Transmission i Shift change - new software - Page 7

smiffy · 3rd May 2007, 12:31

I've got into the habit of flicking it into first if I have to slow below about 10mph at a roundabout and am not sure whether I'll have to stop or not. That way it pre-empts the possible automatic change at a time when it doesn't matter - while you're still slowing down. You're then already in first when you want to accelerate.

I get it on mine but don't find it dangerous, disconcerting at first yes but not dangerous. I think the problem is that human nature kicks in and drivers automatically put you foot down to compensate this then tells the box that you want it to change down just as it's going to settle into a gear and pull away. so it's not one gear change your waiting for it's two. I find that a bit of patients and not moving your foot everything is fine. When it comes down to it I think the loss of power is very momentary if you don't move your foot

I have found that as long as your foot is properly on the accelerator
there is no problem (if you have your foot just at the bottom of the pedal you are not getting full power)

Shame about some of you guys not enjoying the i-Shift.

My Millie has only failed a couple of times with the box when I've tried to select reverse.

......but forwards it's always been a dream.

Your are a Civic EX owner - with I-shift???

Cars registered on 1st march 2007 and after have been fitted with the new upgrade in the UK - I presume this will be the same case for markets outwith the UK aswell

Why do you ask

Surely this should have been advised to you when you picked the car up
unless of course your car is slightly older then you will have the original system and will not receive the upgrade

Enjoy your car.

The update isn't done by the dealers, so if your car has the older box, that is that.
There is nothing wrong with the older box by the way, I think the update just made it more responsive.

So, the I-Shift's biggest problem is responsiveness.

Brodick · 7th May 2007, 16:05

The new box is slightly smoother and slightly more responsive

Are you find problems with your car funkmaster??
you need to be at one with the I-shift remember that it is not a full automatic and that it is a semi - automatic so when in auto the system dips the clutch and changes gear as best it can

as foggy said nothing wrong with the earlier version either

funkmaster · 7th May 2007, 18:35

thanks for your help, i'm already happy with this transmission, but if i had a chance to have a better one, i'd like to have it.

glad to see you

I have driven conventional automatic cars for many years and currently drive a Honda Accord 2.0i EX. However, I recognise the problems experienced by i-shift drivers when drawing away from roundabouts and traffic lights.

This situation must always be a problem for an auto box controller, since it cannot anticipate whether the car is slowing to a stop (action: stay in present gear until lower speed demands a change - thereby giving a smoother ride) or whether hard acceleration is about to follow (action: decelerate through the gears in order to be ready for subsequent acceleration).

In practice, the box stays in high gear until acceleration is demanded. Then the controller has to decide which of several possible lower gears it should select as the driver progressively demands more power, before engaging the appropriate gear - hence the control lag.

However, the problem is more marked in semi-automatic boxes because the change mechanism (a robotically operated manual gear box) is inherently slower than a conventional epicyclic gear/torque converter automatic box, which uses fast acting clutches to engage the appropriate gear train.

My solution, when poodling about, is to use light throttle pressure out of roundabouts/away from lights and let the box sort things out; when wanting to make good headway, I decelerate manually through the box on approach to roundabouts/traffic lights, selecting gears that are able to give good acceleration at the current engine speed, should acceleration suddenly be required.

Hope this helps.

Charles_Harding · 17th May 2007, 13:41

I just poodle along and it always seems to be in the correct gear.

When Lady H. isn't around i drive a bit more 'lively' and use the paddles as well.

I'm at one with the i-Shift.

all good and well dpeace but some owners seem to forget that it is a semi-auto box and not a full automatic

I have not had one problem with the i-shift as yet and if I need a quick get away the car is always ready and willing

Hi all, brand new member from Bulgaria

I am ready to purchase 1.8 i-Shift version but this thread confused me a little.
What are my chances to get one of those "new" i-shifts...
My dealer is the official for my country and my setup is not avaible at the moment. They said to me that if i order til end of June the car will arrive in later October. So again ... what are my chances.
Thanks in advance

Great forum.

Great forum.

your car should have the lastest i-shift software
the changes were made in February/March

new4hondas · 12th June 2007, 05:57

Thanks.

brian.99 · 21st June 2007, 11:14

hi all, new member here.what a great site this is. my question about the i-shift is this.
how are you supposed to drive it when in constant stop start traffic such as a motorway traffic jam lasting for 30 minutes or more. I ask because this happened to me the other day and the car got hotter and hotter and started to lose drive.the gearbox warning light then came on.lucky for me the jam then cleared and I was able to drive normally and the car cooled down. turned out it was the clutch overheating. Honda say the car should be put into neutral when stopped if you are driving in these coditions (I was in auto mode) but then later told me that whilst stationary the drive was disconected as long as you keep your foot on the brake pedal. Being as this was what I was doing I am more than a little confused. Has anyone else experienced this problem.

allan40alt · 21st June 2007, 11:39

You must remember that the i-Shft has a standard gearbox and clutch. The clutch is operated by the computer. If you are stationary for longer than, say, a traffic light change then I will always select neutral. It's only a quick move of the gear stick, otherwise the clutch is held 'open' and is the same as 'riding' the clutch in a manual car.

thanks for your reply allan, but Honda Technical say the clutch is dis-engaged when your foot is on the brake,so I don't see why you should you need to to put the box in to neutral?

Yes it is, but that is the same as holding down the clutch with your foot and dis-engaging it in a manual car, whilst it's resting in 1st gear. By selecting neutral the clutch is engaged and there are no plates spinning causing friction, heat build up and wear. In a manual car you would select neutral and take your foot off the clutch, it's easier with the i-Shift as you only need to tap the gear lever. Just remember to touch the brake when you select 'auto' again to move forward! I only do this when it looks like being a longer delay than just a traffic light change.
