Thanks for the post Dave! Very informative. I'm actually going to take my car to dyno this Sunday and very much needed this info! Looks like I'll be trying VSC&TRAC off, ECT-Snow, and putting it into manual mode with 4 as the highest gear..? I got the F-Sport intake, Invidia midpipe, and Tanabe Medalion exhaust if anyone is wondering. Hopefully it works, we'll see!

 

^ looking forward to seeing your results (OP's too). the above mentioned method is much preferable to the pedal dance method (which i could not replicate in my GS for whatever reason).

 

With my GS460, i just press the traction control button for 3 seconds and it's all off! No questions asked. My buddy's GS430 doesnt have that.

 

I predict 260whp! IT would be instersting if an american 460 dynos as well!!

 

make it happen...you can see the link Dave showed from my car. I'm telling you we tried everything possible. Only thing that was shared to me from member Mr Johson was SRT had to cut some wire on his 2gen GS to dyno/tune the car since it wouldn't hold gear.

I used the methods they did with the 2gen ISx50 as I had one prior to the GS. Snow mode worked better but it wasn't accurate. If I recall it showed ~150 hp for my car? They did extra pulls for me in an attempt to get it to work. I may have the info saved on my PC since the emailed it to me.

The tech's I asked at the dealer said they thought the hold up was our electronic brake system. Its too smart to see the front wheels were not moving so it was throwing the car off?

 

I don't have snow mode. It says "Normal" or "Sport"

 

the swithc next to it that says "PWR" should say "SNOW" also

 

yeah, designo, the button you looking at is the avs button. you need to look at the pwr button

 

with the TCS as sensitive as can be the car may be a pain to dyno

 

We do not have snow mode on our GCC spec cars.

 

interesting (but makes sense), learn something new every day!

 

maybe they wont have the issues I had when trying to dyno my car? I wish it was the same so we can see what the hold up was and if there is a way around it with out modifying anything.

 

I will video the dyno runs from inside the car. Stay tuned boys

 

Can an AWD be dyno'ed?

 

^ Yes, if the right facilities are present. There is a specific dyno for AWD cars.
