every setup is different

YOU have to find it. it is EASY to find.

its dealing with different battery voltages.

get to where your tune is consistant, as in you can dial in the AFR's and get similar or same results all day.


make sure everything is off. no radio, no headlights, no wipers, nothing.
log your AFR's.

go ahead, turn EVERYTHING on. no need for massive stereo. just load the alternator and battery with stuff that you can still drive with for a while.

log AFR's. adjust the injector dead time until you can match up the AFR's

once you have matched AFR's, turn everything off, and redo the process until your numbers are staying similar.

BAM

NEVER use other peoples dead time results.


EVERY CAR SETUP IS DIFFERENT EVEN WITH SAME PARTS/TUNING SOFTWARE/LOCATION.

many thanks for the reply.
I have a problem with the injectors. with the original dead time values from Hondata s300, my car stuttered over 2000 1/s at partial and full load; and afr is down to under 10. we tuned and tuned but the problem dont go away.

I've found dead values ​​time and have entered it. when the car was cold it has not stuttered .. But when I went some miles it has started again. Now I would like to know if the injectors are broken or if the problem is when the dead time values are mistake.

i hope for help :)

try turning off ALL fuel enhancers/enrichments, and dial in AFRs.

no idle helper, no coolant temp enrichment, no air intake enrichment.


all you need to do is make sure the motor is fully warmed up, as in 30+ minutes of operation.

report back.

dead times alone dont fix or create stutter. they can, but usually not by themselves
