i did not pull those myself. i think those came from eec analyzer site. i will do some more digging.

Well based on this I think we can just change some hard coded limits here to allow for more than 162hz. It is literally hard coded to not read anything beyond 162hz (WOT in death valley I guess) This is the A1C MAP Subroutine. I tabbed out the if statements and converted the words to decimal and divided by 256 to get the values. C code only down below. We should be able to determine what R56 and R5c represent and set appropriate values for boost. Seems easy enough unless this is just the tip of the iceberg.

Thinking about removing all of the nested if statements and adding functions to lookup values for r56 and r5c. It should look something like this:
Thoughts?

try it out and see
unfortunately I won't be of any help any time soon I'm backed up pretty good

No worries, I've started writing the code maybe one of you other guys can help me figure out how the argument address location is calculated. It made sense to me in the past, but I can seem to figure out how from address 4b51 in the example below using 0218 the computer addresses the function at a618.
Is it a reference address + 0218?
Code: Select all
4b4e: ef,b8,fb call 4709 UUWFuncLU_4709 (
4b51: 18,02 #arg 1 Func_a618,
4b53: 38,00 #arg 2 38 );Re: Bench Testing MAP Sensor - Boost

An argument is based on the calling routine. You have to go to the 4709 routine to see whats its doing to get that.
