In 2005 I bought my used 2000 Maxima from a very small used car dealer in Taipei. The owner of that used car dealer gave me some final words when I was leaving...

He told me that "Please remember that this Nissan will last very very long time!!!" (Actually I already knew it)

Similarly, now I also have some words to everyone here...

That is... "If you are a Japanese car enthusiast like me, please do yourself a favor. Do NOT underrate your Japanese cars especially for those premium ones like what many other people did!!!"

Today I cleaned MAF sensor for my GSF...

(The engine room looks a bit dusty as it's already 4.5 year old now. Anyway. It's just cosmetic. So, I don't care...)

I have done this and throttle body clean on my Nissans 2007 G35S, 2010 M35X for every 50K kms. So far so good...

I usually did both at the same time on my Nissans.

However, GSF is a Lexus and also a more complicate performance car. I'm new about Lexus or Toyota. So, I decided to do ONE at a time. In case I mess up something, I still know what the source of the problem is...

I will do the throttle body clean (and idle learning if needed) next week if everything is good...

By the way... Please be noted that MAF sensor is very sensitive. So, do NOT drop it. Be gentle. Otherwise, you may need to buy another one...

In addition, both of my Nissans have TWO intakes, TWO MAF sensors and TWO throttle bodies. So, I have to do them for both sides. One is the left and one is the right!!!

Actually MAF sensors are very critical on how immediate your throttle response is...

MAF sensors will provide the best estimate on how much air goes into your engine. If you floor your car, MAF sensors will immediately notify car computers that there will be a lot of air getting into the engine. So, computers will let fuel injectors to put MORE FUEL into the engine in time...

O2 sensors could also do the similar tasks but if you let O2 sensors to notify computers that change... It would be TOO SLOW!!!

With some small modifications like headers, intakes and exhausts this old ISF is almost as fast as a brand new GT-R or NSX!!! rock

100-200
GT-R/NSX : 7.x

This modified ISF's engine is still NA. So it probably also lasts longer than the turbo engines in GT-R and NSX... 拇指向上

The winter is coming... Today I changed 1 click down on front and rear for my GSF's Ohlins suspension. Now the setting is 9/14...

(Of course, I will also change 1 click up on both when the summer is coming)

In the past I always changed 1 up click when the summer was coming and never changed down. Therefore, the ride became stiffer and stiffer every year... (hoped to keep well-damped with those much stiffer springs)

However, now I think I really don't need to do that. Even with softer settings this suspension still performs much better than OEM suspension. (of course in some ways!!!

)

The OEM suspension is still less bouncy most of time (even compared with my fancy Ohlins suspension).

That's because the natural frequency on my Ohlins suspension gets much higher with those stiffer springs. So we should NOT compare two suspensions with very different natural frequencies. If we keep that in mind, I think we don't really need to go very stiff with Ohlins suspensions!!!

(I always made this mistake in the past)

Like I said about many things... Higher natural frequency suspension has pros and cons...

That's why cheap Hyundai's stiffer (i.e. higher natural frequency) suspension is NOT better than much more expensive M850's softer (i.e. lower natural frequency) suspension. Of course...
