Hi Panos, I recommend using the base-map from our Audi 1.8T plug-in ECU as a starting point. You will need to enter the deadtimes for your 870cc injectors and reduce the master fuel number so that the AFR/Lambda is close to where you want it to be. You can then tune the tables. Our Audi 1.8T plug-in ECU is intended for 1.8T e-throttle engines, but the Storm ECU does not have the e-throttle hardware. No problem to use the Audi CAN mode, it will already be on in the base-map. Scott.
