Hey guys, I purchased and setup the Autel BT dongle today and while I was making sure the tool could assist with my rear brake pad change, I started looking at what other info the unit could provide. I noticed that I might have a potential issue... What do you make of these failed results and is the number of misfires normal for these time spans/drive cycles. Lastly, what are "normal" parameters for AFR at idle, cruising and WOT? For reference, I have the PRL High flow intake, catless DP, FP and IC paired with an OTS Hondata map. Car has no DTCs and seems to run fine. Thanks in advance.

Sorry, I don't have an answer to you question but i am assuming that the car "feels" OK?

I am intersted in whether the dongle allows the reset of the EPB, can you confirm that is the case and if so what model of Autel is it please?

I have to keep borrowing the diagnostic tool to do my rears (I have changed 3 times this year so far).

Thanks

I purchased the Autel AP200 from Amazon for $60. I haven’t changed the pads yet, but I did run the EPB into maintenance mode and could hear them release. I took them out of maintenance mode and the EPB worked fine again. Easy solution to your problem, so I’d suggest you pick one up.

Thanks, the last Autel diag tool I purchased in December 2018 would not work on the CTR (FK8) so this is good news indeed and well worth $60 just for the EPB feature alone.

Just ordered one, from Amazon as they offered some extra discount today, so it cost ÂŁ55.99 in the end, result.

hey. i'd say that having numbers like 1,2,3,4 missfires seems fine to me; think about how many times the cylinder has fired in the last 10 driving cycles? for me that would be somewhere around 800,000 or 900,000 times that a spark plug fired in my engine. so having 4 missfires out of almost a million firing events? that seems WELL within the OK range to me. now I saw that it said something like 'out of the last 200 revolutions' somewhere in there too? if its missfiring 4 times out of 200 revs then thats NOT ok.

as for the AFR readings -- in a typical turbo car, at light cruise and idle you'll be very close to stoich; somewhere around 14.7:1. under heavy acceleration it'll be richer; totally depends on your tuneup of course (since you are Hondata tuned), but for my EVO VIII I had it tuned to 11.8:1 at full throttle. my Honda EG K24/20 BW EFR7163 we run at about 12.0:1 at full throttle. I honestly don't know on our CTRs (mine is bone stock right now) but since it is direct injected I'd expect that it could run safely a bit leaner than my port injected cars; I'd bet that around 12.5 or 12.8:1 at full throttle would be safe and strong.

charge your phone, you heathen!

Hey, I figured if I’m gonna run lean, I might as well press my luck and run my phone battery on 1%...lmao

BTW, here are the A/F ratios I’m seeing:

Idle: 14.5
cruising: 14.5
Coasting while in neutral: 29.4
WOT: 11.8

Another thing that I was thinking about is that some of the avg misfire values for the last 200 revolutions were higher than the last 10 drive cycles. Which seems backwards to me...maybe “revolutions” means key cycles and not engine revolutions? Not very detailed instructions included in with the Autel.

Got the dongle today and downloaded the Honda diagnostic tools but it won't talk to the EPB, so I guess your US cars must have different coding. I have even tried selecting US and General models with the same result.

I didn’t realize you weren’t in the US...I’m sure you saw the screen where it asked you to pick your country. You selected yours and it still didn’t work, or was it not listed?

Edited reply:
I got it working!

I was selecting (logically I believe) Brakes under diagnostics and then EPB.

I got it working by using the Service function on the home screen and then EPB, after a few options and minutes the brake pad change mode came up and worked fine.
