Hi all,

has anyone done any tune to his IS00? I recently came across complete E-Tune Kit by Loi for $1500. The TunedByLoi Complete Remote E-Tune Kit allows to unlock and flash your IS500 with custom tune map. They say you can always revert back to stock if you want to use your warranty and this mod will not cause any engine light or emissions passing issue. Just wanted to ask if anyone has done similar and if there is any cons.

the mod will add around 25hp and 30 to the torque.

Thanks

Hello and welcome.

I suggest you check out the following thread - https://www.clublexus.com/forums/is-...ight=tuned+loi

It has a lot of information on the tune by Loi. Does that help?

I was the first tuned IS500 in person with Loi. It’s a noticeable difference. Have about 5k miles on his tune and has been great, no regrets. I tried flashing back to stock to see if I noticed the difference and it was very noticeable.

Have you had check engine light on? Would you pass emission test whenever you need to do it or you have to flash it back to stock to pass?

Pandonsf

no check engine lights. Believe you’d still pass emissions. We have 8 years on new cars out here before we have to worry about smog checks.

Thanks! Did you do remote E tune kit or did it in the shop?
How did it change your gas usage ?

thanks

tuned at the local shop he tunes out of in the Bay Area, mpg is about the same.

Got it thanks. I don’t have the confidence to do it myself.
