Rep Power: 300

I am about to buy a used ECU from a member and i need to make sure that it will work. the model # from his is 37820 - plr- u03 and it is from a 03 MT. mine is a 02 MT but i dont see y this one wouldn't work. the 04's where the first year of the extra 02 sensors right?

i need help with this ASAP! i have no car and am in desperate need!

Thanks in advance for any input!

on a side note, does anyone know how in the heck to get that stock ECU out? i tried for over an hour to squeeze that computer out and took half the dash apart and it STILL wont squeez out.
DIY to come if i can get some help.

i am pretty sure 01-03 uses the same ecu, there may be minor updates in the firmware so its better to get a newer or same year as what you have. but it should work, so long as they are both MT. as for getting it out, it should slide out? are there any screws or something holding it? if you still cant get it by tonight ill see how the service book says to replace it when i get home.

that would be great! there is only one screw holding it in and it comes off easily and has plenty of room to the right and left but the bottom of the dash and several wires are located right in front of it preventing it from coming out. if you would, show how the service manual takes it out.
thanks!

well the hoda tech was no help.
he said "um ughh.. it shouulldd work"

Q: is it ok to try and start the car without reflashing the computer? the Tech said i might not need a reflash but i have been told by a few members that i will need to.

if you swap a new ecu, your old key will not start the car. immobilizer will disable ignition/fuel. you can try, but it wont start. you need to have the dealer fix that so the new ecu recognizes the old code from the key.

Rep Power: 300

yeah you gotta be at the dealer when you install so they can reflash it.

well what if i install it and trailer it up there? i aint payen $300+ for what i can do in my own garage. the guy said the reflash was $78

 
Rep Power: 811

yeah thats fine, so long as you have a way to move the car there.
