I've noticed my egts are higher than I typically see on healthy logs.  I'm not tripping fuel dump, but I am seeing a small temp measurement at the actual egts (~950).  Egt at primary o2 is hitting 875 before 6500 rpm.  I'm logging egtmodelbeforecat for this.
Most logs I see top out egt at primary o2 around 775, so it seems like I may have an issue to address.

I put the stock M-box file back to see if it was something I had done, but the results are similar.  I see a little higher temp earlier in the rpm range on my stage1 file, but that seem to make sense since that's where I'm requesting more load etc...

The car isn't anything too exciting, k03s with an after-market catback.

Could this be a difference created by using me7logger, or should I be looking for a hardware issue?

Here are the stock logs:



and the stage 1 in progress logs:



I appreciate any input on this.  I can also post more logs from these sessions if that will be useful.

That was my thought as well.  It may be time to change the fuel pump.

No, I do not.  That would make this easier too.
While not comparable, here are the o2 voltages:

Stage 1:

You know that these temps are pure speculation on ECU's part and are strictly theoretical based on load of engine? If your tunes differ even so slightly on how much perceived load the ECU sees, the temps will differ too.

Different scaled MAF on both tunes will cause the load to differ and temps to be different as well.

Just so you know.

They don't. It's a calculated temp.

FWIW while I was testing KR based fueling, I pushed my car to the limit to test BTS and EGT (from sensors) component protection fueling and on my properly scaled MAF (within -+5% based on injectors flow and their KRKTE), the BTS computed temp was off by only 20 degrees C as once BTS reached 930C, that's when one of EGT sensors started registering a temp above 950. The other one followed within 10C afterwards but that's probably due to uneven fueling which is reality on all cars.

My KFLBTS map is irrelevant to his situation since my main fueling runs from KFLAMKRL map. KFLBTS is only used as true component protection mechanism with an activation threshold of 920C where it forces ECU into fixed rich fueling (but no as much as stock map wants to). If that's not enough, ATR kicks in at 950C which I also modified to not dump as much fuel as it normally wants (map DLATRNLN) as 10.6:1 is just too rich and causes misfires. I have it at 10.8:1.
