hi all
i have recently finished a ca18det engine and i need a starting point for tuning. here are the mods: stock bottom, gt2876 garrett turbo, 650cc injectors, z32 maf, 255 walbro pump,colder intake, 3" single exhaust, big front ic...and recently bought nistune type 1 board and software
if there is somebody with and appropiate setup and wants to share experince for a starting point like k values,injector latency,fuel maps,timing maps etc i would appreciate the help...
the closest rolling dyno is 200miles away and i am trying to get the best ecu tuning and just finishing on the dyno. i also have a plx afr on the car so therotically i can get pretty close to good tuning with your help.
thanks for reading my post and for helping me if you can

first of all try just a standard rom file with the modifications for the AFM of Z32 and the 650cc dont touch at the latency
then fill all of the map with 14.7 AFR
then take a ride and test you have the correct AFR on your PLX, if it is not correct when driving, modify the K value, If correct , just stop and take a look at the AFR at IDLE, if not correct, adjust it with the lattency value.
then retry driving, you might have all good, if not modify K when driving, then lattency when IDLE.
you should have the correct setup now.
after that you will never touch this anymore, just try the other parts of nistune...
