Maybe, the Fuel Open Loop variable adjusts automatically over time. If trims get too high, and there is room to adapt, it will move up. Opposite if trims bottom out. It can vary based on your car,...

Your log was very short, but from the snipped fuel pressures looked OK. You probably just need to adjust or let it adapt more. Try map 1.

Did you upgrade over a large gap in firmware versions? If so, some of the settings/defaults may have changed. Common problem in that case. If you reset the settings to the current defaults per the...

Switching because of lean condition on both banks. Fuel trims maxed out. Raising the fuel open loop a bit manually (maybe try 85 or 90) may help. Seemed it learned up a bit already automatically...

The virtual sensor is a total guesstimate based on the O2 readings, and has to be adjusted depending on the DME/flash. You have an IS model so it differs a bit from a base N54 tune, so maybe you need...

BMS is based out of California so unfortunately anything emissions related is restricted on the forum and in the software.

Those temps are reminiscent of a car with no oil cooler at all. Almost sounds like the loop to the oil cooler is blocked. Is the rad actually getting hotter when you get above the t-stat set point?...

If your JB4 had a newer firmware (5.15+) it should automatically switch to Map 0 when something is active on the ODBII port. In the past this did not happen and there could be conflicts on the CAN...

Not a PI expert, but is LPFP reported the same with that kind of setup? Because it got right down to 50 right before your trims/AFR went out of whack each time. I'd be surprised if you had a LPFP...

You might have to manually lower FF since things are flowing more freely and less PWM may be required (it will adjust automatically over time too). Similarly, with inlets you sometimes need to...

Any of these USB-serial or USB-FTDI cables can be finicky with different versions of Windows and different laptops. Got another one you can borrow maybe?

Make a note of the default settings, change it back to default if this doesn't work.

Try setting latency to 1ms and timeouts to 0.

What OS? Sometimes try different USB ports. Try a 2.0 one if...

Ignition in fully-on state?

Also, check the COM port settings, in the advanced settings you might have to adjust the latency and timeout values (common for CAN cables).

Which model Endless pads did you get? A lot of them are pretty aggressive street+track pads. They might not like cold temperatures, and probably need a bedding-in process.

I'm more from the BMW side of the house, so maybe I am reading it wrong, but I do see you are maxing fuel trims which is leading to a lean condition. You had a safety stored for that, but it wasn't...

My last report was with 81k miles (13.5k on the oil), and iron was 61, copper was 14, aluminum was 7. They indicated that iron should be around 4.3 per 1000 miles driven on the oil.

Makes more of a difference for pump gas / pump flash users, where timings are lower by default. Probably less of an benefit for E85 users. Eventually at high boost levels you'll likely need the...
