| The ss injection system does not have an 02 sensor in the exhaust system so, it has no idea what the mixture is doing. If you fit a free-er flowing filter and pipes then the chances are that you will need to check the mixture - if it's burning lean then you may well cause some long term damage. If the injection is like my 800ss system then it's completely unadajustable so, a PC or an FIM Ultimap ECU is the way to go. |
