Have you updated your OFT lately? There was a bug that we fixed a couple weeks ago that made adv multiplier go to 0 if you cycled ignition while in the logging screen.

Yeah, updated before using it. Maybe I'll do a clear everything start over?

No reason to clear everything. Just try it again and see if it behaves the same way. To be honest I haven't personally seen any cars that have old 700C native roms. So perhaps the they use a different channel ID for advance multiplier. I doubt it but it's certainly possible. If so, I'll have to get my hands on a 700C car and sort it out. But this is the first time I'm hearing about it.

Hi Shiv!
Seems that international ROMs are also running rich AFR on WOT as well and it looks like a kinda bug. Can you probably arrange some common fix for G-series roms rich WOT AFR as well as Adv. Multiplier logging?
Or should it probably be some reading/logging error in rich WOT AFR with international roms?
Mine is running 11.25 AFR on WOT.

Not sure I would call it a bug, perhaps our fuel is miles better than the Cali piss?

I would like to see more logs for G series ROMs before making any changes to the OTS maps. The reason I'm skeptical that this is a universal issue is that the stock G series ROMs share most of the same fuel mapping values as stock USDM ROMs. Which would suggest the stock tune runs rich as well. I have yet to see evidence of this but I'm sure I'll get more feedback from more users over time.

God knows! I use LUKOIL premium fuel. I know that LUKOIL stations are available in the USA, but located mostly on the East Coast, in New Jersey, and i am not sure that they are selling exactly the same gas in US as they do here.
We may have different standards of the fuel here and there...

finally able to do a decent WOT on 3rd gear from 2k rpm..

they are different. i think the 98 RON is more like 94 AKI, also i don't think you have 10% alcohol in it, plus various additives or their amount is different.
besides, according to your forums you may have variations from station to station, some people in Moscow swear the Lukoil gas station near White House is the best, lol.
i would just try a different brand, maybe BP, or trying out 95. log it, see how AFR changes.

Here's a brief 3rd gear pull (fuel type should be 98 RON not 98 oct): http://www.datazap.me/u/akyp/oft-sta...-2-7-8-9-10-11

Question: Does higher octane fuel cause AFR become rich?

I'll do more logs if it is of any help to you. Damn rain during weekend...

I'll also add I don't mind running a bit rich as a safety margin. Better safe than sorry.

I've tried it three times, advance multiplier never changes from 0. Also, upon start up KC learn drops to zero within seconds, but I'm guessing the two may be related.

Also, when I tried to download the second log last night, the manager said the tablet had to be initiated and I had to calibrate again. This happened twice within minutes. However, the tablet still had the original ROM stored. Not sure if this has anything to do with the advance multiplier or not.

Will try. Despite the fact that it is very difficult to buy worse fuel for the purpose.
And no - of course we dont have any ethanol in our fuel.
And one more thing - when i just took my new car from the dealer, i bought some 95 RON fuel from the nearest LUKOIL station and immediately got CEL thrown.
There were P0017/0019 codes.
After this case i use only 98RON and not getting any CEL since that time.
So 95RON is a kind scary thing for me.

Basically I'm just suggesting to try different gas blends while logging and reviewing those logs as it seems there is nothing else really different. Also, get in touch with shiv rather than just posting here, I'm sure he'll be curious to find out what's going on as well.

Holy revs, Batman! It's looks like you stayed on the rev limit long enough to see an ignition cut.

The lines are thick and condensed enough that it is hard to extrapolate exact numbers, but it looks like you might be a bit rich, as well.
