2jz gte fuel map problem

[chase350z]

2jz gte vvti with mspnp pro with 1700cc injectors
with the fuel map all the values are way to high at idle the fuel load is at 120

Have you flowed the injectors, all of them, to determine dead-time and flow? With a req_fuel of 2 msec those values need to be very accurate, and you will probably have to create "small pulse-width" curves to use.

I have not done ether.

Is there a tutorial on how to do that?

Thanks chase

What is your map reading with key on, engine off? That would indicate you are making boost at idle, so I'm wondering if the map sensor is calibrated and reading correctly as well.

The map sensor calibration is on my mind too. Fuel load percent is tied to the map reading, so your idling at 120kpa! Check it's calibration for sure

Just as a note, my 2j had some 1120's almost turned up to 1300's and my fuel map looked normal. With it up to 300kpa I barely touch on numbers over 100 ve

I think this is the fuel map that steve and I were talking about yesterday and you had deadtime questions too
