Can anyone tell me how I recalibrate the throttle position sensor on a SC 58 mm throttle body. My bikes running real rich Sense a number of upgrades.

My bike is 2010 Fatboy I have just installed the following onto the bike 

S&S 107 big bore kit 

S&S superflow heads 89cc 

Set of S&S 585 cams 

SC 58mm throttle body with 4.9 high flow injectors and SC heavy breath intake 

V&h fuel pack 3 tuner

The bike will idle but the moment you try to ride it surest and sputters 

 

I am at a bit of a loss as to the problem which is why wanted to check the TPS but I know how or the values as I am assuming it would be a volt value 

Cheers 

As a member has mentioned , you have major mods.... From what I read the FP3 seems to have good reveiws for Stage 1 and Stage 2. Going off the USA sites, people that have some minor hiccups in their tunes for the FP3 get in contact with V@H , (dont know who you contact in Aus), send them, (through their app), the tune in your bike with build and problems you may be  having.. They check and tweek the tune and send back the tweeked tune for you to upload to your bike... Hopefully all is good , or you may need to do a few auto tunes to dial it in better ...Seems good in theory , but most seem to be happy ...

A few questions for you...

Did the FP3 in their data base have a map close , similar to your mods for you bike ???... If not , What tune did you install, with what mods ???

V@H also make the FP3 Pro , (more expensive), which comes with  Wideband sensor connections etc,,.. I take it their product for DIY  tuning more advanced motor work and mods, which your bike seems to be a candidate .....

I dont want to get into a debate on which tuning device is better than the other, but with the upgrades you have done to your bike, I would want a reputable tuner work his magic , and get the best bang for my buck after spending all that money on motor upgrades .....  

Just my 2 cents worth ,,,,,, Good luck .....

 

Thank you for your response, 

The fuel pac 3 didn’t have a preloaded map for the work I have done but before I started the bike after the engine work I contacted V&H and provide the details of the work done they provide a custom map for the bike which I installed before kicking her over for the first time. 

The at idle seems fine and sounds amazing I did tried the auto tune function but as the bike tune was so far off that made the situation even worse bike wouldn’t run at all.

I have just gone back to V&H with the issue they got me to up load the ECM and have provided an updated map which I haven’t uploaded as yet as I haven’t had the time to work on the bike over the last few days they are also asking for the manifold absolute pressure once the bike is at operational temp.

I will say that the response time from V&H with the tech query’s has been good however the jury is still out on where or not the fuel pac can deliver the results I need.

There are a number of high quality tuners on the market I based my choice on a number of things at the time recommendations from others including the local HD dealer and that the tuner was less intrusive than other little ironic given the work I have done to date on the bike. 

Hopefully V&H can come through otherwise I am in the market for another tuner
