using open loop hondata... can any sensors affect A/F?
I'm looking for a list of all sensors that the ecu reads to compensate or adjust A/F...
or does the hondata just use the fuel maps programed by my tuner in open loop?
I have an s100b and P72 ecu...
also, I chewd up the crank fluctuation sensor plug, but with the obd1 ecu is it even used? I have no cel codes.
sometimes the car idles funny and runs rich, usually it runs perfect, so I'm wondering if I could have a faulty sensor..? and thats why I need to know what sensors influence A/F...
Thanks!

if you are in open loop, it goes off of the map only. closed loop it goes off of the iat, map and o2. it is the same as cold start. in cold start it is in open loop.
PLEASE CORRECT ME IF I AM WRONG!
my civic runs in open loop i dont even have my o2 hooked up and it runs flawlessly.

Dustin, I just got your old voicemail, lol. I will call you tomorrow on my way to Daytona Beach. Anyway ... Torin has you running in open loop I would assume. The only thing I can think of is it only does it on startup due to cold start enrichment? Either that or the temperature there is changing/fluctuating quite a bit. Sorry it took me so long to get back to you. What can I say. I own two inline four cylinders. I'm slow

crank fluctuation sensor should not be used in obd1
as for closed vs open loop, most people stay in open loop with such large injectors esp if tuned on the rich side of things.
some hesitate too much in closed loop/open loop transition.
the new Romeditor 4 should allow better adjustment of iat adjustment which will help me out a lot because my prelude behaves quite erratically in temp changes
i'm planning on spending 2 hrs retuning my car tomorrow
