Question Cobb Accessport V3 time required to flash the map question

Hello everyone,

Flashing maps via Cobb takes around 10 to 15 minutes in my case, is that time normal?

I have heard that changing maps via Cobb should take no more than 10-20 seconds, that's why I am concerned.

Cheers

From my experience, it depends on the amount of parameter variation from map to map.

For instance, when I went from stock to Stage 2+ it took about 10 minutes or so I guess. Also, when I went from Stage 2+ to my protune from PTF, it took that long as well.

But when I go from revision to revision when refining my tune with PTF and there are only minor tweaks, it takes less than a minute.

The initial flash takes about 10-15 minutes. Subsequent flashes should only take a few minutes or less but as mentioned above it really depends on the amount that is changed from Map to Map.

The initial flash will be lengthy and varies 10-20 mins. Thereafter switching from map to map should be rather quick

When I had my protune it took 1 min or so to switch. When I first started to flash my car it took 10 mins the most from what I recall.
