Just wondering what is the cheapest way to "get inside" the management system of an R32?

I just want to change the fuel and ignition maps a little to get it runnign sweeter. Mine is over fueling a bit even tho my Oxy sensor is new, and I think the igntion timing could be better.

Apexi fc? or something else??

has anyone tried one of those kits from jaycar that are meant to adjust the ecu's closed loop mixtures?

+1 for nistune. will get you there for about half the cost of a pfc. should be under $1000 installed and tuned.

also the oxygen sensor won't solve any over fueling issues you are having when you floor it. they are only designed to help with fuel economy at light throttle applications. once you floor it the ecu ignores it.

if you don't know what you are doing i strongly advise to not try to tune an ecu by yourself as you can have some pretty serious effect on the car and not only end up with less power but also possibly end up damaging the engine.

+1 for second hand PFC, mine should be coming up shortly for sale.

Id be very interested in that! Let me know:)

How do they reprogramme the standard ECU? Do they take out a eprom and put it in a eprom reprogrammer? or do they have a way of connecting a laptop up to the standard ecu and changing the values on the fly?

www.nistune.com

Yeah i was looking at that a while ago, and read the whole website this morning. Think ill order one, as I dont think ill be able to refrain from biulding up the engine in this car in the future anyway haha

Do i have to buy a consult cable?

Nistune will definitely be the cheapest option and probably the best for what you need. If you are thinking about modding your car later on down the track than maybe go for a second hand Power FC unit but it will be would be more expensive.

The jaycar kits are decent - we have used them on cheap old cars to good effect and because they are pretty cheap you might want to try it out and see if you get the results you are looking for from it. But I would probably stick with the nistune for the safer alternative.

can you tell me a little more about the jaycar one? does it actually take over control of the injectors? or modify the incoming signals? how is it programmed? can mixtures be changed while your driving? or is it simply a program and go arrangement?

i think the jaycar systems are just a signal bender. they alter the signal coming in from the AFM to trick the ecu into thinking that less air is entering the engine so it puts in less fuel. the downside is that you can't independantly alter the timing or the fuel at different revs or throttle loads. they are ok as a cheap basic alternative, but won't give you the gains of a fully programable ecu

+1 for NIStune. Do it! Best money you'll spend on your 32. Consult cable is good if you get the software as you can log and bring up digital dashboard with just about every gauge you can think of, even injector duty cycle. Plus you can then run it like a diag PC and knock out cylinders for testing and get ECU error codes etc.

Technical parameters: - Axle: front. - Disc type: ventilated. - Number of holes: 5. - Disc diameter: 310mm. - Total height with center: 54mm. - Thickness (new/min.): 30/28mm. - Designed for brake calipers manufacturer: Sumitomo.
    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
