Wideband sensor, Bosch lsu 4.9
Wideband module, tinywb. Problem might be too much power consumption, probably need to get 150w alternator
Fuel pressure regulator 2.5bar with map reference
Small external fuel pump is hard to find... But one with 12v, 1.5a, 3bar would Flow 25l/h and I only need about 8l/h.
It would mean pwm with vvt output, mosfet rfp 30n06le, 10k ohm resistor and 1n4001 diode. Was thinking 40% duty cycle at 100% tps and rpm.
But I could not find vvt settings on tunerstudio...
