Whats the difference between a JDM and a stock 3sge?
No EGR I think is the major difference.
no egr, different exhaust mani iirc, and different ecu (fuel maps and timing i think)
According to Wikipedia:
JDM could run a little more agressive because they didn't have all the polution control stuff that the North American version needed to pass inspection in all the States. More importantly the fuel over there is higher octane allowing for higher compression and more advanced timming.
only difference in the exhaust mani is the hole for the EGR pipe
^^ and they didnt have teh 4 wire 02 sensor take over i dont think
sounds like i got a JDM, SWEET!
uhhh no. take pictures of the throttle body and on the right side of the vcs and right side of exhaust mani then maybe
I need a JDM ECU for my race car. The fule Maping is the main differnce.
i might have one. i'll have to look.
I do believe its sitting ontop of the motor next to the intake.
BTW I had to pirate a hose clamp off your motor.
not that one.
So..is a jdm ecu plug n play..?
What kind of dif does it make?
Probably better fuel/timing curves.
So better throttle response/mpg?
I would like one if I could find one to go with my jdm 3sge.
IMO, you REALLY need to get one if possible.
I've got a JDM gen 1 ECU, my car ran like shit with it and made 116hp vs 123hp on the ADM spec ECU. We're going to try playing with timing and run better fuel for the next run as we only did a straight back-to-back comparison, but don't believe the hype.
