ive got ca18det injectors with the ballast resistor and a z32 afm and a r33 turbo with bosch 040 fuel pump....will my apexi safely support these mod's??

please speak from experience!!!

does any1 know???

what size are ca18det injectors. with a safc you dont want to have to take out too much fuel otherwise it indirectly stuffs with your timing. and yes, a safc will support a z32 afm. you just set it up so the safc knows its getting a signal from a z32 and sending it to a r32 gtst ecu.

the injectors are 370cc...enough for 200rwkw???

i thought stock R33 GTST injectors were 370cc? and my power FC reported 100% injector duty off 14PSI boost, stock turbo, intercooler etc.. with the base FC map.. so i doubt they will support up to 200RWKW.

safc will run the 370cc injectors, it will run the Z32 afm, it will run a fuel pressure regulator and a 040 fuel pump, it'll even run with a highflow turbo. speaking from experience. daily driver. 190rwkw. upgradding to PowerFc as soon as I book it in.

a sitc would help for the ignition timing adjustments.... BUT if you have a R32 Id personally get a remap (contact username: Yoshi) and still use the safc for minor corrections.

wats a sitc??? and how do i get incontact with yoshi??? is he located in sydney??

also how come your upgrading to a power fc if your apexi safc is doing a "good" job?? or isnt it!

sitc is an apexi Super ignition Timing Controller

adjusts the ignition timing, like the safc adjusts the air;fuel ratio

google is your friend

Ive been using safc/sitc for 2yrs. thought its time to "trial" a PowerFc with my auto box

fact is a full aftermarket ecu will always be a better choice than a piggyback.

Yoshi does remaps, have no idea where he is. pm him.

yes - my safc has done an awesome job. just noticed tho that you are talking about a SAFC1. bugger that, get the SAFCII or the SAFC Neo.

As I mentioned in a PM.

Using a Z32 with the SAFC is 100% pointless as the SAFC bends the voltage back to what it would have been with the stock afm.

As a result if the stock afm were maxed out yet the Z32 is outputting say 4volts. The safc will increase the voltage back to the maxed 5.1volts so the ecu against see's 5.1volts as it did with the stock afm.

Stick with the stock afm, stock injectors and a nismo fpr in your case.

IF you were to have the ecu remapped with a high flow then do consider the Z32 and ca18det or gtr injectors.

      I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.

      S1 rb25/s14 starting problem

      By GTSBoy · Posted

      Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
