Hi,
Can you Please find these values for AZ1G400W i'd really appreciate it!
Maybe these corrections could be the reason it's so hard to dial in your closed loop MAF scale and EL comp's, what do you think?
Do these corrections remain active in open loop?
Regards
Easty

I was able to define this table in my rom thanks to your instructions.
For Cal ID AE5IA10V the table is 3447c (2011 USDM STi).
Tomorrow I'm going to zero out this table and remove the rear o2 sensor completely to see if the correction goes away. I already idle/cruise slightly rich which I assume is due to being catless. The ECU has always targeted 14.59 - 14.6 after I went catless. It would be awesome to have this correction gone and to be able to keep my wideband installed permanently.
Thanks for your work on this.

Thanks Very Much!! Tested it out today and it all works!
I noticed before i zeroed them out that the last correction was held into open loop this could explain why every time i check my OL Maf Scale its approx. +-2.5%.
After zeroing out the limits AFR seems to be more stable now. I'm not sure if it's my imagination or not but my idle seems smother now to.
It will be interesting to see if this affects economy though it possible won’t as these corrections seem to oscillate about zero.
Cheers!

I was wondering if anyone can help me out?
I can't use IDA to save my life so it's probably best if I don't attempt to change anything.
Throttlehappy is helping me out with my tuning, would anyone be able to help me out with changing my rom to zero the rear 02 limits?
