Thanks, Payam. But FYI, water freezes at 32F LOL. We need to see how the thing works when there’s ice and snow everywhere!

But keeping the stock heat exchanger helps with fluid heat up when its cold outside. So one could ADD a Tstat and the BMS cooler as I suggested above may be an even better solution.

This is a great idea. Id like to be able to get the right fittings as well as I mentioned above. A little more involved, but better functioning for guys like us in the north with cold winters.

I like the idea of leaving in the original heat exchanger and sending the oil output to a Tstat, and then either flow back to the heat exchanger if <160F for quicker warming up, or to the BMS heat...

It’s likely too lean. I had this code for a while ago and made a thread about it here or on one of the other forums. Ended up increasing my scalars to 1.05 from 1.00 to solve the code.

Rough idle can also be cleaned up with using dielectric grease on the insulators of the spark plugs. Must do this anyway if using upgraded coils like PR or BL.

Have you tried logging during idle and see what shows up? For example, are the AFRs between banks 1 and 2 very different ? If so, could be an O2 Sensor.

I’ve been using xHP Stage 3 ever since it became available. Prior to that Alpina B3 for 5+ years ever since it became available. Stage 3 xHP absolutely superior. Love it!
