Description
IDEAL FOR:
- Fuel switching (eg: Race with Alcohol / flush running with petrol)
- Quick back to back calibration trials.
- Sharing an ECU between two vehicles or swapping engines, without the need to connect a laptop recalibration.
NOTE:
- Basic fuel delivery and ignition timing calibration switching response time is < 20 mSEC. ECU configuration switching (eg:- Crank & Cam Trigger method, Injector & ignition O/P configuration) response time is < 1 SEC.
- When online to a PC, calibration switching must be confirmed by PC operator response before calibration interchange occurs.
- Dual calibration ECUs use Pin 39 (HSI 3 I/P) as the dedicated calibration selection switch. Therefore it is not avaliable as a speed or general purpose switch input.
