Call me crazy but that looks meh

I like the fact that the fuel cut is much higher. however that torque dip is ridiculous. that's the whole purpose of having it "tuned" to get rid of that. Either your friend is not a good of tuner or this is not a actual "tune".

That's the tuner email and what he can do with Lexus ECU



Dear Meshal,

It is possible to tune the Lexus IS-F & is350 on stock ecu.
Power gains vary from car to car but the range would be between 10-25whp.

The parameters that can be adjusted:

-Fueling
-Ignition Timing
-VVTi Adjustment (Intake and Exhaust)
-Rpm Limiter
-Throttle Response (for a sharper and faster response)
-Improving fuel consumption (depends on the car, some cars run great on a stock tune)
-Check engine disable for specific codes (good for those with headers, there is no need for simulators)
-Rpm shifting while in Automatic "D" to change at a higher rpm, and in near future a full transmission tune.
-Also if someone has headers and likes poping sound while decelerating it can be done as well.

let me know if you have any question.

Removal of the speed limiter is a good thing. What's the actual speed you can reach?
Although, that torque dip looks pretty bad. Pops and crackles are a bit too much for a V6 Lexus imo. But, if you like it then it's worth it.

Thats what the tuner said

I did race x2 Q50 yesterday

Finally i did understand what yall mean about the torque dip !! The dyno in Saudi Arabia did run it though 3 gears !!

Thanks for posting up the results Mesh704!

It looks pretty promising! The accomplishments, whether the results were big or small, is nonetheless a step in the right direction.

Keep posting more details as you get them.

I dont understand why he would do that, but do you happened to have a rpm graph?

Mesh704

I'm going to change my cat back then I will run it again on dyno through one gear !! Maybe the 4th or the third gear !!

The new cat back will be for the mid-pipe straight pipes with X )

For the axle back will be : ( Fox muffler with 4 tips )

Guys believe me I really can feel the different the car response fast !!

Mesh, your IS is way faster than mine. I remember racing my friend in his Q50S and I wasn't able to keep up. And that car wasn't even broken in.

Mesh704

Forget about the new cat back LOL

I did bought KOOKS mufflers 2.5 for the axle back instead of Tom's !! I will have Tom's tips on KOOKS mufflers!!


So my set up will be ;
- PPE HEADERS
- Invidia mid-pipe
-KOOKS axle back
-AFE magnum force cold air intake

I will have them installed tomorrow and hope they sound good and have better performance!!

Mesh704

Thanks man

You should go to @dubike_dyno and tune your car my friend !! Believe me you will love it !!

We are not doubting your car is faster or gained more hp. We are just trying to figure out if it is a legitimate tune or one of those flash kit. And only we to see that is through the dyno graph. If your friend truly cracked the Lexus ecu, he would be the only aftermarket tuner that has done it. Which could make him into a millionaire over night.

We are just as excited about this as you are. We just want more detail of how he has done it as many have failed and produced useless flash kits.
