My exhaust temp sensor has been broken for a long time. I've rode without it for quite some time. I went for my first ride out with my Riva Ecu and it threw this code, which I found to be the code for the broken temp sensor. Why would my stock ecu not throw the code, but the Riva did? What is the issue with riding without this sensor? As I said, it hasnt been working for a long time, I just forgot about it because there was never an alarm up.
I will buy a sensor and replace it obviously, but is it okay to ride for the weekend?
Also, I think i remember BD or Sno giving the P/N and them only costing about $17, anyone got this part number?

U may be running leaner with riva's higher RPMS, maybe its searching for that input, to compensate with more fuel. Maybe it started working again??

Thanks BD!! I'm going to ride it tomorrow, as it can't be that big a deal if I've rode for long without it. Perhaps this is why my afr's always seemed a tad rich :/

Does 11.0:1 at idle with the riva ecu and 48# sound right to you guys?
Could it be rich because of this exhaust temp sensor?

I dont think the ECU uses the exhaust temp for tuning adjustment.

Although it was choppy and I couldnt make full rpm, WOT AFR was very close to the mark. About 12.0:1 from what I could tell. Im yet to set up my RRFPR, but it arrived at my house the other day, so I will install it before too long.
I went out earlier today for my maiden voyage. A few things to note :
-It pulls MUCH harder than I expected, I didnt expect to gain this much from the ECU, but hey, im not complaining
-I noticed after a few short WOT runs I had my oil light blink on momentarily and stutter. I checked my oil, and it was at about 1/3 the way between the bends. I topped it so it was just over half and then I didnt have a problem.
The good news is no water is leaking into my hull, I was a bit worried after doing the exhaust and OPAS block offs. But "the right stuff" does the trick
I think I just need to fix up the exhaust sensor, install the FPR, then I can finally stop wrenching for a while and have some fun
