I was going to advise showing the TSB on the rear low pressure fuel pump until I read the end of your post. Good thing it has been resolved and they reflashed your ECU (or probably changed the fuel pump).

He said he owned 2 lexus himself and they were all loud at some point. I was amazed this guy was still working there. Trying to turn customers away like that. I've had a GS and LS myself and not one had a loud fuel pump that you could hear like a race car hahah. I made sure to tell him that I have had other RCF owners tell me its the fuel pump and it just needs to be reflashed. He took it as if I was telling him how to do his job but i was just informing him so that the tech could maybe narrow down his/her troubleshooting. Little to my surprise when we took the car home no more fuel pump sound. hahah goes to show you why the service attendant was behind the counter and not behind the tools in the garage.

I’m confused. Did it just disappear or did they reflash it? If it just disappeared on its own it WILL come back. AMHIK.
If that is the case, best bet at that point is to record it, take the tsb to Longo and make sure they do it (have it noted on your paperwork). It’s obvious the service people and Lexus of El Cajon are not familiar with the issue.
I was able to get it flashed that day. Noise is now gone.

Shes the white RCF at the end. Lowered on coilovers and fully tinted including her windshield. We'll soon be doing a chrome delete to the windows and front grill.
Wife has started modding, well actually i have hahaha. love this platform!
Thanks Rolla, We got a good deal from our friend we couldnt pass up. The coils are made from ARK. I was hesitant at first because i've never heard of the brand but after seeing them, they looked well built and not leaking. I got them for less than lowering springs. We couldnt be happier. Honestly I dont think she wants an exhaust just because she doesnt want to be hassled by cops and its too expensive haha. Since the RCF platform is good as it is already, she would be more into cosmetics more than anything.

Good to hear it all worked out well for you. Keep posting updates.
I noticed today after driving it that when in manual mode and standard is the only time it rev matches. When i go into sport or sport plus the tranny feels lazy and doesnt want to rev match? are there any settings i need to change?

Did you have the car properly warmed up? The transmission is seriously "detuned" unless the car has been properly warmed up, which is around 15 minutes of driving. I use Sport+ almost all of the time and it rev matches every time it is properly warmed up. Even 2nd to 1st rev-match while coasting to a traffic light stop, is quite dramatic so to speak.

You should absolutely be getting the rev-matched "throttle blips" when downshifting in sport plus mode, not to mention you should feel a very noticeable and obvious change to the speed of the transmission shifting when at full throttle. It also holds much higher rpms when in auto mode while in sport plus.
Basically everything should be the exact opposite of what you're saying you're experiencing. That's totally strange. Nothing about the car should feel more performance oriented while in normal mode. If you are sure your car is getting lazier and more docile in sport plus, something is wrong. There's nothing in the settings that I'm aware of that can essentially tell the car computer to reverse the modes. I know you can change the display screen in the dash, but that doesnt sound like what you're talking about.

hmmm it’s not consistent. It does do it sometimes when I’m hard on the brakes. Maybe I’m just used to my bmw always rev matching every time I downshift.
No matter in comfort, sport, or sport plus.
Maybe, make a small video of it downshift from 3rd to 2nd at around 4500- 5000 rpm in sport+/manual mode. In theory, it should blip very hard. It made my wife jump out of the seat a few times because she did not expect it. It will make it easier to see how it behaves.
Not to hijack the thread but I am also looking to get an RC F in the near future for myself. I would use the car both as a daily and as a track car. The forum says these are very reliable and this thread includes good info on things to look for and TSB's. However, there is one thing I haven't been able to find: has anyone had issues with TVD? Since I will be tracking I have always considered looking for an RC F with TVD, but I'm looking at a 2015 car that is out of warranty and the TVD is mighty expensive, so my concern is if it can withstand track duty. For full context, I'm currently looking at a 2015 RC F with 50k mi, premium + navigation/ML audio + performance packages and the tri-beam headlights, white exterior, red interior for ~41k. I've been looking for a while and it seems a reasonable price given that I'm located in Northern California and the car is here as well. Of course a lower mileage/newer MY would be nicer but I'm working with this budget so I have funds for track days + wear items (brakes, tires).
