GT-R Dyno Sheets

Simple. Replace ECU with seperate unit. You don’t think the tuning companies are going to give up just becuase the ECU is hackproof, do you?

:+1 Where there is a will, there is a way.

yeah exactly. stand alone engine management is obviously more work to integrate, but its going to give you the best tuneability.

Replace the ECU and then pack your bags to move out of NY.

Do you have any idea what would have to go into using a stand-alone system in place of the stock ECU? Were not just talking about engine tweaking, you would have to set up Air Bags, Turn Signals, Headlights, ABS, etc, etc…it is a stupid pointless idea

Two words: Hydra Nemesis.

And that’s just one standalone. AEM EMS also does the same thing - and look at its application list. Runs A/C, Power steering, manages ABS, etc. Airbags and SRS devices are no worry, because they’re built as a seperate system, controlled by their own modules.
It’s not too difficult to hack into stock systems and find a way around things these days as long as you have the time to put into the development.
Piggyback units? New 08 WRX has an antitheft feature built into the ECU. Can’t remove it, so run a bypass cable and loop a standalone so it provides the features needed, but allows the stock ECU to cover the things it can’t do.

It’s just tinkering. That includes OBDII. It’s not an incredibly complex system - the main issue is to prevent a check engine light from popping on, which involves ensuring the stock computer sees no system diagnostic faults and that all sensors operate in their correct ranges. TurboXS UTEC did that years ago, along with the ability to suppress CEL’s.

Ain’t nobody packing their bags. We’re just going to become software engineers and scientists more than the wrench-turning gearheads we used to be.

Well then, I guess you learn something every day right?

OBDII + Standalone + NY = Bad idea.

Shawn you have to remember, most of the people who will buy that car, will be indeed car people. And all car people know somebody that knows somebody that knows somebody to pass a car on inspection.

Plus I’m sure there will be a lot of people willing to pass that car, just in exchange for a ride, 475whp remember :wow

It’s not easy. Trust me on that. You need two cars: your car and another car so you can plug the other car in that you know will pass and slap the sticker on your car. Not many people are willing to do that.

Just an opinion, but I think most people who could afford the new GT-R would already have a second or even third car to use for such a trick. The ones modding it to that extent would likely have one shop doing everything for them, probably including making sure it passes inspection.

Sure it’s possible. I have 2 daily drivers and enough money to afford that car and I went through HELL getting my car to pass. Not stating it’s impossible but a pain in the balls.

Your car doesn’t have the kind of aftermarket support that other vehicles enjoy though. The main issue with a standalone is the OBDII system. Standalones don’t emulate it [yet]. If you could keep your stock ECU onboard and wire it to maintain functions appropriate to the CEL, and even better, have it pass through the EMS as a filter to suppress whatever CEL’s would be on their way to the OBDII scanner, that would rock. If you can’t hack the stock ECU, nobody said you still can’t move it to the back of the line as far as new york state is concerned :wink: All the scanner has to see is a system with no active check engine codes. If an EMS could be programmed with the ability to suppress active codes and convert them to “history” codes before they get to the scanner, then as far as NYS is concerned, the car had codes in the past, but nothing currently active. Pass. :slight_smile:

What are we missing for aftermarket? Things are a bit different now. Just expensive still.

Yea, you could do all that but it’s not easy. I didn’t say impossible. :slight_smile:

We’re missing the plentiful parts and shitloads of R&D that goes into vehicles like the EVO, the STi, etc.

:frowning: god it sucks having an older car sometimes.

Older cars rock, everythings been done before so we dont have to spend big money on trial and error. Common cars like the Evo and STi are in the same boat.

Yeah well, older cars lacked body rigidity from the factory, and the age dosn’t make it any better.

You need a full roll cage in older cars now to have any solidity in the body unfortunately, sometimes newer is better.

Plus warranty FTW!

Working on this part.

New cars suck. Depreciation is a bitch. This is why I buy old cars outright w/ cash. Drive them for 3 years, lose maybe $1000-2000 on depreciation while adding 70k+ miles to them.

Warranty schmarranty. I enjoy fixing my hoopties. Except when it’s this cold out.

Warranty? Mawybe if you just do an intake.
