Unhappy Rebuild, or Buy Used ECU for '87 turbo 5spd

I'm looking to buy a replacement ECU for my 1987 turbo 5spd. I don't live in California.

The replacement ECU that fits my car (A-1 CARDONE 72-3187) is out of stock at every store I've checked online. Are there other ECUs from different years that will fit my car?

I keep finding an ECU with a p/n of 72-3192 made by CARDONE that sellers say fit my car, but I don't trust it. According to Rock Auto's website, this p/n doesn't fit my car.

What are my options for ECU replacement? I know the part number, I just need to buy the part. Ebay has a bunch of ECUs for '87 n/a's, but not for the turbo.

A general question: Should I buy a new used ECU, or should I send my broke ECU to get remanufactured? If you choose the latter, do you have any place in mind? I've found one on ebay, but now I can't find it anymore. My dumbass forgot to save the link.

Why do you need to replace your ecu? What are the symptoms? How do you know your ecu is bad?

Have you seen this? https://www.zdriver.com/forums/280zx...l-issue-41021/

thanks for the link.

When we bypass the ECU the fuel pump works. The car cranks, but it doesn't go. I have new alternator, new distributor.

In another thread I found, someone mentions a similar problem, and mentions that the power transistor unit needed to be replaced.

I sent my ecu to a shop to get it worked on, but they couldn't find the replacement part, which is now confusing me based on your link. they shouldn't have had to replace anything, from what I gather.

is there a shop in the u.s. that can do the work on this ecu?

Well what was the part they were trying to source / replace? Assuming they diagnosed it and told you what was wrong???
I do ecu repairs (that's me in that link ^^^ repairing that ecu )... as long as the ecu hasn't been physically damaged (dropped / wrecked etc)

No there isnt a shop to work on them the feds have a law that prohibits tampering or modifications , plus really hard to diag a IC system, the fsm just helps rule out components .
the best bet might be to have yours ECU hooked up to a members car here that matched # s to see if it works
​​​​​​​if it wiped the processor ,your sunk what is the part # ?

WTF? What law is this? Link me to this federal law plz... because this breaking news is going to put every tuner shop in the US out of business.

It is a Environment Protection Agency Law ...the FBI handles federal laws .you will notice those tuner shops close quick a lot of times.
the manufactures training I have been working for gets into it in the FI classes

I have a feeling I will be waiting a long time...

There's no law prohibiting a repair that will bring the ecu back to stock working order (emissions compliant).

There are also plenty of tuner shops that have been around for 20-30 years...

Reading between the lines of the law doesn't mean your interpretation is the actual law.

Ok I'm a bit slow responding , I had the eclipse ,and 9” of rain Mon. night , flooding clean up to contend with .
I am talking of tuning or changing the fuel /emissions window , tweaking the software , turbo charging a non turbo
I have personal experience with this though , I was charged in a Federal case for tampering with Emissions in 97 ,while at a Eagle /Jeep dealer in KC Metro .
I have been a dealership tech since the mid 70's to 07 Nissan /Datsun Volvo , Mitsubishi /Jeep, Toyota 28 yrs wrenching .
The 97 court case – I and another tech ,Andy where named in it . The 95 -97DSM eclipse had at a too rich condition at start up some complained ,it had the rotten egg smell , but some were very weak cold ,there was a update to the PCM ( efi & trans ecu bunddled) there where 4 different software packs to reinstall the software at $270 + each to buy ,the dealer only bought 3 of the 4 as most where covered . I did 40 to 50 of these updates like 4 called for this certain Rom pack that we did not have , the Warrantee clerk was the guy to get these , he showed us that another one would work , it was for Iowa and N only US because they get to -15 degrees and are allowed the extra rich start up only , it runs the same after .
Two months after most were done the Parts manager first said “ hey there is a lawsuit floating around that has yours and Andys name on it” Days later after getting a brief look , we cornerd the service Manager asking what was to be done about this , “we just did what the dealer said to” he says “awe don't worry we are talking to corporate on it .” but the week of the trial 2 days before a assitant for the prosecutor comes by wanting to take photos of us , then says here is what will happen on thursday if you are convicted and from what I see it looks like you will ,from court you will go to a holding tank in town for 2,1/2 weeks then to prison ,either Montana or KS. We freaked out . We never went to court because corporate got together with the factory in Ill. And a senator ,congressman , state dept . And it was dropped , Andy talked of sueing the dealer for he hired a lawyer and was fired later , I got warranteeitus at work and quit 6 months later .
I got hired in 98 at a Mitsubishi dealer in town and then sent to their traning center 8 months later ,where the head guy wanted to meet me ( I thought I was in trouble ) He took a pic and thanked me , the cars coming out of the factory had this extra cold start fuel and was in violation but that was all overlooked with the outcome , it could have cost hundred of millions for Mitsu. , they made a short video with me talking of the story to show/ warn to new techs .

In 04 ? I applied for a techline job at a Olathe Ks. Auto supercharger company , it seemed I was a shoe in with a ASE mastertech certificate , this company made superchargers for 5.7 GM ( I kinda think they stole the pontiac GTO charger, tweaked a bit and knocked it off in asia ) and 302 ferd and universal for big blocks and Hondas .
I was to talk to customers who were installing , servicing their units with solutions , they had a blog and many on it seemed to be Honda street racers , at the end of the talk I raised the point , “Doesn't this change the fuel on emissions” , and got an earfull from the guy “ no we are not changing any fuel settings !” I said yes but the turbo changes how much fuel it uses , I had more to add but the interview was over , I was not about to go thru getting caught up again anyway.
In 2010 ? a TV breaking news segment came on Olathe auto parts company being sued for 10 million dollars over emissions fraud and many people were named …. guess who it was

The FBI investigates this ,as it is Federal . 70% on avr. of there work is non violent crime.
The first gen mitsu Eclipse had a capacitor that would heat up in the FI ECU ,I replaced some ,at a mitsu school a rookie tech brought up the tampering issue about replacing it, the teacher said he would look into it , a few weks later Mitsu. Sent a bullietin to dealers, not to attempt replacing it .

an individual probably not going to be charged ,but blogging about it hurts the chances ,the state cops are the ones to go after an infraction ,not local cops

at my Datsun blog in 2016 the gov. had a law to go into effect banning even off road modifying of fuel systems , many fighting it some exclusions as pro drag , stock car , exhibition .. things change
Have you read Megasquirts about tab. ? States in all caps all products are for off road only
