i did a t2 swap in a 87 gxl na hit a wall at 3800.
tested secondary wires at ecu
got pin out used gound in ecu and tested secondaries at ecu
front secondary - 12v drop to 8ishv when at 3800
rear secondary - 12v drop to 8ish for split second then back to 12v when hit the wall
stays at 12v car continues past 4k but is horrible
is this due to the n340 ecu (its the one that came with the jdm motor)
or bad injector
or bad ground (there are about 4/5 4 gauge wires from motor to chassis)
if it might be ecu which one do i need?

 

just switched to my na ecu and the wall i was hitting is GONE WAHOOOOOO
im using the N326 ecu (my old na ecu)

WHAT ECU DO I NEED
i dont want a speed limiter what would be best to go with

 

Sounds to me like the ECU itself was bad. By the way, no USDM ECU's had a speed limiter, not sure about JDM's though.

 

yeah it was actually you and hailers and nzconvertable on some dudes thread from like a year ago that helpd me out lol thanks

what is the stock us t2 ecu number like an N333 or an N332

According to that its N332, though I think the 2 are interchangeable.
