its not hurting me to be running the pc3 right now is it? my look at it was you could always have a perfect tune with a fuel controller no matter what mods you have, and since i already have it it would hurt me i didnt think.

i wouldnt waste my money on one right now because of only being piped, intake and no lid. but i cant just stop there and call it good. lol i like horsepower even though right now i have just alittle to much. i havent actually thought to my self on the track that i couldnt hit a jump because i didnt have the power

I finished my build last summer and went to Saint A's. While draggin Choke I couldnt figure out why my Big Bored Ltr was no faster then my buddies (nearly stock) Ltr with an exhaust and CB. Not to mention I was running HOT and white powder started to form on the exhaust. I could tell a difference in torque between the two but We were neck in neck when draggin. I couldnt figure it out till one day i looked at the electrical connector cap in the PCV kit and it hit me. . . the cherry bomb will override the stock fuel curve as well as the pcv, It took me a min to prove to myself that this was the case but this is the little test i did; With the CB plugged in I started the quad with the laptop connected to the module. Gave'r some gas and Kept an eye on the RPMs per throttle position and also keep an eye on the A/F ratio (Taking note on what they read vs the inputs on the table). They didnt match up so i simply unplugged the CB and started the same process without. I noticed a difference in curtain throttle positions and rpms when disconnected. The table wasnt matching the a/f ratio and RPMs in all the throttle positions while running with the CB. Only then did I realise what the only extra part left in the kit was for that i hadnt used (palm to forehead). Feeling dumb I unplugging the CB and put the cap in its place and the tables matched the little running stats on the right of the map. NOW, It sounded like some one said earlier on this thread that the cap is also a rev extention but I dont think that the cap is a Rev extender, only because when installed i was only able to redline at stock limit. Hope this can clear up some debate. I also have a few questions, (Is there a Rev extender that has no additional affect on the stock fuel curve other then the extention?) ALSO... I went hunting for a good starting point on a fuel map for my new build and i ran across some fuel maps with all negative numbers and some with all positive numbers. Its my understanding that The numbers on the map represent the A/R ratio on the table throughout the throttle positions. But if thats the case then HOW IN THE HELL, is it that someone can run all positive A/F with nearly the same setup as someone else with all Negative numbers. Im confused about this and hope someone can walk me through it. THANKS

A lil of this. A lil of that

Inside of dynojets rev extend plug is a resistor, that is what is "unlocking" suzukis race map. Inside of a yoshi crmb is the same thing. Me and my buddy are both running built ltr 450's with the cherry bomb still plugged in. I run a pciii he is running a pcv. We both make about 55 hp 40 lbs tq


As far as maps go, that will depend on the climate and the fuel they are running. I found you have to go allot richer if you want to run avgas vs pump fuel. Plus every motor is going to run slightly different, that's why I would highly recommend that you go get a tune made for your bike on a dyno. Anything else will just be "close"

thanks alot for clearing that up!! so basically the cap is just to like ground that out almost then its just all in the stock box and the pcv with the pcv being the override on the fuel map

Thats what im thinkin based on my experiences with it 2005450r. And i understand that with the different octains it would throw a bunch of different variables in the fuel mapping (drz 250) but Both the maps i looked at were bbks with similar mods and running 110 leaded. And i cant imagine that the elevation would have that drastic of an effect on a fuel injected bike would it? I could be wrong about the cb but if thats the case then why is it that my pcv is being overrun by it?

I know this is an old bread but nobody knows enough about these😡..also forgive because this is my first posting. First off I bought mine used years ago with PCV and ended up putting Stage 1 in/ex. Idiot put the shims in backwards. ANYWAY?.. I never really got to looking at everything until the other day and realized that t didn't have the Dyno rev x thing nor a cherry bomb connected but it did come with a brand new cherry bomb so I threw it in to see what would happen and after maybe 2 min of idling my temp light came on solid. I checked etc sensor blah blah blah.. idk what to do just take it back off? I live in ND and there isn't a tuning center anywhere near. I'd say don't use cherry bomb with pcv.. ps. Air box lid removed with yoshi full system
