Does anyone know if the standard ESL map requires the removal of all cats or just the centre section? Can I leave the downpipe cat in place with this map?
(Andy from ESL is on holiday at the moment so obviously can't answer)

Thanks

He is back in a few days, the 4th rings a bell.

When I bought mine he did ask what mods I had done, these included a full decat, for which he sent a chipset to suit.

 

The more the better

 

I didn't realise you have to de-cat your exhaust to run the esl ecu.
