GM LS terminated engine harness

Supports E-Throttle, knock. For GEN III and GEN IV GM LS engines

V1 Features

Target Engines of MaxxECU V1

• All 3-12 cylinder engines (4-stroke)
• Up to 8 cylinders fully sequentially
• Up to 12 cylinders in wasted spark

MaxxECU V1 Inputs

• Intake air temperature sensor (IAT)
• Coolant temperature sensor (CLT)
• Throttle position sensor (TPS)
• Lambda (WBO) sensor. Uses a sensor directly connected to the ECU without any additional electronics. Supports Bosch LSU 4.2 and 4.9
• 2 trigger inputs. VR or digital. Automatic trigger level detection. The signals are processed by a completely separated processor for maximum performance and immunity against interference
• 2 extra temperature sensors. Can be used as switches or to control additional functions
• 2 extra 0-5V inputs. Can be used for additional sensors such as for measurement of fuel/oil pressure
• 2 digital inputs used for example for speed sensors (VR / Hall) or switches
• Built-in 400kPa MAP-sensor for up to 3bar/43PSI of boost
• 8 inputs for EGT sensors. No extra electronics needed

MaxxECU V1 Outputs

• 8 peak/hold injector outputs. 1-2 high or low impedance injectors per output. 8A per output
• 8 ignition outputs. 5V signal to drive ignition modules, CDI units or coils
• 8 outputs for extra features. Can be used to control virtually anything. Fuel pumps, idle control, boost
• Solenoids, nitrous, shift lights, fans, warning lights, etc. GPO 1-7 (2A) GPO 8 (5A)

MaxxECU V1 Technical

• CAN bus for expansion modules, OEM vehicle CAN, ODBII

• Supply voltage 8-22V
• ARM Cortex-M3 120MHz main processor. Three extra processors to handle the triggers, injectors and EGT
• Resolution on ignition: 0.1 degrees
• Resolution on injectors: 0.001 ms
• Updates the fuel and ignition calculations 2000 times per second
• The fastest PC communication on the market
• 50Hz sampling rate on all EGT inputs
• 1000Hz sampling rate on all analog inputs
• Weight: 528g (without mounting brackets)
• 140x106x46mm (excluding protruding connectors and mounting brackets)
• Aluminum casing
