i have decided to unertake expanding the 749 code as a public service. not only coud i use it but lots of others could as well. my basic plan is simply to expand the fuel and spark tables.this is sort of the rough draft i have at the moment for that goal.

tables 1 1 fuel & 1spark 0-110kpa
tables 2 1fuel & 1 spark 120-220kpa
tables 3 1fuel & 1 spark 230kpa-340kpa
tables 4 1 fuel& 1 spark 350kpa-460kpa.

i know this is complete overkill but hacking the existing code just sucks the resolution right out of it. also planning on having to change the scaller and table pointers, look up routines of course. The whole thing hinges on being able to use the extra 16k of space that the quad4 code uses up. at this time it would be nice to swap in the dwell control and make it bit selectable to run dis once i can find someone who knows how that code works.id like to start simply with the fueling maps. the timming dwell code for dis would be a nice goody but isnt the most nessacary thing. but it seems like a workable project from my standpoint.

i taking tips pointers and even suggestions on where to get info hacks and other such goodies for the project. its a long road and ill take all the help i can get maybe even starting a thread here to keep in the stickys on the code progress would be great latter on once there is a templete for how to accomplish this.

so i ask coder gods where do i start. ?i have the basic frame work but i lack the codding knowledge can you help me attian that ?

 

ok back TTT. im not asking to be spoon fed how to do it. i just want to know where i can find out about assmbler coding. as in actually writing code and op codes. any good books. ?? i know somebody out there knows i just need some help getting going with the info. i dont want anybody to do this for me. but i would like a helping hand in where to collect info.

 

I just can't help myself... sorry.. but maybe reading the sticky above regarding source code may help. from there its a long boring read of 68hc11 series motorola data.

 

sorry i didnt realie that the post above had the the info. i thought it was a typical grumpy lecture on why to figure out the source code.
