It's -2 here in Toronto. Cars driven in this weather feel like turbo supercharged.

A few questions. Sorry been out of the isf scene but i would have to take my ecu out n mail it to u then have u map it n sendit back? How do u deal with the climate change on where people live? But my main question is how much n whe will u be finalizing the sc? I want both asap. I can deal without my car since i hardly drive it

Cannot give an exact date for the SC, but if everything continues to go to plan, then it will be formally introduced in late spring or early summer.

Regarding differences in climate, we try to simulate hot conditions by dynoing the car with the hood closed (you can see this on our dyno results). When we dyno with the hood closed, intake temps reach 120-130F. Of course, there are limitations on the dyno which is why we track our ISF so much. As I have mentioned before, if our track program (starting in March) identifies any deficiencies that need to be addressed with the tune, all essential tune upgrades will be free.

Yes, you need to remove your ECU (there are some tips on removal on here), and send it to RR-Racing to remap. I believe they are still trying to turn these around in just one day, which is frankly amazing!

You also need to decide on your options when ordering from the website. In addition to listing your mods, you need to decide if you want to up the rev limiter?

Best of luck.

Any supercharger hints?

MileHIFcar

I don't think he has released details yet of what type of supercharger it's going to be? But rest assured I'm guessing traction is going to be the first thing that comes to mind with this supercharger (as in lack of traction lol) with 600+ from what I heard.....

So what are everyone's thoughts on raising the rev limiter? For me, I don't really drag at the track much, but mostly highway pulls and the such. Should I stay at stock limiter?

Here's the link: http://www.rr-racing.com/RR-Racing-Lexus-IS-F-ECU-Upgrade-Tune-p/isftune001.htm

Don't forget the introductory discount code 'IAMTUNE'. Should drop the price $100 if still available.

Good luck!

I will keep mine stock I think.

Not going to use it much, or get the benefits with mostly fast road and the occasional track day.

Can always add it at a later date? Can't say it's a priority for me.

Rafi,
What are these intake updates you speak of? Is it an additional add on to your current intake tube?

One thing I have noticed, and I'm not sure if others have as well, but in cold weather (20-30 degrees F) my F would usually start up and idle around 1600 or so RPMS for the first 15 seconds or so. After the flash, cold starts seem to idle lower, like around 1200 RPM right after the engine starts. I wonder why this is?
