Was posted in another thread but more relevant here, does anyone know the RAM address for the second 02 sensor on an A01G rom?

I noticed the 'load' value for B01C Roms is in g/s whereas the ECU tables are in g/rev. I've made a script to produce a new load value based on MAF and RPM, but am curious if the ECU has an address for load in g/rev.

All load is g/rev. It's probably just a type error.

I've had a quick look at the OBD call table disassembly but have not tested:
Can you try FFF8D274 and FFF8D278 and report back?

Will try these later today and report back:

paramname = AFR2
paramid = 0xFFF8D274
isfloat = 1
scalingrpn = x,14.7,*

paramname = AFR3
paramid = 0xFFF8D278
isfloat = 1
scalingrpn = x,14.7,*

Off OBD Mode 01, PID 15, I'd expect D274 to be sensor volts reading between 0-1V (scaling rpn=x); 1V is rich, 0V is lean. Expect D278 to be AF3 trim (scalingrpn=x).

From the logs it looks to be similar in magnitude and value as the MAF logging, so I assumed the issue was related to that.
I'd much rather have a log of load than be calculating it. I guess doing the math with someone else's log could help me determine if my math is right.

Where would I start looking to fix this?

So you haven't got a parameter for load? Calculating it isn't ideal due to the compensations that are made, there will be slight variances.

What file are you using for logging? Plenty of info on here to check the correct load parameter.

I got addresses from the 'b01c' addresses file. I can't remember which of the other files I started with, but there were a few things which needed to come over from the addresses file.

Did some logs driving to work today using your values:

paramname = AFR2
paramid = 0xFFF8D274
isfloat = 1
scalingrpn = x

paramname = AFR3
paramid = 0xFFF8D278
isfloat = 1
scalingrpn = x

Here's my current log config: http://pastebin.com/tNTbKqzK

paramname = Load
paramid = 0xFFF8DB84
isfloat = 1

assuming that ram address is correct for your rom type your reading the "load" from the ECU it calculated by the ECU and not scaled by the tactrix ie no scaling is applied to value read from ECU.

The values you should range from almost 0 at idle to about 1.3 full throttle under load

None of the configs from the OP scale load, so I'm guessing the address isn't right, or something similar.

try @phrosty he is on b01c or d rom sure he has a working logcfg.txt for that rom. strange load does not work as most guys would want that for maf scaling.
