its very strange that ecu is not pulling the timing.octane level seems to stay at 100% at all times,even tho there is high knock level

 

that octane level is wrong it should be like 91 lol....

stupid gas we got here! and thats our major export!

 

The logged octane value refers to how much the ecu is interpolating between high and low octane maps. Nothing to do with the fuels AKI. With sustained high levels of knock, the ecu will start to access the low octane maps, which should be more conservative (built in failsafe).

 

i was talking about the octane level in reference to the 100 octane value in the logs.

the low octane and high octane maps are the same so interpolating is out of the question... even if it needed to interpolate between the high octane maps and low octane maps it should show higher values than the low octane map, right?

so how can the ECU decide on a timing higher than the high octane map???? lol

 

Octane flag does not reference octane of gasoline in the tank. A logged 100 value means the ecu is reading excluisively off the high octane maps. Yes, since you have high and low maps equal, it doesn't matter what your logged octane flag is.

Hopefully the guys that are currently helping you can figure it out, looks like your car was a bit fubar'd when you got it. This is the right place for help.

 

sorry i misread ur post i understand what ur saying.

yeah lets hope i can get ir fixed...i think my xml file (if thats what u call it) is incorrect and making the values i use to put into the maps through ECUflash wrong somehow??

i am not sure what to do cause my programming skills suck!

 

I think it's important to always have a different low octane map in case you get a bad tank of gas. Again, strange it's not changing to the low octane map.

 

Have you tried the race gas test to see if the knock goes away? Isn't japanese gasoline a completely different formula?

Have you checked for exhaust rattles or any other sounds that may be causing the knock sensor to give false readings?
