you got it. post up a bin file and a full boost log when you are done. post your mod list.

you are shooting for 14.7 at all rpms when setting your injectors so you have to take the fuel map out of the equation by setting them to zero. This is only while testing. then you have to put the map back to normal or you will blow up your car.It sound like you are understanding the process. by the...

your car is still accessing the fuel table which is throwing off your settings. So you need to turn them all to 0. you will find that latency effects the hole power band. The k value is not an exact science and will be different from car to car as will latency. It is ok if it is not half the number ...

The timing map in gts-t log looks just like the timing map on my eclipse with pump gas. how ever I do not know if it is good for your engin.

try unpluging your o2 sensors and tell me what a/f dose at idle ,2000,4000 with the car out of gear.

Yes I think it would be a good Idea to pull timing up top. Z1 suggests 3-5 deg's. pulling the timing will help hold off knock as long as you have good a/f mix. I would look in to how to set your injectors up right because it can cause you to run lean at full throttle. The reson your car seams to be ...

you still are useing the stock latency with 740 injectors. It should be more in the high 800 to 1000 I think. I know not every car is the same but there is no way that 740s take the same time to open as 370s unless you have changed the fuel pressure or somthing. when you disable the o2s and clear th...

what boost pressure is this at. z1 recomends you pull some timing out with boost over 12 psi.

I think I was haveing a fuel pressure problem. Fixed the fuel problem and then every thing lined up great. Matt how many people are useing nistune on a 300zxtt? Here is a file of where I ended up. I am useing deatschworks 780cc injectors,single pop charger.

Hey Im new to nistune and have been running it in my car for a week. I was wondering if any one here is useing 780 injectors on a zxtt and would be willing to let me see there image file. I am haveing some trouble getting a good base tune. I have a wideband o2 sensor but do not have it set to work w...
