Coil on Plug

There's individual coils on my setup, no cranks sensor needed, we took the signal off the exhaust cam/rotor arm.

It is basicly the same to use the cam or crank to calculate the degrees for the ignition. The principals are the same .Vr or hall sensor and a marked (somehow)
wheel with an interuption . (toothed,hall type,or whatever). Apart from that is the ecu you got the limit..should suport this system.
For example 4e use two vr coils inside the dizzy and two wheels. One with 24 tooths and an extra reseting point for the other vr sensor.
You have use both of them vr sensors or you have fille down one tooth of the 24 wheel and run one vr sensor? What ecu you got?
Also individiual coils are different from cop .Cop is what most of the bikes use for ages. Same idea tho but different visualy.

Same as above. individual coils setup will be implemented when wiring in my standalone ecu, wont have time to do this till late january (Uni commitments wont allow).
You can get 300whp from the stock ignition, as stated in this thread. but it wont be reliable, hence the change to individual coils. A single coil that was ment to ignite all 4 combustion mixtures for a stock 133hp engine 11-20 odd years ago, wont be able to hold a strong spark at 2bar boost pressure between 4,500rpm (whenever high boost kicks in) to 7,200rpm (redline) for 10,000miles a year. It just isnt logically viable, there will be fails. plus having individual coils on a standalone will allow your igniton to be more tunable.

in america, there was 5efe in california and they used a crank sensor built on the oil pump, and they also had semi direct ignition coils, (semi-direct is where the coil sits directly on 1 plug, and has a lead going to the plug next to it)

U don't need a crank sensor i've wired and ran coil on plug and full sequentail injection using the stock triggers

Yeah u can use super bike coils , evo coils , yaris coils tho there not the best if it was me I would use 4 Ing 1a coils if u want a big big spark but u would need to use leads but so what it's not big deal aem make good coils for mountn on top of the plug too

the distributor VR signals are both cam and crank signals , a standalone ecu will be able to use this for COP and sequential injection ,
VR signals are more prone to timing scatter at higher rpm , so to run say 8500 to 9000 rpm i would use the crank signal on the oil pump (hall effect)
