I'm familiar with the site that's where I calculate my DA but from reading the stickied drag thread that's not how it's done here. DA is noted but your time is your time plain and simple. The top times from toothdoc and caymandiver are not corrected the way your stating.
Na, I understand that, we all post our bests, regardless of conditions. I was just saying to somewhat accurately gauge gains/losses of a modification, one should correct their times to SAE conditions to do a comparison.
I used to be an avid drag racer and it always irritated me when people would make wild claims about their catback, intake, *insert worthless modification* and how it dropped their ET by .4 of a second and gained 3mph. BUT in reality, the gains solely came from a better 60 foot and much better atmospheric conditions. BTW, I'm not saying you're doing such a thing.
ISF owners should really inform themselves about DA and also come to face the truth that some tracks are just faster/quicker than others for no scientific reason at all. I've raced all over the US and found this to be frustratingly true. The same even goes for lanes at the strip. One lane always seems to kick out slightly better ET/MPH than the other for no apparent reason.
DA has a massive impact on a car's performance, especially when the DA goes negative. It's free power and the cheapest modification out there

It just pays to be informed and it will take the sting out when most ISF owners realize that their car with the same mods is "only" going 12.5-12.7s@112-114mph with the same 60 foot, but at a different track and under more common DA like 1,000'-2,000'.

^^^^ I understand where your coming from and there are just so many factors to consider with how much a mod helps. One factor you haven't considered is the KCLV, which is huge when calculating how much a mod helps. I was just giving my opinion on the tune and regardless of DA I think it has proven it works very well.

I was wondering why this thread died....after learning about the low KCVL=low dyno numbers and finding a solution for this (reset again and re-learn the car with high load),i dont see anymore feedbacks if the car imlroved or still not.....any more results?

What are you guys using to monitor these values? I have an Android. What app and what plug in OBDII BT device?
One side question regarding the BT OBDII devices: can they run the Toyota/Lexus vehicle settings like the Techstream cable can do?

The only way to check the KVCL is with techstream on a laptop, Techstream related options & information wont show on basic phone apps. Phone apps are good for reading intake temps, timing ect.

Is the Transmission part fixed yet where the converter will stay locked up to the 7k or 7.2k redline without disengaging at 6800 with the tune??

Great numbers, Jason! Without the OBD handheld to tune the F, having the physical ECU tuned is the only option- and it works as advertised! For those that don't have the ECU tuned yet, it might not be a bad idea to purchase it and the new RR Racing intake together so you only need to have it retuned once. Outside of a SC, this is probably as maxed out as the IS F will get, which is more than what we as owners could have ever expected a few years back.

Yeah it wasn't that bad sending out the ECU. It was a bit scary but RR Racing has very good communication and their turn around time was ridiculously fast. I sent mine in on a Friday. They tuned the ECU and shipped it out Saturday. I got it back Monday.
Also, as what Brian said, for those of you who are thinking about getting the tune and are in southern cali, you should get the rr intake and tune together or you can just get the tune by itself. Apparently, RR racing will be able to tune the ECUs when they come for the Lexus of Escondido meet, so you don't have to send them out.
