Zuteduff, You are running a Delphi FI system and it is far different from the MM system that the OP is running. They have nothing in common. One of the problems with the MM system is it's small Dual runner system. I had a 1998 FLHP FI bike with the MM system and spent close to $3000 dollars trying to make the bike have more Torque and HP. The best thing that an owner can do with the MM system is to remove it and replace it with the Mikuni carb of the proper size. Later Fairshake

 

Thanks Zuteduff. I use Ronnies all the time, and buy from Surdyke. That YouTube video was exactly what I needed. I'm not sure if it is the TPS. I had a tech at my local stealer hook it up to his computer and there was not error codes. Now, reading your earlier post where you didn't have any codes either until you replaced your ecm has me wondering...

 

Question; Can you go in and adjust the settings to your specs, or is it limited to finding the closest canned map from S&S? Thx

 

that's a negtive....Mine is a MM EFI>>> .they didn't do delphi till 02 i believe...

 

if it's doing it all the time and not only when it's hot...you might check the volt readout on the TPS. when i dropped my TB all the way to full closed, my reading was .191 when it should have been .275 at full closed.. I figured mine was bad since it became worse when hot....yours May just need adjusting and not replacing....

 

Zuteduff, You are quite correct sir. I was looking over the top of my Wally Worlds when I read your posting and thought I saw that your bike was a 2010 model, not purchased then. Please excuse an old man who misread your op. I do however stand behind the rest of my posting about trying to tune that system for performance. Take Care

 

quite alright sir.....us ole men do make mistakes on occasions...and you're right about the tuning....

 

This video maybe helpful, mainly about installing software.

 

I bow in your general direction! Using the YouTube video you posted, I was able (for the first time I might add) to use a multi-meter. My TPS read .041 (not sure what setting to use on the multi-meter, I just set it at 200m?). I was able to get it to .275 but the bolts that hold the TPS have glue in the slots for the torx bit? I used a pair of needle nose vise grips. Hopefully I got them tight enough that they won't back out under vibration. I then set the cold idle at about .652, then the warm at about 950rpms (based on the not so specific factory tach). Initially, it seems that fixed my hesitation at 2850-3150 rpms, but I'll need a longer run to make sure.

I'm still looking into an upgrade, but hopefully this will keep me running through the summer!!!! Thanks to all for the input and a giant thank you to ZUTEDUFF!

 

Hope that fixed it my friend.....Yeah, that crap they put into the screw heads is a pain. used a small ice pick type tool to remove it from mine then had to tap on the torx socket to seat it good....if you get a new TPS, it comes with new screws minus the epoxy...

I know that mine is running better now that it has since I bought it 4 years ago.....
