hey guys, my auto 1j soarer ecu went bad on me again on the dyno two nights ago... i've been seriously considering switching to a jdm 2jz ecu because i'm tired of buying and repairing the ecu's. i've searched to see what the benifits are to going from 1jz ecu to 2jz ecu but didn't come up with much... all i got is that it is a better ecu with better timming control which cause a single turbo setup to spool faster and it ofcourse don't keep blowing caps like the 1j ecu's. the only downside i found was that the rev limiter is moved from 7k or 7200 to 6500 or 6800 rpms, just alittle shorter. i was just wondering what your inputs would be (other benifits and downfall?), let me know any input is appreciated!


thanks, toua

Switch your 1j alternator to a 2j. This should resolve A LOT of your electrical problems. This might also prevent the blowing of your ECU in the future.

you guys know the difference between the usdm and jdm ecu besides injectors and maf? is the timming map different?... i know the usdm one's rev limit is higher, is there an advantage to running the usdm ecu over the jdm?

has anyone tried the emanage ultimate with a jdm 2jz ecu and successfully raised the rev limit on the ecu?
