Let me preface this post with this: I am not a very experienced car guy. I sort of inherited this car and am in the process of selling it but I want to be able to sell it knowing I'm not giving the next guy a problem. It really is a good car, just loud and because I didn't build the setup or dyno it myself there are too many unknown's for my level of knowledge. That being said.....
The following question pertains to a K24 series engine in a 2006 RSX type S which I did not build. This car drives great below 3500 rpm's. Above that I will experience random erratic injector duration on my Atoto/Hondata. As the happens, the car is very 'jerky' and the injector duration guage is going nuts. This has only caused a po300 type code once while going interstate speed. The car idles smooth and like I said drives great as long as I keep the rpm's below 3500.
I've changed the turbo, all plugs, ignition coils and the injectors have a normal rhythmic clicking sound in idle and when in neutral and gas applied to the higher rpm.
My question is simply this; If this were your car what would be your next step in trying to pinpoint the problem?
Thank you for any input.
Erratic injector duration above 3500 rpm
Re: Erratic injector duration above 3500 rpm
Have you tried following the factory service manual troubleshooting steps for the error you are getting?
If you do and it says it an ECU issue, then it is probably a tuning issue that a tuner would need to look at.
