Looking to add some more power to my RC300 ,after reading this forum came across this RR RACING LEXUS 3XX OBD ECU UPGRADE TUNE


Anyone do this?

Bump


Looking at doing this tune as well.

Wish they'd lower the price a bit so I can get it sent to Canada!!

I've been wondering the same thing! I wouldn't mind squeezing a few more HP from my car, if it's legit. The deal with the ARK exhaust, headers and tune for a bit over $2800 seems like it's worth the cash.

Well I've been reading the reviews. Looks legit. And just a tune will bump the rc300 up about 35 hp alone!
same damn engine in the 350 just detuned.

I am very very interested in doing it for sure. Revs higher to 7200 rpm and delete the speed limit all in one!

I would also like to find out if anyone has installed the tune, I spoke to RR Racing about it and asked them if the car would still pass emissions, void warranty (if the dealer could find out if the engine tune was altered), and if the powertrain would have any adverse wear from the tune. It seems the car will pass emissions fine, the dealer will probably not figure out that the tune has been modified, will not void warranty, and it should not affect the powertrain as it is the same as the RS350 AWD.
Sounds promising! But I would rather hear from someone that has installed it!!

I've been reading up on all the forums I could get my hands on.

Firstly, just before doing your emissions or other government regulated tests, you can just advert back to the stock build and de-program/uninstall the tune up. When done, you can reinstall it back again if you want.

the lexus IS and the RC have the same engine I believe, so read up what other users have been saying about the power gain.
I want someone to comment on fuel efficiency. The rc 350 already has better fuel economy than the rc 300 ( believe it or not) so getting this tune might do the same if you are an rc 300 user.
If you are a 350 user than you will get that immediate 10hp boost and wheel horse power is much more than 10 hp( I think it was 10Whp with a stock car, more if you do headers, exhaust ). I want PHOTOS!!

And more importantly. Id like a GROUP DISCOUNT!!! bcuz the company SAID in a few posts that THEY WOULD do it in the spring.... WHICH IS NOW

I am highly interested in this as well. I have been watching the IS post following users and details. Right now it sounds like the '17 models are SOL until they come up with a workaround. I am currently waiting until my first oil change before i go ahead and do this. However even at the $500 cost that is by far the cheapest upgrade to our cars for HP out there.

Its legit.. Many proven uses on the ISF community as well..

How much for lexus rc 300 and how much for rc 350.

Do you have a website.
I can't private message yet.

This is the only tune that I would trust myself:
http://www.rr-racing.com/RR-Racing-L...ig3xxtne02.htm

The owner is all over the IS and RC vendor pages and quick to respond. As I said before if you have '17 send them a PM first and make sure its going to work.

I just want to see ONE VIDEO with the RR tune racing 0-60 or 0-80 side by side. a
TUNED lexus rc 300 vs STOCK lexus 350
or a TUNED lexus IS 250 vs STOCK is 350
or a even a tuned lexus IS VS STOCK lexus IS
or TUNED lexus rc 350 vs STOCK lexus rc 350 ( or whichever model of the rc vs that same STOCK rc)

it seems to be a HUGE flaw in their marketing because that is what a lot of us want to see, instead of numbers on a graph.

and I've searched the earth to find just 1 video, all i keep seeing is LEXUS ISF but nothing with other models vs stock same model

My ECU tune is on the way! I went with a package of an ARK exhaust and the tune, and the pricing was very reasonable. I will report back once everything is in and dialed up. My only hope is this brings my 350 AWD up to speed with my previous 08' IS350.

and3re

Awesome news.

Are you currently in the Rc350?

And what was your previous 08 IS 350 PUSHING before in terms of HP.


Report back as soon as you get it to let us know Results.

The IS was
​​​​​​ basically at stock HP with fsport intake and exhaust. Being that the RC350 awd has the same powertrain, but is 400lbs heavier, it definitely feels no where nearly as quick.

Do you think you can do a 0-60 run with stock and one with the ecu tune? Sounds like a lot of people on the forum wants to see something like that (myself included). Would help greatly. Thanks!
