Re: P04 Disassembly
There’s still a lot more. That doesn’t even have the injectors or spark stuff. I’ve never looked at the spark output or fuel outputs in a pcm so I don’t know what it looks like to find them. It’s going to slap me in the face when I do find them. I already know where the outputs are I just need to backtrack them until I find the clues… and map the spark and injector stuff from tiny tuner since I haven’t done that yet.antus wrote:Nice find
Re: P04 Disassembly
Tracing spark and fuel times is not possible due to another processor that is responsible.
It is called TPU and not much is known for it.
Main cpu only stored some scalars and tpu process them at later stage.
For spark you are looking at final advance/retard converted to timebased scalar and spark dwell time.
For injectors, EOIT, time for injector opening and some low pulse offsets as a different scalar.

Re: P04 Disassembly
Yeah I don’t imagine it will take too long once I use the database.
I have mapped a significant amount so as I go it’s getting easier with the web of info I’ve already put together.

Edit: Too complex. Should be simpler.

Re: P04 Disassembly
edit: I think I found one that makes slightly more sense.
