There is something odd going on here.
If you accelerate with the box in auto when stationary with the handbrake on, does the car try to move immediately, or does it feel like the clutch has to engage first?
My car feels like the clutch is engaged all the time with the handbrake on, as soon as the handbrake is released enough, but not completely, the car will start to move under power without any pause, clunk or rev change.
If I do this with the foot brake, the clutch doesn't engage until the brake is completely released, then there is a slight pause, a clunking noise and a slight jolt as the clutch engages.
This is on a Dec 2006 registered 07 model

Guys.. you are somewhat wrong

Firs of all - 'dabbing' brake will *NOT* disengage clutch (only for that short period).
For clutch to be completely disengaged you have to keep brake pressed (lightly is enough, just so brake light is on).
Same goes for *handbrake*! While car is stationary, and handbrake is on (light on on
dashboard), clutch is again disengaged.

But, if car is moving faster than approx 8-10km/h, than applying brake/handbrake will *not* disengage clutch. Car has to be stationary.

So why does my car creep forward on level ground with the handbrake on enough to put on the light on???

In my case.........

When I am reversing into my garage the speed is too great and I need to slow down with the footbrake.

When I do, the clutch disengages and I need to dab the throttle very lightly to resume rearward motion otherwise it starts to roll forwards as my garage is on a very slight upward incline.

Foggy69, Kremmen -what year model is your Civic? Mine is 2007 (although delivered at December 2006). Maybe there's some difference in i-shift firmware?

I for sure know that mine disengages clutch completely when I lift handbrake (I can feel it disengage as soon as handbrake light pops on).
Same for creeping forward (or backwards if in reverse) - handbrake needs to be on, or brake pressed, otherwise it engages clutch back on.

[Kremmen]

Mines the latest 07 firmware.

As far as I can tell on mine the footbrake does disengage the clutch momentarily but the handbrake doesn't seem to because releasing the handbrake and it creeps.

Same here as it should be as Kremmen and myself got our cars around the same time

[Foggy69]

Mine is a 2007 model bought in Dec 2006, so it doesn't have the updated software.

[Nick7]

Mine will creep forward when I *release* handbrake too. But as long as it's pulled up so much that light goes on, clutch is disengaged (you can feel it).

Of the back of what Endemo wrote i telephoned Honda customer services they confirmed that they are working on new software for the pre upgrade I-Shift models and although there is no fixed date for avalability they are not to far away. Good news for anyone who wants a smoother ride in what i think is a great car already.

Now then ive just paid £140 for road tax for year but car was released from factory on 3/01/07 so has it had the upgrade i cant tell any difference between the the test car 06 plate i shift and mine so am i being ripped off?????????

[Kremmen]

The latest software upgrade as far as I know was started mid Feb at Swindon. This had to be done at the factory so I suspect you may be paying too much road fund.

I wonder if the dealer has any diagnostics to identify the software version?

My 07 model 1.8 i-shift Civic registered in Sep 2006 has a CO2 emmissions of 149g/km and therefore just sneaks into Band C tax which was £100 last year (now £115).
Current i-shifts are shown as 158g/km and are therefore in Band D which is £140. Your V5 registration certificate should show the correct CO2 emissions.

was your car released on the 3rd January 2007 (lower Co2)
or are you american in which case
your car was released on the 1st March 2007 ( Higher Co2)

Cars prior to 1st March had the old software
cars after 1st March have had the upgrade

One of the main changes is the way the newer cars use the gears

For example the older cars could be in 6th gear by the time they were doing 40mph (more or less)
and the newer model only slips into sixth gear when nearing 60mph
(more or less) the actual changes are slightly smoother also

you need to know your stuff to notice the changes

Hi all
as far as i am aware the upgrade to the i-shift gearbox was designed to sacrifice mpg slighty to try to obtain a slighty smoother shift. i shift built from early 2007 should all have the new software installed.

regards

that was one of the reasons
The upgraded cars hit the road from 1st March at the '07 plate change
infact our car was at the dealers a few days prior to 1st March
and had to go back down to Swindon to have the upgrade done

Mine, with the old software, does not change into 6th until 60mph or more if you are continuously accelerating. If you lift off earlier, it will of course change up. I think the differences in software are minor and certainly the £25 saving on road tax with the old software is well worth while.

foot down building up speed - that I can understand

I have heard people with the old software saying that when they are driving through towns or cities doing around the 40mph mark the system
will slip through the gears to 6th gear


This doesn't happen with the new software ( this is where the MPG issue comes in) Having driven cars with both versions of software
I have to say I am much happier with the newer version although there is still some room for improvement.

Hi guys,

I hope to take a long test drive later this next week in a 1.8 i-Shift Sport. Whilst speaking to the dealer on the telephone, he mentioned that ALL i-Shifts are to be the subject of a recall next month, October, 2007. It struck me as being a little odd, ie being aware of a forthcoming recall. Anyone else heard the same and if so, the reason why please. Still dithering.....

[Kremmen]

i-shift recall...................

Oh - lets hope so

As Biker1 said - lets get rid of the row-boat sensation.
