thanks for the input lads. I have read and reread all the posts on here and a couple of other sites aswell - mainly cos I can read quicker than I can type LOL. We have tried a knock sensor. We have coded the injectors using the original delphi and tried it in injector sequence and cylinder sequence, we have also tried coding with the X431 which definately uses the injector sequence. Currently the car is going to someone with ids to reflash the software (suggested by delphi) and obviously we will get them to see if the injectors will code properly.
Thanks
