Performance Chip for GD?

[SuperCNJ]

Guys,

I'm just wondering if there are any decent performance chips about for a 1.4 Sport? Not looking to turn it into a Type-R, but would be good if there's a cheap way of increasing the power and torque slightly so it's easier to pull off the line driving around town.

It's the missus car, but we both feel the low end torque is pretty pants. Really need to rev it hard to pull off quickly.

Cheers

If you would gain more than 10 Nm when chipping a atmospheric engine like the one in the Jazz you are very lucky. I don't think that you will notice the difference.

What it really needs is a larger engine i.e. the 1.5 vtec like the one the USDM get and many other countries around the world.

Come on Honda listen to your customers.................

I have never noticed a lack of power when driving around the town with the Jazz. I am mostly held up by other cars than the other way around. Maybe it's due to the CVT in our Jazz, it rarely goes above 2500-3000rpm in town and when driving 50km/h constantly it drops to 1200rpm.

Larger engine 
Uses more petrol
Increased insurance cost
Why did you buy your Jazz 
Should have bought a Civic R
Be happy with an accommodating  economical reliable Insurable Jazz
I am & want another with an i-shift but will Honda listen
Oui oui

Two solutions, ask the supplier to supply a written guarantee for the perform increase if no response give the cost to your favourite local charity.

My sister has the GE 1.2 and to be honest, I think it's far easier to drive at low revs than my wife's GD. I'm sure it has better matched gearing which helps with low end torque but I would have thought giving the GD even 5% increase in torque would help considering it weighs next to nothing.

As I say, I'm not looking to turn it into a BTCC car, just a little extra beef at low rpm.

Meeder, 10Nm at low rpm say 2k would definitely make a noticeable difference in a car that weighs a little over a tonne. I actually made about 10Nm @2k in my EP3-R (which is heavier) when I had it chipped and the difference in "driveability" was quite noticeable, the car was far easier to drive with less gear changes.

So, has anyone come across any decent "chips" for the GD 1.4? Not the "ebay-resister-in-a-matchbox-specials" please

I would be very surprised if anybody made 'chips' for the GD jazz.  Now if it had a vtec engine you would be spoilt for choice

You can adjust certain settings using the PROFILE mods on the OBD-II reader.  I have never done it on a Jazz but my neighbour tried it on his Hyundai Sonata (2.2 litre petrol engine).  There are 11 profiles available, named 1a, 1b, 1c (to do with fuel consumption), 2a, 2b, 2c (to do with torque curve variances) and so on.  The default was 3e which causes the gearbox to change up at higher revs, thus enhancing acceleration (it is quite a large car), so we changed it to 1c.  He said the car was slightly sluggish but kept it for a month and reported 8% better fuel mileage and by that time had got used to how the car behaved.  Up hills it was just the same. but pulling away from rest was slightly less rapid.

So it is a trade off of performance against fuel economy.  Being a poor pensioner, I'll stick to economy

Changing the engine management settings is not recommended unless you know what your doing......

If its under warranty it will certainly invalidate that.

Choice is yours at the end of the day

never noticed a lack of low down torque on my GD 1.4, in fact other people who drove it said they were impressed with how tractable and easy it was around town and I certainly never had to 'rev it hard' to easily keep up with traffic.  if you buy a car for it's fuel economy don't expect a dragster, if you want a faster car buy a Civic ( I drive a Civic now but wife still has Jazz) I still miss things about Jazz like how easy it is to park, fuel economy, all round vision,  but needed a Civic because I do a lot of miles.

I would check - if her indoors is using supermarket petrol - a definite no-no with the Jazz which won't run on supermarket rubbish (acts like a 4 cylinder engine only using 3 of them), will run OK on 95RON from decent garage,  but just loves BP ultimate or Shell V power (and gives more mpg).  Also check EGR is not stuck this has a devastating effect at lower revs (it's like having an air leak in induction manifold).  If the car has done local mileage the injectors may be crudded up, run some redex injector cleaner through with next tankfull.

Some good suggestions there thanks, but I felt the need for a little more torque at low revs since we bought it. But just had to adjust our driving to it. It's almost as if the flywheel is too light and isn't giving enough inertia.

Don't get me wrong, I'm not saying it's struggling to keep up with traffic - that's not the case. It's only pulling off from stationary and driving at very low revs where you feel the lack of muscle.

So given that no ones suggested any performance chips so far, I guess they don't exist for the GD?

There are a couple of companies here in the Netherlands that offer chiptuning for the GD Jazz. According to these companies the power will go to 94bhp and torque will be up to 136Nm.
None of the companies do it the right way (dyno before and after tuning) and none of them give the rpm figures together with power and torque.

I ran on both supermarket fuel (Sainsburys) and Shell V Power . No measurable difference at all (I record all miles/petrol).   I did the same experiment on a diesel uaris : same results.

A triumph of marketing over reality imo.
