some more logs

[Cowie]

just run a couple of logs to see how cars adapting with the FMIC,and after a couple of tanks with the octane booster with the BP ultimate

CF's look better

fuel trim has gone from -10.9 to 0 is that good or has something broke/failed?

FMIC working well ,intake temps from 50 down to 27

 

[DPJ]

Looks better.

You have zeros in 032 because you've either reset your throttle body or cleared a fault code?

Best not to log blocks like 020 and 032 together because neither of them show rpm. (That's why I suggest 003 and 020 115 and 031 118 and 032. In each pair, the second block doesn't show rpm.

 

[Cowie]

Dave,thanks for that mate,had a run out to newcastle yesterday,and the car had a bit of stuttering,I am just waiting for all the bits to come for my leak tester,think there is a leak as when i plant the foot its then when it feels hesistant,off boost its fine,am i heading in the right direction or could this still be maf related?

 

[DPJ]

Have you tried cleaning your throttle body? The stutter under load could possibly be a coil pack starting to fail. Could be Maf related...

 

[Cowie]

throttle body has been cleaned Dave,think I'm gonna get 4 new coil packs,are the hitachi bolt down ones the preferred choice?

If i could get hold of another MAF to try,should I see/feel instantly if stuttering has gone,what i mean is car doesnt need to get used to new maf?

Stuttering should go striaght away. How many miles have your coilpacks done?

 

[Cowie]

Stuttering should go striaght away. How many miles have your coilpacks done?

Have changed them all over last 4 years Dave, last one went a couple of weeks ago,prior to that I'd guess,10,000 miles previous

what's the usual life expectancy of a coilpack?

 

[LEE69]

Mine were on the car when i got it and have done over 16,000 with no coil pack problems.

 

[Cowie]

i've done just over 60,000 in 4 years Lee,all have been changed at some point.

 

[Cowie]

Done some logs this morning

what's the usual life expectancy of a coilpack?

Somewhere around 30k - 35 k miles I reckon.

Something not right there. I don't like the way the Maf readings are fluctuating up and down as they climb up the range. The ecu is compensating hard for it running rich. Note at around 3500 - 3700 rpm actual is a bit off requested boost. I think I'd double my efforts to find a boost leak first.
