New ECU or second hand unit ?
Hi Folks,
it looks like I have a faulty Engine computer in my Rx330. It is throwing a lot of codes and Ive had a couple of opinions that the ECU is the problem. I was hoping that some of you knowledgeable people could give me your opinions on the pros and cons of fixing vs getting a second hand computer. It seems that a second hand one is a lot cheaper but there is the complication with the keys etc, is this easily dealt with at home ? Has anyone here had success with a second hand one ?
Thanks in advance.
Matt

I haven't experienced the issue although I would replace the ECU with a used one considering the age of the vehicle if that was the case.
Some are as low as $100. on Ebay. The DIY doesn't seem too complicated....

If you problem was a constant one, I would say get yours repaired. But having an intermittent problem makes repair a less-than-guaranteed repair. If it happens to be working ok that day, the problem may not be repaired. The repair services here do return ECUs with a "problem not found" note.
Getting a used ECU would be ok as long as it works ok. If you go for a used ECU, see if you can get a guarantee that it works correctly.
There may be one sort of "problem" with replacing the ECU whether new or used. The ignition key recognition may be stored in the ECU. It is on some cars, but I don't know if this is true on the 2nd gen RX. Maybe someone else can chime in on this.

Thanks for the responses. I'm definitely leaning towards a second hand one. The units with my particular numbers seem to be a bit thin on ebay but I found one for about $300.
I found this
video to reprogram the keys. If anyone has tried this or knows of any additional issues with fitting a different computer I'd appreciate advice.
