Q45 8bit gear fuel maps causing comms issue...strange..
Posted: Mon Jan 18, 2021 8:45 am
Hi All,
My first post so go easy on me.
I have finally worked out what has been causing an upload/comms issue for pretty much the whole time I've been setup. This issue rears it's head whenever I upload (to ECU) the gear fuel & gear knock fuel maps...after many of hours of resoldering and head-scratching!!
I have been trying to copy 'reasonable' fuel maps into these tables in-case these get accessed. I don't believe they would have, as the engine would not run for long (Check images).
Anyway, whenever I try and upload to the ECU either of these 2 maps from any reasonable tables, I instantly get a comms fault that will not clear unless I power down the ecu for a good few seconds (and sometimes restart nistune). I am guessing something in the addressing for these tables is incorrect.
As a work-around I have just uploaded all but these 2 tables whenever I make changes. They are not pretty, but guessing they are not accessed anyway, so will leave as is.
Keen to hear if anyone else has had this issue.
Cheers,
Lincoln.
