remap?

[Windy172cup]

does remapping your car ruining/damage your engine after a while or isit all perfectly safe?

 

[kevo66]

depends if the mapper knows what they are doin!

 

[Windy172cup]

wel jms going to be doing it. Just didnt know if it weakens the engine at all, i think not but just cheaking. Cheers

Should be fine.

 

[DanFreemanPhoto]

Should be perfectly safe. Remapping usually makes very small changes anyway, its not completely changing how the engine runs - just slight tweaks in most cases

ok lovely,cheers peeps

Anything that results in increasing the power of your engine is naturally going to increase wear rates. I certainly wouldn't use the word ruin and I'd be reluctant to say damage.
But with more power comes more stress on all the major components, so when Renault will have done durability work based on 166lbs/ft max torque, your going to increase that and in turn reduce the life of the components in the powertrain.
Put very simply, all that is done is richen the fuel mixture to provide a bit more torque, although it looks like a lot of F4R engines have their rev limit raised too. Which if used regularly will have a large effect on wear.

PS: Thinking about it if you drive slowly afterwards (fat chance, don't see why you would drive a cup slowly, lol)) chances are you would help protect the engine, just use more fuel.

No problems whatsoever with the RSTuner maps, they are designed to work well within the engines tolerances.

The RSTuner maps are a very restrained mapping system, they are just designed with keeping a standard car reliable & smooth over a long period of time in mind. You can push the internals of the F4R engines far far harder, just take a look at some of the ITB/Turbo'd cars on here running well over the 210's - the engines fine, but as you mention its just the box & the diff that does not enjoy that sort of power/torque.

Fuel economy is the opposite, in most cases it increases, often to over 40-45 mpg when motorway cruising.

I can vouch for the fuel economy increasing. Ive noticed an increase in my RSTuner remapped 182

Well there you go, from someone who I'm sure has a great deal more experience with mapping clios than me.

I'm sure its safe to assume if your driving hard your going through more fuel, being bassically always above the std mixture at WOT?

Can I ask which bit of the tune offers more mpg on motorway driving? Never quite got my head around that, with injection timing and chamber design being the main drivers. Is the timing late on a std map to reduce knock?
At exactly the same revs with the same torque being produced, has the original map not got multiple injections or something a bit wierd like that?

Not trying to be awkward, just genuinely interested, sorry

tbh i cant recommend i remap highly enough - my 172 runs much better having more midrange torque and peak power whilst also returning better mpg

 

[DanFreemanPhoto]

Although I've felt the benefits of a remap, when I was telling my mate about it, he simply said 'If it's that much better, why doesnt it come out the factory like that?'

I couldnt really answer lol!

My colleague James handles all the mapping / tuning, but I know a few bits & pieces

I'm afraid I'm no map engineer, so for the real detail of how the maps are engineered aside from the results they can provide you would need to contact Henk the ECU engineer from fastchip, his traders section is here

Thanks for that matey, I assume thats a page I can only see if I join up

Generally manufacturers have alot of other things influencing their tune, like

Engine Refinement
Durability
Cooling
Efficiency
Sound
Very Hot Start
Very Cold Start
All different fuels

They have to consider it all, whereas a keen driver in a country like the UK (good fuel quality) who may only own the car for 40,000 miles may have different needs
