Will Increasing Fuel Pressure Increase O2 Readings

[Ttype6]

I understand what is going on here. He and I have the same tt chip, and he was maxed on his WOT BLM lock (and I think it shows what it is locked at on the SM when going WOT). I was asking him if he now his his WOT BLM down to the default chip settings instead of maxing it out.

My fuel pump passed the test, but I am maxed out on the chip, and have added a little bit of base FP (this was the reason for this thread). I am seeing the WOT O2's that are in the .780-.820 mv range.

I remember your post. Are your BL numbers near 128 at Idle and cruise?

Last I looked (havent driven the car in a week) I was cruising at 125 ish and 128 idle. I will re-check my FP again, but my O2's are good.

Hello,

Yes. My O2 numbers are much better with the chip brought back to 128.

I have brought the chip parameters back to 128 and have O2's around 780-820.

Going forward, I will be working on "tweaking" the tune.

Thanks
Matt
