Can RR racing tune make RCF pop and crackle?
#16
#17
Im thinking about getting the RR racing tune for my rcf i see it listed for $499. Does anyone have any experience with getting just the tune? All i have done is the resonator delete and i dont want it any louder due to my commute. Is it worth it without H/I/E. Is this possible? What are the power gains for just the tune?
thanks for your feedback.

I can appreciate an aftermarket exhaust all day long, but the whole pop/bang/crackle thing is not appealing to me at all personally, so I'm genuinely curious as to what the reasoning is behind why someone would want their car to sound like that?

Yes, I believe RR-Tune asks you for what type of setup you have on your car (stock, E, I, I/H, I/E, I/H/E) Since resonator delete is pretty much stock, you will select stock from the drop down and then they program the tune they send you according to stock parameters.
i checking on rr racing website and no power gains were shown do you the power figures?
also how does the process work? Do i have to remove my ecu and send it to them? If yes are there any instructions on how to do so? Im assuming the car needs to sit until the ecu is returned?

I believe, you get some sort of a console that you hook up to your OBDII port and then you install the new ECU programming. I don't believe you swap ECUs or send in your ECU. The plug and play allows you to go back to stock tuning when you take to the dealership. Again, you can PM Rafi at RR engineering as he can give details on it.
p.s. I also don't understand the crackle and pop obsession either. My Invidia crackles a bit on cold starts and pops when I hit the rev limiter, but idle is smooth once warmed up and I don't think pops and crackles suit the character of the RCF.

We do not do a pop crackle snap tune. Reason being... Have fun destroying your engine. Our tunes are optimized for power gain + reliability, because that's the reason you bought a Lexus.
Popcorn tunes are literally dumping unburnt fuel and detonating them for the pop pop bang noises. But it does cause long term damage to your engine in doing so, along with the fact you do not gain any performance from it.
The smart way to do it is have a free flowing exhaust and you will achieve the same type of thing. Headers, exhaust and a REAL tune will give you the crackle of a performance car.

Peak power gains are fairly minimal on the RCF with the tune. However, it really changes the curve of the powerband. You will get a much "thicker" powerband where there will be more area under the curve near the midranges where you will have more available torque/power. However, once really wind out the engine to redline, the peak will be only a few whp more. However, more area under the curve means better performance as you have a broader powerband.

That would be great if they can send the console to me, but I was referring to the instructions here which says to ship them the ECU. wondering if that's still the case?

They do seem to be trying to address things they heard from the RCF reviews in the Supra if you listen closely in the videos with the engineers. They are very proud of the exhaust sound.

Waste fuel, ya. Cause extra wear on cats and other emission system components, sure. Ultimately lead to something catastrophic before you have a chance to identify a failing part and replace it? Probably not.
I would love for someone to offer an in-depth explanation on how an overrun tune would destroy a motor. I’m also wondering if anyone has personal experience, or has ever even read about a burble tune destroying a car.

While I fully comprehend that burble tunes, over time, will likely result in ‘premature’ wear, I fail to understand how one would “destroy their engine” doing this.

So wait, it sucked the cat all the way back up the exhaust path into the engine? I've heard of pre-cat destruction killing turbos since they are after that part but the cats on a 350 should be well downstream of the engine and only sending gases out. Please correct me if I'm missing something.
