A 360 degree twin is simpler then others designs since you can use a wasted spark system. BTW: You can get electronic ignition for Triumphs and Nortons. Do you have a WWW home page?

A few weeks ago, the local public access channel had a "learn-at-home" mechanics course that was being broadcast from a couple of tech schools down south. Anyway, they were working on the crank sensor on a 3.8 buick when they went into a discussion on this very subject. Seems a lot of servicemen were forgetting to put the shielding back on the crank/cam sense wires, and it was causing random intermittent problems. The instructor then fired the car up without the shielding, and showed the crank waveform on the scope. Full of spikes! The engine was also running like crap. Shield back on, everything was fine. A lot of the problems had to do with proximity to the coil packs. You could probably get by with some creative routing, until you hit some outside source of EMI. I can just see someone's ignition system going haywire in an airport parking lot. :) Dig sdbartho@hwking.cca.rockwell.com From Diy_Efi-Owner Wed Jun 1 19:47:10 1994 Received: by coulomb.eng.ohio-state.edu (920330.SGI/920502.SGI) id AA27437; Wed, 1 Jun 94 19:47:10 GMT Received: from hwking.cca.rockwell.com by coulomb.eng.ohio-state.edu via SMTP (920330.SGI/920502.SGI) for /usr/local/mail/majordomo/wrapper resend -p bulk -M 10000 -l Diy_Efi -f Diy_Efi-Owner -h coulomb.eng.ohio-state.edu -s -r DIY_EFI diy_efi-outgoing id AA27431; Wed, 1 Jun 94 15:47:07 -0400 Received: by hwking.cca.rockwell.com (5.65/DEC-Ultrix/4.3) id AA00447; Wed, 1 Jun 1994 14:47:03 -0500 Received: by ohura.cca.rockwell.com (5.65/DEC-Ultrix/4.3) id AA02147; Wed, 1 Jun 1994 14:46:16 -0500 Message-Id: <9406011946.AA02147@ohura.cca.rockwell.com> To: DIY_EFI Subject: Boost detection Date: Wed, 01 Jun 94 14:46:15 -0500 From: sdbartho@cca.rockwell.com X-Mts: smtp Sender: Diy_Efi-Owner Precedence: bulk Reply-To: DIY_EFI I need a method to detect a certain level of boost on a '91 GMC Syclone. (P4 ECM, Turbo 4.3L) I'm trying to design a booster (fuel)pump system that will provide added volume when the boost is greater than 14 psi. What I'm thinking so far is to use the MAP sensor to trigger a FET/relay to turn on the second pump, but I'm not really sure I know what levels to expect out of the MAP. Anyone have any pump recommendations? I need pump capable of at least 80 psi, and I would prefer a high volume unit as well. Also, anybody got any good ideas on how to monitor O2 output at the track? OTC's are pretty expensive, but the only other method I can think of is a DMM in max mode.(would get a rich indication anyway) Stoich on GM sensors is around .4-.45 volts, correct?
