Injector cleaning

[Alchemis]

guys/girls,

anyplaces around here provides Injector Balancing and flow rate test ?

i'm wondering if the numbers are true that my injector can provide air fuel ratio 8 with a remapped ECU.....

stock ECU on my car does not give that high. only aorund air fuel 12.

last resort... ditch my ECU..... get powerFC.... give me some ideas first.. :)

You already set yourself a target >>>> POWER FC!!!!!

i wish i have the budget to buy immediately.....

money already allocated for other plans... need to plan for it :)

i answered your q's on the rx7 forum. I'll just chime in here as well. I seriously doubt you're running 8.1 afr's. At such rich mixture you're going to have ecxtreme bogging and most probably very high i.d.c's. I have tried to work around 11.5 afr'z on my idle map on the pfc (fields p1n1-p4n6) 1000-1400rpm and it already starts to missfire. What is your baseline fuel pressure? What is your idle afr's?

Get the power fc once and for all.

serious.... air fuel 8.1.....
i have ALOT of misfiring when it's still not fully warmmed up yet....
engine dragging from 7000 RPM somtimes gives me.... like those initial D Evo 3 misfiring system. .bahahahha it bangs every second until lower RPM...

my idle is air fuel 11 :)
and then 1500 onward till 3500 still acceptable air fuel 12.. but it's up and down...
and then 3500 onwards the graph declines severely... until it hits 8 at around 7000 rpm.

maybe the ECU is for single turbo.....i'll need to double check with stock ECU if my injectors are fine or not.... once that's confirmed my injectors are working perfectly... then i'll go for PFC.... where to tune it ? ehhehehehe or i stick with the stock PFC mapping ?

the quesiton will be who can tune FD push the most out of it when it's boosting... low load ones not really matter.. as long as it's safe afr to prevent engine blow.... :)
