Who's running an ignition module and PC111?

[dirkdiggler]

I just bought an Ignition module on Ebay. I bought a Pc111 last week from Allen. I know the module showed no Power gains but a Buddy of mine that setup a Nytro with combined with an exhaust and filters claims they are getting 114 MPH out of a Nytro on GPS.

they dont come with maps pre-installed like the motorcycles do. you need a reputable shop such as ulmer or excell to provide maps for you to see ANY change from factory settings. or you can play with the settings on your own to create your own maps with products like the air fuel guages to help you "tune" the sled in better. ski

I'd be running the Maps My buddy Created for the Nytro I talked about in my first post. I was just wondering if anyone on the site was using the combination and if they liked them

i have the filters, exhaust and power commander on my nytro. i havent really "felt" a huge difference in the power. it goes through more fuel for sure. and i still have a stumble and a midrange burble.

i believe it is a rich condition. it is alot better when it is colder but, when it gets warm it goes through more fuel and feels less crisp.

i believe adding fuel to the curve is the culprit. the stock efi still adjusts for temp but you are adding or subtracting fuel throughout the TPS settings (by percentages, plus or minus 1-10% per tps setting and rpm). the efi cannot over come that, and the sled gets too fat when it gets warm out, too lean when it gets colder.

truely i believe like all factory settings the sled will come too rich and needs fuel taken away from it, not added. but that is just me thinking, no real facts to back it up.

one big thing that messes with the nytro is the internal engine brake reduction process. it holds the rpms higher when you let off the throttle to avoid engine braking from throwing you over the bars. i wish we could disable that feature. i dont mind engine braking, but i mind tinkering with fuel settings to get rid of pops and stumbles created by the ebr system.

i talked to allen ulmer about the ignition module for my application, he said without running premium fuel there wouldnt be much gain. i left two strokes to get away from premium fuel so, i opted not to persue the ignition module for my riding style.

most four strokes shoudl come lean, so that they meet EPA standards...it is almost opposite what we think, but from what I understand the 4strokers want more fuel and that is what we are trying to accomplish with the AF and better mapping...

Ya the premium fuel thing is the crappy thing about it

I thought the ignition controller was not really needed on the Nytro, since it had pretty good timing in stock forum. I thought Allen said that somewhere.

I have been running the PC3 and ignition module since october, I bought them from Ulmers with the map already set up and he claimed 8 Hp, I will agree with this, I can feel the extra power, the front end pulls up alot easier with the PC & IM. I took off both the PC and IM and i could literally feel the difference. Yes i also do run 93 octane

that's cool. Have you ever run your sled with a GPS? If so what kind of MPH are you seeing? What kind of MPH are you seeing on the dream meter

 

[YamYboY]

umm I never ran GPS, I have a 1.5 track, but I've seen 100mph only once, I notice the power on the low end mostly

Do you have the full exhaust or just the header?

 

[skidooboy]

at the time that was written (march of this year) i only had the stock header and an after market can.

now i have the vector excell header and a yoshimura rs-5 can to be put on.

what you need to know about the pcIII is, there are no maps on it from dynojet it comes with nothing. you have to get them from ulmer or excell and there are not many choices.

or you can buy a pc5 and make your own maps, which is time consuming (and expensive).

hoping more map choices come out preseason so we dont have to mess with them in season. ski

 

[SledFreak]

Ya, I know about the maps, since I had them on my Apex from Allen. Looking to hear how much of an improvement with the Excell header.
