I have always tried to use the search and have lots of luck, but just wanting to make sure and seeing if anyone lately has had an issue.

While out testing a new fuel map the engine light came on once again. With my ecmdroid it showed the ets 14 was high again but I noticed my temp was showing -10c. So I ran her back home and hooked up ECMspy to make sure and it was showing -10c. My first thought was that it was the wideband O2 sensor I installed. Put in the NBO2 and it was back to normal. But as I started the bike back up to do a TPS the temp gauge on ECMspy dropped back down to -20c. I let it cool down, pulled the tank and did a wiggle test-nothing. Could I have a bad ET sensor? I pulled the plugs and both were black. While I'm at it are the NGK DCPR7E's better or the DCPR8E's.

The bike is a '01 X1 with race header and D&D muffler, Crane cams roller rockers. Race EEPROM from Purpony's website.

Engine light for temp has always come on ever since I've owned it (2yrs).

TIA

That sounds like the culprit. You are saying minus 20 degrees, right?
Was your IAT reading around 90 degrees F?

Minus 20 deg c. The cold start enrichment was at 176, that's why the plugs were black. Inlet air temp was 32 deg c, close to 90 f.
