Hi all,

I just bought a 1999 e350 7.3 diesel with a '2003' 7.3 diesel in it (seller has yet to provide paperwork ...) for a good price (maybe).

It runs well but failed smog cos the 'Service Engine Soon' light was on, and could not be re-set by the tech. The previous owner thinks the ecu is the problem.

I checked the ecu and its (still) a 1997-99 unit and I see that 2003 ecus are different part no.s but without a VIN for the '2003' engine I can't order the right ecu.

I have 2 questions:

1. Is it possible to look up a Ford VIN from an engine no. (74JU2U849243). My local Ford dealer could not.

2. If all I can do is narrow it down to a 2003 engine, how do I go about getting an ecu, and re-flash to what settings?

Thanks guys

 

No ..International makes the engine.......You might be able to find out from International but I doubt it .....Ask another Ford Dealer OR find a 2003 Van with a PSD and use that VIN....

 

The PCM codes are here .......http://www.thedieselstop.com/faq/949.../pcmcodes.php3.You will need a PCM in the same "Family " as your engine The " family" Numbers are the ones in the column that says MODEL-TYPE...then it will work...For re-flashing you can contact Jody at http://www.dp-tuner.com/ ...........he can do it ....On Edit, it looks like the Model Type you want is DPC-455....

 

Wow, thanks for the quick reply. so CAL R/C means California?

I tracked a DPC-455 down - 03 2003 Ford E350 Electronic Control Unit - Fuel Injection - A1 Cardone - PartsGeek - is this what I need?

When I look up DPC-455 I found a chart showing 5 Control Unit part no.s for the 2003 ( Ford firmware update database ) - how does that play into how I get it flashed?

 

OK,

Any idea if the ecu in at the moment is also a dpc-455:

F7TF-12B599-AB, 8J30-3, 7FAA0

 

Yes ...After 1997 All vans went to the AB Injector which is Cali ( read Split Shot ) Since Vans DO NOT have Intercoolers they remained the same .........In my opinion, You do not need to get it flashed....Just put it in..... unless you have stage 1 Injectors ( Single Shot ) ....You should have Split Shot Injectors...Unless you are putting Stage 1 Single Shot ones OR Hybrids in you do not need further Tuning unless it shifts Funny...Email Jody and see what he says...

 

You need the 4 letter Code and cross reference that with the chart I posted before........

 

IMO you need to go back to the seller and have him figure it out and legitimately smog it, as he is required to do under state law.

Good price my **** if you can't register it and it becomes a pita every two years you own it.

I'm sure it can be figured out, but it's his job to do so.

 

Yep, good points and I'm bearing it in mind if I can't sort things out over the next few days.
