Normal 91 oct pump gas is around 260-270 ish
btw, send me a PM, I'm interested in some things.
The timing seems to be good (comparing with PCMScan) and since I'm running a Dominator 2.0 my abs load is pegged at 255 from 4000 RPM all the way to redline so I can't confirm those numbers 
yw.
The knock count/retard one I posted is definitely spot on. I tested it on another X today and I was able to identify the dealer filled the poor car with 85 or 87 before it left the lot... 13 counts stock! Pretty ridiculous. Even after reflashing the car was still dumping fuel and pulling timing due to the detected knock.

I wonder how PCMScan is determining load...
I wonder if this value is actually knock sum instead of the listed knock retard. If this were knock retard, the actual timing would've taken a huge dive (13 degrees worth) and I've never seen such thing happening on an EvoX yet. If it were sum, then that would've been around 4 degrees of timing which sounds about right. Also, you mentioned that you always see 1 or 2 degrees but maybe this is sum

Don't you love the logging speed of PCMScan
The load values don't seem to exceed 240 on a stock USDM Evo X. I wonder if someone can test the CAN 20-1 to see if it's accurate. Other than it being capped at 255, I'm thinking it shows too high of a value.

Have you found a way to log Injector Pulse Width? I looked but could not find much. If I can log IPW, then I can write a PID to log IDC.
The highest a stock X has logged in 4th gear is 231. An Evo X with a drop-in hits a hair less load and an Evo X with an intake hits a lot less load.
The more I use PCMScan the more I like. I only miss Konck Sum and IDC.

I've found these to be working. Injector duty cycle is new and is a product of RPM and injector pulse width.
I'm still working on load and boost. I see the MAP value but it seems to be capped at 125 kPa or ~18 PSI. Load is still a mystery to me. I may try combining 20-1 and 20-2 later. Maybe 20-3 has something to do with it.

Thanks WarmAndSCSI for your contributions! They seem to work for me - now all we need is boost and load
BTW, I'm also at high elevation and I think my car at 5000 feet is hitting lower load cells than typical stock evo x's. I believe load is really topping out at between 180-200 at 3500-4500 rpm's and dropping from there (compared to a stock X at sea level that tops out between 200-220 load). Hitting lower load would explain the slightly higher timing advance values we're seeing.
Also, I tried both 11-1 and 11-3 for knock sum and both stay at zero in all my logs. I guess the only way to truly find out if it's working is to advance timing until it registers knock?
I'd appreciate anything you can share on boost or load logging!
