Stage 5 Performance Software for E36 M3, MZ3 (HFM/injectors/cams/headers/no cats)
Conforti Shark Injector performance software tuned for the highest level of our OBD2 kits - Schrick camshafts, "24lb" injectors, Porsche 809 3.5” HFM, intake, headers, and race exhaust (no cats). This software is tuned around the stock S52 manifold but will work with an M50 manifold as well. This software turns down the sensitivity of the post-cat oxygen sensors so that fault codes and check engine lights for no cats will not appear. This is the full-bore Kit - tuned for every bolt-on upgrade we sell.
With this software 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.
Optional Speed Sensor Delete - Since this software is intended for race or track use only, there is one additional feature we can build into the programming. The Speed Sensor is built into the diff cover - an area prone to excessive heat. During endurance races or very hot track days, the sensor can malfunction or actually melt. If the engine DME does not see this signal, it will restrict RPM to 5500, obviously killing your speed! This optional Speed Sensor delete programming will tell the DME not to care if the sensor is sending a signal or not. It will set the maximum RPM to 7000 RPM electronically.
"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.
Headers (TMS Shorty Headers or similar)
No cats (such as with the AA Track Pipe)
