Hondata

Update: This issue (suprisingly enough) was a fouled plug and coil pack. Apparently, some FK8 are afflicted with water ingress into the spark plug well, causing the pack and the plug to foul out.

Updating this long overdue post: Issue remains. I attempted to reflash with the OTS Hondata Flexfuel tune, Attempted a boost leak test with around 5-10 psi and ckecked couplers and hoses seems okay per what im seeing, not 100% on it though. posting calibration as well as latest datalog for assistance.

I will post it a bit later today, thanks for the input from both of you

What I find bizarre is this is the Hondata OTS Flex Fuel tune. I'm assuming there could be other factors causing this issue? I've run the OTS without issue for years. Can we assume faulty wastegate actuator maybe? Also, if I need to find a tuner for my specific need, that is something I could do as ...

Let me know what Information you may need and I'm happy to provide it. Your help is greatly appreciated.

Thank you for the analysis, I will take a look asap. I'll pull the current settings when able and post them

Before checking hoses, I went ahead and reflashed the tune, and pulled the battery for a few. no real change, here are a couple more log files, hopefully these are good enough for analysis.

It has for oil. the only thing touched was the catch can being emptied.

Another thing to note is, if I attempt WOT, it feels almost like fuel cut or boost cut (best described), and the engine appears to make a similar noise to traction control when it hits around 17lbs boost and essentially Brick ...

Hello, Please move if this post is incorrectly sorted. I'm trying to diagnose an issue with my FK8. The issue is seemingly a boost leak, or an issue with the wastegate not functioning properly, or something else entirely, I'm a bit of a noob and just looking for advice. Here is what I know:

I will ...

Here is one more log that is at 20% Ethanol content as opposed to 25%, with the fuel pump duty limit off per suggestion. To me, these AFR's look better, not sure if they are ideal per throttle position, RPM and conditions? I did not do a full WOT pull, just a partial to see if the pump would max in ...

My last question would be why this could have happened with the stock FlexFuel tune? considering i'm only running E30 mixture, this "should " be okay to run, even though E40 is typically the recommendation. Would this be because of octane choice at 93? also, would it be recommended to do a ...

Thanks for the speedy reply, i'll give it a go.

Almost forgot to mention, this mixture is with 93 octane pump gas

Hello,

Having a strange issue with the stock FlexFuel calibration for the FK8.

I have two data logs attached. The log titled "WOT code pull" was a third gear WOT pull from 2000rpm, running 30% Ethanol with the fuel pump duty limit NOT turned on. During that pull and nearing the top end of the RPM ...
