jparkes43 Posted July 10, 2016 Report Share Posted July 10, 2016 Hello Wanting to do carb conversion on my 1.4 16v 2001 lupo. I know about the advantages and disadvantages etc so that doesn't matter. just wondering, what i need to do with all the electronic parts i take off etc, i can work with the mechanical side of things thats no issue.

carrera-gt Posted July 10, 2016 Report Share Posted July 10, 2016 Your basic problem is ignition timimg and advance controlled by the ECU, you have two options you can either try to fool the ECU that it's still in charge or you can replace the ignition system with an after market one. Do you have a cable or fly by wire throttle ? Quote Link to comment Share on other sites More sharing options...
jparkes43 Posted July 11, 2016 Author Report Share Posted July 11, 2016 ok thanks, fooling it sounds alright. fly by wire james Quote Link to comment Share on other sites More sharing options...
carrera-gt Posted July 12, 2016 Report Share Posted July 12, 2016 Fooling, will be interesting. You need to find the mass airflow meter because you need that, It may be part of the throttle body if so remove the butterfly and feed the air to your carbs through the hole. if not then use the air flow meter to feed the air to the carbs. Fooling the ECU as to injection is easy just put resistors across the injector connectors at the right value Quote Link to comment Share on other sites More sharing options...
jparkes43 Posted July 15, 2016 Author Report Share Posted July 15, 2016 right ok that makes sense. thanks Anything else i need to know etc?? James Quote Link to comment Share on other sites More sharing options...
mk2 Posted July 27, 2016 Report Share Posted July 27, 2016 I'll be very interested to know how you get around the ignition timing issues. Everything else will be straight forward. After market ignition system is what I'd use. You need vacuum advance, tps/map and Rpms as inputs. Could also use a knock sensor.... I'd also upgrade the cat. My guess is that you may see a 30% power increase at high Rpms. Twin 40-40 dellorto carbs is what I'd use! Great project. Quote Link to comment Share on other sites More sharing options...
jparkes43 Posted July 27, 2016 Author Report Share Posted July 27, 2016 Thanks @mk2 sounds like its quite possible to do. just the fiddly thing of ignition timing James Quote Link to comment Share on other sites More sharing options...
