calibration for swapped injectors

Post by freydaddy »

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?

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.

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?

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.

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.

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.
