Car wouldn't start remotely this morning (it's kept inside a separate garage) - but, like the other times, it started fine with the interior starter button. Emissions system problem warning message came back on. Plugged in the Flashpro and opened the Hondata app and it said P2183 - (after googling = Engine Coolant Temperature (ECT) sensor #2). Tried to clear the code via the app but it didn't work.
So, it makes sense that I would get an error like that since the PTR kit (and all the other kits I've seen) connects into the ECT2 circuit (and the OEM ECT2 sensor at the back of the radiator - down low, driver's side - is no longer connected to anything afterwards). And that would kind of explain, maybe, why my car overheated that one time. (But what doesn't make sense to me is how intermittent the warning/problem is - seems to me that once I disconnect the OEM sensor, bam, there should be an error code/warning that doesn't go away?)
Anyway, after a little more googling, I found out that there is a Hondata/Flashpro option to "uncheck" the ECT2 sensor (basically telling the ECU to ignore it being disconnected). Since I brought my laptop with me today, I unchecked the ECT2 box and reflashed the car a few hours ago. Went out to run an errand a little bit ago and the car still wouldn't remote start and all the error messages were still cycling through (although the car ran OK). Will check again in another hour or two when I leave work for the day. Sorry for the crappy pictures ahead!
Btw, I did spend like a half hour on the phone a few days ago (before the overheat) with Hondata and the rep patiently helped me troubleshoot/reflash. At 0:34 of Hondata's youtube video
, they say choose the "flex fuel enabled stage 2 +6 psi" but my Hondata manager doesn't have that choice:
3rd choice down has "flexfuel enabled" but not stage 2 and +6 psi. The Hondata rep told me to choose the option 2nd from the bottom (which is the one I had been running - my Flashpro is a race only model) and inside that, check the ethanol enabled box under Ethanol:
Oh and btw, if you have a catless downpipe like me, you'll have to uncheck the secondary oxygen sensor enabled box under Closed Loop:
Unfortunately, the Hondata rep I was talking to, never mentioned anything about unchecking the second ECT sensor enabled box under Misc (revisit the second picture from the top) even after I had told him that I had installed a flex fuel kit... Hopefully, this will solve my problems - keeping my fingers crossed!
