What are thoughts on the Wiseco fuel management system? I had never heard of this one until setting up for a maintenance check. I guess its a self tuning tuner. I found them for around $200.

 

Its the same thing as the Dobeck load based system. theres a number of them on the market under different names. It allows you to tune the EFI as if were a carb, and you dont need to hook a computer to it to make any changes. Simple and inexpensive.

 

Features Benefits
• Plug N’ Play installation • Simple to use and understand
• Easy push button operation • No computer or dyno required
• Easy air/fuel ratio
adjustment
• Easily adjusts for modifications - intake, exhaust,
cams, etc.
• 3 basic zones of operation • Similar to carburetors
• Uses OEM base code • Does not scramble base code

So, I'm a little curious. If a computer or dyno isn't necessary how does one know what the afr is at while making adjustments?

 

Just like we used to do it ten years ago. Check the plugs

 

When hooked up, how does this differ from say a power commander? Sorry for the ignorance but I'm not very mechanically inclined.

 

I had one of these on my FI dual sport last year.

Worked great after i did airbox mods and a full exhaust.

The unit plugs in-line with your fuel injectors. All you are doing is changing fueling under given loads and throttle positions. Its hard to fine tune, adjustments are made by pressing + or - on the programer for each "mode". You have a limted range on what you can add or subtract.

On my dirtbike it worked fine, because so many people used them and posted what numbers they used and I went off that as a base and just adjusted it to my "seat of the pants" feel. I would NOT want to use this on my dyna. It would be a PITA to tune. stick with a Power Commander V

 

No I put it on a few moths ago it came with a set of numbers and I know it's out of wack. I put a thunder header on last week and the dang thing almost cooked my right leg from header heat. 😡 That was the main reason I bought it was to reduce heat. It happened to rain on our ride and I was glad it did. So now I have a Stock air breather and a thunder header. Does anyone no of a good set of numbers for that style of set up. ?

 

Ditch the stock breather. It's a must with a full pipe.

 

I spent the last month learning the TTS MasterTune, it's VERY complex. Only reason I did this is because that's what my new (used) bike came with. If it didn't come with it, I'd have gone with a PowerVision. I have no plans to go past Stage 1, and the MasterTune is definitely overkill IMO.

I agree with others that DynoJet has really good service.

RE: FuelPak, my understanding is they only have maps for V&H exhausts. Someone correct me if I'm wrong. For the price difference at the time I checked last month, PV was $70 more than FP3, and the PV has a lot more capability.
