Man if its only temporary, i'd suggest an APEXI SAFC.....Yes yes i know they are old tech but they work very well for stock/mild cars and are mega cheap these days. $100 for an SAFC and $150 to tune it you could run your highflow and even up the boost a tad, then when you get some extra cash you can always get your money back for the SAFC. Just a thought.

This could be read as it is safe to run 22psi on the stock ecu with a highflow, which is very wrong.

Please fix your post so we keep everything accurate.

What is the correct maximum amount of boost you have safely run on a stock ECU with a highflow?

yep thats how i read it

how would the car perform with the highflow turbo and no tune?

I will post a photo of my turbo for more understanding haha

why highlow, just get rebuilt turbo....with wheels that dont self destruct

Old turbo died and took out motor... coin spent on new motor, ideally wants more power, but doesnt want to spend more money... hmmmmmmm

I would rather spend $900 on a cheap nistune + tune than getting a different turbo for "reliability".

This sounds like good advice.

no nistune option is cheap for an r33....if you dont know this already you do now, so you can stop giving crappy advice :P

SAFC can only bend the AFRs, however it does not change timing.. if you look at the stock R33 map, timing values are around 22 on noise, which is heaps if you decent to add in more boost.

Like I said, best option is a Toshi remap.. happy days pump nearly 1 bar into motor no knock, and happy AFRs

oh ok. thought it'd just be like a daughter board or something... pulsar ftw

The SAFC doesn't bend AFR's, it bends the Airflow meter signal, which in turn causes the ECU to reference different cells(Fuel AND Timing) than it would without the AFC.....plus i only recommended it as a cheap alternative till he sorts out a proper ECU ;)

Yeah I know what you mean, I just said AFR because bending the AFM signals causes the AFRs to change.

However you do realise that will cause the ECU to reference cells with less load = more timing right?

Ofcourse, however in the last few 33's i've installed these into drive great and do not ping at 11-12PSI(11.5-ish AFR)

its all good! going R + R is good motivation to get the ECU upgraded.

I admit making an mistake quoting the maximum boost level safe to run on stock ecu earlier. Been corrected and that it should be no higher then 10psi.

Reason of having the high flow, as cost wise is similar or cheaper then to rebuild, similar drive ability working with factory ecu, making good power when other supporting mods are present, and proven by time to last.

For a budget ECU upgrade you can get Toshi to remap based on factory injectors and AFM. I've personally sent few customers that direction and worked well.

    • Ah right. Maybe my rb just loves chewing through batteries lol.
    • On the R34 can't you just unplug the IACV? This is the way I've always done it on the R33. Disconnect IACV, get it idling around 650rpm, and then do a power reset on the ECU to get it to relearn idle (factory ECU).   The big reason no one has touched on as to why you'd want to get the base idle right, is that it means the computer needs to make smaller adjustments to get a good idle at 700-750rpm.   Also, cleaning the IACV won't normally make the car suddenly idle lower or higher. The main issue with the IACV gumming up is that the valve sticks. This means the inputs the ECU gives, aren't translating to changes in air flow. This can cause idle choppy ness as the ECU is now needing to give a lot of input to get movement, but then it moves too far, and then has to do the same in reverse, and it can mean the ECU can't catch stalls quickly either.
    • 12.8 for a great condition, fully charged battery. If the battery will only ever properly charge to about 12.2V, the battery is well worn, and will be dead soon. When I say properly charge, I mean disconnect it from the car, charge it to its max, and then put your multimeter on it, and see what it reads about an hour later. Dieing batteries will hold a higher "surface charge", but the minutest load, even from just a multimeter (which in the scheme of things is considered totally irrelevant, especially at this level) will be enough over an hour to make the surface charge disappear.   I spend wayyy too much time analysing battery voltages for customers when they whinge that our equipment (telematics device) is causing their battery to drain all the time. Nearly every case I can call it within about 2 months of when the battery will be completely dead. Our bigger customers don't even debate it with me any more ha ha ha. A battery at 12.4 to 12.6 I'd still be happy enough with. However, there's a lot of things that can cause a parasitic draw in a car, first of which is alarms and immobilisers. To start checking, put your multimeter into amps, (and then connect it properly) and measure your power draw with everything off. Typical car battery is about 40aH. Realistically, you'll get about half this before the car won't start. So a 100mA power drain will see you pretty much near unstartable in 8 days.
    • Car should sit at 12.2 or more, maybe 12.6 or 12.7 when fully charged and happy. If there is a decent enough parasitic load then it will certainly go lower than 12.2 with time. You can't beat physics.
    • Ok guess I can rule out the battery, probably even the starter and alternator (maybe) as well. I'm gonna clean those leads and see what happens if it's still shit I might take it to an auto electrician. Unless the immobiliser is that f**king heavy, but it shouldn't be.  If I start the car every day, starts up perfectly never an issue. Isn't 12v low, shouldn't it be around 12.5v?
