FE/FC FE350 EFI tuner - JD or Dyno Jet

anyone with the JDJetkit PowerSurge 6 - how do they like it? what else have you done (exhaust port, snap, full system etc)?

how would you (or would you) compare JDJet PS6 to DynoJet PCV?

We've seen Robertaccio's write-up on the PCV.

I have the JD tuner, map switch, TPS adjusted, fmf mega and 4.1 on my 350. IMHO better money can be spent elsewhere.
Seat of the pants I didn't feel much if any difference with the setting changes, the bike does sound more crisp though.
JD aftersales support is useless, I emailed them few time asking for setup help and specifically about using it with and without the TPS adjusted and the response was actually quiet rude.

If I was to buy a tuner again it would be a Dynojet

I have the Zip Ty power commander with a best dual sports end cap. It's better than stock. It was not as good as I was expecting. It really needs a full exhaust system on it to take full advantage of the programmer. Even with gear changes, programmer, and exhaust end cap there is still no real hit on the bottom. This is my first 4 stroke and I'm still trying to figure out the set up.

You should have at least a Powercore slip on silencer. A full system with resonator is much better, yes. The 350 does lack low end grunt you are going to get from the 450s and is more of a top end bike. In the future, I would steer away from BDS products.

Bigriver - What "hit" are you looking for?? Hits anywhere in the powerband will just loose traction. 90% of rider will be slower thus most brands building smooth tractable motors now.

It's known that the KTM 350's lack bottom end punch. This is especially true because someone over at KTM decided to put even smaller head/valves in the Husky 350's. The way I increase the bottom end is with a resonator header (Akropovic, PC, FMF, etc.), Zipty porting that allows more air to flow in from idle up (not just top-end), and the powercommander allows me to not only match fuel mapping, but add more fuel from the bottom with accel functions. So the end result is a wider, smoother powerband from the bottom up.

power commander with accelerator pump function activated. It wont be much if any faster, but it will give the more of the hit feel you looking for

So you are saying the valves are smaller in the Husky than the 350XCFW?

i have ridden 2 strokes forever and having trouble getting use to the smooth power. In stock form it reminded me of my xr100 that rode around with my kid.

I am not exactly sure what kind you are trying to compare the 350 too. Compared to my Italian husky 310 my 350 blows it away, however, in comparison to my yz250 (with vforce reeds and a pro circuit exhaust) the power is more subtle off the bottom. However, it pulls much farther. I have found the 350 to have much more power then I expected it to have. Keep in mind, I do not have the husky 350, I have a '14 350sxf, but I am assuming the bikes should be comparable. And between the PCV and a JD power surge 6 the PCV will win hands down. There's a reason why more race teams use it then they do a JD power tuner, but you will pay more for it!

IMHO, it seems so many want instant gratification, changing bikes and especially from one type and size to another, takes time to adjust. For me that time is about 12 months.....I'm slow to get dialed. that's roughly 2-3 rides per month. Get out and ride your machines torture test yourself leave the comfort zone don't cut corners, once the bike feel is there then get down to cutting edge dial ins. Again no calling out just a thought process, of taking time to get a really good feel for the machine.

I did my first ride with the JD Tuner this past Sunday.
Dual sport event- lots of rocky slippery rooty singletrack.
No other mods to the bike.

It performed as expected and hoped for:
The off idle and low end leanness and jumpiness were smoothed out.
Nice grunt transition in the midrange.
Not much WFO due to the conditions, but the few times I did were just fine.

I kept the 'recommended' settings that were pre-programmed in the unit.

I don't have access to any re-flashing.
The JD option worked out fine for my purposes.

One helluva bike, this FE350.

what were the settings that came with your unit? were they different the what was listed in the instructions?

Can you get a vortex ECU for that bike?

I went through the sequence to check prior to riding.
They were exactly what was recommended in the instructions.

Aren't the KTM/Husky twin's ECU end user tunable?
There are guys in our riding groups here in Aus that map the last of the Bergs. I assumed the newer bikes would be the same.
You wouldn't need to add on a box if that's the case.

Yes seems like it. Was talking to the KTM dealer and the head technician said he can write a custom map on the diagnostic tool for the dirtbikes.
I'll try to find out if it's possible for the huskies when I go in the dealer. I know for a fact the smog controlled US models are locked but the other models should be possible.
Then again access to the diagnostic tool is not possible if the dealer is not willing!

Update: I talked to the local Husky dealer and the "normal" diagnostic tool can only upload maps not edit them.
On the other hand there is a tool available from KTM-Husky which allows them to edit and make maps. Some dealers here purchased it some didn't (yet).
The local KTM dealer has it here has the KTM version, but it is not supposed to do both both KTM and Husky I have been told.

I know this is aimed at the cruiser market, but here's a little on DynoJet Research. Our crew member brought his FE350S into the facility for them to use for the FE350S test mule and for mapping setup. with great success, see other thread. for help choosing what to product use.
