This Stage 4 software fits the following BMWs:
1996-1999 E36 BMW M3
1998-2000 Z3 BMW M Roadster M Coupe
Stage 4 Performance Software for E36 M3, MZ3 (HFM/Cam/Header Kit) (stock S52 manifold)
Conforti Shark Injector performance software tuned for the an awesome OBD2 package – Headers, Schrick camshafts, "24lb" injectors, Porsche 809 3.5” HFM, and intake. This software is tuned around the stock S52 intake manifold. For keeping the most useable torque we recommend using the stock manifold over the M50 part.
With this software, and the rest of the Stage 3 components, you will notice more top end power, a broader torque band, and a smoother running engine. 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.
