Would there be an issue with running 2 EMS systems, like using the E6K and also running the Greddy E manage system?

YES!



The e-manage piggybacks off the stock ecu doesn't it?



You could use 2 ecu's if they do different things i.e. run a TEC II ignition and a SDS fuel computer.



But the Haltech does both ignition and fuel, and so does the e-manage.

So does TEC II https://www.nopistons.com/forums/pub...DIR#>/wink.png
