As stated in the general thread...what did I do To my FJ....
fitted a Raptor Engine and Transmission ECU flash to Bozo yesterday.
Coupla extra bits of info to try to centralise info.
1. This ECU flash has been developed DU by Raptor, for the Dual VVTI 1GR engine, for the plus 2010 models.
2. No affiliation with Raptor, just a happy customer.
3. 4 tunes available.
stage 1 - stock FJ running 91 RON gas
stage 2 - modified FJ running 91 RON gas - mods to airbox and exhaust
stage 3 - stock FJ running 95 RON gas
stage 4 - modified FJ running 95 RON gas - mods to airbox and exhaust
DU, we have 3 levels of fuel
standard ULP = 91 ron
Super ULP = 95 ron
Premium ULP = 98 ron
Not sure what or how that relates to US gas.... ( we also have ethanol blends etc)
4. Measurements are in kw HP, not BHP.
5. Test and development FJ was a 2011 bone stock AT.
6. 1 method are offered by Raptor to obtain the flash....
buy the Powergate 3, pull your stock DAT file off the ECU, send it to them via email, they will modify the file and send it back to you with flash... upload this to your ECU ...done .... you have the ability to switch back to stock at your will as you have two DAT files, stock and modified.
7. The modified DAT is locked to your vehicle, as is the Powergate, so you cannot share it across other FJ's.
I'm not a dyno expert, and have no real knowledge how it all works .... but my butt o meter, tells me it works.
so if you have technical questions about AFR, roller size, type of Dyno used, etc..... you would be best emailing Raptor directly and speaking with Tim.

For those into Fakebook there is a large thingy page all about the 1GR called Toyota 1GRFE Club
Alot of info in there, apparently.
In the real world, after just one test drive, this flash ...absolutely rocks ... the power and performance increase and smooth gear shifts changes the FJ from a puddy tat into a Tiger.....
what I like is that this flash changes the transmission ECU parameters too.... so its matched to the engine enhancement.... the A750 is no longer lazy .... it really makes a huge difference to the A750......
Here is the dyno result from the Stage 3 flash, stock FJ and 95 ron.....
4th October 2019 UPDATE
Since writing this thread in early April.
Raptor have simplified the available tunes.
Currently they offer
1. All Fuel Tune
2. Highest Octane - Racer performance tune - called the 98 Tune
Airbox mods are recommended with both tunes, but testing has shown exhaust mods do not seem to indicate any performance increase.
