SARD Japan IS350 ECU Tune = 40rwhp gain!
I was on the IS-F forum reading about SARD Japan providing an ECU Tune for USDM IS-F owners:

Earlier today, some dyno sheets were posted on RWHP gains for JDM IS-Fs with the ECU tune. In addition to those graphs, there was one dyno sheet posted of a SARD tuned JDM IS350:
Any thoughts on this late breaking development?

SARD is legit as far as I know. But I also know a tune on a JDM ecu doesn't work with our USDM ecu. It may be simple for SARD to reprogram for ours? Not entirely sure. There were posts over a year ago for someone to send sard a USDM ISF ecu so they could get that going and I don't believe it ever happened. (Edit: sorry just saw link)

Guys, after reading Nigel's posts who is the middle man for this, THERE WILL BE NO ECU REFLASH FOR ISX50. Ever, from SARD. (He has since edited/removed post, or i cant find it again?)
SARD does not have the data and does not wish to tune the ISx50.
To be honest, based on the 7-12% gains the ISF recieves from the SARD reflash, we can manage nearly the same with MAPECU3. I believe 06isDriver piggy backed his NA is350 and managed to pull some 12-20whp? Not sure on exact numbers. Issue here is it's not "easy". I still need to find someone to help setup mapecu3 on my boosted 250

The following is from post 49
Much as I'd like to see this for North American cars, it doesn't look likely
No, they will NOT tune the ISX50.
They do not have the data from toyota and dense for the US Spec ISX50.
So they cannot tune anything beside US Spec ISF.
We only focus on the US Spec ISF ECU in this project.
If the ISF goes well, then we might consider RCF to be the next car.
If the ISF doesn't go well, SARD will never do it again.

Information base on experience from SARD Japan and some JDM IS F and IS350 dyno sheet.
We do NOT have any USDM ISF dyno yet, please understand these information are given by SARD Japan.
Each car is different and it will have different result.
So far 30-40 gain from stock ecu on these dyno sheet
