Robert OSELLO Posted December 26, 2000 Share Posted December 26, 2000 Did anybody heard about a swiss company named Digital-Motors, whose business is to provide chips to upgrade existing engine management. http:\www.digital-motors.com They claim to have a chip for S7 1.6 K Serie, which will increase power around 22CV and torque about 20%, at 300rpm less than the factory release. It fits in the car within 15mn, without any knowledge and prerequisites. Pricing is very attractive, so it surprise me a little bit. May be Swiss Low Flyers have some idea about this upgrade? Robert.

Mick Day Posted December 31, 2000 Share Posted December 31, 2000 Perceived wisom is that no one (as of yet) has been able to modify the Rover MEMS except Rover. Let the buyer beware! Mick Link to comment Share on other sites More sharing options...
CHRIS CLARK Posted January 1, 2001 Share Posted January 1, 2001 Go on Robert, try it and let the rest of us know your results! (Says he with a wishful thought!!!)thumbsup.gif or thumbsdown.gif Link to comment Share on other sites More sharing options...
Robert OSELLO Posted January 1, 2001 Author Share Posted January 1, 2001 Well, it seems no serious feedback will be available right now. I share the same feeling as Mick. Chris, I don't feel good beeing the first one to try this upgrade. I'll stay tuned and probably go back to the Caterham Supersport upgrade. All the best (S7s) to all of you during this new century, Robert. Link to comment Share on other sites More sharing options...
Pierre Gillet Posted January 1, 2001 Share Posted January 1, 2001 Your are correct Robert, it seems "too beautiful to be true" as we say here [:;)] By the way welcome back. Pierre Link to comment Share on other sites More sharing options...
CHRIS CLARK Posted January 1, 2001 Share Posted January 1, 2001 Robert. You should have been braver a few months ago by buying 'Rover'(the whole outfit!) for 11 UKP's and then getting the research dept. to sort it!!!!! I tend to agree with the 'nothing is for nothing' approach but then there are exceptions where you (no, they) get something for nothing...... tax man, my ex-wife etc. Link to comment Share on other sites More sharing options...
Robert OSELLO Posted January 2, 2001 Author Share Posted January 2, 2001 Chris, "Dam..d!!" I missed this oportunity! Can you imagine that: lots of engines on the shelf, a research department to think about K Series upgrades, all this stuff for only 11UKP's!!!! Let me know if you hear something about Vaux... Cheers Rob. Link to comment Share on other sites More sharing options...
CHRIS CLARK Posted January 2, 2001 Share Posted January 2, 2001 Yup; they're overweight & ------- Oops; No offence intended Alex!!!!. Good engines, but I prefer 'K's OK? Link to comment Share on other sites More sharing options...
Pierre Gillet Posted January 16, 2001 Share Posted January 16, 2001 I read that the new Lotus Elise powered by the 1.8K has now 4 BHP more ( 122 BHP)by using a Lotus engine management replacing the Rover. This probably gives a good order of magnitude for this type of optimization. Question is what would be the price to pay for such a modest power increase?

Peter Carmichael Posted January 18, 2001 Share Posted January 18, 2001 The Lotus ECU will just have plumped up the part throttle fuelling. This will give better immediate response to the throttle and worse fuel economy. If the peak power has changed it will be in correcting a fuelling fault in the original MEMS. The sorts of things that give the MEMS a problem are fundamental installation differences such as exhaust configuration which mean that the engine gets to breath a bit deeper at various rpm. If the fuelling isn't adjusted to match, the mixture will go lean and the power curve will be a bit disappointing. The problem with an "honest guvnor" bolt on chip is you have no ability to audit its activity. It might be a placebo. I have found the use of the Emerald M3D programmable ECU to be a liberation and an education. Link to comment Share on other sites More sharing options...
