Are any companies working on more power upgrades? Car is 5 years old and still just basic power adders. I would think by now there would be way more upgrades than just cats, exhaust and tune.
Honda has always been a challenge. If I recall correctly even the first generation has not been cracked (91-2005 NSX). AME had units that would piggy back on the Honda ECU. The problem as I recall was that the the ECU would start trying to fix the system and relearn how to run. I don’t believe they ever fixed that. You can run with a non Honda ECU, but there are some issues.
Just curious why 95-05 ECU’s are impossible to modify? I find it surprising that technology that is about 20 years old is still hard to solve (despite the so many advances in tech and tools)
I disagree with that. I had a 92 single turbo nsx fully built engine and it was way more fun than stock. I also own an audi R8 with a TT kit on it, those cars have tons of upgrade options available. And yes, I know tons of people with supercars who would spend money to upgrade. Underground racing and sheepy racing provide kits for R8s, lambos, mclarens, and other exotics. Its clear the nc1 has potential to upgrade, acura did it themselves with the type S. I'm saying, it would be worth it for a company to have a kit that upgrades the turbos, electric motors, etc... Upgrading isn't for everyone, but should at least be an option for buyers who want to spend money
it's really commendable and impressive (these guys have balls) considering the EPA is cracking down hard on these guys like COBB. Go KTuner!
Syvecs mentioned that the Porsche was so quick to crack because it was effectively the same as another platform they've already done. So there was virtually no work to be done. This would be awesome if this was the case with the NC1. It would be like a cheat code.I've talked to some other guys who were working on reverse engineering the NC1 ECUs. The architecture is extremely similar to the 4 cylinder engines so from what I can tell its been pretty quick work compared to starting from scratch.
Currently working with KTuner on this. Just sent some datalogs over the weekend for environmental calibration. I will update with more info shortly.SOS UPGRADES
From what I know the JB4 along with Down pipes and 93 map can net 100hp+ increase overstock.
K TUNER UPGRADES
K tuner is almost done with their ECU tune (anticipate it being released Q3 2023) which allows the NC1 to run a mid 10.5 run, bone stock.
The problem is that extracting more than 700hp (crank) begins to push the limits for the NSX (per ACURA engineers at PMC) as you will run into issues with the transmission, as it will require upgrades to handle more power. That is your bottleneck. I doubt 'ANYONE' will invest the money to offer an upgraded transmission that can handle more power.
I believe they are trying to gather data from multiple vehicles to fine tune the stage 1 before release.I thought K Tuner were finished with the 17-21 Testing (only hiccup is the Type S EPA settings in 1st gear) ?
The source for that info was from the Engineers at PMC. At the moment no one has been able to extract more than 700hp (crank) from the NSX. SOS have a JB4 tune but it tops out at 700 crank and I dont think they want to push it any further.
The good thing is that K tuner will allow more parameters and support (e.g installing bigger Turbos, increasing boost and possibly higher RPM launch), but the Transmission will become a bottleneck (to what point, no one really knows).
Perhaps SHEP could possible offer a Transmission solution if there was enough interest?
I am still running the stage 1 tune but have not submitted any new data logs for a while. Everything is running as expected and the car feels great. No updates on full release as of yet on this end.Any updates? I still don't see anything on their website regarding the NSX.
Can you elaborate what you mean by "feels great" i.e. faster, smoother, 60-130, 0-60, etc.?I am still running the stage 1 tune but have not submitted any new data logs for a while. Everything is running as expected and the car feels great. No updates on full release as of yet on this end.
Meaning the overall feel of the car was improved after the flash.Can you elaborate what you mean by "feels great" i.e. faster, smoother, 60-130, 0-60, etc.?
Thank you for the detailed reply. I'm and probably the rest of the NSX owners are eagerly waiting for the release...Meaning the overall feel of the car was improved after the flash.
The throttle response has improved over stock, so much so that on a very bumpy road it is actually a little sensitive.
The power through the entire RPM range feels greater and more linear. It pulls significantly harder to redline.
Traction is going to be an issue with the extra power. The tires (fairly new Continentals) loose grip more readily and leave you compensating more than normal. The rear end will step out more noticeably, so be prepared.
The normal daily drivability is the same, but as soon as you smash the pedal it feels like a totally different car. I am hoping we can extend this to the steering at some point to mach the feeling.
At the moment I don't have a way to verify 60-130 or 0-60. I am however confident in saying, it will be a major improvement on both accounts.
For me there are no drawbacks. I think this will be the best "bang for the buck" mod you can do to this car.
Yes, you also have the option to connect via Bluetooth if you wanted to use a different application to view the parameters.When it comes to the implementation technique, how does K Tuner's solution compare to SOS JB4? Is it more like a true flash where the parameters are updated and there's no need to keep a device installed in the car?
