2JZ NA-T TT ecu mod help
 

Alright, looking for some input from the NA-T guys who have done the TT ecu mod while still utilizing the dizzy.

I have the ignitor swapped and the car wired up to mimic the coil packs. Car will not fire on AEM V2 TT ecu but will try and turn over when running Stock GE ECU even with DS62 ignitor. Ive got a known working GTE map on the AEM ecu. I was told something to do with the crank/cam sensitivity needs to be changed in the GTE map to read from the dizzy but not sure. Any input?

I would recommend re-posting this thread in the "SC300/400 > Performance & Maintenance" sub-forum. Plenty of great help there to help you get your NA-T sorted out! :)

And done. Carry on.

i am having a problem with the map sensor i cant get the gte ecu to recognize its there the car runs when its not connected and when connected the car wont start at all any advice. i have a 94 gs300 maybe i have the wires in the wrong position i followed the schematic but not sure what i am doing wrong.. there are 3 pins in the map sensor connector what pin does the ground wire go in? sorry if this makes no sense this is my project car and i dont really get to work on it to often so i have some time and wanna get it done right

do not let the map sensor power wire touch the ground wire or it will fry the driver on the ecu.
make sure the key is out of the car when doing wiring changes, or pull the battery terminal.
