I recently had my FlashPro street tuned and want to visit my local dynojet for some before/after results. I would like to test the stock Si equivalent, one of the race calibrations & my tuned calibration.

1.)How much time after flashing the ECU with a different calibration should the car idle?

2.)Does it need to be driven at all for a specific amount of time or distance for everything to "settle"?

I would imagine a minute or 2 would be sufficient after flashing with 3 minutes between runs for reflashing and cooling down. Do you agree?

Idle does not matter when dynoing a vehicle. You do not have to wait between runs except to make sure that your temperatures are consistent.

the idle part was more of a question whether the ECU needed to relearn certain parameters after being reflashed. I guess it doesn't matter, which is good. Less time I have to spend waiting. Thanks.

how long does it take to return the ECU back to stock? I wanted to do some back to back video comparison of the stock tune vs my street tuned setup. When I went to load the stock map a warning came up about my battery voltage and recommended a battery charger.

Since I was at the "test track", I had no access to said battery charger. Is this a short process? Or does this take awhile?

Programming time is 90 seconds.

You DON"T want to risk losing battery voltage while programming your ECU though. I would wait until you have access to a charger.

yes mike this was my primary concern. I was literally in the middle of nowhere. I wasn't about to risk something catastrophic happening to my ECU. This was simply for video documenting stock vs tuned calibrations.

Thanks Hondata.

I did notice that one time my laptop said something about battery voltage being low when I flashed my car. Any background here would be helpful.

I guess what I'm asking is what causes this? Should you NOT flash you're car if FP Manager gives you that warning? How do you remediate it?

It is not a good idea to flash the ECU with a low battery voltage. If you get the warning, then the cause often is leaving the ignition on before programming with the daytime running lights on.
