They work ok for a budget ECU, I find it hard to get enthused about them after mapping on things like autronic SM4 and SMC etc, but if he only wants to spend that sort of money they are a good honest ECU for the money.

Really not a fan of the mapping software on them though, I keep looking at my watch to see if its 1987 again when im using it as it feels like ive stepped back in time
