sounds interesting.. basically im wanting to know how to find/identify maps in ME7.1.1, i dont trust commercial tunes after seeing the complete dung that was put out there for the E30's (which is why i ended up getting into tuning in the first place lol). and i know many tuners and commercial brands basically bump values in fuel/ignition maps and then call it a performance tune. so ideally id like to get to the stage of being able to tweak ignition and fuel maps in my pheaton and get a little more poke from the engine, maybe do a little dyno tuning but no major engine mods, certainly nothing more than intake/partial exhaust as its a daily driver.
in the old motronic 1.0-1.7 and maybe a bit newer still there are axis descriptors which tell me what the axes of maps are, like RPM vs load, IAT vs coolant temp, etc, etc, etc. also the axis data follows each descriptor and subtracts from each prevous byte of the axis data.
the only maps i have found in a ME7.1.1 VR3.2 file from a phaeton like mine are what WinOLS automatically picks up which isnt much. i notice there is no axis descriptor before the map data and the axis data does not calculate the same way. is there a table/index of map addresses like there is in the old stuff? basically a string of hex values that tells you where the various maps start.
cant make heads or tails of the ME7..1.1 file lol
@ rabbitchaser, if your already tuning and just want to scale maps for larger injectors you could fudge fuelling values in idle/cranking fuel maps till it starts then read your AFR in idle and adjust until its where you want it then apply the same difference to all other necessary fuel maps. another way would be scale coolant temp sensor or airflow map values.. or injector constants map. depends what maps you got/know of. i find (on the BMW ECU's i tinker with anyway) that scaling the fuelling values in all fuel maps (cranking, idle, part throttle and full throttle) gave the most consistent results. messing with injector constants only seemed to work up to a point and tweaking coolant/airfolw maps has fuelling spot on one minute then away off later. i had my E30 running perfectly on 30lb/hr injectors with a basically stock engine after tweaking fuel maps (stock injectors are about 15lb/hr FWIW). i can definately go bigger if needs be once im boosting the E30. spark blowout will probably be my limiting factor tuning the old stock ECU, kind of limits me to the stock distributor ignition system and theres only so much i can do with that.
