Can any of you good folks help ?

I'm putting a 5.5L LS6 engine from a Pontiac Daytona Sports Prototype into my Lotus Esprit silhouette race car here in the UK and am struggling for an ECU .....

There is a firm here in the UK that make good value for money ECUs, but they are not sure their latest models will work with GEN 3 tooth patterns, but if I can get a crank oscilloscope plot they may be able to programm it to work.

I am running a 24 tooth trigger wheel.....can anyone provide ?

Cheers Simon
