Another check to the DPF, after a few more kilometers since the last automatic regeneration. After 262 kms, we have 3.6 g of PM (particulate matter) in the DPF.

 

And another check.
Great! 4.3 Liters per 100 km = 65.69 MPG

 

Will be interesting to see how far you travel between regens and over what time

I am completely in the dark at the moment about my dpf, just assuming it passive regens when it needs to but there is no real indication of it happening.

I have read that the range dropping suddenly can indicate it but the range meter on mine jumps up and down quite a bit as you are getting better/worse economy.

When it goes in for service I might ask them to give me some details of frequency of regens if it's possible to get that from the log

 

When I have the time, I'll be taking a look if HDS can retrieve past regen logs. Didn't remembered that. Good point.

 

Olá Joooe!


I'm wondering if the Honda HDS software you're using has some sort of throttle position reset available.
I've read in the workshop manual of my 8gen that, being electronic, a throttle body cleaning should always be followed by TP reset.

The only piece of hardware that granted this (other than going to the dealership) is something like 170 US dollars. But this cable you bought appears to be at a much more reasonable price.
Have you found that in the software, perhaps? Could make me consider buying a unit for myself...

 

Out of intrest, which HDS cable did you purchase? I have a generic read only one, but I'd like to get one with the more recent software for better 9G compatibility.

 

I bought this one: https://www.ebay.co.uk/itm/New-For-...t-Have-Tool/322811302857?ssPageName=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

Chinese product, but enough for what I need.

 

And a regen has happened!
It seems it has started at around 500 km since the last one. That or 10 g of particule matter.

 

Cheers for that. What sort of driving do you do out of interest, mainly motorway, town or mixture?

500km is about 300 miles which rallies with standard guidance for regens. Presumably you had no idea it happened other than the log ?

 

out of interest where did you get the software
I have a old xp laptop I use for tune ecu for my bike

 

You have PM. :wink3:

 

A mixture of motorway and town driving. Yep, no idea it happened, I suppose it's very subtle. lol

 

Hi joooe, I've ordered the same HDS cable as you linked, any chance you could advise me on the software? Thanks in anticipation.

 

Hds



Can't send you PM!

 

Posted a message in your profile. Check it out.

 

Cheers joooe, once my dongle arrives I'll let everyone know how I get on. Now I need to pick the best laptop for the job (working in IT I have lots of old laptops to pick from!) :wink3:

 

Do I have to use Windows XP? Also that cable is out of stock ((

Edit - Could you also PM me the software please? I am going to try and source an XP laptop from somewhere

 

Do I have to use Windows XP? Also that cable is out of stock ((

I guess so. At least with some versions of the software.

Most enlightening. Please us posted.

 

It would very useful if you could compose a post outlining how you reach this point and what it means. Looking at your later screeenshots it appears that there have been several regenerations. Were you aware are that they were taking place?

 

Yes, my goal is to get to know a bit more about DPF's way of operating. This thread is a follow-up of a regeneration interval - there were 500 km between 2 regenerations.
I have an obd2 reader connected to my android 2din and I can monitor temperature with the Torque app. In one trip, during the day the regeneration took place, temperature got to 90ºC faster than normal. That is something to note. Other than that, during regeneration, cooling fan starts working too.

 

Do I just need that cable and that's it? I don't need the £100 HDS module?

 

Just the cable, yes.

 

And the software

Do you still have your copy of the HDS Software files? I've got that cable, funnily enough, but an older version of the software.

 

This could be an option for win 7 laptops https://www.microsoft.com/en-us/download/details.aspx?id=8002

It's funny with the regens as my wagon 2.2 IDTEC is going to over 1000 KM between regens

Excellent thread Joooe, very informative

iVE A 2012 2.2 Diesel that has done about 50K and to my knowledge it has never had a regen. It is never used on short journeys. So it would seem unnatural for regens to be taking place at 1000 km intervals.

I do have the Honda software and am keen to have a look at its present condition.

I would appreciate any further knowledge on this subject

 

Regen will happen no matter the driving style in cars with dpf.

That's not true in my opinion. The car needs to get the heat up before it will kick of a regen. You need to be driving for a consistent period for the regen to complete. You need to drive the car on to get the engine up to a proper temperature for the regen to happen. I know my wagon is doing the regens between 1000 - 1200 km as the fuel consumption will drop and lasts for about ten mins.

I was at around 800 km but I took the DPF out and cleaned it. I would need to get the software to test it for sure but I know when they are happening in the car.

 

That makes absolutely no sense to me.[emoji53]

 

What part makes no sense to you? Some of this is in the manual so it's not new

 

For passive regens you need to be doing longish trips every so often and get the engine up to temperature, if you don't then you will get an active regen where the car intervenes and injects fuel into the system.

I've done 1000miles so far and not noticed any regens at all although I am certain they have happened but I do long trips on the motorway.

Maybe the passive regens aren't obvious but active are as more fuel is injected so you notice a dip in economy
