Hope for GT40 EFI ECU

[t.franscioni]

DW beat you to the punch but no worries if we conform
it works and you want the updated tune I'd be happy to load it onto your F3 you got from Van. Those F3 chips are eraseable
and can rewrite them. I got word from the tunning forum guys that my read I took was no good. Contacted Moates about it and we all think I need to power my EEC with a 12v supply while taking the reading, not enough power from the USB laptop port to fully power the EEC to get a accurate read. So I'm going to work on that and get another read and have the tunning forum guys look at it and give the thumbs up before I send anything to DW for testing.

awesome! yea.. i'll wait to you get it where you're comfortable and then send you mine. Thanks MAn!

Van do you still have the C1A1 ecm out of the 2.3 liter Ford Mustangs that you posted about 3 weeks ago?

[Fgroce]

I looked into the cost, to repair an ecm, it looks like it will be between 100-140. Not too bad.

[t.franscioni]

Well at $100-140 for repair that's certainly cheaper than what I paid for all this burning and chip writing equipment... I think I'm in it $220 for this hardware and chip add another $25-$50 for a donor EEC....

[DW SD]

Tom,
I'll gladly chip in to offset some of the cost of your hardware. Guessing others will, too.

I'd like to have a spare ECM rather than sending one off and awaiting return from repair.

Appreciate that but really I'm not looking for any shared costs of this burning hardware I get to keep the moates gear so I should be the one paying for it. I was just pointing out the costs of Vanhandrs solution to the EEC problem as compared to what Fgrose is looking into.

Seems like I've read a dozen threads about the lack of support for GT-40 ECM's, and all of a sudden I'm seeing there's a place that repairs them for short money. Are we sure this repair works? Not meaning to question that company, just surprised nobody mentioned it before.

[Ski Naut]

I'm confused, I just got off the phone with Cardone Tech support and I was told that they have no way to test the ECM out of a Boat. I told them that it was a Ford GT40 351 Closed loop system. Still they are not sure that it could be done. I'm guessing they have never tried. Any input?

[t.franscioni]

I'm have not looked into cardone but I do know from the tuning forum that they did say not to throw away your broken EEC because parts can be taken from other EECs and soldered in to replace broken components. The issue I see for the do it yourselfer is how do you figure out what components on the circuit board are busted? Soldering in and out new resistors, diodes, chips, etc isn't difficult but figuring out which ones need to be done requires knowledge of circuit board components. My understanding is that it is likely these EECs could be repaired in the rights hands. I read somewhere on here or correctcraftfan that PCM was accepting broken EECs and then sending them out for inspection and possible repair to an outside company. If that's the case then a great solution would be this chipped donor EEC to keep you going while your original EEC was getting inspected to see if repair was possible. PCM though would be who I send mine to before Cardone as of now.

[Ski Naut]

T.franscioni, you have the moates system, would you be interested in programing an F3 chip if I purcahese and send to you? I purchased a doner C1A1 ECM today. If you are willing give me a cost and I will send it to you.

Thanks

Right now I can load Vans E290 tune out of his 97 GT40 onto a chip for you because him and Rusty confirmed his tune file works. I am working on getting my tune file out of my 2002 GT40 which we all believe to be the most recent "updated" tune PCM made for the GT40 motor. What are the differences? I don't know.... I just know somewhere between 1997 and 2002 PCM updated the tune for the GT40 motor. Sure I'd be happy to burn a chip for you and mail it to you if you send me the chip. Just reimburse me the shipping costs to send the chip from me to you. I'm hoping to have time tomorrow to try and extract my 02 GT40 tune and let the tunning forum guys confirm it's a good read. We still don't know for sure whether my 02 tune is compatible with the C1A1 we shall see but we know the 97 GT40 tune is. You can wait it out or I can load you the 97 tune.

If you sent cardone your broken ecm and a c1a1, they should be able to remove the main chip and resolder it in the c1a1. As long as main chip is still working, that world be easy way to fix ecm. Eventually, all the main chips could break, that's why its important to have a backup file just in case. Getting ecm fixed is great, but its nice to have a plan b with moates. As far as money, I think old marine ecm were selling for $500-$1000 when available at the time. If you want to keep boat going, I would stockpile a few c1a1s.

[Fgroce]

The tech support at Cardone that I talked to said they would not be able to give specifics until they trouble shot the bad ecm. I understand what is required to repair and test a ECM and I do not think it will be a problem. The worst that could happen is you send them a unit and they send it back not repaired. Once they have the two different programs they could load the latest version in yours if you wanted. I do not think these marine ecm's are that different from car units. Once they find out they will probably be able to burn the program to the other units that like it other than program. Ford was looking at it from a money stand point, selling low volume engines that they no longer used in production trucks, so any production change greatly added to the cost per unit. using currently available parts to sell to the marine industry kept the cost down. Time will tell, I do not need one repaired, but if I do I will send it in, and give them a shot.

Vanhandr when you opened your C1A1 was the hardware and layout the same as our PCM units?
