dynojet PC-5 install

[crazyspyder]

anyone have any tips or suggestions for a dynojet power commander 5 with auto tune? going to install this on my 2012 spyder RT SE5 , I have my cats removed and after market muffler -which requires me to get a fuel management controller. JB was ok for awhile but really didn't fit my needs .

I could not come across anyone to dyno a spyder, thats kinda what the auto tune is meant for. Works great!

power commander 5 with auto tune-dynojet brand ; sorry, I meant to say - I need help and have questions on the install. need to know if I need to use that o2 sensor that came with the auto tune for one? most likely will have the dealer install it.

AFIK yes and you need 2 they are wideband O2s unlike the OEM
. Someone correct me if I am wrong.

to have it work properly you have to use their parts. Some have just added the sensor to the pipe. Does require welding on the threaded adapter. If your dealer is installing it they should know. If they have not done it before find someplace that has...goid luck..!!

1,- yes you need to instal the sensor which comes with PCV and also retain factory sensor as is
2,- if you follow instructions when hooking up with power/battery - it will constantly drain a power from your battery so i would suggest extra fuse box from Tricled.com as i have or possibly ad on in-line switch
3,- i found manufacturer's - Dynojet help desk to be the best and they even set up my unit via net - these guys are hard core Pros

#3 good tip, always a good idea to check with the manufacturer for tech questions. I found the same to be true with Two Brothers Racing.

Out of curiosity, what led you to this conclusion? Is your bike now running too lean?

[stewartj239]

Does require welding on the threaded adapter.

Is this required for the PCV or the Auto Tune install? I was under the impression that both were just a bolt-on.

To the best of my knowledge, you will need to have a bung welded to the stock pipe to install the PC sensor...and you will have to retain the old one as well. If your dealer has never done one, you may have to hire out the welding/drilling of the pipe.

my spyder in the shop for a few weeks and when I checked on it, the tech told me / suggested I get a fuel management system. running lean enough to ''pop'' at dec.
I will be calling dynojet in the morning and will post-whats up! after reading install- I believe that if using PC5 and auto tune in conjuction , you will not need to weld o2 sensor bung because the PC5 is already connected to both o2 sensors, and the auto tune should pick those up....I hope!

Yes, please report back what you find out. I am very interested in both. If there was a map for the cat removal and Akrapovic, then I'd be set as I wouldn't need the Auto Tune. The only maps they have is a stock map and one for the Two Brothers silencer.

[5PYD3R]

You will have to have another 02 welded into the pipe. Even when using them together. Not really a big deal, any muffler shop should be able to help you. My buddy is a welder and drilled and welded the new bung in no time flat. Might be different now but when I got my auto tune there were not bike specific directions that same with it. Can be a little overwhelming but all in all, not bad. You have to enable the auto tune in your PCV software also.

Even if they did have a map for your setup, I would still recommend the auto tune. The auto tune will "fine tune" the setup. I started with the recommended map on mine and the auto tune made some decent changes in the fuel map and got rid off ALL popping.

But is the welded O2 required for the PCV or the Auto Tune. If I just go with the PCV and get a map created, is the additional welding required?

No but maps are limited to very few,.

If you just do the PCV you will not need to do any welding. Even with the added trouble (which isnt bad) the auto tune is well worth it!

Which Auto Tune did you go with? I see that the AT-200 has a single O2 sensor while the AT-300 as two sensors - one for each cylinder.

I went with the single, the dual is for 'v' twins in specific - and that's what dynojets techie recommended to me. bad enough you have to weld 1 bung... don't want the hassle of another.I get mine FRIDAY..yeah!

The Rotax is a V-Twin. Did you meant 'Specific V-Twins' as in Harley models?

I would think an O2 sensor for each cylinder would be the best of all worlds as I've heard that some Spyders run lean on 1 cylinder and fine on the other.

yes sir, their web site is kinda confusing on the issue so I called to clarify. ONLY for v -twin air cooled engines as in Harley motors.

I have not used A PC V but did plenty of tuning on Corvette ECMs. If the TB only has 1 injector then one O2 should suffice. If there are 2 injectors on the Rotax () I cannot see how you can get a good tune from one sensor. There are 2 O2's correct? If so they are measuring each cylinder. Each injector will need the BLM's adjusted for proper tune and I too have read some Spyders run one cylinder lean. Maybe someone with more Rotax engine knowledge can jump in here......

This is the link to install on the 2013 even though it says 2010

On my 12' RS-Two injectors total (only one per cylinder). One o2 at where the "Y" pipe collects before the muffler.
IMHO- to do it right with the auto tune, and if spending the money, the dual channel would be better.
Single will work, but the dual is ideal. The cost difference is a minimal upgrade.

Now with that being said, I still tune old school with a base map, an AFR gauge and some ride time. Works for me.

All are going to get you close enough with little, if any issues.
If these were race motors it would be different.

The RTs have two OEM O2 sensors, but the RS, at least through 2012, has only one.
