Topic: Bad ECM
Posted By: Ski-Naut
Subject: Bad ECM
Date Posted: May-09-2017 at 3:14pm
I have a 1996 Super Sport Nautique with a 351 GT40 Engine. I have a bad ECM, ( Electronic Control Module) does anyone know if it can be repaired? I purchase a new one from NautiqueParts.com that wasn't any good. I had my PCM Dealer talk direct to PCM and they told him that Nautiiquepart.com should have never sold the ECM because they have not found a good ECM yet......I tried a ECM out of a '92' Ford Econo Van and the engine starts and runs for about a minute then starts to choke and puke, so I know the original ECM is the problem. Can anyone help.

Gary beat me to it, the thread on PN seems to be the most promising fix for a bad GT-40 ECM that I've seen.

I'm really surprised that any parts house sold you an ECM, it's known that there are none on shelves and that PCM isn't able to make or support any at this time. You may also be able to find one on Ebay, they are certainly getting scarce.

I have a known good running 300-m on the shelf. Just used it to test another gt engine. I will sell it but I will not give it away.
$900 I will ship it to ya!
Or try E-bay and ski-it-again.com

Not a lot of people know this but Volvo Penta also utilized the GT-40 engine for a number of years.
An example from e-bay yes it is for a 5.0/302 but I have seen ECM's for the 5.8 on E-bay also!

Here is what else I found out - 300m must be the latest software tune for GT 40 the '97's at least used the E 290. It would be interesting to know Nick what the numbers were on your original ECM . Can you check and maybe post a picture?

Fill me in since I'm curious and the above is confusing. Who hasn't found a good ECM yet? Nautiqueparts or PCM and why shouldn't Nautiqueparts sell them? They sell other PCM parts! Also, what happens if the ECM fails and you take it to a authorized PCM dealer for service?

I don't know where NautiqueParts.com purchase there Parts, I'm assuming that they would get the ECM from PCM. PCM told the dealer that I took my boat to that they can't flash or repair bad ECM's. PCM said that NautiqueParts.com should have never had one on the shelf to sell because PCM hasn't seen a good ECM that could be repaired. I am starting to find some people on PN.com that are able to read the ECM and could have a solution for anyone with a bad ECM.......but still testing.

So, what you are saying is Nautiqueparts keeps bad parts on their shelf?

Pete I guess due to the age PCM is just not supporting parts for the Ford engine. Just try to find the thermostat housing for example,not a problem with freshwater boats they last forever but a saltwater boat they rot out fast. So when it comes to the ECM,PCM didn't make them Ford did. I question who even did the programming of them,l'd bet Ford did that too. It's been something like 17 years since Ford got out of the marine business and have moved on to different engine families they are not going to supply parts forever. I don't remember if I told you about my Dads '00 Lincoln Town Car when the dash went completely out. It was like 11 years old with 70k on it. Dealer said no way to fix no parts. Luckily I found a place on the Internet for around 300 dollars that repaired the original dash and had it back in my hands in under a week. They made a lot of Town Cars so someone saw a market,who will step up when in a few years these new Linc systems start failing and their not supported any more - not quite as many of them being made.

Gary,
I completely understand that part support doesn't last forever but back to my other question, what happens if you take the boat in to a dealer? They just wave goodbye to you? Is this why the PN member went out on his own to find a solution? I'm heading over to Watercraft Sales later this week to see Ryan regarding the mini and I'm going to run it past him and his service writer. I'll report back.

Pete, the point is that as far as anyone knows there are no longer any parts dealers that have ecm's for GT40 on the shelf. A used ECM out of a working motor will work fine, but once they are bad there has been no rebuilding technique. The guys on PN are coming up with an interesting fix at low cost that if it works will really be good insurance for guys like me that plan to keep their boat.

I'm not sure why you are questioning the OP on Nautique Parts, obviously if they sold him an ECM and it doesn't work, then they sold a part that doesn't work. Seems fairly simple to me. I would hope they would take it back, don't know if that has been asked or not.

