im trying to idle my 1000cc injectors. is there a magic voltage number i need to dial in to get my car to idle correctly? im using s300 for tuning. right now it reads like this....

stock inj 240
current inj 1000

volts 0.00 8.09 10.11 12.13 14.16 16.08 24.55
dead time(ms) 1.49 1.49 0.96 0.68 0.49 0.35 0.35

 

fuel trim
overall fuel trim -27%
cranking fuel trim -15%
throttle tip in trim 0

cold start
post start fuel adjustment -10%

 

On top of trimming from 240 to 1000 you're pulling out an extra 27% as well. That's probably part of the problem.

 

so should i trim it by less percentage or should i type in 800cc or something?

 

The overall will probably need to be a positive number. You take the full linear trim out by going from 240 to 1000 and since the injector takes longer to open it will usually run a little lean. Start at 0 for overall and dial it in. Tune it.
