Cars and remaps

[Ant1981]

Remaps reduce the safety margin on the engine in terms of reliability.

Really?

Theoretically yes, but the people getting remaps more than likely give to f**ks and as stated will look after the engine far better than your average joe.

Are you chaps getting confused between reliability and someone thrashing it?

I don't see how it's more unreliable, there's just more power there, but doesn't mean you have to use it.

To be fair I'm not clued up on the turbo engines, but say a standard turbo will boost to 15psi and a remapped one will boost to 25psi, that 10 extra psi puts more stress on the internals, the piping, intercooler, etc. A tuned engine will always require more maintenance than a completely standard engine as parts are stressed more.

I see what you mean, but only if you're giving it more beans though I think? A bit like any mechanical part really having more stress though it, even a non turbo vehicle being driven hard, the mechanical parts are under more force and torque.

there are other parts that would need uprating too so cost would be a big factor IMO

A lot of it is do with emission rules, driving cycles, drivability for the masses, insurance groups ect.

How would putting one of your maps on the car increase emissions? Surely it would be down the driver and there driving habits. Some maps increase fuel economy right? Could the car company's not play this economy card and then charge more?

the way I see it....each market would need a different map (fuel quality in the uk is better than france which in turn is better than eastern europe). At the moment they have 1 map that can take all these different fuels and still run fine. I guess with many uk maps they are designed for higher octane fuels?

(I remember tt saying his rs4 could run with 92 ron if needed!! but the engine would reduce power to compensate for the crap!)

emissions are checked over the whole rev range and not just tickover I think, more power = more fuel so emissions would be up

and then they add extra filters, and charge a bomb to service it.

clever really

I rarely believe any car manufacturer that says "cheap to run". Somewhere they'll make up for it. 

Be seeing a LOT of breaking Prius in about 5 years time I reckon, all the 07 plate ones with their failed batteries, costing THOUSANDS to replace.

All down to warranty costs plain and simple