I know the local dealer here, a friend of mine, will not have a solution for a bad ECM in a GT-40. So yes, he will just send you away, because he literally has no way to solve it.

Maybe I missed it but I don't believe the OP ever stated or confirmed the ECM was bad? Again, I'm just curious what happens when the ECM's go bad. Yes, it will be interesting and great if the PN member finds a solution.

That is exactly what the Lincoln dealer did Pete and dad had bought quite a few cars from him. I would venture to guess that a boat dealer would suggest a re power though. I don't know if anyone has ever tried but if it were me I would get ahold of one of the ecm rebuilders on eBay and at least ask if they could repair one,I don't know what's involved but on the Lincoln dash it was a known problem that often had happened to the failed ones. I'm fighting a problem on my Jeep right now,the check engine light comes on with no codes. I did some checking and hose replacement since it has to pass emission testing. After failing test I took it to the dealer,he says it might be the computer it's the only thing left in the system. My fix was to take it in to get tested when the light was off and it passed. Few days later it's back on with no codes found again

Gary, I had a problem getting my cel to stay off on a 2003 Durango. It kept coming up with evap codes, endless finding and changing out the hoses. Then it just stayed on, I'd reset it, a day or two later back on again. My repair shop said they can pass a vehicle if no codes are found, they did something to make special note of it and gave me the inspection info sheet to keep in the car. Not sure if IL has similar rules or not.

I did call and talk to NautiqueParts.com and they would not refund my $600.00 for the ECM because they don't take back electronic parts. I never hurt what was already broken....I proved that when I got the boat to start with another ECM.

PCM offers a kit to solve your issue, George at Christine marine has the parts you need to get your boat up and running for the summer. part number IG8525N   has in stock. This is Woody that was at Southeast Correct for 35 years. THis kit comes with everything that you will need to make the motor better that ever.

If it was only that simple. Since the Gt40 is multi port efi that won't work, that is the replacement for the pro tec system. You still need the "brains" to control injector timing and advance and things like limp mode etc.

It is still pretty much the next step here outside of getting handy with a soldering iron or the solutions being worked on over at PN. If I was a PCM garage or shop and it wasn't being supported anymore I would send it back to a carb and distributor in a hurry.

You are probably getting pretty close to justifying an excal bobtail but in another 20 years you will need a new ecm for that one...

Dave I'll bet we have similar problems p0456- (ECM) has detected a very small leak in the evaporative system ? was the old code before I took it to the dealer,now just a light and no code. Here in Illinois if you spend over $450 you can get a wavier. Our son went to get one but I think he took an attitude in with him and found out that does not work. The test center looked at the dealer work order and noticed it had Grand Cherokee on it when in fact it's a Cherokee. Even though the vin was on the sheet too, the guy gave him a hard time. I took a chance and told just to him to take in in when the light was out.

Hi in the car industry there is a company called Cardone.    They can rebuild ECM modules for cars. It should not be to hard to send them a ECM to save the program from then they would have the program to download into a ECM after it has been repaired. If I get a chance I will investigate further. This should not be that hard of a problem to solve.

Well I think your partially correct Pete in that it's proprietary but if according to the PN guy they were able to read and record the programing. It does not seem that they can reprogram an ECM but they can add a chip to override whats in there. Here is a link to the http://www.moates.net/f3-ford-memory-adapter-p-101.html" rel="nofollow - "chip"

Hi just in case you did not see the other post. I talked to a Cardone representative today and they do not have this part number on file. But to get a broken one repaired. Take the ECM to a local Cardone dealer. They will send it to Cardone and once it gets to the Philadelphia repair center it should be a five day turn around. Once it is evaluated and repaired they will assign a Cardone part number to it and then anyone should be able to get one. I have used their repair service before with no problems. Hope this gets rid of some of the fears of owning a GT40 engine.

