More boost is on the to-do list. How much do you guys think I can push safely on a stock block?
GTR, do you have a consult device?
You can use one to see if your O2 sensor is working properly. It's supposed to be at 0V in lean conditions and 1V in rich conditions.
I should probably check mine.
No I sure don't. I need to get one though. Changed out the o2 sensor today, but checked the voltage before I installed the new one. Thought the sensor wasn't getting any power, it was only reading 0.1-0.2 volts when running. Later read that they don't use much power at all.
The new sensor has my cruise AFR's looking a ton better. Just made my 45mi trip to work, it was between 14:1-14:9 the whole way. It had occasional dips down to 13:1 and same up to 16:1, but it's way better than a constant 12-13:1.
That old sensor was more than likely the original sensor (20 yrs old now!) and when I first went ka-t with that junk emance tune, it idled 9-10:1 for a good while til I got a real tuner involved. It def needed a new sensor.
What's a good place to get a consult cable these days?
