A little background. I bought my motor used and besides not knowing how well it was tuned to start with, I changed out the 4 into 1 headers with a set of Chris Foley's 4-2-1s.. Sometimes I get pops & flames out the exhaust on decel so I'd like to see if my Webers are jetted right.
I don't have easy access to a chassis dyno and am considering a wideband Air/Fuel Ratio Gauge so I can log and monitor the data at the track. Again, I'm curious how my normal AFR is with just my Phase 9 (sometimes I'm getting pops & flames out the exhaust on decel) and also what happens to my AFR when I add my supertrapp onto the Phase 9 for <=90db tracks, etc. (This usually eliminates the pops & flames) I could make a long tow to a chassis dyno somewhere but I'm thinking the gauge might be more helpful longterm to have ongoing access to the data.. Anyone use one of these? (IMG:http://www.autometer.com/img/products/4378_d.jpg) AutoMeter or one of these? (IMG:http://shop.airfuelratio.com/images/product_1_zm.jpg) NGK I know there are lots of other brands out there too (AEM, etc.) Anyone get good enough data for tuning purposes? Or should I just go find a chassis dyno? Thanks in advance for any feedback on your experiences |

I have an open spot on my gauge console where an unused leftover gauge from my car's aircooled days (head cyl temp gauge) still lives.
I was thinking of replacing it with one of these air fuel ratio gauges: K&N or C.B. Performance I am leaning heavily towards the CB Performance one because it fits better with the existing VDO gauges. Also has the benefit of costing less than the K&N. The only problem is having to weld the nut on the exhaust for the O2 sensor. gotta find someone with a welder to do that since mine is long gone. Is it worth getting a 3 wire heated sensor? Seems like the single wire is fine, just make sure it's warmed up before doing any tuning. For carbed cars, this seems like a really nice gauge to have, esp. for the $80 or so that it costs. Seems like it would be really useful for tuning, and making sure things are running right. |
