I'm creeping up on 30k and would like to know more about these TSB's. Where can I get more info?

 

yeah me as well since i got my car in 2001 i must have to goto the dealer for all these problems

I'm pretty sure almost all of the ones you listed, if not all of them, are available in Adobe PDF files courtesy of org member studman.

I looked them up at Nissan's techinfo site. Looks like some are for part changes when a component is replaced. I would like to know who has had the following done and what they did:

03-060 JUN 03 Engine - Cold Start Rattling Noise
02-056 MAY 02 Suspension (Rear) - Bottoms Out on Bumps

People have said that the rattling will not harm anything. If #2 involves adding stiffer springs, I would be curious as to the ride when the car is empty (since the TSB revolves around a full car or 4 to 5 passengers).

 

I went in this morning to have my tires rotated, while there I asked them to check out my ECM and see if my car required this. He told me technically I needed to be showing the problem (which I wasn't) but they would check anyway. Turns out I needed the computer upgrade and the new MAF.

I didn't really notice a difference, but wanted to get this done incase it occurred outside of warranty. Can anyone (DaveB) comment on this TSB?

What is the difference in MAF (larger, less likely to foul from oil/dirt, etc).

What does the ECM program upgrade change (transmission characteristics, engine rpm, etc)?

 

Anyone?

Interesting, I would have thought someone on the board had this done (seeing as how everyone is obsessed with performance) or knew what it did.

 

Have you already had it done, or not, because you said you could not tell a difference? I have a 2002 auto and had the ECM reprogramed and got the new MAF,and BOY CAN I TELL A DIFFERENCE in the way this engine runs. Most people have a hard time getting a dealer to do this TSB. The first dealer I asked would not, but the 2nd one I called did, no questions asked.

 

There are many threads about the MAF/ECU thread, but the search feature is down for non-donating members.

Basically, the update helps prevent the meter from going bad, but the new meter can still be blown.

As far as the performance difference, it depends. If your car is not hesitating, etc, then you'll probably not notice a difference. But if it is, then you may not a difference.

If you want to know more without reading through pages upon pages of threads, spend $20 to help support maxima.org and become a donating member. Once you are a donating member, you can access the search feature, which will give you a list of the threads regarding this issue. Plus, you help keep the site up and running, as well as help for future developments and upgrades.

 

Yes, I did get it done. I was not experiencing the hesitation, but wanted to get the parts changed out if (and they were) part of the TSB. The dealer did this no questions asked.

I was just wondering what changes were made with the ECU upgrade and how is the MAF different than the existing one?

 

But what else does it do and what is different about the new MAF? I assume the ECU upgrade takes care of new/different variables coming from the new MAF...but what else?

Does it change any of the engine characteristics? Does it change anything with the drive-by-wire?
Does the new MAF resist oil build up better?

 

The new MAF's design is the same as the old one. The only changes made to the sensor was the housing that surrounds the hot metal film on the sensor itself. We do not know why they (Hitachi/JECS/Nissan) did this.

This is unknown. All we know is that the ECU could have blown the MAF due to passing a voltage (or ground) outside of the normal operating characteristics of the MAF. This has yet to be proven or dis-proven.

No.

No.

Yes and no. The sensor's housing (not the tube) is what protects the film itself from oil and dirt. They did change the housing (not the tube) between the sensors. However, it is not impossible (or unlikely) for dirt or oil to get into the sensor housing and onto the film.
