How Much Power Will a RR-Racing ECU Tune Make on My Lexus ISF?

[@EatSleepDrive]

I've seen a bunch of comments regarding "you have to drive the car after the tune to bring the correction factors back up." We did that, you just didn't see it on the video. The instructions state that you can drive it 50 miles OR do repeated 4th gear pulls. We did over 10 pulls and then a cool down before we started logging the new numbers.

[@Danu01c]

Get used to it. The majority of the F community is a RR nutswinger that bashes you if you show that you really didn't gain much or anything from RR tune.

[@chibba5418]

yeah, you also didn't dyno in manual mode with the tune which is why you didn't hit 7200rpm. RR tune isn't supposed to show massive whp/torque gains (I don't know any plug-n-play OBD ECU tuner for an NA car that does, even Ktuner/Hondata). RR Tune's gains are in the extra 500rpm of peak hp (removed rev limiter), removal of speed governor, throttle response, and with other mods, as well as the small whp gain. With the Intake + Exhaust + Headers + Tune, you're looking at ~50whp gains, which is pretty damn good for some bolt ons on an NA engine. I'm no RR fanboy (I don't think they'll ever get my business again) but I give them credit for cracking the uncrackable Lexus ECUs

[@Danu01c]

@@chibba5418 You can custom tune with OV tunes software or as my is350, with bitbox. My car currently makes the same numbers as a FBO RR tunes IS350 with just invidia midpipe and manzo cheapo axle back and the custom tune of course (293whp 282wtq)

[@chibba5418]

@@Danu01c OVTune isn't around anymore for the IS350 as far as I'm concerned. I would've loved to bought OV for that extra 200rpm tbh. And RR actually shows similar gains with an intake, exhaust, and tune (to what you have shown me)

[@Danu01c]

@@chibba5418 OV tune isn't gone. They don't tune anymore nor offer reflash. They literally made a software to tune the ISF/RCF/GSF. The only people tuning with that software right now is delicious tuning and from one of the results I saw on one person they gained like 18whp in a RCF or I can't remember if it was more but it was on 91 octane. RR tune simply sucks. Just a raised limiter and a little timing and that's it. Oh and it adds the converter slipping "feature" at the end of each gear 😂

I just bought the tune 2 weeks ago and I got to say its worth it. Feels like a whole new different car in sport manual mode. felt a dramatic increase in the low and mid range power and shifting is more aggressive in first and second gear.

[@gabeh7373]

The tune works especially the mid-range is improved. I have an FBO ISF and the dyno will never show the potential of the ISF at real road speeds. Any Dyno that I've seen or been at doesn't replicate the correct and real-world air flow at highway speeds where the computer makes adjustments through the MAF sensor on the ISF. The ISF is super finicky with air intake temps and therefore shows its full potential on the road where cooler temps are recognized through the MAF sensor and therefore you get the proper adjustments in your timing curve from the tune.

[@gabeh7373]

And to piggyback on my last response the true potential of the ISF like others have stated is with a set of aftermarket headers either PPE or Sikky. The stock manifolds suck and it's like the motor is trying to breathe through coffee straws

Another great video! I'm about to buy an RR Racing tune for my 2010 IS350 Sport, it will basically move redline to 7200 RPM giving me an additional 15 to 20 whp. I'm currently at around 287 whp right now. I don't really need more power, I personally think what I have is sufficient, but being able to move redline to 7200 RPM for some additional power when I need it is awesome. Keep the video's coming!

[@EatSleepDrive]

Thanks! Enjoy the tune on your 350 and the extra revs.

[@valdaviper1]

Fan of your channel because I had an 08 and currently a 12 ISF, but I think this is the first video that should have been done a little better. The RR Racing tune recommends you to drive 50+ miles or do steady pulls to bring the KCLV back up and for the computer to learn and adapt. Normal KCLV on a well maintained ISF is 21-25, higher with a little bit of octane booster or gallon of E85. When you reset the battery or rewrite the software, the KCLV usually drops to 15 and has to rise from there. The higher the KCLV the more power you have, and it's also a good indicator to see on a higher mile ISF if the car is having any other issues such as dirty MAF, clogged air filter, old plugs, bad fuel, etc. I had the same tune on my 08 ISF with just a borla, and on my 12 with PPE headers and Borla and current XForce Varex exhaust. I never dyno'd, but roll racing or passing on the highway, the tune is a noticeable improvement with no downsides.

[@EatSleepDrive]

The instructions state. Drive 50 miles OR do repeated 4th gear pulls to get the correction factor up. We did the latter, you just didn't see that boring part in the video.

[@valdaviper1]

@@EatSleepDrive My mistake then, watching the video it just sounded like you guys dyno'd, uploaded the tune, then started it, and put the fans back on to dyno. Let us know how it compares over time! KCLV also has a below 3k and above 3k metric, so the driving would help more than just steady pulls. The biggest increase is in the mid range which I think people will read past and just compare max numbers. For what it's worth I think their tune is good, but the tuned intake is not worth it. Have had both. Looking forward to more progress!

[@AbsolutMassager]

My IS350 made 15whp and 15wtq gain just by replacing the secondary cats with test pipes. Dunno if you’ll get that boost on your ISF but def worth considering too.

[@ImSoHuhj]

Did u retune it?

[@Danu01c]

I get rocks thrown at me for saying that their tune is really just a little adjustment to mixture and timing. Yet in every dyno video its proven that the changes are minimal.

