Information on EEC Superchips
Recently I had my ECM fail in my 94 F150 and in the process of repairing or replacing the computer. My question is when i pulled out the ECM i found it had a superchip in it and was wondering if there is a way to tell what type of tune it has. I haven't had much luck finding anything online and hope someone on here might know something about it. I also would like to know if it's easy as just plugging it into a new ECM or if it's not that simple. I do have some numbers off of the chip if anyone needs them to answer my question.

I think you would have to contact Superchips to get that info. Otherwise yes you can just unplug and reattach it to the replacement PCM, however many of these things simply added more timing but you can do that without a chip so it may be of little value.

I was wondering if contacting them would have to be done. Thanks for the tips. I do have to agree because these computers aren't anything fancy by any means. Honestly the computer seems like a waste of time in these just because you can't really do anything to change them. Thank God for OBD2 lol. Had a capacitor start leaking on the motherboard of the computer ( i confirmed this yesturday ) and it has been a nightmare to find a computer. Reason i started digging deeper is i had a miss that got worse by the day and the torque converter would randomly disengage causing the whole truck to jerk and sometimes even make the engine fall on itself at a stop in gear. I replaced the TPS not even a year ago and although it fixed the torque converter issue the miss never went away. Today the computer has finally died and in the process of repairing it. The engine would randomly kick itself up to 2k rpms and when you restart it then it runs fine for a couple minutes. Before it was parked it barely could run at all and was gutless. Started it couple hours ago and once again it runs like brand new.

Throw the chip in the garbage can. One of those same ones from Superchips killed a 1997 F250 460 when it wasn't even a 10 year old truck with only 120k. That may have been due to too much timing advance and towing though. It is mostly agreed on this forum that any EECIV chip is a paper weight.
There is really not much need to change the tune on s stock or mildly built 302 or 351.
But, you can actually do quite a bit with the older OBDI EECIV computers with Tweecer and Moates Quarterhorse. Those are what they used back in the day.
I got a refurbished ECU from Pro Rebuild on Ebay.
You can actually just replace the bad capacitors if the rest of it is in good condition. There are 2 or 3 threads on here with info about wihich ones to order. I forget the ratings and values for the specific ones.
Side note, I actually hate OBDII stuff with simple things like gas caps and EVAP etc causing codes. See no need for complicated engine computers etc that need to know what every piece of the vehicle is doing. Just need engine and drivetrain management nothing else.

Source a replacement if you if you have the batch code or engineering number Post your calibration code if you don't.
Put your original in a box or fix/have it fixed.
What engine/trans, etc?

Truck has a 5.8 with the E4OD and 4x4. My avatar is the truck. Have found a new computer I'm getting and fixing the capacitor today. I decided not to mess with it and get a new computer and be done with it. Just a waiting game now so that's the reason for trying to fix the one that is currently in the truck. I have a 76 F150 but it's blown half way apart and an 02 Ranger that needs a tranny but what can you do
