The HDSS should hold fine, unless you're driving abusively!

@CSG_Mike How is the pedal feel with the OS Giken vs the ACT? Stiffer, lighter or about the same?

ACT is heavier at the hump, and lightens at the bottom, like OEM.

The CSG OS Giken single is lighter at the hump, but (almost) linearly increases in weight as you go down.

You guys' impressions are super useful. Thank you so much! I know a stiffass clutch will hold, but it takes a lot of practice to launch without shuddering. I'd love to avoid that in this car!

Both suggestions I made are 100% streetable with a minimal learning curve. If you're getting shuddering, you need to give it slightly more rpm.

After 14 years on my stage 4, 6 puck CC on the Acura, I’m good at it lol. Just not really wanting to roll that way with this car. Thanks again for these options.

Finally did my 3.7 final drive gear over the weekend and I love it. If you're on the fence just go for it. I'm measuring roughly 6 mpg higher average on the interstate and it's much quieter at the lower rpm. You'll basically lose 6th gear for anything other than interstate driving however. It still pulls great through 3rd, which now gets me over 100 mph.

Did you do this mainly for the MPG and noise or so that you can stay in 3rd for a specific speed range? do you not feel it struggle more taking off at lights or do not car?

B T · 12-30-2022, 09:38 AM

I wanted a little better traction in 1st and 2nd on ethanol, less noise and more mpg so it was just all around a good idea since I daily drive my car. It won't be as fast out of corners at the track anymore but I'll still have fun. It does struggle a little at the lights, but it was already struggling with all the parasitic loss. Overall driving is much more relaxed. I wonder if the 3.9 may have been a better option but not going to change it again. NOLA usually gets me up to about 120 on the straight, most other places in the south east is 110, so the gearing fits pretty nicely.

I have a 2015 FRS with an Edelbrock kit, bigger fuel pump, 700cc injectors, catless header with TRD exhaust, and the Delicous flex fuel sensor and tune. I am now on my second tune revision and still having idle issues.
Car has about 94K and before the swap ran fine with no idle issues.

The car will cold and hot start fine and seems to run fine everywhere except at idle. At almost every stop it will either idle around 1900-2000 or bounce from 500 to 1300ish over and over. It has also died several times in traffic.

So far I've pulled the battery and done the complete idle re-learn procedure several times. Cleaned the battery terminals and alternator connection. Cleaned the MAF and TMAP sensors along with the throttle body. Iv'e also checked for vacuum leaks with no luck.

What do I try next?

dpfarr · 01-07-2023, 01:17 AM

No codes?

Is your tuner unable to give you any direction on possible causes?

probably tune related , as for example a bad maf rescaling , would need to see some logs of it to know better

The tuner (Delicious Tuning) has sent a third tune which I'm now trying. Still had issues with the high idle several times today but it didn't do the low rpm bounce/stall.

No codes. Stock MAF and using the TMAP that comes with the supercharger.
