dlaing Posted February 13, 2008 Share Posted February 13, 2008 Yeah that is the gist of it. I think one of the Right Things you could do with this is what Cliff does. Treat anything above 50°C as "we do not need a choke". That sounds like a good idea to me! The potentiometer solution, while fool-proof, is down right ugly. But it has the potential to be an onboard optimizer. For example if you want to flog it to keep up with your buddy on the Hayabusa, run it rich. Same if you are stuck in a traffic jam. And if you are droning down the highway for many miles, leaning it out could improve fuel efficiency. Caught in a rain storm, set it to lean. All done within sensible limitations, of course.

When droning you will use the middle/left parts, which should be tuned for economy. A good map has practically no downsides in this aspect so you could just make it worse with that potentiometer!

Many of the PCIII maps are simply mapped to one or two designated lambdas. When it rains the sensor will tell the map to grossly enrichen. In a traffic jam, the sensor just tells it to run leaner Altitude is under-compensated for at higher altitudes. Cold temperatures seem to be over-compensated for.(which is the primary point of this side-tracked discussion) Link to comment Share on other sites More sharing options...

But I'll be happy to discuss other sensor concepts in a brand new thread. I just re-read this one wondering how we ended up having this conversation in this thread and one thing I noticed is our latest ideas are not fixing our initial concerns cheers Link to comment Share on other sites More sharing options...

polebridge Posted February 13, 2008 Share Posted February 13, 2008 I contacted MPH Cycles to find out if they stocked the Roper plate. According to Todd Haven they normally have them but are currently out of stock waiting for Pete's next run. Any idea on when you might be sending MPH some new stock Pete?

dlaing Posted February 13, 2008 Share Posted February 13, 2008 Just to get back to the original subject I had a post from Todd at MPH saying that there were people asking about availability of the plates. Well I'll be posting 10 of them off on Monday so they should be there in about a week but until then get off the cripple's case or he'll insert his prosthesis up your date Pete Link to comment Share on other sites More sharing options...

dlaing Posted February 25, 2008 Share Posted February 25, 2008 Here is the engine temperature compensation map And getting back to the highjacked topic, anyone buy a MotoModa sheet lately? Link to comment Share on other sites More sharing options...
pete roper Posted February 25, 2008 Share Posted February 25, 2008 Here is the engine temperature compensation map And getting back to the highjacked topic, anyone buy a MotoModa sheet lately? I sent another 10 to Todd a couple of weeks back and most of the rest of the last batch have gone. Chris Craft, who posts here as RossoRC or some such ordered one a few months ago and although my records say it was sent it didn't arrive so I've sent another one out which I hope will arrive more promptly! Other than that I've sold several to Europe and a couple more here in Oz. As I've said before I'm sure if anybody has ANY problems, with either non arrival or installation I want them to pester me, publicly if they wish!

Pete Just received mine in the mail from the guys at MPH. They are very prompt and I was suprised at how quickly it arrived. I hope to get it installed soon. Thanks again Pete.

polebridge Posted March 5, 2008 Share Posted March 5, 2008 One quick question before I start the install. What is the proper torque on the upper sump bolts? Thanks Link to comment Share on other sites More sharing options...
