I have few questions about setting up the ignition system for the 1jz.
the 1jz has three sensors,
2 camshaft angle sensors
1 crankshaft angle sensors
It also uses Coil on Plug system with an separate igniter configured for wasted spark.
What would the best setup look like?
ditch the external igniter and get the 6+2 VEMS configuration ?
MembersPage/PhatBob I guess it depends what you want, if you're going to re-wire the whole engine loom then dump the igniters and let VEMS control things. If you want to keep things looking stock then theres no point in replacing something that works fine.
Personally I'd run the coils direct from the VEMS but get the Option 8 as you'll have a couple of spare high current drives that might come in handy.
Do you have any more details on the camshaft sensors? I guess the crankshaft one is the 12 tooth afair?
