Seems Eurocherged.com are the only ones left who can tune the ECU of the old 4.2 supercharged engine. Anyone tried them?

 

or I sell you Arden additonal ECU. Then you do not need to remove the car's orginal ECU, send to the USA and worry if the tune works or not. PS. Arden is very, very expensive....

 

Any idea what exactly the Arden ECU changes?

 

It's closed black box without any exact details abotut the tune inside. Arden recommends to use Euro 98 fuel - ie. 93 in the US. Most probably timing is at least changed. The tune is made to work with stock/almost stock boost, sports cats and catback.

 

Interesting! What kind of money are we talking about?

 

I checked out their web site. There wasn't anything for the 4.0 or 4.3; just the 5.0. Prices seemed pretty steep. I'm not positive, but I think an ECU went for about a grand. Even their price for just a S/C pulley was absurd. If their prices were halved, I would have looked into them a bit further.

 

I am not sure are you talking about Eurotoys or Arden. I guess not Arden.
