Bigger Injectors How do I Remap?
Buying bigger injectors for my bike,how do you go about getting the fuel map close enough to let the autotune take over?
Where do i set the fuel regulator after the intial 43 psi?
I am going from the stock 440cc 06 injectors to 700cc injectors(turbo bike at 7psi)

well, maybe schnitz or whomever is selling them has a baseline map for those injectors and boost.
Otherwise I would make some volumetric calculations and build a theoretical map
example a 700 cc injector flows 159 % of what a 440 flows.
[700 divided by 440 = 1.59]
divide all cells in your 440 cc map by 1.6 and that should be a pretty close baseline.
You might want to err on the safe side and divide by1.7
that will add in an additional 6% errror factor on the rich side.
I haven't done this on turbo yet, but its the same idea as I did for my nitrous maps.
I would keep your static pressure at 43 psi, and wouldn't ever see a need to change that unless you run out of injector.
Of course I would start off limiting boost to zero, with the wastegate, ride it and tune for that ,
then go out again limiting it to 1 psi, and remap after running that and collecting enough data, then 2psi same thing
go slow and easy data logging and tuning for each psi , 1 psi at a time.
****remember, this is very important ****
Turbo is very sensitive to atmosheric density, so down the road you'll want a cold weather, and hot weather map, maybe more
Sounds like things are coming along for you!.
Congrats, I am happy for you  .... maybe I should have kept that kit .. haha

hey stu64 huw did those injectors work out
can you tell me how kong they are and did they fit w/a billet fuel rail
and why did you go with the 700cc and not the 630cc the 630s were 60lb maybe a little more streetable
. how mutch boost are you going to run i got 20lbs out my stock ones no problem
hey if you didnt make a map yet brian from Winn racing can make you one he will be at the last 2ws
