Just wondering,

When a tuner is tuning your car. They are doing it for the particular atmospheric conditions at that time.

After reading a few of the recent posts. They have said that in cold weather your car is more prone to “ping” due to the denser air. But this is also true in hot weather.

If this is the case. When is the best time to have a car tuned? What can be/is done to overcome this?

I always thought the colder the air the better.

On a cold night should a person run Less boost than on a normal day.

Thanks guys

Got agree here, colder air is much better and prevents pinging.

Hotter air is less dense....ie

..anyway, regardless of the density, i think it's the higer temps that cause the pinging.

...but back to the dyno subject....i had mine done ages ago just for fuel/air ratios and they were spraying water onto my standard intercooler....later i though that was a bit stupid cause i don't have a spraw when on the road...sometimes i think they just wanna improve their rwkw reading to make you think they've done a good job (not all of course)

yea i would be interested to also note what people think about tuning in regards to a SAFC. Obviously you want to get the most power out of the car by leaning the mixture out but at the same time especially in canberra our temps change dramaticly. eg summer up to 38 + days winter nights that are anywhere from -6 or so. Would you generally want to get it tuned up once every 6 months say to get the mixtures right or do you generally just leave it a little rich to be on the safe side ???

    • There are several aftermarket options available, from not-too-painful moneyhttps://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35 and  https://justjap.com/products/crank-motorsport-billet-rear-axles-fits-nissan-skyline-r33-gts-t-r34-gt-t?srsltid=AfmBOorQk4xkGUa98kO7v2ePLUiNt-HRrM2AwWNw9mbSIVE1ujBVwY__, all the way up to The Driveshaft Shop https://driveshaftshop.com/skyline-cv-axles/
    • Yeah based on old XRC5964S specs, it looks to be roughly GTX3576R sized? But this 5964S compressor will flow 90lb airflow somewhat similar to the compressors in both the GTX3584RS or G35-1050.. I fully expected the 0.64 rear A/R to choke up top - seems way too small from typical convention - but these are seemingly beneficial over the prior 0.82 results.. Be interesting to see if he comments on the EFR question in that thread - he mentioned in a prior video that BW EFR's were the "cats pajamas 10 years ago", but by the sounds of things all his kits have been using Xona for quite a while now.
    • Yeah it’s still got the oem manual gearbox and clutch, only kinda mods are a blow off valve, coil overs, and a aftermarket intercooler. Also had it for about 2 months now with a lovely midnight purple paint on it.
    • Yeeeppp, been following a lot of the testing on the latest Xona stuff and there are some mental results.  He also went over 1000hp @ 4 hubs on his Mainline with a XRE6364S (63mm) which was also well into the 20psi range before 4000rpm on a 2.5. Crazy stuff. Fwiw the XRE5964S is basically the modern equivalent of their old HTA3582 - would drive nicely enough on an RB25 or 26, but proven capable of a huge amount of power if you want to spicy with rpm tho even at sane boost levels will make stout numbers 
    • The axels in my R33 seem tired, and have a bit of play in them. I cannot find any new of course, not interested in buying used, but I am looking to see if anyone can identify some cross compatible axles. In the states I have seen suggested for S chassis the J30 axles, however for the skyline (as best I can tell) the lengths are about an inch off (2.5cm) on both sides. R33 my measure L 22" R 24.5" GPT L 22.5" 24.25" J30 L 23.5" 25.5"  so shaft length is probably an inch wider. Not sure if someone has another still remanufactured option besides the J30. I figured worst case I can buy a pair tear them down and swap the center shaft. My other option was reaching out to GSP to see if they cannot piece together a set, since the axle stubs are still manufactured, I wouldn't think it be that hard to find a shaft or make a shaft work.
