I have seen the twin spark dizzies. Straight forward.
Then there are the crank fire twin pack setups. ok. what else can be used? Piggyback systems? (picture is for entertainment purposes only. this is not my motor) Attached image(s) |

As far as crank fire. There is NO WAY a dizzy can be as accurate as a timing wheel on the crank.
WE have beat this question to death on other forums. With back to back dyno tests from Lance Nist. (Lance has enough patents on automotive ignitions and ecu's to make your head spin) The wheel works best. There are harmonics and dizzy gear lash issues that won't allow a dizzy to be as accurate as a wheel. If the engine is out of the car such as in Randals case. It is is no big deal to install a wheel on the crank. And install a sensor on the block. Most of the MegaSquirt guys do this. I THINK Jake has done this for a SDS installs. (Jake, chime in here please) It's really not a big deal to install one. If the engine is out of the car. Conversely, If the engine is in the car. And you don't need/want MAXIMUM benefit of a trick programmable ignition. Using the dizzy to trigger the ignition.. WORKS. And works pretty well. Kinda depends on your end result, dollars, willingness to get the maximum benefit of the system. Rather than writing a dissertation on this. I will post a link of a guy that did the Wheel installation on a water cooled 4 cylinder engine. He went from Ford EDIS coil pack to COP. This guy kinda reminds me of Trekkor. Make do with what you have. Fun little article...... BMW 2002 M/S COP install. There are already type IV crank wheel setups for sale from vendors. IMHO... That is the best way to go if the engine is out of the car. And I agree Brando... This is a great thread. OH..... Randal... I won't second guess Neil Harvey. (very often) C |
