Hi Everyone,
Did this groove last night but could not post results untill now. Groove took longer than expected. Seems like Throttle Body material was resisting the cut. I did this groove as a favor for a friend that had a bad experience with HHO. Anyway, here's the results:
pre mod
HC 172 ppm
CO 0.01%
O2 0.5%
CO2 15.1%
NOx 1 ppm
AFR 14.16
Vehicle has 156,314 miles. Test was done at normal op temp. - don't have an exact reading. Outside temp. was about 50 degrees F
post mod
HC 34 ppm
CO 0.00%
O2 0.6%
CO2 14.7%
NOx 0 ppm
AFR 14.24
These readings were before capping off PCV, as I did not have right size cap. Anyways, I'll also log this in to MOD Report.
Happy Grooving!
