Couple of quick ECUControl Questions
 
My IAT value seems to stick. One day it was at 50, another day at 64. Do you think my sensor is bad or something?

My TPS - lowest it goes is 11. Does that necessarily mean my TPS needs to be adjusted.

How can I log my damn wideband with this? I'm assuming I'll program my LM-1 to output 0-1 and then use that as the o2 input for the ECU, right? Then at that point, i've got to do math to tell which values are which A/F ratios or something?

In other news - im sick of not having an Ostrich so I'm gonna have to break down and buy one.

Edit: ODBO PM6 ECU

Figured out the TPS thing - it was putting out .7v at idle. still need answers on the IAT, wideband stuff but in the meantime I will try searching PGMFI.org some more

i run my lc-1 at 0.1v @ 0.5 Lambda and 3.5v @ 1.5 Lambda (i think)...
as far as your iat temp...it doesnt change around rapidly...was it 50* out one day and 64* the next or are the temps just completely wrong?

50 one day and 64 the next. thats with the car running. I tried holding the throttle for a few seconds to see if that would make it change, but it didnt :(

it probably wont change...my iats dont change around much at all whether im idling or wot....

what i meant was...what was the outside air temperature when you noticed your iat readings...was it around those temperatures? or are the ait temperatures just obviously completely wrong?
