Good evening to all, is there anyone who has ever had under the hand, these control units for Suzuki Jimny M13A 1.3 16v petrol DENSO 1122000040. It is a vetturina prepared for Off-Road, would like to reduce the engine torque and, if possible(I see hard) to give some horse. You know what results you can achieve, you go to the OBD or no?? Well some iiformazione.
Thanks to all
