Hey Ray,

glad to see someone move that air temp sensor first! My 2006 Nomad had the worst pinging problem and I tried the resistor and TPS changing and nothing really worked to the level I liked.

The resistor sounded promising as I saw it done on Gadget's page. After failing and not stopping the pinging I bought a TFI and was done with it. Even with the TFI the ECU tuning by air temp was a little off. The bike ran well enough but I found that if I tuned the first pot in 60 degree weather compared to 100 degree weather the tuning was drastically different. The stock ECU was still messing with my modified richer settings.

Thinking about why the resistor mod failed it suddenly dawned on me (I hate it when that happens!). Gadget's site shows a spread sheet how the resistor changes based on the ambient air temp (outdoors). That's the problem, the air temp behind the dog bowl where the sensor is located I've measured 275 degrees! No matter what resistor you had at 275 that bike is still getting leaned out to the max by the ECU.. that's the problem, as the bike gets hotter the ECU keeps getting leaner to maintain the air/fuel ration which makes the bike hotter and so on and so on.

Well yesterday I did your mod and removed the air temp sensor from the right side dog bowl and moved it to behind the chrome covers on the triple tree. I had always ran the standard 3,5 1, 9 on the TFI or near there...

Just to see if this would work I turned the setting on near the minimum 2,2 1,9 and put mid-grade gas and took a 140 mile ride this morning in cool weather. I also mounted the crash bar covers which help promote pinging in warmer days by keeping the engine warmer. I was half expecting to hear that death rattle all day long!

The bike ran way different, didn't ping, and riding 2 up averaging a true 70-75 I got 40mpg's and the Nomad just ran better. I guess the ECU operates better with the air temp sensor reading 65 degrees instead of 275 behind the dog bowl!!

I almost wonder now if everyone moved their air temp sensor if they would need a aftermarket fuel processor?
