well.

I scheduled time to be there and my friends Soto and Evan from Thic Garage, and Geoff from Get Exhausted, both attended. Check out their Dyno videos:

I made a mistake upon arriving to Kassel. I wrongly assumed that the BMW i8 would produce Dyno numbers 15% below 357 HP and 420 ft-lbs of Torque factory supplied numbers, because I wrongly assumed those were numbers measured at the powerplant (at the crank), and there would be driveline loss. No! BMW uses at-the-wheel HP and Torque numbers as measured from the factory. Our initial dyno pulls were showing numbers close to that as stock. And, Jim from Kassel was very impressed. The car is very well tuned!

Kassel then tuned the BMW i8 based on their experience tuning other BMW 6 cylinder cars with valvetronic. They modified what they knew for the 3 cylinder in the BMW i8 and then made a few passes. The results are in the video.

Kassel then tuned the BMW i8 based on Alex Meyers map file he provided from the UK. During the test runs of Alex's tune, however, the BMW i8 had been heavily heat soaked and running low on battery. We actually ran completely out of battery and needed to "drive in Sport Mode" on the Dyno in order to get some battery charge, heat soaking the car even more. Both of these factors may have hurt Alex's performance numbers. To be fair, Kassel wants me to come visit again next month and do another Dyno pull, right off the road, stock and with Alex's tune in order to get a more fair comparison between Alex and stock.

This is likely the most comprehensive BMW i8 Dyno video on the Internet as of the time of this recording. There are other Dyno numbers out there and they may or may not compare to my numbers. I want this video to be a representation of the data we were able to obtain, and show video of what transpired during the entire process, to show exactly what I experienced in the process. It was a learning process for me, Kassel and Alex and we all learned something. My viewers also appreciate learning something as well. I hope this is helpful to understand just how good the BMW i8 is off the street and what power gains we can accomplish while tuning it.
