Living Legend
Symptoms. 2012 Roadster with TORS, Ramair, along with a Hanso map, unrestricted secondaries, with +5% extra fuel to prevent popping on decel. Been running this map for years.
Last year, on cold engine start ups, the bike fires up fine then hunts for about 30 seconds erratically until the idle settles down. It started doing this early last year. No other symptoms/problems though so I rode it all last summer. This year while in Florida in January, whenever I got to an intersection and had to wait for the light change, when giving it a bit of throttle, the bike would hesitate, stumble, sometimes stall and sometimes backfire. Once underway, there was no other problem. Drove it like that for a month. Decided to check it when I got home. Purchased a TPS.... just in case.
Back home now, I noticed something while checking the TPS. With TuneECU hooked up, I initiated "Adjust ISCV" and got .60 volts. Nothing to adjust here. I then double clicked for the second test and initially got .72 volts but after a few seconds it dropped to .66 then to .60 and then climbed back to .72 and stayed there. Did this a couple of times whenever I initiated the "Adjust ISCV" function.
Is this normal? Once it does the weird dance, it settles down and doesn't change at .72. I then clicked for the final 15 second part of the reset where it tells you not to touch anything.
Thinking this wasn't normal, I replaced the TPS with the new one I had and got the same weird dance on the .72 volt test whereby it initially goes to .72, then cycles down through .66, then to .60 and back up to .72.
I have checked all the historic TPS threads and haven't read of anyone getting this particular condition. Is this normal???
I'll test the bike again later to see if I still have the hunting condition on startup. Still can't drive here so I can't test for a stalling condition at intersections. I did have some gasoline in the old TPS which might have cause a problem with it????
