Hey guys I am tossing up between either Apexi Power FC or NIStune, question is what model Power FC do I have to buy. I cant find a Stagea specific ones. looking around for a second hand one ( I know, I know but Im on a limited budget. ) Can some one please shed some light on which one I need to get if I choose the Power FC ? 2nd question is, If I buy the NIStune board myself, with the Board, Cable, Software, and Installation for $615 does that give me the ability to tune myself or just to "adjust" things ? How hard are they to self install and can the car be driven to the tuners ? Or will it have to be towed ?

Any help is greatly appreciated :-D . do

You will need a powerFC to suit a R34 GTT RB25DET Neo, you can pick them up BRAND NEW for around 1k, i priced one up for me with a boost control kit and it was around 1.2k shipped from japan, i know thats a bit over the nistune but i recon they are a better option

The Nistune is the better bet for price and simplicity. Send ECU away to Nistune (or find someone who can desolder/resolder new board). The hidden cost from Nistune comes if you buy the cable and licence to make changes yourself. Are you really going to make changes? Do you have any tuning experience?

The PowerFC would also require sorting out a 3.6-3.7v feed to pin 51 to get around traction control/engine check lights.

I use both and both are good options.

Adaptronic are cheap and finding a few friends these days if you want something with more bells and whistles.

I echo Wolverine's statements

Nistune is great for the price and also stealthy since it's a daughter-board and is installed on the ECU itself and you get to keep all the factory stuff

PowerFC being a complete ECU solution will give you more bells and whistles but personally the hand controller is cop bait...

Nistune will allow you to tune yourself (with the individual licence) but you need to have some tuning knowledge

When you send your Nistune away for them to install it, they will install the stock tune so once you plug it back into your car, your car is driveable straight away (I would find a official nistune dealer who can supply, install & tune for you) - whereabouts do you live 99RS4?

Hey I'm new to replying and posting usually just read, but I'm after a peace of mind.

I have an 99 r34 2door manual awd neo25de... Iv been offed a neo25det awd out of a stagea and was just wondering what I would have to do for a engine swap, is it a pretty straight forward swap? I have a power fc with hand controler in the box waiting to be used for a 34 gt-t.

Engine swap should be straightforward although would be good if you could get the loom with the neo engine. You would want some better brakes and a new radiator and go straight for a FMIC. As the Stagea was probably an auto you need to change the spigot bearing in the crank.

    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
    • When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
    • So I found this: https://www.efihardware.com/temperature-sensor-voltage-calculator I didn't know what the pullup resistor is. So I thought if I used my table of known values I could estimate it by putting a value into the pullup resistor, and this should line up with the voltages I had measured. Eventually I got this table out of it by using 210ohms as the pullup resistor. 180C 0.232V - Predicted 175C 0.254V - Predicted 170C 0.278V - Predicted 165C 0.305V - Predicted 160C 0.336V - Predicted 155C 0.369V - Predicted 150C 0.407V - Predicted 145C 0.448V - Predicted 140C 0.494V - Predicted 135C 0.545V - Predicted 130C 0.603V - Predicted 125C 0.668V - Predicted 120C 0.740V - Predicted 115C 0.817V - Predicted 110C 0.914V - Predicted 105C 1.023V - Predicted 100C 1.15V 90C 1.42V - Predicted 85C 1.59V 80C 1.74V 75C 1.94V 70C 2.10V 65C 2.33V 60C 2.56V 58C 2.68V 57C 2.70V 56C 2.74V 55C 2.78V 54C 2.80V 50C 2.98V 49C 3.06V 47C 3.18V 45C 3.23V 43C 3.36V 40C 3.51V 37C 3.67V 35C 3.75V 30C 4.00V As before, the formula in HPTuners is here: https://www.hptuners.com/documentation/files/VCM-Scanner/Content/vcm_scanner/defining_a_transform.htm?Highlight=defining a transform Specifically: In my case I used 50C and 150C, given the sensor is supposedly for that. Input 1 = 2.98V Output 1 = 50C Input 2 = 0.407V Output 2 = 150C (0.407-2.98) / (150-50) -2.573/100 = -0.02573 2.98/-0.02573 + 47.045 = 50 So the corresponding formula should be: (Input / -0.02573) + 47.045 = Output.   If someone can confirm my math it'd be great. Supposedly you can pick any two pairs of the data to make this formula.
