I'll admit that I know next to nothing about ECU tuning, but assuming that you could tune it, what would a typical increase in HP look like?

Nothing is plugged into it... So that mean they currently didn't log anythibg thing...

They would also use a obd port for logging as well.

Well, a Stock 07 STI has roughly 238 whp 248 wtq.

Here are 2 links to Cobb's dyno results with there Stage 1 (stock with tune) and Stage 2 (DP/TurboBack) kits

IS F got D-4S as well. Ecu tuning still pretty much non-existent.

That's just a spot where the lower dash panel clips in. It's more obvious in one of the other dash pics.

on the lexus forums, so many IS350 and IS-F owners are furious that there are no ECU tuning solutions in the market today. On top of dealing with carbon buildup on high mileage engines.

Wings, could you post an appropriate link? The carbon build-up issue has me concerned.

Thanks.

i couldn't link you to one specific thread or website..its just all over the place. You could refer to join in the D4-S discussion here, http://www.ft86club.com/forums/showthread.php?t=1803 to get more insight/info.

early Carbon buildup is a common issue with any engine involving direct injection.

Entering these threads/discussions is like entering the Funhouse at the amusement park. Bewildering.

Wings, give me your personal take. Are you concerned about the carbon build-up issue? If so, how will you deal with it?

Again, thanks. (Post in that other thread, if my question is too OT.)

From what I read from the other posts, it seems like the D4-S seems to reduce if not solve the problem with carbon build up. The port injectors basically clean the buildup? Correct me if I'm mistaken.
