So, I've read quite a few threads on having the ECU flashed vs installing external fuel management, and for the most part people seem happy with the flash. However, what would happen if something changed? If I have the ECU flashed, then, later on I decide to go with a set of pipes with less back pressure, or opened up the air intake, would I need to have the ECU flashed again?
I have a 17 voyager, and for now, all I want to do is adjust the fuel curve so it feels more consistant and not so gutless at certain RPMs. It wasn't so noticeable during the break in period, but now, when I try to open it up a little, it just feels like it's bogged. I know the ECU flash will take care of it, but later on, I might want to change the pipes to something that sounds a little prettier.
I have used a Power Commander before, and ended up getting the autotune 02 sensor kit. It's just a matter of plugging in a map, and maybe a little bit of tweaking to get it close to where it needs to be, and the autotune will do the rest. But I also know that any big changes require more tweaking or even rebuilding the map.

Folks on the various Voyager forums/Facebook will advocate Ivan ECU reflash 95% of the time over Power Commander. Folks who had PC's and reflash cannot seem to even give them away after they reflash....let alone sell them.

When you send in your ECU to Ivan, you fill out a form that details your current exhaust/intake set up. The ECU is flashed for what you have. If you make any major change to exhaust/intake, you have to send the ECU back to Ivan. You pay for shipping. I am frankly not sure if you have to pay for a reflash at that point. My suggestion is to call Ivan to clarify.

If Ivan does any updates to the ECU flash on his end, he def will update it for you for free....you pay shipping/

All details here....Ivan's Performance Products

Ivan charges $350 plus shipping.

In my case, I got my bone stock 2016 reflashed with 2000 miles on the bike. After 2000 miles, I experienced all the things Ivan's details in the above link that make the stock ECU such a dog. I had a brand new and way better performing bike when I got my ECU back from Ivan last year. The bike runs cooler as well Ivanizing.

I just turned 10K miles. I also had warranty work done at my dealer after Ivanizing....the radiatior fan broke. No issues with the warranty.

Not sure this answers all your questions, but if you call Ivan direct, he can clarify anything for you.

The Ivan reflash will be the best single upgrade I will ever do to my Voyager. I am glad I did not wait long to do it. Plug and play.....very easy to pull and reinstall the ECU

Good luck!

When I had mine flashed about 2 years ago, there were only 2 basic flashes. One flash if you have an air kit and one flash without an air kit. The exhaust didn't make a difference.
With that in mind you really only have that one decision to make... to air kit or not. Looking at the dyno sheets on Ivan's site shows the largest power gains are reached with an air kit. The exhaust does make small power gains but it mainly changes when the power comes on (so to speak). I've changed from stock to drilled exhaust and drilled to V&H several times and the freer flowing exhausts move the power band further up the RPM range.

So, how much power do you want with your drivability? :devil2:

Bought a PCV for mine for the summer so I can ride. Works very well with the right map. Will probably get the reflash this winter when bike is sitting anyway. PCV is not free but a used one is reasonable and with the right map it works very well.

If it weren't for Ivan's flash, I'd have long ago sold my Voyager. It ran very well with the fuel controller, but with the flash, it runs perfectly. Absolutely no comparison. My fuel controller gathers dust hanging on a nail in my shop.

Semidomestic... You'll find Ivan is very approachable to answer questions like yours. Due to the time-zone difference I've never actually spoken to him myself, but we've exchanged many PM's over the years before and after I had him flash my ECU. You should seek the answers to your questions straight from the horses mouth?

I bought my 2011 Vaquero a month ago. Couldn't stand the heat on the warm days. Just Tuesday last week I sent the ecu to Ivan and had it flashed. Got it back Friday.
I have also put a k&n filter in it, wrapped the headers with titanium header wrap, and installed freedom racing dual slip ons. Runs cooler, smoother and performs a ton better. Would definitely do it again!

