how to use vcm to scan for a bad spark plug/ wire or coil?
i am not sure if that is normal for STFT to switch constantly from positive to negative values anywhere under WOT.
my car has a cam and breathers without PCV.
please, advise.
its an 09 ctsv with swapped engine and stock tank and pump,,
fuel level was right in the middle,,
why is it common in swapped cars?
my car sometimes exhibits a very weird issue,, i couldn't even log it,,
after a sharp quick turn to the right,, it hesitates just like a fuel cut off or a misfire only for a moment and then drives...
pm sent,, thanks,,
here you go
i tested 2 ls2/ls3 tbodies and both jammed at wot and forced car into limp mode
a friend just did a full LS3 swap on his C5,, all seems fine except for LS3 tbody as it jamms almost on each WOT,,
any considerations to ba taken with the tune to prevent this?
i have replaced my old 08 ls3 tbody with ported ls7 tbody and car couldn't even start/idle,, is that expected since both tbodies are almost of same size?
i have already jammed airflow table by 30%,,...
the two histograms are not supported in latest vcm scanner,, car is 09 ctsv,,
any newer versions of this config available?
anyone please,,
a friend just did LS1 to his 08 avalanche,, what to disable/enable in tune to have running properly?
how to disable DoD?
thanks,,
please, look at the attached log,,
you will see TCM is applying max pressure (290.x) to 3-5-R rapidly while gear is still in 2nd,, this only happens at the very first time car goes in 2nd after each...
here is the tune,,
can you share the recommended config to log idle?
i couldn't get an LS1 holden with MS4 cam to idle until i plugged out map,, reduced fuel to leanest possible,, jacked up base airflow and spark,, after all that,, car surges once on D,, and goes in...
anyone please
i spent the whole last night trying to idle tune my friend's holden to no avail,,
it idles few hundreds rpm above commanded in target idle speed,,
when i rev it in neutral, hold it steady and leave...
here is a log,,
as you can see,, TCM applied max line pressure (290.x psi) to 3-5-R few times in 2nd gear,, this what made the car barking,,
another thing,, no 3-4 shift time logged,, if my issue...
i am sold to stock clutches with extra plates for the next build,, but how many extra clutch/steel plates for each pack?
what clearance?
which 456 shaft replacement you got? where?
could it be the 4-5-6 piston?
hi all,,
i need your help and feedback,,
it all started since i rebuilt my 6L90,, only replaced clutch packs (alto for 4-5-6 and 3-5-R),, pistons,, seals and filter,,
i tuned it as per the...
how to edit rpm scaling in the scan config file?
does this work with 09 CTSV with E67?
i opened the config file and found histograms 10 and 11 unsupported,, any work around?
car is an A6 and has a cam of -5 overlap,, idles good except for 100rpm...
what if i wanted the stock convertor to never lock-up unless on 6th gear?
any harm?
i believe convertor locks up only to drop rpm for better fuel economy but slower throttle response and sluggish...
very interesting,,
if TM only pulls engine timing,, will this respectively reduce commanded shift pressure?
pulling timing will reduce engine torque which is what shifting pressure is based on,,
