Default Realtime vs. Reflash

Searched on Cobb's website and on this forum but couldn't find an answer.

What are the differences between the two?

Does the realtime one only last until you turn the car off? Do you have to connect the green test connectors for both? Etc.

real times does not require test connectors. real time maps have "most" of the data you'd be changing, but not all. they last until you RESET THE BATTERY, not just car on/off.

can we quantify/qualify "most of the data"?

haha ok "most of the data" is this:


wgdc hi / low
primary fuel / ignition
dynamic advance
turbo dynamics prop / integ
avcs
boost limits / targets
rev limits
maf curve
injector latency / scale
closed loop tps table / base pw table

awesome, thanks. just wanted to make sure you actually could change maps quickly at a stoplight with the car off if you wanted to without any real repercussion.

yeah, you could do that. it takes about a half a minute, depending on how many things actually change. you could leave it plugged in to obd port, then just go for it.

You can change the map when your driving down the road too.

Hey guys, question on the same subject...I'm pretty new to the Accessport, far now I find it wonderfull!

Let's say that my base Flashed map is Stage 1 93 and I'm running on 94 fuel. Here in Qc we doesn't have 93, premium fuel is usually 91 except at Petro-Canada where you can find 94, but not everywhere...so at certain point I can't find any 94 and I've fuel it with 91. In that situation, does a RealTime to Stage 1 91 is enough or it's better to do a Reflash on that map?

Thanks,

The "base" map is your entire tune. That is, if you were to open a map in our AccessTUNER software, the "base" map would account for any change you made (relative to stock) to any of the hundreds of tables available in the latest software.

The real-time "map" contains the changes to a smaller sub-set of tables that we've designated as real-time. When you marry the AccessPORT, it changes the factory ECU to support this functionality which would not exist otherwise. Real-time tables consist of about 10 or so tables which are some of the most commonly tuned tables for boost, fuel, timing and AVCS (depending on ECU). The real-time map will "override" the corresponding tables in the base map with the 10 or so real-time tables.

So, your base map should always be the map that is designed for the mods you have. The real-time map can be a map where the changes necessary can be accounted for by those 10 or so major tables. Examples would be different octane gas, high vs. low boost map, economy, valet, anti-theft, etc.

The advantage of changing the real-time map relative to a base map is that it is faster and can be done with the engine running. For the sub-001 and sub-002 cars, it also does not require connecting the test mode connnectors. But, a real-time map is not permanent in that if you disconnect the car's battery or reflash a base map, the current real-time map will default to the values in the base map (until you load another real-time map).
