Note- sample rate was down as was getting quite a few comms errors for some reason

 

[DPJ]

Better MAF readings, but still throwing some correction factors. The change in value in 032 long term fuel trims concerns me slightly.

Have you cleared fault codes recently? If not, could you do so, then relog again?

 

[Cowie]

Dave,re-run these logs or are there others that will give any better/extra info?

 

[DPJ]

Rerun 003+020 and 118 +032 please.

 

[Cowie]

ok mate will do,aside from those,have just serviced the DV and put a yellow spring in,should i see any difference there?
from the logs i've done am i able to work out what boost it is running? bar/psi? if so is there a calc i need to convert?

 

[Cowie]

Right Dave,here's run's i've just completed,

[DPJ]

Ok, that's acceptable now, CFs are not excessive. Long term fuel trims no longer showing a fluctuation. I'd be interested to hear P-Torques's opinion on your logs - fancy pming Will?

In answer to your boost question, take your fifth column in 115 log and subtract 1000. That gives your boost in millibars.

 

[Cowie]

Yea,will do Dave,do you think there are any issues?
do they look ok for a stage 1 mapped LC?
about 14 psi then,is that right

 

[james walker]

maf reading still a little low... mine peaks at around 175g/s same map as yours.

 

[Cowie]

Is a new MAF mate,gonna change panel filter,thats been in a while but looks ok
thought might have been better readings esp with the bigger air feed
