Why No Piggy back for the 2GR

I am interested in finding out why there are no piggy back ECU systems for the 2GR Engine. Is there a reason, theses engines are amazing, to make in excess of 200KW good fuel economy and is super light. plus The Aurion is marketed as a performance family car (like the falcon and commodore).

Any one got any ideas?

There are piggyback ECU's that can be used on the 2GR-FE. eManage and Haltech are a couple. Even stand-alone ECU's can be wired as a piggyback as required. It's not actually a question of why there aren't any, but more of a question of why it's not widely done and documented.

Simple. The Aurion/American V6 Gen 6+ Camry is not in the right market to warrant having a group out there who have gone to the effort and release plug-and-play solutions for it. At the end of the day, it is simply just a family car, not a sports car. Also, the large amount of people who would rather get a plug-and-play solution rather than pioneering a solution is what leads to no development occurring.

If you are after a plug-and-play solution, this is about the closest you will get, but there aren't any promises that it will work with the Australian Aurion:

Through Money Wrench racing you can buy the GReddy Emange Ultimate and harness to the 2GR-FE, just nobody has fitted one to the Aurion as of yet that we know of. But hay feel free to pioneer it for us lol

It's hard to say whether a piggy back would be worth it. I spoke to chiptorque the other day who mentioned they heard of a TRD down in Melbourne that had installed such an ecu and the gains were minimal.

Even with a few mods such as exhaust and intake (the only 2 mods we can really do anyhow) I think the Aurion is already in a pretty high state of tune

That said, the ECU ChipTorque deals with is the XEDE Processor. I would imagine that the eManage Ultimate would have a higher level of adjustment that may provide some gains.

Speaking of e-Manage Ultimate; how intelligent is the 2GR? The Viking (plus multiple tunerrs) have said the e-Manage Ultimate won't allow for optimal tuning if i went to 6psi on my 1mz.

Given the technical advances of the ecu... how restrictive would the emanate be when paired with the 2gr?

The link G4 xtreme and Vipec V88's have been used successfully on the 2GR's, in both NA and supercharged trim. If you had cash to burn you could make a plugin adapter to run either alongside the stock ECU so your dash etc remains fully functional.

Or just rip the 2GR out and put it in something RWD and get rid of the factory ECU completely ;)

Green line is NA, purple line is after the addition of a TRD charger shipped from Aus:

Anything where you can fairly compare apples with apples (with and without piggyback on the same engine)?

you will get SFA gains from a traditional piggyback in conjunction with the stock ECU. The stock ECU will learn it's way back to toyota's optimal fuel and ignition trims.

You need to take the stock ECU out of the fuel/ignition/vvt control equation if you want to push the limits.

      New Vehicle Key Remotes

      I've had 2 services and still no 2nd key. Service has no idea and says talk to sales. You'd think they were separate entities. Its nows 14 mths and still nothing. On delivery they gave 12mths roadside assist. That's ok except i had 9ths left on my old car that got trasfered and couldn't be pro rated. They didn't extend roadside asist when there was still no sign of key. If I could get onto Toyota I would but like delivery times they push you onto the dealers.... hopeless!!!

      Help with Head unit Upgrade ?

      Hello there, I have just purchased my first car, a used 2013 Corolla ZR Levin, wonderful machine !!!!!!! But the entertainment unit is a bit dated (see photos), i was interested in upgrading to something with Android auto (probably DIY). But i have no clue how to go about finding the perfect system that'll fit in the dash. Also, if there could be a USB-C connection that could be cleanly mounted into the blank spot next to the heated seat controls to run the unit directly from phone, is that at all possible? Can someone please provide some ideas as to how i might get this done, or if it is even possible............... Thanks fellas

      update Peter Kittle diagnosed it as a Transaxle noise and they submitted an out of warranty claim. Toyota Aust honored the claim and replaced the transmission(transaxle assembly). My diagnostic fee was also refunded. Thankyou Liam at Peter Kittle for listening and responding to the issue.

      Part Wanted for 80, 100, 105 Series Landcruiser Spring Cap

      Hi, I am trying to obtain the part pictured, it is called a Spring Cap and it is spot welded to the chassis, called either a Spring Cap or Rear Spring Bumper Unit, the bump stop attaches to it and you can see it neatly inside the rear spring, this can be left or right it has no orientation, I want to buy either new or used. I have tried on some other forums and also many, many wreckers, it is hard to get at so wreckers don't really want to get involved, I was offered one in an 80 series and I could take it out myself for $20.00, Bargain, but they would not allow me to put the wreck on its side to access it and after surveying the job decided I could not do it in the position it was in, is there anyone who wither has one, knows where I can get one or has useful information to help in me finding one, I am happy to pay postage or even drive a bit of distance to remove one from a chassis I can get at? any help appreciated. I am in North Lakes Qld, 35k North of Brisbane. Graeme power

      2016 Aurion Sportivo missing electric blind button

      Hello everyone, Ive just bought a 2016 Aurion Sportivo and was wondering about the electric blind/sunshade button. The car seems to have the hardware for the blind itself (I think but I could be totally wrong) but the button is just missing, with a hole in its place. Does anyone know if it would be as simple as buying a replacement button? I’m not sure what the cabling for the button looks like so I can’t guarantee that the cables are there, though I would assume they are since it seems the actual blind hardware is there? Also, does anyone know what I should do with the other missing button (lane departure switch) hole. Any help would be appreciated
