Stage 2 Performance Software for E36 M3, MZ3 (Turner-Porsche 3.5" HFM, larger injectors)
Conforti Shark Injector performance software tuned for our Stage 2 OBD2 package – larger fuel injectors, Porsche 3.5” HFM, and intake. This is the correct software to use with the desireable Porsche 809 HFM on the OBD2 E36 M3. You should not be running a larger HFM without software and injectors - you're in danger of running too lean! On the dyno we found that the stock fuel injectors were not capable of providing enough fuel to keep up with the increased airflow. This "leaner" fuel mixture was dangerous as it could lead to hotter combustion temps and burning or melting of critical components. With the correct HFM, larger injectors, and this software you will be back to running correct air-fuel ratios.
The rev limit is raised to 7000 RPM with the top speed limiter removed. Works with 91 or higher octane fuel.
"24lb" injectors (actually around 26lb injectors when used at the S52's 3.5 bar of fuel pressure). You must confirm the injector flow-rate at 3.5 bar before using this software. At the time of your order, please provide us with the Bosch part number from your injectors.
Porsche 809 3.5" HFM (0 280 217 809) (TMS/Porsche HFM works best) with intake. Note: this will not work with a Euro HFM, 540 HFM, or Dinan HFM. Our software is programmed and written specifically for the Porsche 809 HFM! At the time of your order, please provide us with the Bosch part number from your HFM.
