Hello. We have been riding here for the past couple weeks. Early start to the season. Here is hoping all us dootalkers have a great 2018 season.
Update on Dial-A-Jet. This season i have a dual probe EGT gauge hooked up to monitor the exhaust gas temps on this etec engine with Dial-A-Jet full rich and full lean.
I have been told by more than one person that this system just does not work for adding fuel. Not trying to prove any one wrong or right. Just trying to get some Data on this Gizmo to see if it actually works.
Here is what i am finding. Dail-A-jet full lean on a given day.
Midrange 6000-7000 rpm EGT are very high cruising @ 6500 rpm for one mile. Temps creep creeping up to 1280F before backing out of the throttle. This is steady throttle no flipping of the lever at all.
Same setting full lean, or stock fuel curve Wide open throttle for 1 mile. EGT are 1225F max.
Now with the Dial-AJet full rich position. Same day.
Midrange 6000-7000 rpm EGT are still very high cruising @ 6500 rpm for one mile. Temps still creep up to 1280 F before backing off.
Same setting full rich. Wide open throttle for 1 mile. EGT temps never go over 1175F Max. Most of the time 1150-1160 range. Repeatable back to back runs no change.
Sooo. I am thinking this Gizmo is working. Adding extra fuel to pull egt temps down 50 deg F is not real big, but good enough to think it is working to some degree.
I have run this thing from -16 deg C to -1 deg C. It works best on the cold days. Warm days the sled run slugging having hard time pulling rpm. Also verified Y pipe color after full throttle runs. There is a significant diff in color in side the Y pipe full rich vs full lean.
