E280 cdi Remapped to 260 BHP

Hi all,
Can someone explain what remapped to 260 BHP means?.

Hi, basically it means your car has been electronically tuned and remapped via a new chip to produce 260bhp.

However that is a massive gain from 190bhp that the E280 CDI has in standard form, I'd ask for proof of the 260bhp figure via a rollling road graphical chart printout from the tuner.

If it is the Brabus Chip that you have installed then the figure is probably right I think but that 260 bhp figure would be more in-line with a 320 CDI engine. However I know the 280 CDI and 320 CDI are the same engines and just have different chips and so the total tuned output can possibly be the same.

190 to 260 does sound like a lot to me. The standard 320 is only 240 so it's a big hike. Check who makes the chip as some are better than others and if that figure is correct I'd probably walk away. Most reputable firms will add 40-50bhp to this engine which implies that a 70bhp increase is not considered a good idea. That said, they may equally have taken the figures from the 320 and simply misquoted them.

We had a discussion recently and the conclusion was that whilst the engines appear identical (3.0 V6 CDI) the component parts aren't. Bearings, con rod, injectors etc will all differ between seemingly identical models to allow for the increases in power - hence a 280, tuned to give more power than a normally tuned 320 is a bad idea.

Any way, expect increased injector wear and other issues over the longer term as the engine is producing a lot more power than the factory intended.

This is more pertinent than you might think. I noted on one "chip" site that their claim for enhancement of the ML270 CDI produced more torque than their claim for the IL6 320 CDI. I pointed this out to them, but they appeared not to understand the comment.

It is also important to be sure that units are "like for like", e.g. be careful that pounds foot or Newton metres is the unit for torque measurement, but not a mixture of the two. From my point in the para above, their marketing and advertising may not be as good as their engineering!

I always thought this but never knew for certain. In my mind I thought some of the internals MUST be different of a 280 CDI and a 320 CDI as otherwise the 320 is going to be under more strain and will not last as long.
