ULTRATECH CHRONO

CHRONO

CHRONO

WITHOUT BUILT IN 4MAP SENSOR

ULTRATECH CHRONO is a popular piggy-back device and one of the very few ECUs in the market to directly control injection, just like a standalone ECU. Due to its features and affordable price, it is becoming increasingly popular in the tuning scene. Keeps your stock ECU for climate control, multiplexer, idle routines and faster setup & startup.

Technical details:

• Piggyback or Standalone mode, switchable through free firmware upgrade:
• Piggyback: alters the signal of MAP/MAF or any other analogue sensor and offsets ignition timing
• Standalone mode: directly drives the injectors and offsets ignition timing. ECT/IAT correction
• 4x tables 16x16 (fuel map, two PWM tables, ignition table)
• 8x correction Tables 16x1
• 2x independent switchable maps (e.g. for different octane used)
• Analogue signal modification
• 4x analogue inputs,
• Built-in datalogging memory – log without PC connected
• Battery voltage monitoring and injector compensation in Standalone mode
• Support for frequency output air flow meter (possibility of signal modification) 17Hz-4kHz,
• Supports VR and Hall Effect crank sensors. Can also modify ignition module pulse. Support both single ended and differential signals
• Supports most crank trigger patterns :60-2, 36-2, 36-1, multitooth, Nissan 350z, Honda 12+1, ignition modules and many more added frequently
• Boost cut option in Standalone mode
• Fully customized rev limiter in Standalone mode
• Closed loop (PID) boost controller, RPM/VSS/TPS dependent
• Parametric output (for nitrous, VTEC, water injection etc)
• Eliminates MAF (speed density conversion) with advanced learning algorithm
• Launch Control with drag-style antilag
• Road dyno
• Closed loop lambda control in Standalone mode (using car’s stock lambda sensor)
• Speed density (MAP based) or AlphaN (TPS based) operation in Standalone mode
• Speed Limiter Removal
• USB communication
• 24 months warranty

PC Requirements:

• Windows 2000, XP, Vista, Windows 7, Windows 8
• Screen resolution of at least 1024x768 16bit
• CPU with a clock of at least 600MHz,
• USB port

Ultratech products should never be used on passenger cars on public streets. They are made for race cars operating in the controlled environment of raceways and dragstrips.
