No one has any advice?

 

Ganooch- I'm not really qualified to be of much help, but what I have been learning so far is that the log data will help determine where the issues are with the tune. are you capturing logged data on these runs? Since you have a FM unit I would think that Jamie or someone at FM could advise you on 'tuning up the tune', so to speak. I don't have that luxury since I bought my PV2 through an HD dealer, and DJ's direct tech support is marginal at best.

IMO I would avoid the areas of detonation while riding until it's sorted out. it's definitely not good for the motor. How are you determining a loud detonation event- a loud rattle or ping, or an exhaust pop/bang?

 

A very unusual issue you are having here. Usually of you get to the point of actually having the map loaded, and that runs okay, then moving to Autotunes and working through that, is a fairly painless process.

The PV sets all AFR cells to 14.6 and then subtracts 4' of timing for the AT session so typically the bike may run slighly rougher than when not in AT mode.. but nothing like you describe. You talk about lugging, and then detonation or winding up and then detonation.. it sounds like the bike is just not firing correctly then starts to, but maybe it's loaded up with gas and boom.. detonation.

A question and a couple of suggestions:

Did you call FM and ask for help with this? That is the very first thing to do. I assume you did.

Did you install the pipes, AC and PV all at once? I'm just wondering if something isn't amiss, and just not obvious under the no AT mode but becomes obvious when AT is initiated. Got those headers seated properly on the heads?

Can you go back to the Original Tune and tell us how it runs. You should have saved the Original Tune when you married the PV to the bike. Even with the AC and the pipes you should be able to ride the bike without issue that way.

In fact, you could do a AT from that point and see what happens.

Are you sure you've got everything with the headers/slip-ons/AC all installed correctly and no leaks and obvious physical issues?

I know little about these CFRs but from what I gather they are quite low restriction pipes, I'm wondering if that has something to do with this? You might even think about putting the stock pipes back on... just to see if this problem goes away. I'm not trying to say your pipes are bad, but just trying to narrow down the possible issues.

I don't have a map to give you. There might be a map for your config on the Dynojet web site you could download and try but I'd still be eyeballing all the other things you might have touched doing the mods.

Call FM too, unfortunately it's now the week-end, but give them a call if you haven't.

 

Ganooch, Make sure your 02 sensors aren't reversed, Black plug Goes to rear cyl. (IF Rushmores are the same as older bikes) I know nothing about Rushmores, Other than some things are different.

 

This is my first post on this thread. I'm up to page 617. Lots of smart guys on here and I think I have a good grasp of what's going on. But I have a few questions that I haven't seen asked yet . I know staljim69 will know the answer to these questions.

My bike is a 2002 deuce

1. Fuelmotousa sent me a map that is tps based. My original tune I removed was map based. Would it be more advantageous to have a map based ve table? Which is better and why?

2. I've read about manually smoothing the ve table in the edge cells you don't hit. I assume this means to remove a spike or a dip and put in a number close to the number of the adjacent cell that I am hitting. Is this correct?

3. I know the pv won't add timing. So once my ve is dialed, should I globally add a degree or two to the whole table, then ride and log, and use log tuner to pull it back out. Keep repeating until I have all timing advanced within a degree of a knock, then globally remove two degrees. Or am I overthinking this one?

Thank you for the feedback on our new website [/QUOTE]





Good move on the web site much better.

 

 

My riding friend just purchased a PV1 and installed in on his bike. He previously had the Rev Performance ems installed. He got a new map from Dyno Jet to install for his engine build. He tries to flash the ECM but gets an incompatible message and cannot load the tune. Any ideas as to what he needs to do?

Thank's

PS - he has sent an email to Dyno Jet but being the weekend no response.

 

Are all the O2 sensors the same color on harleys? I looked at my bike for a good 20mins trying to see if there is a color difference between the two O2 sensors and they both look the same.

 

The sensors are the same front and rear. The connectors they plug into are different colors front to rear.
Later model bikes have sensors with smaller diameter threaded area than the earlier bikes.
