Hello guys,

I have a catalysed Sierra Cosworth 4x4 standard specs. But do I need to have a non-catalysed ECU to be "live mapped" if I want to live map my engine ? Or will they do it with my cata-ECU ?

Also do I need to first buy an uprated chip to be mapped or can I just give a virgin chip ?

Thanks for the answers !

 

You will need to ask the people that are going to do the mapping for you as it would depend on the software/programme there going to use to do the job
