First of all I want to say that this was done by a company in Sweden called V-Tech but I know there´s a huge interest in remapped 320d with the new ECU (177Hp) in this forum. We also did a dyno run with a Spider box fitted which I´ve had since spring this year. That´s the reasons why I´m posting here

The results were:
Stock: 182Hp/365,7Nm
With the Spiderbox fitted: 193,1Hp/443,3Nm
Remapped: 223,3Hp/517Nm

The car felt faster and more alive with the Spiderbox but after doing a proper remap its a whole new car. The biggest difference is from 0-60mph and the reving. With the remap it pulls much stronger right up to the rev limit. It´s also more pleasent to drive since I don´t have to downshift as much as before. I have a friend that has a 330 (e46 231hp) and before the remap he was a little bit faster…now it´s the opposite


Here´s some tests I did with an accelerometer called AP22 which is a very accurate instrument.

43-68 mph (70-110km/h) in third gear:
Stock 4,90 sec
Spider 4,37 sec
Remap 3,86 sec

62-93 mph (100-150km/h) in fourth gear:
Stock 9,39 sec
Spider 7,76 sec
Remap 7,12 sec


Here´s two prints from the dyno. The first one shows stock, box and remap and the second one shows stock and remap.






So I´m really happy with the results. It´s still not a fast car but it´s ok as my daily driver.

Looks nice, congratulations.

Interesting graphs that show how a Spider Box fits between stock and full remap too.

screw 0-60s, screw 1/4 mile races - the only figures that you need as a daily driver is the one you just quoted here and they are excellent - 3,86 seconds to overtake a truck on a single-carriage way... NICEEEEEEE!!

I'm so depressed that a 320d can be faster than a 330i

[Mantis64]

That's amazing, unbelievable even

Their website isn't quoting any numbers for the 320D 177HP.
And they bring the 163HP to 188HP, which is very conservative.

What do they get out of a new 325D??

[remmib]

I'm stunned, 517Nm from the 320d.

How is that possible??

This looks very interesting...am very tempted. Dont V-Tech make children's toys?

[Dj Mastergrind]

I don´t know about the 325d but they have done some 330d both giving about 290 hk and 310 hk. Since Esstuning have a 280Hp map for the 325d I suppose that V-tech can do the same.

But they did another 177hp a day or two before mine which gave 237 hp! I was hoping to get there but every car is different.
I don´t think they ever gonna put my map (around 225 hk) on their website for the 177Hp version. I asked for a little extra power. But talking about impressive. They had a 120d there before mine and they hade about 580Nm in one program but they decided to go down to about 500Nm to save transmission etc. So there´s definite much torque to get from the 2.0 liters if one wants too.

[creepy coupe]

That's a huge torque spike for a very brief period, but then the Swedes were always a bit mental

Interesting
