I use a crank trigger and retain the distributor purely to distribute the spark, the limiting factor is not the distributor but the engine. If you use high teens of advance for idle and the max you will put in is high 40's it only the phasing that needs to be changed.Philip Lochner wrote:In my mind it is hardly worth going EFI and then not do away with the dissy. The reason they are limited in ignition control is because they retain the dissy (which limits the amount of advance* one can have).
But one could still buy the Throttle body and then use any other ECU to control it which would then also offer distributorless and fully mapped ignition.
* My E-type cruises for miles on end with 50degs advance running at 17.5:1 AFR.
I have found the leanest I can go on cruise is 16.3 with about 45 degrees of advance. Any less fuel or more advance and you can feel it.
I have found fuel injection will give you about 15% inprovement in fuel consumption but with the Overdrive as well keeping the revs at about 2000 for cruising it can be as much as 50% driven crefully.
