Sorry for newb-ness of this post. I just picked up my '10 GSR last night from Jason @ southcoast <:

I would appreciate if someone could help me bang out some of these questions.

I was wondering if anyone could direct me to some general electrical specs on the engine.
-Crank patterns (36-1, 60-2, 12+1 ??)
-Cam patterns
-Cranks to Cam Intake offsets
-cam intake to exhaust offset, and phasing margin ( by looking at the ecu, it looks to have some sort of cam phase control.
-Standard resistance of the injector (10ohm, 13.6mH production injectors??)
-Current demand of the Electronic throttle motor?
-CAN bus messages on the CAN-A bus from the ECU to the other devices in the car
-some extra info on the oxygen sensor, and control range for the heater ( we usually run our NTK's ~ 800F)


I work for Honda HPD up in Santa Clarita, just finished the build and application of our own ECU that we use for our motorsports endeavors. We have the capability to at least interface with engine loom, and run software app levels same as what we use in our prototype cars.

Please be friendly, I am new to the EVO scene but very excited to start coming up with some devices.

I was wanting to make a logger as well that would open files up in McLaren Electronic Systems Atlas system. If any of you are in any sort of pro racing / sports car level, you'll know how useable and powerful it is.

You need the factory manual on CD. Bunch-O-pdfs with everything you are looking for. I have it. I can burn you a copy or maybe put some of it where you could downoad the important parts. I am out of the shop till Monday night. The rest of the crew is there though (well I hope so anyways :-P) Like... they said they would be working hard and stuff :-/

Got my first scan of the can bus on pins 90/91 on the evo x ecu. The bus is 500K, and these are most of the messages that I saw, and s

This was done while the car was ign on, yet stationary, not running.
It is going to take a while to decode where each message is coming from, and associated it a measurement. I know that the acd is on this bus, along with the TPMS system. I am not shure if the meter is on there two. This may be a faster means on measurement for future tools rather than using mode 23.

Got the docs for crank and cam patterns, will be working on porting that to my own ecu
