I'm sure others will comment on this, but there should be not correlation between flushing your brake (ABS) system fluid and any TTS tuning. Something doesn't make sense. Flushing the brakes (or clutch) should be a matter of draining the fluid, filling with new fluids and bleeding the system. I can't imaging why any Digital Technician services would be required for this service UNLESS there is some sort of reprogramming of the ABS logic.

The HD ABS recall bulletin requires the Dealer to use their Digital Technician during their brake fluid flush in order to activate the ABS solenoid (for an extended period of time) in order to do a complete, thorough flush.
I don't know if the Dealers Digital Technician will be unable to communicate with my bike, due to the custom TTS loaded map.
Thanks

It's not required to use Digital Technician or to activate ABS yourself to do a brake fluid flush. I was originally under the impression that it was required, as you are. I'd have to dig to find the info, but the bottom line is that you can do a fluid change, and as long as you don't introduce air into the system, you will be able to change the fluid 100%. I did this on front and back with no issue at all.

Couple questions
Question 1: just installed the RS468 cam in my Milwaukee 8. The can tune off the TTS program has the rpm limit set for 6200 rpm’s but the main lambda only goes to 5500. Does this mean it is only collecting data up to 5500 and how do you change it to 6200.
Question 2: Found the TTS for dummies article and it says to change the PE RPM setting to 10,000 rpm, the can map is set to 4300 where I assume it should stay when not tuning. Do I change it to 10,000 while tuning (flight recorder) or am I misunderstanding it?
Question 3: In the program, it recommends to leave the Spark Assist off till the AFR is stable. Is this accurate and can someone please post a AFR that is UNstable and one that IS stable.
Question 4: this is a two part question, The manual says to turn the ignition switch off and wait 15 seconds before starting. It states just the handlebar switch. Do I leave the power to the bike on then turn the kill switch back to run, then start it? And let’s say for the past 6 years I’ve been using TTS I’ve been turning the entire bike off and waiting 15 seconds before starting, would that be the reason I was not successful with tuning my last bike correctly? If not, what would the result be if I cut off all power to the bike instead off just the kill switch?
Thanks in advance, I know these may seem like some easy question for some of you or maybe not, but I would really appreciate the help. I had this tuner on my last bike and never got it tuned right. Trying to get it right this time. I love this program, just want to make sure I get it right this time.

I'm no authority but I'll mention a couple things...
Change to 10,000 for tuning, and back to original when done. I think this is mentioned at end of the Dummies guide.
I had the same experience. I know it was properly flashing the tune because each successive Flight Recorder run showed less and less changes to the tuning. I don't think it makes a difference either way, using the ignition switch or total power.

It means that is the last adjustment point and the ECM will continue to use that at any RPM higher than 5500

For Vtune it is best to set the PE Mode RPM to 10,000 to turn that mode off while tuning. Once done set it back to Original value
Question 3: In the program, it recommends to leave the Spark Assist off till the AFR is stable. Is this accurate and can someone please post a AFR that is UNstable and one that IS stable.
This is so you do not remove timing when the engine is too lean. Remember that Spark Assist can only remove timing and not add it back. The ECM doesn't know why the engine pinged just that it did and a overly Lean engine will ping and/or to much timing will make it ping. So its up to you to make sure it's not pinging due to being too Lean.
Question 4: this is a two part question, The manual says to turn the ignition switch off and wait 15 seconds before starting. It states just the handlebar switch.

You can use either one, the ECM just needs the power off for about 15 seconds to finish it's programming.
