Has anyone done this yet? Were parting out Harleys where I work and we got a couple with drive by wire. Im assuming change the throttle bodies and maybe a module and wires?

 

Cant remember seeing anyone posting about doing it in here..

Although several have done the EFI to Carb.

Personally I would stay with cables. most fly by wire seem to have a strange lag. (at least in cars, never had a scoot with it)

 

Ill stick with the cables

 

Yeppers I know the 10's does.. when My Son got his new St Glide in 10 and I rode it,, I keep killing it at take offs several time afore I got used to it.

Agreed with sticking with cable. Electronics are nice (like EFI when it's below freezing out), but some things simple mechanical actuation does just fine.

 

The great thing about Harley's TBW system is that you can install their factory cruise control by simply changing the left switch housing out with one that has the cruise control switch. The switch assembly uses 4 wire CAN bus so each switch sends a digital message to the ECU, making for a modular system.

I believe the handlebars need to be changed with bars that accept a twist grip sensor (TGS), along with the throttle body that accepts a throttle control actuator (TCA). The idle air control (IAC) motor gets deleted since the TCA now handles idle speed control. The ECU uses different drive outputs for each. Furthermore, I'm not sure if the ECU would have to be changed...this would be dependent on model year. Lastly, the harness may not have the wires for the TGS or the TCA, so wiring may need to be added.

This is definitely a project I plan to take on with a buddy's '14 Heritage Softail. In that model year, the CVO Softails had TBW so my guess is that they used the same harness across the Softail line. The harness probably has wiring for both an IAC and TCA, and they just use the connectors for the installed system while stowing any unused connectors. If they did and the ECU/firmware is the same as a '16 or later Softail, it should be an easy upgrade.

 

Have you done this yet? If so how did everything turn out?

 

I’m assuming your ecm or bcm is not equipped to run tbw. Your handlebars also have to be slotted for tbw.

 

While true, it's because it's programed that way.

If you have a PowerVision Tuner ( I assume TTS & maybe a few other flash tuners can do it too) you can program that out. You can actually program the TBW response to be 1:1, which would give you a super sensitive, albeit twitchy, throttle response....
