2018 Z's Concept of acceleration??
 

There isn't a lot of information on google for this change but its mentioned here...

2018 Nissan 370Z Coupe Press Kit - Nissan Online Newsroom

.."Without changing the engine's internal structure or components, engine performance is improved through careful refinement of Accelerator Pedal Opening (APO) and Throttle Valve Opening (TVO) angles"

Does anyone know if this feature can be ecu flash into older Zs?

2018 Z's Concept of acceleration??
 

Hmmm interesting! That’s news to me. I wonder if they just retuned the throttle response to get rid of the dead zone at the beginning of throttle travel? It seems to apply only to A7 cars. Hopefully someone will chime in with more info.

Does this mean something will happen when you push the gas now?

That dead zone is awful, even with a manual.

I have a 2018 Sport Tech manual. Throttle is crisp. No dead spots.

Plot Twist: They added Sprint Booster. :rofl2:

Kidding aside... wish they figured that out so many years ago. It's difficult to blip the throttle on downshifts compared to the 350Z, and it lacked the neck snapping response as well. I can only wonder what it would be like boosted.

Weird thing is it wasn't really something to "figure out". I'm pretty sure it's a straightforward parameter to adjust.

I think even EcuTek Connect BT can let a user do it on the fly if the tuner unlocks the setting.

Sounds like they've just adjusted the same parameter that is done with ecutek to eliminate the dip in the throttle curve, probably still not truly linear as the tuners set it because that would probably be too touchy for a majority of drivers.

I agree
Ecutek tune to very light pedal.I know everyone makes fun of Sprint booster(just opens throttle more with less pedal travel to start; the end result is the same.Yes you could just mash pedal harder to get same result.).I put mine on after Ecuteck tune.I have no lag.Before tune and Sprint booster the lag was very noticeable.The way I have set would be too touchy for a lot of people.I do not think Nissan is not doing much more than this.

Thanks everyone for the input! I'm still under warranty so a factory tune to fix the throttle sounds great. I'm still not clear if a dealer can simple reflash to a 2018 map or for that matter would they even agree to it

I would be willing to bet money that a Seb-tuned Z on Ecutek is still better than any tune Nissan has put on any stock 370Z.

Way to go Nissan. It only took 10 model years :rolleyes:

Also very interested in the dealership ability to flash a Nissan approved update into my 2014.

MOAR INFOS PLEAZ!!!

Well they aren’t working exactly the same. With drive by wire it isn’t uncommon for the manufacturer to not have a linear curve but the two extremes are still accurate (0 app=0 tps and 100 app=100tps) its the middle areas that aren’t = to each other. The sprint boost fixes this I believe by boosting the app signal but this comes at the cost of the throttle going to 100% before the pedal is actually at max. With ecutek the tuner can do the same thing if you request but I believe it’s more common to make the throttle truly linear and just fix the middle zone. You can read about it in the ecutek tuning guide if your more interested.

Worked on this quite a bit on tune.Pedal as set by tune is close to linear.Tried a few different ways.Bounced back and forth on this.Still had slight hesitation.(dead spot).Vastly improved over factory.Drove like this for awhile.Put the Sprint Booster back on.No dead spot.Yes the boosted signal opens throttle to 100% before pedal is all the way down.Not sure of your point here.

Is this going to be a Sprint Booster debate.

On impulse I called a local dealership yesterday, to late to speak to a service mgr but Im on callback. I'll try three locals for different opinions. Can't say Im optimistic but we'll see...

10 years, no power increase and frustratingly, no serious interior updating. :koolaidwall:

lol so asking a local service dept if my ecu could be updated was painful. Knew I was in trouble when they asked for the vin. After a brief hold the tech states "there no tsb for your model"; sighs. I attempted to explain this isn't a tsb or "fix" but rather a performance improvement, like getting an android update hehe. I heard crickets and a final bring the car by we'll take a look. I'll pass lol, moving on to next shop. More later...

I have the same and agree

Would like to hear from someone who's driven both the 2018 and earlier versions(s) as to whether throttle response has actually improved perceptibly. If Nissan's tinkering hasn't really changed the driving experience, this is all a moot point.

I've heard it time and time again... mashing the throttle does NOT help. I can floor it and there's a delay or slow ramping in acceleration as if I'm starting off in 2nd gear. In fact, the turbos had trouble spooling up until it hit 4k RPM. What seems to work is slightly blipping the throttle before engaging 1st. I once had the brake pedal switch replaced, which brought back the response and screaming engine briefly. Before I sold the car I seem to have resolved the power degradation issue by replacing the MAP sensor. New owner seems to have enjoyed the car since then with no complaints.

Compared to the 350Z, I think the 370Z's throttle response was atrocious.

There's no point in getting a half *** factory tune and hack sprint booster when Ecutek fixes this and gives the tuner more granular control. You also get the benefit of a tune, better traction control management, launch mode features, antilag, and map tuning. The only nice update is the S007's and that passion red color. I'm still partial to Magma Red though.

Is yours a manual or auto?

Ive mentioned that Im under factory warranty so no surprise I'm also stock. Even with no warranty I no interest in tuning a stock ride

Perhaps you could swap in a 2018 ECU? Just throwing an idea out there.

Can confirm.

Drove a 17 then bought a 18 ( both 6MT base ). Clutch and throttle feels sharper.

How’s the inventory of Z’s up in QC ‘fungole’? Curious. Manual Sport Techs are scarce in US. Dealers seems to carry only base and touring in automatic.

For anyone interested. I checked with several dealerships about flashing my 2015 model ecu to the 2018 software. Dealerships are only authorized to update ecu software based on the vin, none were willing to take the risk of anything happening with an unauthorized flash. Nissan would have to officially release the 2018 enhancements as a software update to older models. Moving on

Just got rid of my 16’ and getting my 19’ next week. I can update as well once I drive it bit as you heard, looks like they improved throttle response.

Thanks for updating this issue for everyone!

I own a 17 and have driven an 18 (both 6MT Touring). Clutch feels smoother but throttle feels the same (no dead spot). :icon14::rofl2:
