I am sorry if this has been brought up before. I used the search feature and spent an hour or so looking and didn't find anything on this subject. But did read some good Lorena Bobbitt jokes.
I took my Sling to the dealer because my CBFL (catastrophic brake failure light) was coming on. The dealer takes my word on most of my issues and changed the pressure switches under a warranty claim. The service manager came out and told me the mechanic was having to bleed the brakes manually because of my tuned ECU. I told him it would be ok to hook up his computer to it as long as he didn't mess with any engine parameters. The mechanic who is pretty good with the slings came out and said that his computer could not communicate with the ECU.
When he brought it out, the brakes work the best I have ever had but the light on the dash stays on. The cruise control works like it should. He said he can't diagnose because of the lack of communication with the ECU.
I have spoke with @Dave@DDMWorks and he said this is the first he has heard anything about this problem because we don't usually let Polaris hook up to the Bob tuned units. I asked him to ask @MEFIburn next time they are talking.
