We highly advised you send your ECU to us for modification to prevent any incompatibility issues in the future. Customers have succeeded in fitting a different vehicles ECU with immobilizer removed but also customers have not so there are no guarantees. Stage 1 : Ideal for tuning using all stock parts Stage 2: Max Effort from a stock 6mm pump advised to be used with our intercooler, hybird turbo & exhaust system Custom: You would give us the requirements of your build i.e larger pump, turbo etc. and we will have this modified to suit your needs. Again there are no guarantees with custom tuning like this. It cannot be done remotely to perfection (your mates HX35 may well be different to HX35's we have tested with etc.). This is the same with any ECU tuner in this field.
