Hoping someone got an idea for me. Car is heavy on fuel. R100 to do 40kms driving at 100kph no boost.
No smoke runs smooth. Car Stock expect walbro pump
What i have done / Checked:
ECU no error codes.
Replaced injectors which sorted some issues out.
New cam belt and tensioners, Belt lined up to marks
New Water pump
Checked for air leaks (could be one)
Cleaned AFM
Checked grounding
Timing 15deg
Compression even on all 4 and in spec
Bov?
Have you any idea what the afr's look like?
Is the knock sensor connected?

None. Stock T25 boosting 0.6 / 0.7 bar. As stock
you dont know anyone with a spare ecu that you can just test and see. the ecu might be seeing different readings from your sensors beacause its broken. and have you changed the engine coolant temp sensor?
you gonna have to check wiring from ecu to the main things that are gonna affect fuel consumption MAF engine coolant temp sensor ect. if a cable is not dead short it will change the value that the ecu sees
Pull the CA out, Fit a SR/RB , have it Tuned with Decent Management................... Fuel Sorted! 🙂

Skyline's RB also has fuel problem and its going to get worse with GT2860R's -7
There seems to be one common problem in this whole equation. 🙂
Any luck rat
