Tuning help for my sr20det

hi everyone,
i am florian from france, sorry if my english is not perfect.
in my previous topic i find which ROM add to my new used ecu with nistune.
my config:
forged piston cp 8.5:1 / forged rod / TOMEI ARMS SR M8270 ( actual 0.8bars because my last ecu have a stage 1 horsman ) / Big FMIC / 255lh walbro / boost controler / 3" exhaust
my futur config:
bigger injector ev14 approx 1000cc for e85 / turbo to 1.2 bars / z32 MAF / cd009 6 gearbox
But first i just want to make the car run like before with my previous ecu( horsman stage 1) and beggin slowly the tuning.
so i have to :
Check IGN on nistune and compare with strombo light, check CAS, clean maf, check spark plug
-1 burn the 82F0F ROM
- because i do not change my injector and MAF, i do not touch the K constant or TIM in my case because i have an FP1
-Check if my FT is ok at idle and cruise 2000trs 4 gear + ( need to do this if i do not change injector and maf ?)
-Adjust the fuel map in low boost but on all range of RPM (maintain 14.7 in the blue area)(trace afr againt fuel map ?) do i have to correct it by using a % change in blue area ?
-Adjust the fuel map in hight boost in hight load area, check the AFR (11.7 :1 AFR) by lowering the value in % only in the hight area ? how many to begin ?
-Make a knock copy to ajuste knock fuel map
-up the turbo to 0.9-1-1.1-1.2 ( contrôle if its knock and adjust the timing map if necessery
-Adjust timing map until a knock is detected by nistune there is another methode ? i am not sure to understand how to ajuste it correctly ? same as fuel map, by area ?
not shure what the best option to check afr against fuel map and knock agaist timin map by tracer or hightlight ?
because i have a differente turbo who is beager and blow later than the original how i have to react for this ?
tank you for all
