  1. got my PCV for my 01 today, can't wait to get it installed. Hopefully I'll get it in this weekend. Did not get the autotune yet. Only one tuning farkle at a time right now.
  2. Yeah I was thinking about something like this 4 into 1 manifold I just wasn't sure of the sizes, so I was asking what others have used. I wish that someone had a cut away of the throttle bodies that could show where all air passages enter into the intake tract.
  3. Okay I'm following that. My question was were did you find the 4 into 1 "T"?? Auto parts store or somewhere else??
  4. Well I see you are putting the bung in the tail end of the collector. I'm just going to swap out one of my stock o2's for now. Where did you find the 4 into 1 for the vacuum switch? I already have the switch from Coderighter, but was waiting on the PC V and autotune to arrive before installing it. I'm sitting here waiting for my pcv to arrive, and I should have already had the autotune in hand (damm ebay copyright policies). My underseat area is going to be a solid mass of equipment by the time I get all the stuff installed.
  5. Yup that's the plain truth of it. Add in that any pump has an efficiency range that is speed dependent and the mechanical pump suddenly doesn't work so well. Its too slow and inefficient at idle, when you need good flow. And it's too fast at High rpm's causing more inefficiency due to cavitation. Not to mention the impeller on the stock pump is about as cheap as anyone can make one. A properly fitted electric cooling pump is a great thing. It not a 'free Lunch' thing so much as 'healthy lunch' kind of thing.
  6. Thanks for the table. I'll be dumping that in as soon as I get the PC V. How did you make out on the vacuum switches? I'm going to need one for switching the autotune on and off as well as one for possibly switching the output of this project on and off. I might try to re-use the pair solenoid, driving by the switch to control the flow. If you have found a use for the extra switches, can I get the source so that I can order several for myself. I have a feeling I'll need several more of them in short order.
  7. Then yeah I'd appreciate the sensor tables. Particularly since on the last ride, I did not wait to let the bike warm up and running in 45 deg air it took for ever to get warm. And even with my nose, I was pretty sure it smelled rich to me until I really got it warmed up after a fuel stop (also got the worst mileage of the 500 mile trip).
  8. Not sure how much I can help you other than tell you to get right back to riding. When I went down in august of 2008, I did not have the luxury of taking my time. My bike was my way of getting to work everyday. So I was back on a bike in about a week (with my still cracked ribs). And it was not a perfect machine either, It was my three week old RC51. I bought it as a theft recovery and it had lots of little problems. The big ones were a slipping clutch, a busted throttle tube and an Iron hard shinko rear tire (in the wrong size of course). Maybe having to focus on making it all work as best I could, while I got parts in was how I got past the worries and fears.
  9. yeah I'd be interested in getting one, maybe two, but at least one. The first thought is duplicate your setup with one my 5th gen to shut off the autotune function on deceleration. The second I'll use if the Pair Solenoid turns out to not run at lower engine temps as I need a way to shut off vapor flow from device on deceleration. I've had block off plates on my VFR since before Toro was done with the prototyping of the toro-charger. I just capped the ports of the solenoid and the airbox and left it plugged in. But if it really only opens on deceleration, then I'd rather use it to control the vapor from a project device. If not I can always find a spot for another vacuum switch, a relay and another small ported solenoid. Will your tables work with a set of 5th gen maps? If not I'll just do it myself, it doesn't sound impossible. I'm really hoping I can get some positive results with my project before I have to install the PC-V, autotune, the vacuum switch and more tuning stuff. But we will see shortly.
  10. Hey can you give us the source for the vacuum switch? I may need this for more than just a way to switch off the Auto-tune on a project I'm working on. Also can you confirm for me, if the pair solenoid is activated or deactivated on deceleration? For some reason I thought it was deactivated, but someone else here said its activated on decel. Lastly, you said the temperature sensor has to be calibrated, which is the first I've heard about this. Is it a difficult process, can you describe the procedure? At this point I think the PC5 + autotune and a vacuum switch is going to about half of the hardware costs on this project. At least I'm hoping so. hoping to find some simple answers to some complex questions.
  11. I would contact somebody like JE pistons and see if they have any big bore pistons in their database. They have lot's of custom pistons that are not listed in online or paper catalogs. The 870cc slugs for the vfr800 are one example. Or they might even be able to tell you if another piston from a different application will fit (like say a cbr900 oversize piston). You just have to some phone work and ask questions.
