Good reputation from ratings, long history, good standing. What could go wrong? Depending on the product you buy, a lot. Thanks to a customer of his with a 10-19 S1000RR, we got to test the final product on the dyno.
RCK is BMW's "Race Calibration Kit". Floyd asks that you send in your cluster, immobilizer, and ECU. Usually this requires a bit of technical knowledge but okay, still on board with the process. Now to ship these parts off to his PO BOX in Texas. Expensive stuff to ship to a PO but alright.
While your bike stays at home and unable to use, Floyd gets to work installing RCK then ships all the parts back. We can confirm that Floyd did receive and ship the parts back. No swapping or anything. Now to see the results!
First the parts were installed, adaptions reset, bike was warmed up, put on the dyno, and was ran until it repeated a number. The number was 174whp. Now this isn't the important part. All dynos read different. The important part came when we reflashed the ECU to stock, reset adaptations, ran on the dyno until same temp as before until it repeated a number. Here's the sad part, the OEM stock flash gained 10whp more than Floyd's RCK flash that has his custom tuning. Almost $800 to lose 10whp...
Not only will RCK be enabled and therefore void any warranty but it will also have a mismatched mileage code, which is a HUGE red flag at BMW. It's basically suspected as theft and will have a permanent code for mismatched mileage between the cluster and the ECU. The VIN will also be mismatched because Floyd doesn't use legitimate RCK. It's a hack version he slams into the ECU. If BMW sees something like this they will definitely have some questions about how you used their proprietary tuning software without a license and why your VIN and mileage are mismatched.
It will cost $760 for the privilege of losing power. BTW Floyd is Lloyd as we posted before. He goes by MANY names. Buyer beware!
