I was originally running this car on a Motec M800 system running port injection. I have decided to try running the car on the original DI platform with the stock ECU. I fitted all the original necessary engine sensors - and deleted everything un-necessary - such as throttle flaps, evap system, rear O2 etc. As part of he big turbo DI build I put in the RS4 injectors, ARP HPFP and the RS4 140bar rail pressure relief valve. The Turbo is a Garrett GT30r with a billet wheel and Tial V-band hot-side housing along with a Tial external wastegate. I have a Billet intake manifold and front mount intercooler etc. The car also runs a dry sump oil system.
I am looking for some help with the HP tuners tuning this Bosch MED9.1 ecu to work with my setup. And perhaps a understanding of this ECU's logic to tune it. Car runs and drives but is not happy under load. Looking for some advise on how I can raise the boost/torque etc.. Car currently cuts off at a maximum of 10psi boost. Id like to be around 20-25psi which should be in the 400+ WHP range.
Also the car is ECU only with immo off. It is a caged racecar so no factory modules on CAN (ABS, gateway, TC, cluster, wheel speed, etc..) Just ecu and engine - as if it were stand alone.
I have attached my bone stock ecu map I pulled from the ECU for backup and also my now 4th try at tuning the car.
Help please
