Cold start issues on k series engine

hello everyone,

i am having a never fustrating issue with cold starting on my k24 engine, i can attached logs, maps etc if it help,

so once hot it will start better, bnut cold it can be a total nightmare, we have made the trigger wheel a 12-1 now as this seem a get around but it seem to be worst on the k24 than on the k20 i had before.

now, what i can see firstly is a bit of volt drop on cranking, but volts do recover, and see unexpected tooth errors on cranking/starting,

and also a back fire every now, what i noticed though is the ecu going into afterstart as rpm seems to spike, ive try rasing this but it wasnt happy starting once i rasied it to stop that.

it seems there is a common issue with k series triggers on the ecu master black, now would V3 software help in anyway?

if anyone wants to help i can send you all the logs and map, once it run it runs really nicely and no trigger errors etc.

thanks