[@SniperReady]

The VW Golf R tune goes from 292hp/~290tq to ~360hp/~380tq on 93. It's true it is just timing and mixture, but for turbocharged vehicles or any other forced injection, really, a tune can get you a lot of extra power. I timed a few launch control runs, and with no tune the car hits 60mph in about 5.0 seconds. With the tune, it's about 3.8 seconds. That's significant for just software.

[@Danu01c]

@@SniperReady yeah.... But if cams are tweaked you get a lot of power out of it. For example, my is350 went from 263wtq to 282wtq from one pass to another by just touching the cams. In a ISF there should be similar if not more gains. Their tune for the is350 doesn't do shit. Just higher limiter that's all. I literally make the exact same power and torque as a FBO RR tuned is350 with just a invidia midpipe and a cheap ass axle back that has the same tube diameter as stock and a custom tune.

[@25kwh]

Good content, man; however, this one is a bummer... 9hp for $600? What about torque? Seems like no gain as you had more variance in heat soak at first run.

[@chibba5418]

gains come from the extra 550rpm of peak power (rev limit removal), removal of speed limiter, and improved throttle response, in addition to the 10whp/10lb-ft gain. RR charges high prices because they are the only company that can crack Lexus' ECUs.

[@thepepsimaker]

He need headers

[@saularevalo4477]

Toyota is backwards when it comes to the way it controls the ecu timing, so the knock correction value (kclv) will be at 0 when you first reset the ecu. To get it to the highest point you need to do at least a few 5th and 6th gear low rpm full throttle runs and the ecu will start correcting and you will gain a ton of power. I also recommend a blend of e30 in it so the ecu will have even more breathing room.

Dealership experiences will vary. Legally speaking they'd have to prove the modifications contributed to a failure, which you never now how that will go. These engines are known to be pretty reliable regardless so it's unlikely you'd encounter an issue, but of course it's a risk none the less.

[@VersanGetryx]

I wouldn't mess with it until it's out of warranty. You don't need to play that game with a dealership who would try to blame everything on the tune, as EatSleepDrive noted. Enjoy the NA engine as is, maybe with a bit of exhaust work :)

[@bronxtaskforce01]

For what RRACING charges for the tune it's not impressive on a NA engine..

Anyone know where to get pulleys for a IS 250?

Thinking of buying a ISF but I'm afraid of the valley plate leak. Any things to look out for before buying?

In the rally world guys spend thousands to gain a second no big deal spending to get what you want ..

[@Degreez33]

I don't understand why your calling it an ISF. they don't stock with over 415hp. your cars is making 360

[@EatSleepDrive]

I think you're confused, crank horsepower and wheel horsepower are very different..

[@tleoipl37]

Bro don’t know about crank vs wheel HP😅

[@jacr6521]

So 416hp at the crank and 350ish at the rear wheels

[@awdx4g63]

$700 for 10 hp? how can you be happy with it?

[@CSOCSO]

you could spend just as much on a fancy looking penis whale intake system or twice as much on exhaust and they wont give you more hp than that (each)

[@chibba5418]

Toyota ECUs are hard to crack... this isn't Honda. A 10whp gain from a plug-and-play is pretty good Also, he didn't have the car in manual mode, which means the rev limiter was on

If you sold 4 cars are you into something bigger ?

[@EatSleepDrive]

Maybe....

[@101TheKMan]

What’s the throttle response like? Is it more responsive or the same as stock?

[@Jcruzcaptures]

That’s the main thing for me, throttle response on ISF is terrible

[@k_s.m]

10hp gain on stock 353power is less than 3% . Shouldn't be even noticeable during the ride...That's more like within a tollerance error than a real gain tbh.

[@georgeobongen2900]

Get an updated front and rear bumper then more exhaust and engine mods

Please dyno with k&N and Injen intake! They claim to increase 20+ HP

Injen and k&n actually rob the engine of power a drop in afe filter and hps elbow is a better option

K&N filter with stock intake is better and PPE header, exhaust 😎👍

At 1'32": For NA cars it is MUCH harder!

[@johncanale3454]

How come they didnt dyno with the hood open?

[@777aterial]

A closed hood gives real street values.

[@EatSleepDrive]

Do you drive down the road with your hood open? The three fans placed in the front simulate airflow while moving.

[@johncanale3454]

One could argue putting a dyno in a wind tunnel would be better. Not 3 fans. Lol

Thanks for doing this test. I think it's way too costly for an 8 hp gain.

[@valdaviper1]

8whp, and most of the gain is in mid range where it's most beneficial. The Borla/Joez cost $1200-1600 before and added 15-20whp. $1800-2800 headers give 30whp or so. The gain seems right for the $ on an NA platform.

[@Midwest..]

Best combination K & N filter, PPE header, exhaust, RR Racing Tune will gain more then 8 hp 😎👍

[@Fee.1]

Welcome to our reality for literally 99% of cars for literally 99% of our lives. We paid THOUSANDS for 8 measurable horsepower across the rev range in the 90’s 😂

@@Midwest.. what do you think of the takeda intake?

[@mudachuka12345]

@@Midwest.. k&n filters are shite the oil on the filter coats the maf sensor and start to throw up eml light and won’t read the airflow temp and flow correctly one of the worst modifications Iv done to a civic type R. If you just fit a performance filter use AEM dry filter. You’re lucky if it will make 1% improvement letting in dirty air that leads to valve seat recession. Filter companies won’t mention that. Best is stock factory filter. So the maf doesn’t receive dirty and oily air.
