FOR SALE (3) 14CUX / GEMS EFI ECU / ECM Units

FOR SALE – (3) 14CUX / GEMS EFI ECU / ECM Units

These were part of my pre-overseas part stash while I was accumulating and hoarding parts for my two NAS trucks now unfortunately gone. I found these wrapped up in one of my toolboxes a few days ago, and I guess I missed them back when I sold off stuff in 2013. All of the Ds I'm now messing with are diesels or carb-ed V8s.

All three ECM/ECUs are part numbers associated with early 90’s RRCs, but will work in 3.9L GEMS/14CUX EFI Defender V8s, either by swapping their internal PROMs or in their entirety. Doing so is reputed to increase the rev limit and improve performance of the 94-95 NAS D90s, although I didn’t notice a big difference. My 94 did, however, already run great and I normally drive my Ds like an old man.

- AMR3728 w/functioning original ’94 D90 PROM installed in it (This was the one I swapped PROMS with) Outer case shows some corrosion, but the connector, case inside and internal PC boards, etc. are in perfect condition. - $75 shipped in CONUS **SOLD**

- AMR3728 w/stock PROM for RRC - $115 shipped in CONUS

- AMR1423 w/stock PROM for RRC - $115 shipped in CONUS

- I also have a 14CUX PROM in an anti-static package, but I don't remember what it was from. It's either another RRC one or a stock D90 3.9L one. Perhaps one of you knows and can use it? - $25 shipped in CONUS

Payment via Paypal "gift"/payment to friends or you pay the additional fees.

Thanks,
Murph

What is the difference in the AMR number? I need one for a 95 RRC SWB.

Thanks, Lav. I'll get right back with you.

Matt- I'm not completely sure myself, but based on my research they're supposed to be interchangeable and I was told that part numbers were a function of when and where they were made. Searches by part number mention their installation in both 3.9L and 4.2L 14CUX RRCs, depending on website.

Thanks for your interest, guys.

Can someone can tell me if any of these will work on a 95 RRC 3.9. I assume one made in '94 would be the same as one in '95?

Chris-

Wondering if the two you still have available are compatible with a 1993 NAS 110?

Thanks!

Hi, Tyler-

That is what all my research online years ago said. They're supposed to work for any of the 14CUX EFI 3.9/4.2 (non-GEMS 4.0/4.6) V8s. I did it successfully twice with two other ECUs, only I chose to just swap the PROMs and not the entire units as my stock ones were fine, so my confirmation was just that.

I was told it would improve fueling slightly and change the programmed D90 rev limit, but I could never tell the difference by seat-of-the-pants.

The case mounting brackets are slightly different than those in the D90, and I didn't want to get into removing and replacing those, too. I'm not sure how the bracket is set up in the D110, so you may need to swap that as I saw.

If you have the stock 93 14CUX 3.9 V8, I can't see why they wouldn't work.

If I put this in 1994 D90, will this get rid of the speed limiter at 90 mph, and take it to 120mph? Just plug and play?
