Not Ranked
Hello Mikey,
Although I do not have experience with the Dax exhaust systems I do run injection with 02 sensors (dual in my case) located in the collectors. I experienced false 02 sensor readings. They were linear but were showing my mixture was much richer than it really was. My target display was 55 units to equal stoichiometric but I was seeing 68 units
I moved the 02 sensor closer to the head or placed it in a single rear header tube without any other changes and my display dropped from 68 to 56. The collector has cooler E. gasses so skewed readings but testing showed a predictable amount. Your system may not care but keep this in mind.
You will love the injection over a carb. It does need to be tweaked to your application but once dialed in nothing more needs to be done for instant hot or cold starts and a very snappy response. ENJOY !!!
PS... if not willing to learn every nuance of this system to do your own tweaking do not settle for less then perfect and take it to Tunner !!!!!
