calibration for swapped injectors
calibration for swapped injectors
I am having a difficult time trying to get my D16 Honda engine going. I swapped in some new 550 cc injectors (high impedence (13 ohm) in place of the factory 240 cc injectors (12 ohm). I have the s300. I went to the fuel trim tab and changed the injector sizes. Is there something else I need to do?
Re: calibration for swapped injectors
Does it start with stock injectors?
Re: calibration for swapped injectors
yes it does. I got fed up and replaced the old injectors back just to see if it was something else.
but im not giving up, i need the bigger injectors for the turbo setup.

Post the calibration and a datalog trying to start the car
Re: calibration for swapped injectors
just an update, i had a bad ect sensor. now replaced.
maybe the whole problem all along.
i will keep you posted when i try to swap the injectors. again.
here is a question...If I run 550 cc injectors without the turbo (na), could i set it for 240 cc with no problems?

Re: calibration for swapped injectors
update...Got the 550 cc injectors in. ready to finally drive this to the tuner.
starts right up when its cold, 1500 rpms.warms up after about 3-4 minutes, then idles roughly at 850. Then it dies when it is warmed up. Fuel vapors in the garage will burn your eyes. Wideband reads 19.
Next I set the injectors value to 240 cc, it reads around 10.
when I set the value to 440, it is pretty close to target (15).
I need somebody that knows this s300 software to get it where I can drive it 25 miles to the tuner.
I know with time I will understand it, any help please.

Re: calibration for swapped injectors
Have you discussed this with your tuner? They should be able to look at a datalog and help you get a better basemap built. If not, then you will problby have to tow the car to the tuner to be safe.
Re: calibration for swapped injectors
sounds like you arent running the right fuel pressure.
Re: calibration for swapped injectors
update: everything is close to good on the calibrations. The car idles (950-1000). Lambda reads around 14.7. after it is warmed up then shut off, it will not start until it sits for about 10 minutes. I recorded a datalog for about 3:37 minutes. But I really dont know what im looking at on the graphs. Almost like it is getting too much fuel.

Re: calibration for swapped injectors
any intelligent input on this datalog?
Re: calibration for swapped injectors
its been a month since I posted the datalog.
does anyone see anything wrong with the calibrations/settings?

Re: calibration for swapped injectors
Lambda is at 12.4:1
injectors are 2.22 ms
wishing some one could show me how to lean it out a little
