Lampredi 8V twin-cam - Omex management?
Discussion
I have a Westfield with a 2-litre 8 valve Lampredi twin-cam lump. Brief spec:
Gas flowed 'Volumex' head with 43.5/36mm valves
Bogg Brothers R1 Carb conversion
Piper BP300 high lift 290deg cams
New High compression 84.4mm domed pistons giving 11:1CR
Guy Croft uprated head gasket
Guy Croft 12:9 race head bolts
Guy Croft oil pump
New std size big ends
Alloy velocity stacks
Pipercross air filter
Competition adjustable vernier pulleys
Uprated external oil cooler
Gratuitous pics:
Anyway, it's currently laid up while I sort out a new dash, and it's due to make a visit to Northampton Motorsport soon to have the new dash setup wired and fitted. I'm also considering going for an Omex 200 ignition ECU - there's currently no management system at all (no rev limiter!) and I think it would help with a bit of a flat spot I'm getting as it comes on cam as well as the general driveability of the car. The car has spent a lot of time on the rollers trying to tune the existing setup and I don't think it can be improved on without looking at some sort of management.
I'm not hugely experienced in a) aftermarket management or b) shouty Italian lumps - can anyone shed some light on whether this is a good idea or not? It has been suggested that I should look at EFI at the same time, but I don't want to lose the character of the engine and I'm not interested in chasing numbers - plus it's a lot more money which I don't really want to spend.
