I'm trying to understand the relationship of different variables to the ECM and was wondering if anybody who has already put the pieces together would be willing to make a logic flowchart to graphically show where and when the ECM draws data.

 

hahahahahahahahahehhehehhehehehahahhahahahehehehhahah


ok :-) in all seriousness, there is no logical flowchart, there are quite a few known reasons of why u change x it changes y and so forth but no book exists on this topic and u must play along on your own with your car a research things here and a diy-efi.org

try doing some searches here under the :final answer: which is a pretty informative series of articles by grumpy and check out trax's tuning articles....there is also a hack of several ecm's and their code at ecm guys site not sure of the address though..


before u ask questions here try and research what u already have found/seen, with what u can manage to find in yoru searches before u ask, cause the first thing u will get for a reply is do a search :-)

not being mean just trying to help a new guy out, i was there too once and there is still tons of stuff i dont know let alone can fathom lol

We have no unquestionable fact, dont know if that will ever happen lol.............there are a lot of answers out there and some superknowledgeable epoeple who will share with u provided u have done your homework first

later and good luck
