i need help with the precision 1600cc injector scaling , latency. ive searched all around the forum for a couple hours, and all i can find is 1200cc info, can anyone help. thanks

Not that many people use a 1600 cc injector low impedance on an Evo because they drive like crap

Me too. Is there anyone out there that can tell me where to get the scale and latency on these pte 1600cc low dependent? Please if u not helping us then dont write nothing negative on this tread!!!!

Well, im not going to give up to find the latency for these injectors. I let u know if i find out anything for these injectors.

why not try and determine it yourself using the normal process?

have you tried the manufacturer?

have you considered using the 1200cc numbers and increasing them by 1/3 as a start and then do the scaling/latency process?

cheers

they are likely to be difficult to dial-in

but start with something like 1.08ms at 14 volts latency

set all cells in your fuel map above load 120 to 11.5:1 AFR

do a WOT pull on low boost - check your AFR

if lean, reduce your injector scaling
if rich, increase your injector scaling

repeat this until you get the scaling that gives the closest match to 11.5 ARF
when you have got the WOT fuel more or less matching what is in the fuel map, then start adjusting the latencys to get the fuel trims in check.

Remember, latency errors wont have much affect on WOT AFR, but injector scaling will have an affect on fuel trims.

You will probably have to repeat this a few times too. Good luck!

Thanks for helping. But still does anyone know where can i find the latency for these pte 1600cc injectors? Like what email or website i can ask them to send me a latency sheet

PTE just machine them to specs and can't help you with the information you need. Take merlin's advice and dial them in yourself using his "safe" starting point. If you find this proven approach too hard for you to do, then you are going to need professional help.