A quick Google search tells me that you're the guy selling these, so why not be upfront about it in the first place?

Mike's intentions confuse me. At a price of $650, vs the $113 on the PN page, what is the difference between the two methods, other than $537 more

Maybe just time? If I had a GT40, I'd probably pick up a spare or two via the linked page and be set for a long time.

IIRC, Mike came to the site asking for help, and he got it...Now he's trying to help (while making a big profit)

Scott,
Are you willing to take a chance at buying a used ECM off Ebay and then replacing the chip in hopes it would work?

Scott I'm sure that he must re manufacture and rigorously test each donor ECM. Then he had to buy the the reader and burn equipment and have an original good ECM to download the original tune- so it all adds up. You and I would just go on ebay buy a ecm and hope it works. Then we'd go on the original PN thread and have one of the guys who did the original figuring this out, burn a chip with the tune they pulled from their very own ECM. Then you'd try to get them to take compensation for all their help which they would refuse because they were happy to help out the community. Either way it's cheaper than PCM's fix of replacing the complete engine. So you do your homework and make your choice. Up and running I have around 180 in mine.

Curious Pete how often do you run across a bad automotive ECM? I gambled 75 bucks on one, it's fine. How much money will be spent on lottery tickets this week with the odds being much greater?

I agree, get the ECU from Mike. He's giving a 30 day warranty! What could be easier? These GT 40's are great engines, keep it going.

Gary,
You are correct. Even though I did buy a Mega ticket last week, the chances are higher with getting a good ECM off Ebay!

I found the fix for my PCM GT40 EFI late this summer. I went through the whole process of buying a used ECM off of Ebay and adding my tune to the Motes chip and didn't work for me. I know a couple of people that it worked for. Contact Norm at Affordable Fuel Injection just north of Detroit MI and he will get you up and running. Here is the web site   https://www.affordable-fuel-injection.com/

You should read thru Mike's old posts here on CCF to get an idea how he does things

It's pretty easy to find his Ebay listings too

With multiple Ebay accounts if you look halfway closely

When i had a problem with my 95' at the start of last summer, there was no one online selling ecm's for the gt40. I had to do my homework, buy different ecm's off ebay and buy the programming equipment to get it up and running. If there was someone online that was just selling the ecm, i would have went that route to get my boat in the water faster. Im simply just trying to provide a service to make it easier on people that dont want to do the leg work. The ecu's on ebay that you have to use are starting to get into the 70-100 dollar range. The prices are going up. the chip you need for this also runs 85 dollars and that's not including the programmer and the adapter.

Each ecu i send out gets plugged into my gt40 to make sure everything took and it works like it should.

I've been using the 300m tune and its been running good in my 95'

Maybe the guys on PN can use your "help" since you got a lot of help from them

I don't see any additions by you to the ECU thread over there, offering your services Edit I do see you selling your ECU's there though.

I guess your research doesn't seem to lead you to believe that some Moomba boats had a GT-40 option since you left that off your ever expanding website.

The same research must have overlooked OMC too

How's the research going?

There's more out there for you to find

I'd give you a clue or 2 but I don't feel like it.

sorry for the delayed response keno, busy doing research.   i guess i'll just have to sit back and cross my fingers for more clues.
Thanks for the merchant info, I've reached out and Im curious what it will take.

Maybe we should have some fun and do this kinda like Wheel of Fortune

I'll be like Vanna White and fill in the letters as they're guessed

Here's a start
                                    R
----    ----     ----     ----     ----    ----    ----     ----    ----

Another hint, it's not Starcraft

Edit    Another hint, the answer is in your other thread but spelled wrong

Speaking of Vanna, I look nothing like her

And none of those letters she's pointing at are in the boat's name either

Date Posted: October-28-2018 at 11:34pm
And I thought you were spelling Chevrolet but put the R in the wrong place.

We haven't met yet, but somehow I knew you didn't look like Vanna .........
