Sprint 500 20V 4AGE

Postby Gramacosport » Sat Feb 17, 2018 5:36 pm

I am wiring the Haltech Sprint 500 to a 20V
questions and recommendations

Does the Oxygen OEM sensor works fine as input to feedback the ECU, or its a must to a wideband sensor.

20V 4age, idle valve its a bipolar, as far as I understand you could connect one DPO to one side of the idle valve, any feedback on that, and recommendations for the setting of this DPO.

the Tach out line, I want to use the AE86 OEM Tach, could I used it directly or do I need any type of converter

OEM O2 sensor is narrow band and most likely does not work correctly anymore given the age of the engine. You could use it if it works for cruising, but not for engine tuning under power.

PS500 only does open loop idle and does not support 3-wire types. You would connect one output to the side that closes the valve, set as BAC Main, and invert the signal. This will give you some control but only half.

You would either use a converter or get the signal from a coil -ve terminal.
