Different between VDO & MMC in wira

[Izso]

Yours is running the adaptive VDO ECU. Mine is MMC, so I think there might be some difference if lets say yours and mine are using the same cable?

The only difference is you'll need to mess with the ignition timing for more aggressive timing to utilize the cables

Until it knocks.....hhahhahahhahah

Sounds more straightforward than the VDO method.

VDO method? What method? VDO self adapts. You just install the plug cables and drive. One day later and it adapts with more oomph.

When you said earlier it was notorious for adapting, I thought you mean it in a bad way because of the word notorious. I thought something like after it has adapted, the power increment is not there anymore.

Yup, it can work either way, for the better or for the worse.......lol

It works by having a fixed set of parameters.

Say the A/F is set to be ideal at 14 (for example). Your fuel is electronically controlled and you install a high flow air filter. So now your A/F is suddenly leaner to perhaps 11. The VDO will detect the difference and to compensate, it'll pump in more fuel to get the ratio within its set parameters.

In this sense it's a good thing.

But take those air leaker devices for example. Changes the internal vacuum or pressure or whatever and results in a better performing car for whatever reason. VDO detects the pressure is out of its parameters and normalizes it by counteracting with something else (I don't know what). This effectively means your device is made redundant.

In this sense it's a bad thing.

Kapish?

The only more hardcore fellow I know was my ex company the malay jaga. Since he jaga night till morning, he is so free, he slowly wipe his 120Y engine with kerosene. You open engine bonnet, really spotless inside......lol

literally burning night oil using kerosene..

Wipe every night, also no more place to wipe......hhahhahaha
