I fitted a set of 57's with the DP supplied ECU - its not just a chip swap like earlier models its the whole "brain". I found the DP ECU fueled ok but not perfect. If you fit it yourself do not forget to re-attach the black wire under the head of one of the ECU mounting bolts. I have since had a PC fitted aswell and this has improved things significantly. If you don't want to fit a PC to trim the DP ECU you can buy a Corse ECU to replace the DP item which is modifiable, but will cost around £800. FIM hope to have their replacement ECU available later this year which is a further option. |
