Injector Question With Power Fc

[hectic32]

hey all jus got a tune the other day on my r32 gtst rb20det with power fc fuel pump r33 turbo and ya other basic mods boost controller etc. was aiming to run 14 psi but had to cut back to 13 psi cos my standard injectors maxed out and made 241.6 hp atw so now got to put gtr injectors in and go retune it but want to know how to adjust the fuel mixtures on the pfc when i put the injectos in so it won't run as bad so i can drive it to the dyno. So all im askin is can i do a small adjustment on the power fc so i can get to the dyno with no problems hope that makes sense thanks

Need to enter the injector correction and new latency into the PFC so you work it out as shown below

Old SIZE / New Size = Correction

260cc / 444cc = 58.558%

New Latency - Old Latency = Latency Correction

0.772msec - 0.89ms = -0.118

Then to enter the values you do the following

so for the first value that's displayed in % you enter/select down till you get to 58.55% then the 2nd list which show's the correction you select down again as the value is negative till you get to -0.11 ( I think it rounds it off to the closest decimal so being 0.118 you might be forced to select 0.12 - can't remember off the top of my head but you'll see when you do it)

thanks heaps for that didn't think any one would have explained and showed me how to do it that good so once i've done this it should be rite to drive to the dyno yeah?

Yep will be fine to drive to the tuners, mine ran like stock but a little richer than normal.

No harm done there though

Have fun

should run on gtr injectors, SR's will run fine going from 370 - 550cc on std ecu.... enough to get to tuner anyways.

Yep, when I drove my R32 to you Trent, it was running standard RB20 map on the PFC with the GTR injectors and correction done on the PFC and z32 AFM. You should have no problems man
