Title: Maf table on M2.10 Post by: curamrdan on February 03, 2015, 05:48:47 AM Hi, can you help me with proper visualising of MAF table on older M2.10.x (in XDF tunerpro) ?
Its not classic 256x1 or 512x1 table, is something like 16x16 on older BMW 3.1/3.3 motronics, but not at all. Its tested by eprom emulator, that is going up thought the cca B100 adress up to cca B200 with upping airflow, so it is maf table (http://s13.postimg.org/b154uomp3/unknown_Maftable.jpg) (http://postimage.org/) upload image (http://postimage.org/) Title: Re: Maf table on M2.10 Post by: curamrdan on February 03, 2015, 03:42:03 PM Make some search, its the same as on Volvo M4.4 where some info is available.
"The MAF table is split, as it uses 16 bit values, but M4.4 is an 8-bit system.. so there's basically two groups of 256 values -- one group for the high byte, another for the low byte." On picture is low byte table, high byte is just before it. Hope it helps for someone ;) |
