Performance Chips
I have a 2006 AWD IS 250. I love it, but think it is lacking a little bit in the horsepower department. Does anyone know if there is a chip I can buy to give it a little extra boost? Or if not, what other modification I can make to help it out? Thanks.

Besides that, anyone claiming they have a chip is lying. It isn't possible to remove and replace any chip in a Toyota/Lexus/Scion ECM without doing some precision soldering.

I'd like to see something that would improve throttle response, and reduce the amount of throttle "hang" while shifting. Power gains are very much secondary to me, as these other 2 annoyances are doing a lot more to keep me from enjoying the drive.

The Dinan chip for my Integra required an ECU swap. Dinan replaced the stock chip with a socket, then sent the socketed ECU with a copy of the stock chip and a copy of the performance chip. After installing the modified ECU, the original ECU was sent back to Dinan. Still not worth it...

I read about a HKS clip that will do the New IS, I wanna improve the gear shifting, you know if you shift up a gear in S mode the respond isn't that fast... I expected the IS gear box are more like the one on MR-S (MR2 Spyder)... When I dirve the MR-S in Sydeny I like the gear box so much...

I know there are intake system, header and exhaust system for improving the 250 performance. But for around $2k, IMO 10% hp increase doesn't seem a good investment for me. I was thinking about if there's any performance chip out there for the new IS too.

Yeah, I have a stack of Supra ECMs on my shelf, and one of them is a G-Force (now Technosquare) modified unit with a daughterboard, secondary ECM and PROM. The nice thing is, it has no boost limit, raised rev limit, and no top speed limiter. The not nice thing is, I can't change anything in it without paying a small ransom (~$500) for a "new" program. I have no desire to do that again. At least I bought it used and didn't have to pay the $1350 + permanently modded ECM G-Force was asking to do the mod.

Toyota ECU's are well engineered. There is no company out there that offers a "chip" mod for Toyota. Toyota ECU mapping is nearly impossible to decode unless you have access to Toyota or TRD's resources. That is why many import tuners go with Honda, because they are easy to modify. Toyota/Lexus however is not.

Yeah, I know all too well. I've been trying to find someone at Lotus who'll be friendly about sharing the code, but so far no luck. At least the Elise/Exige is tuned nicely and it's a full Toyota drivetrain with Lotus's engine code.
Even just a correct checksum generator would be really cool...
