Rich N Retard

[skitzone80b]

Oh yeah, another rich n retard thread.... Mate reckons it's pretty usual on a s1 25 with stock management if you gas it to hard. But I don't quiete believe him my coilpack or afm are gone aren't they? At full wrap it hits 5 grand and then feels like pushing it to keep it revving.

I've heard a lot of people and there ideas on why it does n what's causing it. But so I don't spend to much money apart from throwing a brand new afm on ( I have 3 afm's and I'm running what one felt the best) or putting splitfires on it is there a way to actually test what's causing it to hit limp mode?

Um, let's just say it would be best you if actually provided some information to let people work out if they think it's electric or if it's R&R. Boost level for instance. Dyno'd? etc.

Sounds exactly like my S1 Rb25 before retune. It wasnt misfiring it just lost torque @ about 4500-5000 rpm,

Got it stock and was like this. SO started changing parts to see what was the problem

3inch turbo back exhaust- same

FMIC- same

Splitfires- same

EBC@ 10psi- same

retune- brought to life. Perfect motor, just a conservative S1 computer.

Not sure how you find it out without actually getting a computer and a tune. Perhaps call around the reputable shops near you. Probably plugging in a diagnostic program via consult cable should be able to tell you some things. Prob see the timing getting pulled out of it...

Not saying it is certainly this on yours but its possible. Check all the bits first.

^^Tune? What was tuned on the stock ecu?

[GTSBoy]

It's pretty clear he moved to a Z32/R32 ECU.

[Hanaldo]

How's that clear? Has he mentioned something in another thread? Reading this thread it sounds stock?

What makes you think your mate is wrong?

[skitzone80b]

My motor is completely stock I don't know who you're saying has a z32 afm and rb20 computer but not me, not anymore. The afm's hitting 4.67 volts if you just jump on the throttle hitting around 4700-5000 and it just takes for ever to rev as it is pulling timing. I have had the data logger on it and I know for a fact that it's pulling timing when this happens. If you take it to 4-4500 and slowly wind the pedal in she'll pull to 7 quiete easily. I have a boost bleed that is set at 8 pounds and is not creeping. And when it gets hot the idle got crappy and stalled a few times at lights on the way home today, I did like 180kms on it was fine til the halfway point when i stopped in at a mates when I left his it'd start catch stall til I gave it a little rev. I think it's the afm personally but I asked the question so I could get other peoples opinions.

I just don't understand how a factory built and tuned motor can't go full throttle over 5 it sounds fricking stupid to me, plus a mate has a s1 33 and before he went adaptronic it didn't seem to do it in his!

[GTSBoy]

Because, in the same post he said "Not sure how you find it out without actually getting a computer and a tune". So that looks to me like he knows that tuning an R33 involves getting a different ECU.

Oh yeah, I thought you were talking about my car...

[Hanaldo]

Ohhhhhhhhhh so did I lol.

OP, assuming you have a stock turbo, 8 psi SHOULD be fine, but where are you getting that reading from? It's a bit hit and miss with R&R, some ECU's do it lower than others and some are fine running much higher boost, so it's definitely still possible that it's R&R.

[JonnoHR31]

Does it feel like this?

If so, lower the boost a bit and see if it goes away.

If it's misfiring then it'll be coilpacks or plugs.

[GTSBoy]

Clear?

Yuh, clear, as per the next line of his same post that I've already quoted above.

[skitzone80b]

This car sat in a shop for 4 months having all the electrics replaced brennan stay off my threads don't wanna hear it.

Yeah that's exactly what it looks like! But if you slowly bring it upto about 4 you can then gun it and it'll pull to 7.5

Stoopid r33 ecu's are stoopid.

Worst ecu made, some are ok.

Go aftermarket

[jjman]

haha, yeah its a nistuned Z32 ecu.

Probably only clear to people who know about these cars and the untunability of the R33 ecu.

yeah it is a crack up how poorly the stocker goes. If it wasnt for the compression test i did (175-176 across all 6) i would have thought something was wrong with the motor. But doing a bit of research on the issue on threads like this i worked out it should be just a lame ecu.

Which all things being equal was a good thing for me as it mean that this 17yr old car had never been able to be pushed hard.

Cant imagine how someone would have bought it from the factory like that and tolerated it. If i bought a brand new GTST n it made power like that i would have put it back through the dealership door kamikazi style...

[JonnoHR31]

It only happens when you modify it and raise the airflow higher than standard, it'll never happen with a 100% standard car, which is the way Nissan wanted it.

OP, lower the boost a bit and it should go away.
