Hey peoples

Another day... Another issue with my car...

I own a 1993 R33 Skyline GTST with the RB25DET

Ok in the last 3 days, i've completely redone my interior and my engine, dropped it in, bolted everything back together, ran all new hoses etc etc. It looks mint. haha. Replaced all oils, coolant, power steering fluid, brake fluid, gearbox oil, bleed the brakes, everything.

Today was the day to kick it over 4 the first time. These were my problems:

Problem 1: kept blowing a fuse.

Reason: Z32 AFM was connected up wrong

Issue: Resolved...

Problem 2: Car wont kick over

Reason: The Apexi Power FC (with HC)

I tried it with the stock ecu, car kicked over fine, sounded great.

didn't drive, just let it purr.

I thought maybe that my apexi power fc and hc were stuffed, but they are brand new, so i plugged it into my mates r33 and it worked fine, but for wat ever reason i can't get it to kick over in mine.

My assumption is that its not get enough power to the power fc.

I read on an faq that some r33's for watever reason run half gauge wiring to the ecu

which is fine 4 the standard ecu, but not enough for the fc.

If theres anyone who has experienced similar problems like this, any help u could give would be massively

appreciated. Or better yet, if anyone is in melbourne and could offer a hand to help get it started that would be sensational.

If u would like to contact me via mobile, my number is 0419 15 45 15

Otherwise i usually jump onto sau at least once a day haha.

Thanks heaps everyone...

from the faq:

My car won't start when I plug in the PowerFC, but the stock ecu works fine

First when dealing with a new PowerFC install and the car does not start there are a few basics to check;

# Check the PowerFC to car loom connector

# Check the warning lights on the dash, do they come up?

# On the hand controller, goto ETC, SENSOR SW CHECK, are any sensors highlighted in black? (Shouldn't be)

# Make sure you disable the Boost Control Kit if you aren't using it

# Make sure you have the right airflow meter selected (if you have a non standard one)

# Make sure you have correct injector settings (if you have non standard ones)

# Check all fuses

# Listen for clicking relays

# Check for burning smells near the ECU and or inside the ECU

# Inspect the ECU itself for physical damage or burn marks (open it up)

Finally we have seen on a few skylines that the car works fine with the stock ecu but not the with PowerFC. It has been traced back to a missing fuse. The missing fuse is on the left side in the R33 GTST and its at position #7. According to the diagram it is Engine Control. Somehow the stock ecu works if this fuse is missing but the PowerFC doesn't

See the diagram here for "Engine Control" which is a 10AMP fuse.

use a multi-meter, find which side of ecu is low on voltage, run new power to the ecu from fuse box in engine bay - its on ign switch.

Im sure you can find the rb25 pinout on here some were.

altho I have a question,

Does the H/C display anything with just the ignition on, and does the lights on dash work?

Ok when the ecu was in my mates r33, the hc was fully functional

when it was in mine, the hc kinda froze with the apexi symbol on the screen

Not sure if that means anything, i cant get to the menu in my car

Mint, i tried this theory, was missing the fuse, now it kicks over.

hc works perfectly, car started.

The idoling was a bit crazy at first but the longer i leave it, it seems to be tuning itself.

its settling down and becoming calm

is it supposed to?

wat do i do know basically?

the problem you had and what to do once it starts it covered in the faq

read the install procedure in it. covers everything to do and what to check once it starts and idles as well, also covers the self learn idle procedure

Hey bud

i checked this, there was one thing highlight black

boost i think?

wat do i do about this.

the car seems to wanna stall now when i started it

the idle is all over the place

its in the faq, keep reading

i've been reading the faq, and attempting to follow it, but my car seems to stall everytime i try the self learning process.

i get to like 1 minute then it just dies, wtf? lol

am i better off just getting a dyno tuner to fix it

wat sort of price would i be looking at?

is the power fc boost control kit connected?

using different boost control?

turn off boost control in the power fc menu.

No there is a setting in the menu for the power fc's own boost control kit.

this needs to be turned off if your not using it. i beleive it will make the car stall. which it did when i put a power fc into my gti-r

just turned it off and it still stalls?

read the FAQ again, it covers why it may insta-stall each time.

make sure the AFM is set properly

you need to do the self idle learn procedure again and follow the instructions (again in the FAQ) and do the complete procedure, and don't short skip it. be sure to test it before you say "ok its done"

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
