Cool thanks. I just found this on bout the aem:
"This system is offered in both single and dual channel modes and is the most affordable UEGO controller available. The AEM wideband UEGO controller has a very low current draw and features both 0-5v and 0-1v calibrated outputs to mimic the factory narrow-band sensor, eliminating the chance of a factory computer issuing a trouble code."
So I can use just the aem wideband and hook it up to the js monitor and get accurate results on the bar meter, right, or any other a/f meter for that matter?I wanna use the js meter because it's got actual numbers rather than a sweeping meter. What's the difference between the single and dual modes? I've got a 2k gsr but im converting to obd1 using a p72. Is it tru that with obd1 i only need one o2 sensor? can it be the aem one alone? If so which o2 sensor should i get rid of when i get my header and exhaust upgraded?

I've got more to ask. What would be the easiest way to get the wideband reading datalogged. Is there some setup like the one i had in my high school physics lab in which i could log realtime a/f results x rpm, with the a/f represented as voltage and/or a/f. how would i go bout setting it up. I know bout hondata and aem, but im on a mad budget and looking for the cheapest way possible. Is there some sort of datalogging program that i could download and a cable or two to get the info i want on my computer? remember cheap. thanks