Yep,
No question Ivan Flash hands down. Don't waste time and money on the PCV. Like auwing1978 said I'm pretty sure after you pay for the flash and you make any major changes or if Ivan makes an update (you have to check back with his web site from time to time for updates I have had to send mine back once for an update) all you have to pay is the shipping Ivan will engrave on the ECU the current flash installed and will put a big Ivan sticker on the other side. Also if you do decide to go with the Ivan flash after he reopens Sept 3rd you only need to ship the ECU if you don't already know the ECU sets in the cage with the relays lift the ECU (the taller of the two) out of the cage and leave the relays (the shorter of the 2) in place under the seat L/H side just forward of battery.

I'll give Ivan a try when he gets back from vacation. It's not like I want to do 0-90 in 1.375 seconds, and I'll never put neighbor haters on it. That would be like running NOX and straight pipes on a motor home. I like quiet pipes, I just want the tone a little deeper and lose the feeling that it's being held back. I had the ECU flashed on my Roadliner and it was a terrible experience. I ended up having to buy a new stock ECU and went with a PC... But, it wasn't Ivan, and most of you guys swear by him, so I'll give him a try.

A benefit of the ECU flash is better slow driving drivability. No jerkiness or stumbles after the flash. Cold startups and driving are also improved over stock. Able to use 5th and 6th gear at lower RPMs also. You will not be disappointed once you have it done.

Hey robbono26 Go on ebay the scrap yards advertise there. I have bought several used parts with no problems also had to return 1 or 2 again with no problems
. Unless you are looking for new then I would try Partzilla.com

A friend in Australia bought a used OEM ECU on Ebay here in the states and shipped it to me. I facilitated the Ivanizing and shipped it back to him. It cost him $200 on Ebay used.

Just sent my ECU in to Ivan. Put on Freedom Performance slip on pipes but just couldn’t get rid of the decel popping with the PCV.
I increased fuel in both 0 & 2% throttle 1750-3000 rpm by increments of 10 but still got quite a bit of popping deceling down from 4 or 5th gear and hitting just below 2,000 rpm. Question: Is there any reason to keep the PCV connected when I get my ECU back? Can I just set the map to all zeros or is it best to just remove? Would there be any need to make any further fuel adjustments to the ECU now? Thanks!

These are excellent questions for Ivan... I presume to know what he's going to say though - so take that PCV on out of there. It only creates one more thing that might go wrong, and you'll never find any reason to make any fuel adjustments unless you want the popping back again. I get absolutely no popping at all with my FP Liberty slip-ons, and they sound very nice indeed. Deceleration in particular, is a very deep, satisfying tone.

This is the only use I've found for my EJK fuel tuner since Ivan arrived - using up a nail in a dusty corner of my shop.

PEG: I got the same pipes and I ordered the quiet baffles to along with them. The only problem I found is trying to slip them on stock head pipes. I had to use hi temp silicone to try and seal that connection. I used the same graphite? seals that were there but when I tightened the clamps I could still pull them FP mufflers off. Just couldn’t get a tight fit. So I used the silicone to stop any potential leaks. Can’t tell if it worked. How did you seal the connection? Did you have to buy new seals? Thanks.

#1 Call Ivan he will explain and answer any and all questions, 2 he told me you already have a computer in your bike ECU that manged the fuel , so why put PVC in it as it fights what the ECU is telling the bike to do so now you have impulses fighting the ECU and may make bike hard to to read whats right and wrong and cause problems along the way, Trust all of us thats had it done just do it and you will be a head of the game.

I didn't buy any new seals, and I'm fairly sure everything bolted up OK. It's a little bit fiddlier than it needs to be, that FP connection, with the extra short piece of pipe to clamp in there, and I had difficulty with the right side, figuring out what was the best angle to tighten it all up at for the least sideways force... Now you've got me worried I need to check it.

I have a buddy local with a Voyager that had a PC he messed with for a few years. He sent in his ECU to Ivan and took off the PC while Ivan was reflashing. Totally different bike when he reinstalled the reflashed ECU w/o the PC

Got the ECU back from Ivan. Installed, removed the PCV, and took it for test ride. So far I’m impressed! No more decel popping or backfiring. Just a low throaty gurgle when letting off the throttle. Makes the FP pipes sound really good. May even try taking the quiet baffles back out. I’m told however that by removing the quiet baffles it becomes a more free flowing exhaust and the loss of more back pressure may effect performance a little. Any thoughts?
