I always been curious about what people mean when they send it over to "Honda"They want me to email the receipt once I get it. My service adviser was kind enough to show me all the snapshots and their data logs. Everything came back normal for the injectors and they had first assumed it was either the block or a software problem. They sent everything over to Honda and Honda advised to swap the injectors even though they looked normal. Interesting how they knew the problem as if this had happened before. I'll keep an eye out on things and hope it was a faulty part only.

Do they send it over the details to Honda in Japan and then a person who worked on making the engine takes a look at whats wrong?
This more goes to show that Mechanics at many dealerships are considered low duty nowadays. Gone are the days where a mechanic can build, spec, blue print, time carbs, and most importantly troubleshoot an issue with readily available technician books. Low duty meaning parts swappers. There's usually only 1 guy in a dealership that can do all but doesn't bother because it doesn't pay well when you're working against the black book.Not sure if it's Japan but I read the notes and they pretty much called a "tech support" line and got help diagnosing it from there.
factory is around 28%Does anyone know what the duty cycle is for our injectors from the factory or their flow limits? Curious if they are running over 80% when running any form of tune.
I'm assuming they did. The part number listed says it's a set. I'll ask on TuesdayWow bad luck man. Did they replace all the injectors last week?
we know what "assume" means lol. Gosh this sucks man, good luck TuesdayI'm assuming they did. The part number listed says it's a set. I'll ask on Tuesday
CHeck this out... may pertain to you....Reflashed the tune yesterday and fired my car up at night and today just now.
Didn't misfire at all last night or this morning.
Thanks for this, it seems thats why the "Honda tech line" advised my dealer to swap the injectors right away? Maybe this is a known problem that they know about and not us.CHeck this out... may pertain to you....

Ill post the post here too in case the group is private.....
Thought I would share.
Many of you know I am a 15 year Honda master technician. Today I was working on a 2017 civc hatch with over 38k on the odometer!
Had a very bad missfire. (Check engine light) most of it was in cylinder 3 but 2 was acting up too. Did the basic swap coils and plugs to eliminate spark plugs coils exc. no change.
Broke out the compression tester. 240 across all 4 cylinders. But a cylinder leakdown test showed cylinder 3 leaking 20%!
I pulled the valve cover off and checked the valve adjustment. Right away I found one exhaust valve on cylinder 3 very tight, causing the valve to hang open hence the leak.
Figured that was it. Put it back together retested and zero leakdown on cylinder 3.
Fired it up. STILL HAVE A BAD MISSFIRE IN 2 and 3!!!
Next step was to swap injectors. Since the 1.5 turbo motor is direct injected, and the car still under power train warrenty, I ordered a set of injectors and the required gaskets and feed pipe.
Installed them and why do you know. Fixed the car. Runs very smooth now.
If you look at the pictures it appears excessive carbon buildup on the heads of the injectors caused a odd spray pattern or clogged the injector.
Direct injectors bolt into the cylinder head. Not into the intake manifold like normal injectors. This way you get gas directly into the cylinder. The injectors operate and a very high pdi since it has to overcome combustion pressures. Add a turbo and it gets high! Hence the loud injector sounds.
I don’t know what type of gas this customer was using but I do recc using only premium gas and run quality gas.
