Hope for GT40 EFI ECU

[t.franscioni]

Ah I just reread the thread and it said any eec with the same HARDWARE should work. So the fact that they both start with L means the hardware is the same between both our eecs? The B on yours and E on mine may be a reflection of the fact that mine has the updated software or "tune" we discussed above in this thread. I'm not sure though if "software " and "tune" are the same thing as it relates to the part number letters "LB" vs "LE"....

Here is a pic of the 2002 GT40 eec part numbers

I believe the hardware is the same, you should be good with the c1a1.

If you do eventually get a read from your computer, can you post the bin file? I think technically that's the one i'm supposed to be running too.

[t.franscioni]

Yes absolutely. Just waiting for the moates hardware to come in.

Would it be safe to assume that the latest tune is backwards compatible ?

[t.franscioni]

It seems likely. I'm new to all this computer circuit board stuff but from what I am gathering (based on advise of guys at eectuning.org) it comes down to the compatability of the tune and the computers hardware and chip clock speed. I'm in process of confirming this with my 2002 tune which is running on my stock PCM eec which has EFI-M39 hardware running the 300M tune and the C1A1 donor hard drive that Van and Rusty confirmed works at least with the old E290 tune. I think an easy way to confirm this is if I sent Rusty my burned chip with the 300M tune on it and he plugs it into his C1A1 donor eec and gives it a try like he did with Vans E290 tune chip. Rusty if your interested I would sell you my chip for cost and if it don't work I'll happily refund you your money and you can ship it back to me? If it works I will just buy another chip for myself and burn another. It will be a while before my engine is back in my boat because I'm in middle of a seadeck project right now and everything is torn apart.

If Rusty confirms this 300M works on the C1A1 donor eec then I'm sure anyone could run it on there GT40 as long as it's TFI ignition and multi port injected. I think some older GT40 had different ignition and throttle body injection systems? Or were those called "Pro Boss" engines and the GT40 was what they called the newer TFI and multi port injected Ford marine engines?

My boat is still covered up but in the only picture I have it looks like it says Pro Boss GT 40 on the cover. I know it's the first year multi port FI. The only difference between yours and mine besides maybe computer tune is the tube intake,and no FCC

[t.franscioni]

Im no EEC expert but I imagine so long as we verify my 300M tune works on the C1A1 that Rusty and Van used as the donor EEC then perhaps this 300M/C1A1will also work on your pro boss GT40. Looks like you also have the TFI ignition and I wouldn't think the lack of FCC would affect this because the EEC only cares about firing the injectors not delivering or regulating the fuel pressure.

Come to think of it. When PCM was selling replacement EECs I don't think you had to defIne what year GT40 or engine tune you had. You just bought it and I'm assuming they would have sold there replacement EECs with the most recent 300M tune loaded onto it so if that's the case then I think we can safely assume the 300M can be ran on any year GT40. Probably still a good idea though to do what these tuning forum guys are suggesting in making sure the clock speed of the C1A1 chip is compatable with this 300M tune. UPS guy just dropped off my moates gear so I will try doing this burn of my 300M tune and post it up here. Anyone that wants to buy a C1A1 and run this chip I'm burning let me know because I'd be happy to sell it at my cost. **** I will just ship it to anyone interested in trying it.... if it works send me $80 if it don't send it back to me.

I have a '96 Super Sport Nautique with the GT40 5.8L with a Bad ECM. I would like to know more from vanhanbr about the F3 chip, and the C1A1 chip.....I would be interested in testing these options with some support. I have a ECM out of the 92 Econo Van that starts and runs the engine for about 1 min then it starts to choke and puke.

"In 94 PCM fuel injected motor was a throttle body Holley with Pro Tech ignition. This motor was rated at 310hp and when running correctly was the most awesome Ford produced by PCM (in production). The bad news is the Pro Tech ignition parts are running scarce and consumers are paying a premium price to get them. The Holley throttle body on this unit is equal to a 900cfm Holley carb and this motor could perform

In 95 PCM introduced the GT 40 as Mid Ohio said same block and heads with a Ford multiport fuel delivery system and Ford electronics. Not the same stuff you find in Ford car, yet Ford product. Injectors are different. Another note is the FCC unit was not introduced until 96 so 95s will not have a fuel control cell."

Thank you ^^^

Is there anything different from a Mustang C1A1 ECU vs a 92 X2A Econo Van ECU? I already have the 92 X2A ECU
