RE: HTEV & Servo
I flipped mine and didn't noticea difference seat of the pants.Nice work on the elim, I thought about making one but don't have the capability to cut the flanges withoutjust plasma and grinding. Not so nice. Have yet to try playing with the pc3. Just not real comfy with it yet and playing around with maps. Good news too, I never threw a code. I would guess a hundred or so miles on it.

RE: HTEV & Servo
My bike came with a full Erion system and I've never seen a light/error code from the ECU. Bike runs silky smooth due to the custom mapped PCIII down low and up high. Does seem to get a "jolt" of power around 3k, but I'm used to that now. So I don't think there's any loss in low end if you make up for it with a good PCIII map.
My question tho is why don't I see the error code/light since the HTEV is obviously gone? If what you guys are saying is correct, then removing the servo should throw a code. I don't think the PO would have left the servo connected and just ziptied it somewhere to the bike. I don't know if there's some device that comes with the full exhaust kits to trick the ECU, but somehow it all just works.
Just wondering.

RE: HTEV & Servo
Your servo motor is still there if it's not throwing a code. Removing the HTEV and adding a PC has nothing to do with whether it will throw a code if the servo is still plugged in. Simply look to see if it's there or not. On your knees, look at your left footpeg and then look up under the tank, it hides right behind the left frame spar. There will be a 6 pin connector harness coming out it and that goes to the ECU. If it's plugged in, that is why you still are good with the code light.

+1 and you may still have the flapper hooked up so there will be one cable still attached. The flapper may be the jolt at 3k.
Metalhedd how about sending me your map if you have it downloaded? Or have you compared it to the maps online for a full Erion? I'm still trying to get fimiliar with the whole pc3 and mapping before I start playing.

RE: HTEV & Servo
Here is the latest update on the good R&D that Sam is doing: We are currently doing some A/B comparisons to see how alternative servomotors differ in operation and are having good success so far. Stay tuned to this forum and I will keep you updated on progress and when Sam will be ready to market a servo substitute.

RE: HTEV & Servo
Ok guys....here is the latest on the servo R & D that Sam and I have been doing. After many rounds of measuring voltages at different RPM's and trying different circuits, it appears that Sam has finally hit paydirt !
I am currently running his 1st prototype servo replacement in my tail piece with an extension pig tail (for ease of accessibility) and after a couple days of throwing it every variable I could think of (load, rpm, gear, etc).....the MIL light has remained extinguished, the bike runs purrrrfect and there are no glitches to be seen. Bear in mind, this is with my exhaust valve locked wide open and the flapper valve in the air box removed.
If you want to stay in the loop and buy one from Sam when he goes into production, email me directly and I will get you in touch with him. This is for all guys who have either put on a full exhaust and have the MIL light, their MIL light is on because the servo is toast or simply want to open up the exhaust flow. The stock servo weighs about 1-1.5 lbs and this replacement is about 4 ounces with NO moving parts.
KidCr3nshaw, I know you are waiting on this...so hit me up via email. Webmasters, this may be work pinning for all to see, because it applies to all 900rr's, 929rr's, 954rr's as well as the 600rr and 1000rr
