NOW TUNING 22-23 CHALLENGER
Lately, there has been a lot of talk about tuning your Indian motorcycle, whether it be PVCX flashing or PCV to piggyback on top. People are concerned about warranty issues and whether a dealer or manufacturer can tell if either was installed causing the warranty claim. Well, Polaris can tell if and how many times the motorcycle has been flashed, so some dealers prefer to use a PCV that they can remove if necessary and not leave a trail. But that’s not entirely true. The manufacturer can tell that the duty cycle of the injectors had been changed from the PCV if that’s what they are looking for. Injectors stay open for a given time buy an electrical pulse. So the ECU will record this.
Either way, it’s about the Manufacturer looking for an excuse to not cover warranty. It is up to the manufacturer to prove that the failer was due to the tune. ( which it never is, remember we can read code too ).
Now the image I ‘ve attached below is a screenshot of Indians Target AFR’s, which is appalling. They just did a lean 14.7 in a large area for cruising and then just dump to a 12.7 rich mixture for everything else. Now the problem with this is that if you make any changes to the bike such as intake or exhaust or even cams, this map is going to go even leaner and there is no room for that.
So the manufacturer can’t tell you not to Flash the ECU because engine damage will occur if you don’t. Harley have been flashing ECU’s for years and know tuning is critical.
