Hey guys, I did some searching around and wasn’t really able to find any non-dated/useful information. I’m pretty new with wiring and electrical stuff on these RB’s, so give me some slack.

Anyways, I’m in the market for a Power FC for my RB25DET, and I’m kinda just trying to see if the Power FC is the one for me. I know there’s plenty of monitoring you can do on your hand controller (boost, coolant temp, etc.), but could someone write a list of everything there is that you can monitor?

I’m also interested in a multifunction-like gauge. Basically, I want to see speed, tach, water temp, etc. (the basic stuff), and I want it to be in a small gauge pod so it can be just mounted to the dash or whatever.

Thanks guys!

I disagree, PowerFC with Handcontroller  ($800-1000) will show everything OP requested plus much more (ecu inputs status, ability to set basic parameters, and even full tune if really necessary) for less than half the price of a haltech/link etc with dash.

I've just replaced the PFC with a Link in the stagea and miss the hand controller, am looking at adding OBD port and OBD display to the Link but everything is more $$$ to do what the PFC already did. Yes they are more capable ECUs but for a standard or lightly modified car PFC have been doing the job perfectly for decades.

Agreed with the above.

There are definitely more complex ecu's out there with more features but for your basic mod's PFC is a decent choice.

Heck, I'm still using mine 12 years on and local tuners can still use them too.

I’m going with a Garrett GT3076R, 3 inch exhaust, probably 750cc injectors, top mount manifold, Walbro 255, and TiAL BOV and wastegate. Would a Power FC be good for this setup?

It will work fine, as long as you are still running the air flow meter of course. Having a BOV connected will help prevent stalling when the throttle shuts suddenly which can be hard to tune for with an AFM

That was pretty similar to what I had been running for years on a PFC before I went a little sillier on the new engine...

Yep you'll be fine.

Only minor issue you MAY have is air flow reversion back through the AFM causing a slight stall. With a decent length intake pipe and a good tuner you'll be fine.

 

 

 

 

I believe the stock ECU, therefore the powerFC can only monitor:

Ign Map

Inj Map

AirFlow

Injector

Boost

Acceler.

Ign/Inj

Cranking

Wtr Temp

Rev/Idle

 

So the big ones missing would be Oil Temp and Oil pressure, i think you can add them as analogue inputs, expect that to add around $300 to the cost for good quality sensors.

 

Also AFR would not be shown, again i think about $80 for a half decent one? Also not sure how many, if any, analogue inputs are in the PowerFC.

If it was me i would get a haltech or even adaptronic modular ecu.

They both have can bus and means you can then run something like this https://www.powertunedigital.com/ and pop it in a R34 MFD hood

would still need oil temp, pressure and afr sensors though.

 

I have an adaptronic select and that has limited me a bit so i had to get a Race Technologies Dash 2 Pro (which includes logging for track work) along with the oil temp, pressure and afr sensors and will be mounting it in the GTR MFD hood.

Well something more modern like a Haltech is something I’ll look into. But basically, I want a good and reliable ECU that call also plug into a screen to read vehicle speed, fuel level, coolant temp, etc.

The cost of a PFC is good, but if there are better options for more money, I’d rather just spend the money.

So say I want to look into something more modern/better. What’s a better ECU? Also, it’s an RB25 240SX

No, because you're planning to run an atmospheric BOV.

Also why a GT3076? Man it's 2020 not 2006.

Won’t be able to get fuel level or speed without running your own sensor. 

 

As said before the car can only show the below. Anything additional will require you to add your own sensors to the new ECU or Dash

Ign Map

Inj Map

AirFlow

Injector

Boost

Acceler.

Ign/Inj

Cranking

Wtr Temp

Rev/Idle

    • I know why it happened and I’m embarrassed to say but I was testing the polarity of one of the led bulb to see which side was positive with a 12v battery and that’s when it decided to fry hoping I didn’t damage anything else
    • I came here to note that is a zener diode too base on the info there. Based on that, I'd also be suspicious that replacing it, and it's likely to do the same. A lot of use cases will see it used as either voltage protection, or to create a cheap but relatively stable fixed voltage supply. That would mean it has seen more voltage than it should, and has gone into voltage melt down. If there is something else in the circuit dumping out higher than it should voltages, that needs to be found too. It's quite likely they're trying to use the Zener to limit the voltage that is hitting through to the transistor beside it, so what ever goes to the zener is likely a signal, and they're using the transistor in that circuit to amplify it. Especially as it seems they've also got a capacitor across the zener. Looks like there is meant to be something "noisy" to that zener, and what ever it was, had a melt down. Looking at that picture, it also looks like there's some solder joints that really need redoing, and it might be worth having the whole board properly inspected.  Unfortunately, without being able to stick a multimeter on it, and start tracing it all out, I'm pretty much at a loss now to help. I don't even believe I have a climate control board from an R33 around here to pull apart and see if any of the circuit appears similar to give some ideas.
    • Nah - but you won't find anything on dismantling the seats in any such thing anyway.
    • Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.
    • Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.
