life of capacitor before failure in 1jz ecu?

[BurntBisquit763]

I am doin a swap soon and I've been reading that the capacitors in the 1jz ecu's were bad, my question is, people who have done the swap or has a 1jzgte, when did you capacitors go? How long was it before they went? I mean a standalone would be nice but I'm just buying what need to get the car running.

Replace them regardless and clean the board if there is fluid from a leaking capacitor.

Mine havnt gone yet.

There is no set time on when they wil go. Some sooner than others and you'll be lucky if they don't.

alright thanks fellas

They're electrolitic capacitors. They dry out and fail with age.

Anyone that's into electornics hates them, but they're a necessary evil because of thei high capacity for their size.

They last about 15 to 20 years from the build date of the car they came from before they start to go bad.

If you can, run the car off the 2JZ ECU or get a standalone.

whats wrong with the 1jz ecu besides the capacitor? 2jz is more reliable?

Capacitors and if they leak bad enough, it can mess up the board.

2JZ ECU are super reliable, like the 7M ones.

interesting, it would make sense to just save up and wait for a standalone though, i want to run a standalone in the future anyways, have you guys have experience with the driftmotion service on the 1jz ecu capacitors? It looks like a deal

actually, 2J ECUs have the same issue depending on age.. this is from quite a bit of experience at this point.

the first thing you should do after acquiring a 1J/2J ecu is have all the caps replaced. by waiting, you are just prolonging the inevitable.

Really!? I have never seen a stock 2JZ computer go bad. That's surprising to hear.

Standalone is always best if you have the funds.

3P, great link!

How is the 7M stuff coming along? I posted in your thread but got no response.

 

[thesupragod]

Their AEM V2 plug and play also looks like a deal, go with that!

Some new developments will be posted in a few days...
