Modified Factory ECU 2JZ-GTE

[Makaveli]

So I found a modified factory ECU for my car. I don't know exactly what's been changed or to what state of tune it has been designed for. Would it be safe to simply plug it in? Is there any company or individual in NZ that could read the data to see what's been modified?

Thanks

yes you can plug it in. but i would put it on a dyno so you can see if it is detonating on our NZ fuel and to see what the air/fuel ratios are like. then see if the boost cut has been lifted or removed, see if the rev limiter has been lifted.
There is no way of reading it to see what has been changed.

[BlakeNZ]

then take it to 180km/h plus to see if speed cut has been removed.

[Mr Ree]

Who modified it? Does it have a company sticker on it like 'Mines' et al?

Most of them have just got slightly more agressive timing curves as they run 100RON in japan, plus rev limit raised, speed cut removed, and able to run slightly more boost without going into fuel cut.

If you can identify it, you can sometimes email them to ask what was doen to that specific box

Translation:
Position as the engine is not the pinnacle of Toyota kicked, we started to develop an early stage, have assembled the most extensive amount of data. Sequential system is sequential to remain the best I think also consider practical Considering that the correction enters the IN side of the cam on the wear BIGT / C but there is a problem. The Company T / C main shaft is also applied to the durability of the ceramic blade for thin parts first, however - 400Ps ~ 420Ps main IJ540ccBS1 (less catalyst 2) exchange in the normal 380Ps ~ 400Ps intercooler BS1.2K specification IJ to the main strike UP .5 SETUP the specification OVER450Ps K. We recommend our high-flow turbine of us if you want the MO REPOREW (NML19X11 → 23X15 also extend MAP)! 4D/BIG sedan car does not allow tracking of how other changes such as expansion of the compressor shaft trim size, which is a drawback of the normal mounting bolt, replace the fuel pump and main IJ is required? Note the time of purchase, please buy the adapter in conjunction with TRC CUT speed. IN replacement of the cam side, so can not be taken only up to 248 fast idle. When replacing the injector is installed, please make sure the pressure Regulator. VVT-i engine is under development!

It appears from that to need a new larger fuel pump and larger 540cc injectors for it to work as intended.

I wouldnt run it with your 440cc injectors and 190lph pump as you will be roughly 25% leaner at all points and with less octane...which=far too risky.
