So I have a nitrous outlet 78mm plate nitrous system along with the nano. I also purchased the nitrous outlet progressive controller, harris speed interface air to fuel controller, and the lingenfelter timing controller. So I've decided to go with the harris over the lingenfelter. Now, reading over the install instructions on the harris and the progressive controller. I'm thinking I can install both together in order to use the progressive of course and allow the harris speed controller to control my tune when I use nitrous. This way I dont have to load two seperate tunes when I want a N/A tune and a nitrous tune. I can instead arm the nitrous system and the harris controller will do its thing for nitrous. Now, I'm curious if anyone has done this before or any input on me attempting to do this? Any input is much appreciated. Thanks.
