Hi All,

I have a 2014 Wide Glide fitted up with Stage-1 AC and Rush Slip-Ons.
I use the TTS to do all my tuning with. I have developed a Map that I am happy with and works well for the existing setup.

I have just ordered the D&D Bobcat's for the same bike.

Do I keep my existing Map and re-develop it again, or start fresh again using a base map?

Fritzables.

 

I would just tweek the map you are using. There is a TTS tuning sticky with a few of the best tuners around that could give you much better information then I could. I would post there...

 

Thanks rooti.

 

I would raise front and rear fuel tables about 5% all over to start with. These 2 in 1's tend to like being richer. Then you can tune from there. Don't be surprised if you get decel pop unless decel enleanment has already been richened up. To richen decel you make the numbers smaller.

 

Thanks KE5RBD, I assume you refer to the Main Lambda Table?

 

Referring to the VE tables. Narrow band O2's can't change it that much.

 

Thanks James

 

Would it be fair comment to say that unless I am using Wide Bands, to better control Mixture around a certain Lambda value, I would be better adjusting my VE's.

Especially if my Lambda values approach the edge of what a Narrow Band can accurately measure?

 

the only two systems I am aware of that run the Wide Bands and are active is the Thunder Max and the PCV with autotune module. The PV can run the wide bands but only in Autotune mode. You really don't even have to have the O2's hooked up. Whether the Narrow bands are at the edge of their capability or not they only are active in closed loop. When cold they are inactive. You have other sensors that control the mixture also and you won't get very far if you unhook any of them, the IAT and Engine temp sensor, Map sensor, throttle position, Rpms to name a few. The O2's only measure the oxygen in the exhaust and give feed back to the ecm which interprets it just as it does from the other sensors. O2's are for emissions control. Not saying they don't help keep the engine AFR more accurate, but they are a very small portion of the AFR control.
