Temps 320+ and tuning not helping...
I've been changing up which sensors to monitor on my PV2, hoping I can get better insight. Well, this morning I added my Idle Air Temp sensor to my gauges. When I fired her up it was reading 95*F. Again, I live in SoCal, and this morning it was 62*F when I rode out. It's 65*F now. The last reading before I cut the motor at work showed the IAT at 129.2.
Now if I understand this right, the VE and target AFR are measured with TPS, RPM, and the air density, in which the IAT plays a big role. If the outside temps are hot then the air is thinner and the bike compensates with the VE to get to the target AFR. If the bike does this the it sort of runs in a leaner state. If it's colder then the air is more dense and it runs richer to achieve the target AFR.
If my IAT is reading the intake temps are hot (thinner air) then it is leaning out the VE. Leaner = hotter.
Can this be my problem?
When I returned from deployment I was having cranking issues. Someone tipped me about the IAT and to clean it. I used some electrical contact spray to hit the sensor hole in the intake. A little gunk came out and it did help with the startup.
Would taking out the IAT and really cleaning it help or should I replace it?
Any help is always appreciated!
