Ignition management

[ADL Mark]

Chatting to my mate's Dad earlier, he's building a Fisher Fury with a 4A-GE engine in it. He's decided to go for a pair of twin 40 Weber carbs on it instead of fuel injection (can't wait to hear it) but is looking for a system to control the ignition, and get rid of the dizzy.

He's been recommended a couple, but wondered if anybody had any experience of things like this and could recommend anything, especially the likes of Ryan who do this day in day out? So far people have mentioned things like Omex and GEMS I think it is, that do just ignition control?

Oooh, 4-AGE, I run one in my Zeus race car. That's on twin 48 DCOE and Electomotive ignition "management". It's ultra crude, with only about 6 load sites, but works OK'ish. It was fitted in the US, which is the marketplace the car was built for. I'd like it on a basic MBE ignition only ECU really, like the Opel 4 pot in the other car. That's on 48 DCOE's.too. The MBE unit is a LOT more sophisticated. There are loads of used MBE boxes around as they were standard gear on Supersports cars and Formula Vauxhall single seaters. You should get one with a basic engine loom for about 100 quid.

Now that sounds like the kind of thing he's looking for, enough functionality without a stupid price..

He's been speaking to Raw about getting an alloy crank pulley that's made up with a sensor pickup in it, and from what I understand the ignition control systems they've recommended use a sensor on a bracket next to this to work from. I take it the MBE is similar to this?

He's taking the engine apart and giving it a good workover before it goes in the car, getting the crank and all journals checked over and new rings in at the very least. New valve stem oil seals etc. and he'll do some headwork on it (a hobby of his and he's pretty good at doing a bit of port matching and gas flowing) just to clean up the casting.

Sounds like with a small amount of work on the engine and the carbs on it, it should be pushing out 135-140ish bhp which should be interesting in a car just over 500Kg :)
