I just pulled out my ECU so I could put in my Pettit one and I noticed that the old one says remanufactured for Mazda. Do all stock ECUs say this or could it have been bought at a later date?

Thanks

 

If I remember correctly, there was some sort of recall/service bulletin that required the replacement of the ECU with a remmaned one. Either way, mine says the same thing.

 

Anyone else notice the same? I just noticed my '94 R2 original ECU says it's remanufactured... and it not only threw an EGR light on a 93, but it put it in limp mode too!

PS: Yes, I search

 

the auto trans ECU's had a recall causing the trans hold light to flash which resulted in a ECU upgrade from mazda which said Remanufactured on them.

 

My 93 R1 also had the "remanufactured for Mazda" on the ECU.

 

i just pulled my friends ecu from his 93 5speed and it said the same thing. i was also wondering wha that ment.

 

Jeff, I have an R2 = manual only.

Oh and I'm sure I'm wrong lol, but I don't recall any recalls (no pun intended) on 94 and 95 FD's. Just the 93s. Interesting this has got any attention until now...

I've heard "ecu recall" thrown around a couple times, but there's no recall of the ECU listed in the standard lists <alldata etc>. But I'm starting to think, was this replaced when they added the black box and updated the fan control system? I believe that recall was pertinent to all 93 and 94 cars, meaning probably only 95s and non-recalled 93-94s have non remanufactured ecus.

Edit: I just noticed there IS a TSB issued for cars made prior to mid 93 to replace the ecu if the car stalls with the 881R series ECUs (881R is always the ending digits for a remanufactured ecu) for that car, and from then on new production cars had a "revised" ecu. I wonder if maybe mazda ordered tens of thousands of the ECUs when they got rolling to get a cheap price and then ended up having to ship them all back to Denso for changes? Hypothetically if that was true, you'd probably only see non-reman ecus in early 93 cars that hadn't ever had that particular problem addressed?

 

Interesting...

 

In thinking about it though, my car is a **** poor example of my theory, as it was #252 in 1993, and well before the permanent change. So if my theory on the TSB is correct someone took my car back for waranty service and complained, maybe we can find some early production 93s that dont have reman ecus? I suppose frequent stalling would have been a big issue though, maybe there's some original owners out there that can at least attest to having ECUs replaced as part of this TSB campaign?

 

Hold up...if there was ANY warranty/recall work performed, it WILL show on a Carfax report. Anyone have their car's Carfax report?

EDIT: I just checked mine. NO service history whatsoever, and def. no evidence of any warranty/recall work being performed. I know it would show it because it showed on my friend's car's Carfax report...

 

I wouldn't even remotely consider carfax the end all of information. I've seen a TON of cars that were in moderate to serious accidents without any mention of it on carfax reports. Its helpful, but its not gospel, I don't EVER buy a car without looking it over real close to see whats been fixed, repainted, etc because its not always 100% accurate. Also I don't think my 7s recall work was on there and its had every recall done, TSB work probably wouldn't show up at all as its not mandatory, its just a suggested fix for possible waranty complaints that may occur frequently.

 

all of the 93 cali ecu's were replaced, at least once, most of em twice

 

BMike, accidents are only reported on Carfax reports if they are reported to insurance. But recalls and service done at dealerships IS reported to Carfax reports. It's something dealerships automatically carry out. But if you take your car to a private shop, that's a diff story. But again, to get a recall performed, you HAVE to go to a Mazda dealership, so again, I think it would show up on your Carfax.

Don't believe the hype, we've tested the theory on cars we KNOW were in insured accidents and had them not come up on carfax before, and I know my car had the fan recall done and it was NOT on the carfax when I bought it. It's a good tool, but I strongly advise using it with care.

 

Yea don't worry, I don't rely on it as being flawless, but I THOUGHT it did report recalls and the such. Oh well.
