Nissan Qashqai 2014

No harm trying lar. This is what I observed. It also make makes the car more responsive n able to move from red light with ease.

i was initially skeptical that turning e temp down wld make e car more responsive but tried it nonetheless cos i hate e random periodic sluggishness e car experiences.. surprisingly e car really felt smoother n e lag was significantly shorter at 22 deg, eco n start/stop off.. i thought it was juz my mind wanting to believe that it works so i repeatedly switched between 22 n 24 deg to test n it really felt better at 22 deg.. still dont get how it works though n TC shld really check n verify this to solve all of our problems.

Wow! When did u guys meet? Where?

I drove once with aircon at 18degc (accidentally set) and throughout the journey wonder why start/stop didn't activate at junctions stops. When I realise and set the temp back to 24, start/stop activates immediately at my next stop.

Maybe when aircon is set lower, the load or power demand is higher and therefore start/stop will not cut in. My guessing only.

Yes TC should rectify this issue. I am eagerly awaiting the new SW update release in Feb..

What temp do you normally in? 24? No lag no loss of power? Hmmmm.... thus random cars?

Hi, would just like to check with the bros here. Anyone one of you have tried RS Chip (http://www.rschip.com/benefits/) on your QQ? any feedback?

My QQ is coming next week. Hope everything soon soon...

Lucky to have won $1000 Shell & $50 SPC petrol vouchers during Nissan Motorshow draw. :)

My reading of your description as follows :

When start stop is invoked, battery alone is supplying power to air con. At 24 deg C setting, the battery is doing without the car alternator (which is off since car is not running) but is being depleted in the process. At 18 deg C , the demand of the air con condenser is much higher preventing the car from performing start stop operation but since the engine is running there is the alternator supplying the power to the air con and therefore the battery is not burdened with keeping the juice flowing to the air con. So under this lower air con temp setting , the battery is that much more dedicated to servicing the engine spark plugs etc rather than in the 24 deg case where it is starting from a more depleted weakened state (from the engine restarting action itself which draws power) , needing to charge more to the spark plugs due to increasing rpm as well as simultaneously powering other parts (eg the cvt) plus others ( including radio, camera, gps, DRL, etc.

So the observation about the air con temp setting having a link (and a basis for solution) to this is possibly a valid one. Which could explain why it appears to be selectively fugitive and to affect some and not all.

Congrats . Wah 2 ANG POWs :

1. You get a new car for the new year.

2. $1050 vouchers

And from what is reported you will get the software fix for 1.2 T (this is your model right) in feb too

My start/stop is on but not activated when the power loss happened. After sending in for tuning by TC it didn't happen again but my brakes issue still happens intermittently.

But if I don't release parking brake and just step on accelerator, letting the parking brakes auto release will not jam my front brakes. Sounds funny but TC said once I step on acc, the engine/ecu sense the signal and will not lock my front brakes.

Now TC is also waiting for new software in Feb and all affected owners will be notified once it is available. The new software should rectify both power loss and front brakes issues so any owner experiencing either problem should report to TC so that your details are locked into their system.

And yours look like brake related. So it is more than a one dimensional effect Edited January 24, 2016 by EricChan

Yes mostly between 23~24deg, and already experience power lost twice in first 2 weeks of getting car. Want to highlight again the power loss is when moving off, stepping on acc but no response in vehicle movement, car just crawls...it is different from cvt lag or turbo lag. However after TC did some tuning I don't encounter it anymore.

As some bros here mention the power loss won't happen if start/stop is turn off, then only way I could link to the colder settings of aircon is the higher load demand where start/stop will not activate.

Thanks Eric! Yes hoped to have a good year ahead!:)

I think I'm the first few to try out the 2nd gen RS chip OBD direct in my QQ. Before using RS chip, I tried the ProRacing OBD tuning chip without setting and it was pretty responsive with reduced lag. With RS chip, there are 4 settings via Bluetooth on your smartphone - Sport+/Sport/Stock/Eco modes. The Sport+ mode is extremely responsive with very minimum lag/retard and turbo kicks in with a bang with RPM shoot up high and fast. According to the dyno test done and shown in RS website, the improvement in peak/max torque is almost as high as Qashqai 2.0 but with peak torque at less than 2000 RPM. As for horsepower with RS chip, it is over 10% increase shown in the website. Anyway, with my already installed ignition grounding and power chargers mods in my QQ 1.2, I can still feel further improvement on response, pickup and acceleration with RS chip. It is a good buy imho and anyway, I got a good deal for RS chip from the grounding/power charger dealer.

Had spoken to the service mgr, apparantly there are quite a nos of complain on the front brakes locking issues and is also link to a bug in start/stop software. He mentioned many others had off the start/stop and did not encounter the brakes lock again.

But I do find out that my brakes issue did not appear again if i use the method of auto releasing of electronic handbrake by tapping on the accelerator, even with start/stop on. At least till now.

Standard 2.0 rims wont not fit anything above 225/45/19 as it is 7J

U need 8J to clear 245/xx/19.

Widest u can fit is 235 45 19.... In fact the ride will be more comfortable and the tire will protect the rims. The problem is limited selection on this size.

Thanks for the reply bro, with all those changes does it affect your warranty with TC?

Not sure about u guys, I drive with auto release everytime and with stop stop. No issue at all. Acceleration also no problem.... Now my car very quiet except Kenna bump then got rattle in the front console.

Anyone knows where is our mini turbo located? Possible to upgrade to larger turbo?
