My 99 Vortech supercharged M Rdstr has been running for two (2) weeks now and tonight I was able to verify the air/fuel ratios. I am very pleased with NickG's software for being SPOT ON at 14.2 to 14.9 through steady-state cruising with dips down to the 12s under acceleration. Naturally, when you lift the throttle, the AFRs go pretty high but they settle back down as soon as the throttle is opened again.
The Innovate LM-1 wideband O2 analizer/data logger worked like a charm right out of the box. The only thing that could've made it better would be if BMW left a spare bung in the exhaust pipe! I went for a fifteen (15) minute ride and recorded the AFRs and then downloaded them onto my laptop for review. Couldn't be simpler.
Besides making another test on my own car, the next official use for the LM-1 will be around the end of November when I'll be testing my installation of the Eurosport Twinscrew supercharger on a NYC based S-52 M Coupe.

very nice welding job!
Randy, I ve see guys connect directly to the OBII port in cabin area to pull basicly everything thing that you would need as a tuner. ie Intake temp, water temp, fuel mixure. Looks like the system you have does the fuel mixure job at a Fraction of the cost.
Nice to know you got everything working property and the fuel mapped correctly. Did you have in stalling issues? And could you let us know how your dyno turns out.
So now since you installed the Votech Supercharger what do you think of the power improvement? A good factor to exspect for 6PSI boost is 40% increase in power which should put you at around 289rwhp.
