First of all, thanks for using us for your chip. Feel free to call or email us for advise as your purchase price includes technical support. Points that stand out.

1) Are you sure your other ecu isn't a L1? Odd the chip works in one but not the other.

2) Did you actually trim, the CO etc as per your included instructions? You cant just pop it In a nd blast off up the road.

3) Did you turn the boost up to the levels suggested in the instructions?

4) You mention "Greens" a couple of times. Check the part number, should be 080 150 803. The fact they are "green" honestly does mean nothing. The amount of Grey's I get through here painted green is surprising. people love to pull up at meets etc and say to their mates "Its only on 803s" just after they powered past with 420bhp. LOL
