a/f not logging in some colums

[smithgrinds]

thanks spunkster i'm on it

97 civic
p72 ecu with s300
b20vtec with gsr head, rs machine pistons so about 11.8:1cr
stock b16 cams
rc440 cc injectors
performerX intake manifold w/ 68mm throttlebody
3" intake with bpi velocity stack
SSR street sweeper and 2.5" exhaust

i seems to only log the a/f from columns 5-7 for some reason? even at idle?


- the calibration (as an attachment)
- a datalog of a problem (as an attachment)
- what sort of vehicle you have
- what sort of ECU you are using
- anything about the car which has been modified from stock which may affect the ECU (don't include what sort of rims you have nor stereo etc).
- a specific description of the problem

so i thought maybe i accidently bent the valves or something but i just did a compression test
between 240-255psi in each cylinder? hmm

and idle is at 10:1a/f for some reason, it's kinda messed up :(

i figured it out, i was getting a vacuum leak from the throttlebody gasket.
i was wondering when i start the car why is the map sensor showing 1000+mbar
after i fixed that the engine is behaving a lot more consistant :)
