Hit the dyno.....
Hit the dyno.....
I talked to the company that did the dyno and they said theat we are going to actually hook it up to a wideband, but i was curious......we hooked up a scanner to it and noticed that the ECU is pulling 20% fuel to maintain the 14/1 AF could this be that when it was tuned something was not done right? I also get DTC codes for long term injector trim rich "p0172" thats when it pulls the 20%....any ideas?
Umm.................... Its canned....for the mods i have now but i know.......its still a canned tune. Im trying to find someone down here that can tune bu tthe one guy i found flaked out on me.
Stoich...for the 2.0, actually any car to be exact is 14.7 to 1. The PCM on our cars will +/- fuel to maintin a round 14. This is why i asked how to eliminate the o2 readings because when the car a/f is at 12 the PCM thinks its rich "because of the o2 readings" so it throws a code and pulls the 20% fuel i mentioned earlier.