  12. Okay I get it. The issue is more with the PC V's programming or the Autotunes programming. Are you planning on going to Gear by Gear mapping as it still sounds like it would help with this issue. Also is there a load offset map that would allow you to offset the rpm ranges across the cells when you us gear by gear maps? Then the 6th gear maps could have more resolution at the lower load ranges (say every 5% instead of 10%, until you pass 30%). Still Gear by gear would be the best way to handle this, since as you pointed out low load conditions vary the most as you go up and down through the gears. I know that bikes don't have Air flow meters, but not all car systems do either. A lot of race systems are 'speed density' and work from "known" airflow calculations. I used them on turbo motors as high boost could exceed the metering capabilities of a small mass air and a large one would not have enough sensitivity at low flow.
  13. But I thought the point of this whole exercise was to give the VFR the Ultimate alternate front end. I thought the challenge was to build up something special around a mighty VFR motor, not just slap something on an I2/3/4/5/6 whatever motor. I know a custom bike builder in the area, that told me the following. "Vtwins are easy to make choppers out of their a dime a dozen, Inline fours are next since once you do one the next one is the same, but the most challenging bike to customize is a V4. Do one of them right and you have something really special" I personally feel that he is more than right.
  14. That is an important and interesting bit of info. Kudos on the solution to the issue, but it makes me wonder about a couple of things. Why isn't the canister purged at high vacuum levels?? I wonder, does the ecm not see zero load when you blip the throttle to match revs?? I though this new ecm strategy used calculated load based on TPS, rpm, gear and Delta Rpm direction.. If so I would try setting the adjustments in the table at zero loads to very lean all the away along the row or column. Then it would quickly want to trim back and not get the autotune module confused. Also is there any "throttle position latency" factor, if so cut it down until it starts to be touchy at steady cruise. Like the old dashpot dampers on carbureted engines there is a function built into the EFI to prevent it from shutting off to quickly or too long to prevent stalling. The PCV may or may not be able to alter that. If it can I'd say have at it. One last question, is there anyway to adjust the O2 sensors delay for less hysteresis in the autotune module? I have some experience with some of these factors on automotive systems and I'm sure that they exist in MC tuning.
  15. Cool, that was the bit I was missing. Thanks Pete
  16. Okay but you have an 6th gen??? Am I missing something?
  17. Oh yeah, like everyone else has said, Your okay (or soon will be), that is what matters. The bike can be rebuilt or replaced, but you cannot. Get well, then get back to fixing it up. But do the brake hoses right this time okay???
  18. Hey, just a question. Has anyone crash tested these sliders on a 5th gen yet?? That has been what has been stopping me from getting sliders for my 01. Most of the ones that I saw before, caused more damaged to the bike than just rashing the plastics. Sorry, I'd just like to see some post crash pictures before I'd buy these.
  19. I have been getting more requests for the RC now that the site has launched. It's certainly a possibility, but I do have other bikes lined up to receive kits first. If there's enough demand I'll make a kit for any bike, but without feedback it's very hard to gauge real interest. It should work fine with the stock exhaust, but just realize that with the supercharger, the more exhaust flow the better, which is why I'm kicking around the idea of making a full system with larger diameter tubing. There's certainly power to be gained by opening up the exhaust. As it stands, catless '98-'99 headers are the best flowing pipes found on any VFR. I'll find out how much power is lost from the cat once I bolt a kit onto a '00-'01. Again, a slip-on is not needed, but will certainly bump up the power output -- if you're able to gain an extra 5hp or so on a naturally aspirated motor, you can imagine what it will do with the supercharger. This is also why I don't quote actual hp increases, as bikes and dynos vary too much from one another to accurately nail down a number. However, a percentage increase I can quote, as boost is boost, and affects your engine's efficiency (changing the exhaust will only help to increase that efficiency). Okay so which one of my bikes do you want me to drop off first??? Guinea pig bikes get an added discount don't they Dan??
  20. All right, That looks great. Now I just have to sell a bunch of stuff, each cans of tuna for a few months and decide which kidney I really don't need. Seriously, I'm there Dan and you know it. I was hooked just from the day I was out chasing after you. I just have to pull the $ together.
