Hey all! Please move this if this is the incorrect place. I have a 95 bronco 5.0 maf, e4od, auto t case. I have come to find lately that major components such as ecus, are hard to locate. My truck has a tip1 in it and I happened upon a very clean truck with a hug0 ecu in it. 1995 5.0 maf, auto trans, but rwd. My question is will this ecu interchange with my current tip1 (with or without tweecing anything?) and if it does what would I look into changing? Also if it will can I use my current tune with vex1? To be clear I want a spare in case mine ever decides to quit

The TIP1 ECU (SMD-221 hardware) is not suitable for swapping with a HUG0 ECU (SMD-219 hardware) as they use different transmissions. As a general guide you can use any ECU with the same hardware code but you may require a chip or reflashing to have the correct calibration if the one in the replacement ECU differs greatly.

Would YEA1 (smd-221) be a suitable replacement for the TIP1 with Tweecer?

[sailorbob]

The YEA1 should be fine.

Okay so I got a better deal on another one also smd-221 but the strategy is DIX0. Assuming I’m solid ?

[sailorbob]

The DIX0 should be fine too.

Okay so I got my hands on the DIX0 ecu, It may be a dumb question, but can I just disconnect the battery, take the harness off the one in the truck and just dangle the spare ecu to test it? Or should it be 100% installed for any reason. Again, I know it may be a stupid question. Also is there anything I should look out for if the ecu doesn’t operate as hoped? Besides anything stupid obvious like not starting or idling

[sailorbob]

Not fully installing the ECU to test it is fine as long as you are not putting any strain on the wires by having it dangling from the harness.
