Issues
- primary trigger errors in higher RPM (7200+)
- idle quality. Without MAP it's pretty hard to keep good idle. -
- suffered from "VEMS disconnected" while cranking, connecting VEMS, testing coil -(fixed, rewired loom, better grounds)
Summary
Running pretty much OK. WOT is perfect, commuting is OK, idleing is not so good.
Great fun, very satisfied with how VEMS is doing the job.
With further improvement, i'm sure this will work almost perfect.
