E 320 CDI T-modell manually tune up!!!

[matteus]

Hi,
we have an W210 320CDI stationwagon with about 110.000 km on it (or 68000 miles).
we bought it second hand and we heard al good things about it, especially the engine!
but when I drive it, I think its a little bit to slow when you have to pull away, it misses a bit pit, you know...
so, today we were looking under the bonnet and guess what, YOU CAN ADJUST THE TROTTLE!!!
so I turned it a bit sharper on, and went for a test drive, and well well, it was a huge difference!!!
normally the engines iddles at about 700rpm, but when we came home, it was doing 900rpm, so we really dont know if this is so healthy for the engine.

we turned it back for all safety, but when you own one and really dont want to spend you bucks on one of those chips, you can easily sharpen up your trottle responce yourself.

well, have fun!!!

greetz, matteus!

Not safe.
Because all the electronics (engine AND transmission)
they recognize something called CTP (Closed Throttle
Position) and i mean, they really NEED that, for
example, to maintain correct idle speed regulation.

yes,
I thought that also so we turned it back,
but we're going to buy a chip do give it some more push.
probably to about 235 BHP and 520-550 NM.
seems much safer, although you must be carefull when you're searching for a chip, because a lot of chips get more power by changing te wrong thing, or to much.
example: I last saw a chip for about $200 (wich is VERY cheap), I thought, wow, nice price tag, but, when i contacted an expert it seemed that those chips worked by injecting longer and earlier, so the following happens: when the piston comes back up, the engine is already injecting a lot of fuel, it starts to explode early before the piston is completly up and so the total explosion takes too long. Result: the engine overheates, produces a lot of smoke, and after hard working the pistons can melt. So the engine has absolutly NO reliability anymore.
