2.4 - 140 to 170 remap - Page 4

If you have a car you love and want the extra power then go or it. But yes. A chip will ruin all reliability and cause a lot of problems. I know lots of people who have carried out these modifications almost all with issues a few weeks down the line.

Everyone I know that has done it hasn't had any related issues.
But the key is to start with a car in good mechanical condition.

well this is the thing, isnt it.. generally speaking when cars pop and bang as they go past I tend to roll my eyes, I mean, honestly.. lol

there are people who get paid literally hundreds of thousands of pounds a year to design engines for manufacturers, and they really do know what they're doing. limits are set for a reason, with in-depth knowledge of the components and so on..

but then occasionally there are those that are limited for seemingly no reason, or because they want to promote the sale of the next model up in the range, or because the engine was built by another company and there are issues with competition or whatever.. or. in this case perhaps, a few years later and more testing meant they find out that it can handle a little more

this is why im asking first... it's not always clear cut, but generally i do tend to lean towards leave it alone. it's just that flat spot at high revs.. I'll see if i can get it go away with some maintenance as mentioned on page 1 and then we'll see when I'm sure everything is running ok

The limiting on power extraction is also a built-in feature by manufacturers to get their cars to do decent mileage and remain reliable. The aftermarket is more concerned with taking coin from folks wishing to believe they have a race car with millions of pounds invested in R&D when, in reality, there hasn't been.

If you want a MAP for your car done properly you need to speak to a specialist and have it custom coded to your car. Not just some generic map that was derived from 1 car in the research pool. That sort of stuff should have died out in the 90s with off-the-shelf Superchips stuff. Unfortunately it's found a way into the modern world with OB2 hand held uploads and the like. The maps are, for the best part, generic......Yes they do offer a bit more bite but the longer term issues that can create is simply not worth it.

You categorically will not yield a 30bhp increase on a naturally aspirated engine with just a generic remap. You will see 10-15% TOPS and that will require all spark plugs, coil packs, filters, etc being tip top and sensors all working correctly.

There are plenty of 170SE variants on the market. If you want a 170 variant that's the route I'd take personally. It'll have come out of the factory that way and will only let you down in the same way your 140 variant could/would but with the added bonus of factory oomph from the get go.

Unless you are getting into major surgery on a naturally aspirated car with bolt on exhaust profile changes, cam profile changes, head work, compression changes remaps are, for the best part, an utter waste of money.

20 years ago I would have said the total opposite. Hindsight is 20/20.....and my Dad was right!

I would normally agree with the above, however...

The engine in this car is the same as the 170bhp engine, but limited by software to 140bhp. A map written properly will see the full power released.

I once enquired about a map for a bi-fuel I had, that would have taken the 140 to 175, incidentally they said a 170bhp variant would only map to 175bhp as well.

I’d go for it after a good service and ensuring the autobox is happy.

Usually cars die after mapping as the turbo and inter cooler are stressed, neither of which are an issue on a normally aspirated car.

100% agree.

Some guys in Poland made a video about this, can be watched with subtitles if your Polish is a bit rusty:

if you want a remap I can hook you up with a guy who writes the map himself no downloaded of the net jobby
