Emerald ,all day long.
The new emerald has Al and LC, and these can be added FREE to existing ones via a few parts and software download.
They are DESIGNED by EMERALD so they do know the system inside out.
You can use any type/make of sensor, they have SELF CALIBRATION for some sensors, can run closed loop, be mapped on the TPS alone if needed, and have INDIVIDUAL CYLINDER TIMING AND FUELLING, if necessary.
Karl the boffin who designed the ecu is an awsomely clever bloke, they really do look after thier customers users of their systems.
FULL mapping is £280 however loing it takes.
Can run semi, sequential, or batch fired, turbo or NA, has triple maps, with interpolation.
