Fried ECU...

[AznTran517]

I think my ecu is fried since my IACV went bad. I went to the dealer and they wanted $815. I think that's crazy... One of my question is can I go to the junkyard and get a 00-01 Maxima ecu or it has to be and i30? Also do I have to get it installed by the dealer?

Should be fine with any 00-01 max or I30 ecu, except if the year and/or fed/cali spec emissions doesn't match you'll have a few cel's without doing some work.

You don't have to go to them to put the actual ecu in, but you do need to spend (usually $75) for a consult nat's program whenever you swap the ecu on an immobilized car (99+). To save yourself some money you can remove your ecu yourself, leave it plugged in and laying on the passanger floor, swap it in the parking lot and have the program done and finish the install yourself.

How easy is it to remove the ecu?

Why do you think the ecu is bad? Did you change the IAC valve and try a relearn first?

I did change the IACV but my mechanic did a power test and said that its not responding and it's either the ecu or the wiring so I'm suspecting its the ecu.

I would have said the same thing, since it's very very rare for a nissan ecu to take a dump, but it's a known issue on the 5th gens, the iacv fails (probably an internal short) and takes out the ecu. Thing is I don't know if anyone has ever bothered to take there fried iacv 5th gen ecu apart, it could be a very easy fix and once it is out it's very easy to take it apart and give it a quick visual check.

Haven't had the pleasure of taking an ecu out of a 5th gen yet, but on 4g's it depends whether it's auto or stick how I go about it. But don't try to take the ecu out of the bracket, it's an insane nightmare, so much easier to remove the 10mm bracket bolts instead of the ecu to bracket screws. AZfter that you just cut the wire clips, bend the bracket a little, and take the whole bracket & ecu out. Doing it this way on a 4g makes a 2hr job a 2 minute job, seriously.

damn so im sure my ecu is fried too. i have idle problems. (it idles high after driving in stop and go)

Followed your steps and it came out pretty easy but i'm pretty sure installing it myself will be a nightmare! lol... Well actually my uncle owns a junkyard and we have a bunch of imports and I took the ecu out of a 5th gen Auto Max. I dont know if it had traction control or not(parts car missing dash parts). My question is how can I tell if this ecu will work or not?
