Well done on finding the source of the problem!

Since I'm running a Jap spec, there is no rear o2, so I guess I'll have to run the patch to suppress the CEL.

Once again thank you to SeanV for your efforts, trying this out tomorrow morning!

Lol, no.... Acumas,MrFred and Logic deserve all the credit.

I just happen to stumble on the patch which was there are along.

Good luck, hopefully it works for you too.

Yeah I'm on 96530706 from 96260009 which uses injector scaling of 542.
What I did was to adjust my MAF scaling in the 19 - 75Hz range down around 4%.

You could also slightly reduce the injector latency, as the latency values that go with the 542 scaling are higher than the ones that come with the 513 scaling.

This is what I use as a latency for 542 scale
3.312*1.68*1.032*0.72*0.48*0.36*0.24

Edit: Since I don't have to worrying about emissions/passing inspection, I just had to add the lines to my XML file from the link above to surpress the P0141 rear O2 Heater code.
Nice and simple.

I am on V5.10 and have the O2 sim active, this disabled P0136 but still got a P0141, can I add the lines from the link to my V5.10 xml to disable P0141 without any problems?
