I guess thats why Al says you always need to run preimum fuel with his flashes.
Personally I wouldn't want to modify my low octain map for the simple reason if I get a bad tank of gas I would like the ECU to have the room to compensate.

Very Very True, I would never flaten both maps out, if anything i would detune the low octane map for an increased level of safety.
Yes I have a fuel Pump.

It worked out well either way that this is the case as I used to worry what my Xede was doing when/if the ECU floated maps. Guess that concern was for nothing
Do you know what the conditions/triggers are and the values needed to float maps?

Closer to "0" the ECU reads more of the High Octane Fuel and Ignition Maps. If this value is in the middle between 0 and 255, the ECU uses a little of both maps, something like fazing over. If it's near the "Ocane Value 255" It's all Low Octane Fuel and Ignition maps.

I understand that doing that gives you a nice stable tune to work from if your using a XEDE or another system that needs it..

I am looking at the JM9693 map and there definitly is a difference between the maps.

Exactly. I noticed the samething with that ROM. My TT tune was varied as well.

Colby said that these were stock maps. I'll take another look once I get home this evening, but I believe both of these has lo/hi octane maps there matched. I'll post screen shots later.

This one wouldn't load any maps. I didn't mess with it to try to figure out what was wrong.
