Hi,
just been looking to get some extra umph from my aging diesel and thought about adding a chip box as my friend has done - definitely works! But which one to fit....

In the UK they all seem to want to relieve me of £300-£350 quid whereas Race-chip.com which is a German company (where most of these are actually made) only want 130 euros.

Anyone fitted one of theirs or got thoughts as to how well they work?

thanks in advance

What car and engine do you have first off?

FIAT Multipla 110BHP 8v 1.9JTD

This is weird.

I was gonna post a thread on the same topic tonight.

Looked at a few on ebay, ignored those daft ones that are merely a resistor and are a couple of quid, and thought it would be £100 well spent - if what they claim is genuine.

I have a Honda Accord 2.2 ictdi.

Anyone any ideas on what the difference is between these two, other than name and cost?

Edit - need to add ebay into the links due to filter - sorry about highjacking the thread OP.

n2

One of them stipulates that it's 'digital' but I'd assume they both are...

I wouldn't touch a chip like that, regardless, you need your car properly remapping, using somebody like angeltuning (big in the Fiat JTD sector). Your clutch will be a weak point though.

Listen guys, NEVER use one of these boxes, all it is in the box is a cheap resistor which fools your ECU into over fueling the engine. You will eventually knacker things up, your mpg will drop and you will be pumping out loads of black smoke.

Save up and get an engine remap. You can get a reliable and proven map for around £300 (generic).

This will be a lot safer for your car, almost undetectable, will raise your mpg, will not cause loads of smoke and can give you around a 25% power gain.

The clutch is a weak point as your torque will increase greatly, sometimes above the safe limits of your standard clutch, causing it to slip. Mine started doing this, so I upgraded to a Sachs racing clutch kit.

I'm currently running safe at 200bhp, 330lb/ft torque and can still hit 60mpg.

Too many horror stories on the various owner forums. It is not true that the box is just a resistor, it is a form of tuning unit, but they just don't seem to work well.

Have a look around, they are all based around the same principle of over fueling the engine, hence why they are crap !!

Ahh, ok thanks.

I think Chris didn't read my post regarding the resistor ones, which these aren't.

Might look into getting it professionally remapped then.

One question that always comes into my head about this remapping carry on - why didn't the car manufacturers actually optimise their engines in this way from the offset?

I know enough about them not to need to do research, of course that is all that mapping does, increase fuel and turbocharger boost, little more. You can call it what you want, but it isn't anything particularly clever. You can also say it changes the map it uses for the fueling, but all it does is...increase the fueling on the map.
#11
All kinds of reasons.

Reliability, engine wear, clutch issues, consumable items etc

A lot of cars have identical engines, but different maps for different power output ;)

The remapper will tell you because the car has to be designed to work in different environments using different quality fuels, but the UK is lucky in both respects.

As a chemical engineer, my view would be that the manufacturer has optimised reliability with performance, and increasing the performance will mean you lose reliability.

Most have differences, smaller/larger injectors, larger turbochargers, reworked (read stronger) internals.

Sounds a fair enough answer, cheers. Have some rep.

hmmm somehow I began to guess that this wasnt an easy subject. My friend has a box which he paid around £300 for but the company he got it from no longer trades. It is working well (atleast on the drives we went on and he can switch it on or off). He has currently had it fitted to his company car for 18 months with no ill effects and just takes it out when it goes in for servicing. Dealer hasnt mentioned anything strange - 5 mins to refit and hes back in business.

Accept the issues about reliabilty, but we are talking about a Fiat here so they arent strongly connected anyway :)

Oh and before we get Fiat lovers on my back, I own the Multipla, have a Bravo 150 Sport for Company Car and until recently spent 16 years working for Fiat.

Thanks for the input so far and if anyone else has anything please post.
#16
Remember that the JTD is a good engine as is the running gear on the Multipla, the main issue of reliability for Fiat are silly little things.

The remap will kill your clutch if it is already worn, it is something to be very aware of.

marmalade47 - my father in law has one of these on his Stilo Estate (17"alloys as well :lol:) and it certainly moves. He hasn't had any problems with it afaik.

pghstochaj - what about a remap on my Accord, would that kill my clutch just as bad or as I've been led to believe, the Honda clutches are pretty durable.

I thought about doing it on a HDI 306 2.0 but then I was told I would need to get a different clutch 'uprated clutch'?

yeah unfortunately, I am already on my second clutch after only 35000 so they dont last long and are expensive pieces of kit to change. Maybe I just have to toodle along and enjoy the countryside a little more :roll:

If you get a custom map, you can get the torque limited to avoid clutch slip.

It's the torque that kills it.

New racing clutch (minus flywheel), will cost you in the region of £500+ fitted (think mine was £700ish)

It's so very specific to the car, I can talk reasonably about Fiats because I used to be quite interested, but couldn't speak with any authority, so won't try.

The general comment is of course, you are putting more torque through an item which has been designed to last 50k to 150k with the standard torque. If you already have 100 k on your original clutch, it is unlikely to last a great deal longer.

It depends on how good the Accord clutch is though. You could look at the DDS170 (?), 180 (?) is it, to see if it has the same clutch for comparison.

No use if they do not produce an uprated clutch for your car.

My car has to many faults to bother with it. Thats what my mate said as well. Would be nice to play with, I've heard you can get them to produce between 110 to 130 with just doing that. Don't know how true that is.

Are you always this awkward ?

I'm sure the OP will check that out if he decided to go down that route before getting a map.

Plus, as stated above, you can get the torque limited so you can keep your standard clutch :whistling:

Awkward? I think you will find that people are interested in the pitfalls of remapping and tuning (hence this thread) - therefore it is important to highlight issues to them. If you don't point out such things, other people will. Otherwise it would be a case of "yes you can get your car remapped" and everything would have been done and dusted after a few posts.

Clutch limiting would mean you may as well not have had the remap, especially on a diesel.

Well it's important to highlight all avenues, especially as this is a remapping & tuning thread.

Ps, just for the OP's benefit, I had my map torque limited after it started slipping & it was still much more powerful than standard. I then got the map torque bumped up when I got a new uprated clutch.

I didn't declare it for a couple of years (which I DO NOT recommend - it "could" invalidate your insurance if found).

I then went with Greenlight, they accept remaps for free (i.e. it doesn't affect your premium). I'd recommend getting a quote off them 1st.

Diesel clutches are uprated anyway.

Compared with what? A petrol clutch? Well of course they are, just in the same way a 3 litre V6 has an uprated clutch over a 1.6. The clutch however would normally be sized for the torque output of the standard car, not uprated for potential future mapping. Hence it is a relative term, with uprated meaning from the standard type.

OK, thanks for the input guys - rep added where appropriate and I think I'll perhaps resort to relaxation lessons and a more relaxed approach to motoring :)
