The stage 2a ECU upgrade is finished
First of all: big thanks to Tony for coming down to help us produce the new map. Much appreciated
Tony's car had the following modifications:
Apexi air filter
Blocked dump valve
Uprated fuel pump
Profec B boost controller
Type 1 FMIC
Turbo back exhaust
Standard AFM
Nismo 555cc injectors
H-Dev manifold
Uprated actuator
Tony had all the parts fitted before he came over so all we needed to do was to map the car. I rigged the car up with my mapping gear: Wideband lambda sensor, knock detection equipment and my ECU remapping hardware. I initially mapped the car on the road, to get it pretty close to what we wanted. When this was done we went along to Surrey Rolling Road.
Here are the final results. We managed 300bhp and 305ft.lbs of torque at 1.3 bar peak dropping to 1.1 bar (this was the most we could manage). Lag is also reduced - we get 150bhp at 3500rpm compared to 125bhp with the standard manifold / stage 1a setup.
