Protegimus,

two things.

1. making something that sounds crap louder doesn't equate to making it sound good. I believe you can't polish a turd is applicable here.

2. the lexus LFA is one of the greatest sounding cars of all time and is Japanese.

Actually, I've already cited the Lexus as an example of what can be achieved and suggested Nissan (nismo) speak to Yamaha rather than produce another aural disappointment. However great an example, you have to admit it's not exactly representative though.

Sure, it's not going to sound like it came out of Sant***8217;Agata Bolognese or Maranello, but it can be seriously improved, Russ Fellows, MeisterR, Akrapovic with a gentle rev...
Anyway, let those that like a bit of raunch/character even when not doing warp speeds get on with it and may those that prefer quiet be reverent.

Back on topic, logged downhill acceleration runs and submitted to Iain - hopefully he'll be able to work something in for those particular circumstances. LTC still effects and is a lot less abrupt than factory, but would be ideal if it could be further refined.

Callum, Our Traction Control setup is designed sit as an extra layer above the original systems. It starts working gently before the Normal Nissan VDC setup has reacted. We don’t close the throttle (like the Nissan system) so it’s a smooth reduction of power, varies with speed and the amount of wheel spin detected. Our traction control intervention kicks in more aggressively as needed and you can still trigger Nissan’s VDC safety net in R mode. However now it’s not as harsh if it does intervene. It also means you can keep Nissan’s stability control which brakes individual wheels to balance the car in Normal and R mode.
You can run the LTC on its own with all of Nissan VDC systems off and you can turn it off as well
Sounds interesting - thanks for the reply Iain. :thumbsup:

When I asked a GTR tuner why the current crop of GTRs and Evos sound like hoovers I was told that mass manufacturers have to follow strict noise limits on their cars. Specialist firms like Ferrari and lambo etc have a dispensation from these limits, so it may be legislation. I don't know how much truth there is in this but it sounds logical

Dylan how are the new v4 features with your stage 5? Have you had your maps fine tuned and done some driving to evaluate the improvements against phase 3?
Feedback from others? I'm interested to compare experience.

Had a drive earlier this evening, some logging as mentioned and in the cool (5c) moist conditions the car is rapid, "it seems to be performing well" Mr. Litchfield commented!
LTC definitely doing its stuff as chucked it in Map 4 to feel the old Nissan TC and it's a big step forward in my mind.
Many will be pleased to know that you can still drift it (well, mini drifts for me) with LTC in the mix!

Noise. Volume and character are not the same thing.
Mass manufacturers, Merc, Audi, Porsche, Jaguar ...Lexus?
Or is it rather that they have to conform to strict Japanese regulations and simply don't bother to engineer for other markets?

Totally agree with noise and character. iF it had more character, I'd be ok with more volume, but it is noise, not sound, so why turn it up.

Re phase 4, I have to say that the LTC is such an advance that I've not given much thought to the other new features.

I've not even switched it into manual, never mind R mode.

New power and delivery is such an assault on the senses, that I'm not sure my brain has the bandwidth yet to cope with all the toys.ant stress enough how much value the LTC has added.

I would have gone down this power road anyway, but it would have been a mistake without syvecs traction control.

Thankfully LTC allows it to remain drivable until the change to syvecs when I'm ready to make the leap.

Adam, As you wanted your GTR VERY quiet we’ll use you as the worst case/judge of noise ;) I’m pretty certain that if we enable pops and bangs on your car that you’ll want to keep it. They are not particularly load in this current setup and add a bit of character to the overrun :)

Satan & Ian, we have a slope near us which would always trigger the traction control if you go on the power to early in Normal or Race mode but it would be fine with the traction turned off. Our Traction Control won’t effect this but it does mean you can have a bit of help even with the Nissan’s systems switched off. If however the Nissan traction control is kicking in for some reason on your cars when you go downhill (even with everything off) then our system won’t change this.

LTC is always updating so we welcome all the feedback. We hope to go back to the Airfield next week to see if some of the new inputs make a worthwhile addition :)

We’re testing 5 different intercoolers at SRR today so in between the intercooler changes we’ll be updating maps (assuming Charlie’s WiFi is working).

Morning Iain did the cable go out and can you include the pop and bang in the file you're sending me please

We have just finished a V4 motorsport map from Litchfields for a customer and have to say am impressed ;-), you can now fully plant your foot down and not have the horrible trac cut out spoiling it..

(Last few days in Newcastle have been cold and damp aswell)..

The car just goes like a snake fighting to keep it straight (but it now goes as opposed to ecu cutting it out)..

It certainly a good upgrade to have ;-)..

Reminds me of the JUN R1 fighting the tarmac now to keep grip and stay in straight line.

(I can see peoples times improving all round)..

Adam, depends on your personal definition of character and noise, it will be subjective so I guess we'll have to agree to disagree.

Protegimus,

Ian has been busy fine tuning my V4 Stage 5 map over the last few days (many thanks IL) and my initial impression is that the car doesn't feel any smoother as such I think the big leap there was done in V3. What is noticeable is the grip on hard acceleration and around corners, I've driven the car now in scenarios of past which would have had the traction control light flashing like mad (in stage 4+5 guise) and the corresponding loss of power. Now the car just pulls hard in all gears without loosing grip (and hence no power cuts), the car just goes and goes.....

I'm not sure how much better it would be with Syvecs but for those who don't want to or cannot afford to go down that road I think this is a massive improvement from the Nissan TC particularly if you car is tuned. Well done Litchfield :bowdown1:

I haven't tried the rolling launch yet but I'm looking forward to trying it soon. I'm also looking to do some comparable 0-60 and 0-100 pulls on the Racelogic box and some 30-130 pulls using the Rolling launch and not using it...

Loaded up my first Iain tweeked rom yesterday. Awesome, I need to ask him a couple of questions but the car feels another a big step up.

The V4 rom was great, and I sent Iain the log for it but as if he 's now made it an animal.

Need the check with him if some of the readings are right

Haha, not yet. Iain want another couple of logs before that. There was a wee boost spike on the first log which he wants to dial out before the pops and bangs

Yea, I need to do another logging session, just getting the time! I so want the pops and bangs, but I don't have the time to log at the moment :(
