Quick question as I sit at work.. After buttoning my project up last night, the tach reads about half normal. I just installed the Dyna module on my Electra Glide, had to wire it all, not just plug and play.. Wondering if anyone had been there and knows what I need to check first..
Thanks,

 

Is your tach set up for singe fire or dual fire?

 

Yepper. I'd bet on a single fire ignition and a tach set for dual fire. Either a setting or use a tach adaptor. Or multiply.

 

Sure sounds reasonable.. I just got home and double checked, I did have it set to single fire. Switched it to dual, didn't notice much change, but I didn't get to ride it to verify. Seems like idle is still about 600 on either.. Just during my ride yesterday, what would normally be 3000 was reading about 1500.. Got a tornado warning right now, so I'll have to wait to do more.. Don't care for the hail and wind, guess I'm fair weathered.... Since this was born an EFI bike, wouldn't the tach be calibrated for single fire anyway??

 

harley ignitions are one pulse for the tach - some tachs are 1 or 2 pulse they have a duel sender and a thin brown wire needs to be cut if you are not runing a stock harley tach

its always at the exit if the tach wires pull the covering back and look for it if its not an OEM harley tach

 

I got some clear weather and played with it a bit.. Took it for a ride in single, tach about half, all speeds(didn't seem to do that earlier, might need Key off input to switch).. Then I switched it to dual and got normal RPM.. Guess that was it, thanks for the input guys!! By the way, I also switched it to curve #1 while I was at it, seems to like that too, all I need is more switches to dick with!!

 

I am about to go through the same process on the switches, not in front of the directions, but seems #1 is the most advanced. If memory serves me you start with #2 and if all seems good to try #1. Thanks for sharing.

 

Yea, I followed those instructions and while impressed with the way the bike ran since the major rebuild, #1 made a pretty decent difference. The curve looks to be much more aggressive, ramping up much earlier in the chart I saw.... Really need to ride it a bit more to make sure its the way I'll keep it though.. In fact, I followed their time it by the LED procedure, I may throw a timing light on it to make sure its advanced enough.. Being new to it, I'm a bit skeptical of its accuracy, but its a great way to begin the process!

 

Thanks, and keep us posted on the accuracy. I am planning to do the same.
