So I have spent some time looking at options. While I see a few options . And have spent some time reading up of them. Most can get confusing at least for me on the best and easiest way to go about tuning the NSX . Any help???
Any advice on tuning the stock ecu?? Ive seen you post in the tuning section but that rabbit hole lost me . ALos how do i raise the RPM. LOL . Looks like i need a billet pump now. Time to search some .Tuning the NA1 NA NSX is difficult and expensive. But it can be done.
Your major limiting factor is the 240cc fuel injector. It maxes out around 290 crank hp. Adding aftermarket headers and exhaust will put you there without any tuning needed. After that, it's $$$.
The hardware formula is well known: camshafts, 36mm intake valves, bigger injectors. Also, if you raise the RPM limit past 8,000, you MUST get a billet oil pump gear. The OEM ECU is tunable with some modification. Honestly, I'd probably just get a Haltech Elite and tune it that way. You can get up to 330-340 crank hp with the stock intake manifold. ITB can get you closer to 360-370 or more depending on cylinder compression and rev limit.
The NSX ECU wasn't ever cracked the same way a lot of others were back in the day. If you follow the ECU tuning threads you'll see that they have really made some progress in the last few years, but it's not as simple as just burning a new ROM to get X tune with a bunch of features.Thanks guys I have headers and few other things. Im asking about actually tuning the ecu. I seen there is a way to do it via oem ECM and of course I know about standalone or even piggy back. I gues im asking about the ecu tuning as i wnt in a rabbit hole trying to understand. I know back in the day we used to burn a rom for the 300zx to make them fast .
Tuning the stock ECU is only possible using a EPROM emulator like the Moates Demon II or a piggyback solution like the HKS Fcon V-Pro. Here is my ECU with the Demon.Any advice on tuning the stock ecu?? Ive seen you post in the tuning section but that rabbit hole lost me . ALos how do i raise the RPM. LOL .

All of the SOS options will be too large for stable idle on the 3.0 NA- they are designed for FI. All of us with modded NA cars use the OEM Acura RDX injector, which is 410cc. If you don't want to drill out your intake manifold, I recommend a set from RC Engineering in the 300-400cc range. Those injectors fit the NSX intake manifold without modification.

Same answerI should have been more specific, the Engine size here is 3.2L NA
Did you mention how you were going to control ANY new injector that isn't stock? Without a way to modify the OEM ECU or without an aftermarket ECU of piggyback you will not be able to use anything outside of stock.Would these ones fit without any physical modification ?

I’ve considered Haltech too (If I ever go ITB’s), Who do you plan to use to tune the Haltech ECU for you?Yeah I plan to go with a standalone ECU (certainly Haltech). Planning to upgrade injectors at the same time. (edit) i'm not going with ITB though, even with Adnan pushing me to do it. My car is too noisy as it is and finding a race track that wont eject me outright is difficult with my current setup...
That's the big $$ question. I have yet to find someone confident enough to tune my car, and also plug the Haltech ECU in my OBD1.5 unicorn NA2 (I'll certainly need a custom harness and/or spark plug coil adapters). I'll probably concede defeat and go to the Netherlands to have Adnan do it all but that's a huge distance... when I talked to Yamamoto-san (at NSXCE) he told me he could fly in from Japan and tune the car here but I suppose I'd need to find a local roller dyno in addition to his plane ticket and fees, another expensive proposition...I’ve considered Haltech too (If I ever go ITB’s), Who do you plan to use to tune the Haltech ECU for you?
Honestly I thought about Motec too as there are racing shops in France where they use that. But the price hurts.FWIW if I was to do this over again i'd also go Haltech or LinkECU for a budget solution. It really depends what you're trying to accomplish and how many features you need. Sometimes simple is best. If money was no object Motec for me.
What about Christian at ATR? He has a really good tuner.That's the big $$ question.

And goal is to get a NA tune to start with, and make it simple and clean, and keep the cruise control which is absolutely essential for me to keep my driving licence (as some NSXCE members can attest, I seldom look at the speedometer) - which rules out the AEM.
That's maybe an option too if he can tune Haltech but also a very long (and expensive) drive. That's why I was looking in my area (around Geneva / Lyon maybe) but if there's really no one, we'll see... NA tuning doesnt give huge results on the NSX so adding the travel expenses (and maybe transporting the car) on top of the price of the ECU and tuning, the hp/$$ ratio is falling fast !What about Christian at ATR?
