Redom ECU
hey whats up guys.. i have a Redom ECU sitting in my garage and was wanting to put it on my car.. im running the stock turbo and .5bar and the ECU has a bunch of japanese writing and says .5 bar so i figure its tuned for .5 bar
anyways my question is, theres a black box on the side of the ECU. It looks like some sort of plug goes on it. Do I need to hook that black box up to a plug anywhere?? or does the harness just plug directly into the ECU and dont worry about the black box? if anyone needs pics ill post em.
Thanks for looking

I could be that since the stock ecu got an upgraded chip by redom.. it must be a plug for redom to retune the upgraded chip. Kinda like evo's get flashes done through usb ports.

Here is another thread from someone with the same question. I found it but did not read through it to see if they knew... you can check it though.

Oops... I read a little bit into it and noticed you had asked about it on that thread too FrankV702. Sorry about that. Anyway, 87 t-66 is right I guess. My JDM ECU came with a little black box. It wasn't the Redom ECU, but it was an N340 I think... I forget. Well, good luck.

I searched for information on google and didn't really find anything. So, I checked Ebay and I'm not quite sure how accurate this is but this is what the item description had said:
THIS IS FOR THE SERIES 5 SECOND GENERATION RX7 FC3S WITH 13B-T MOTOR(89-91).
SPEED LIMITTER HAS BEEN CUT, IGNITION TIMING HAS BEEN REFINED, THE REV LIMITTER HAS BEEN RAISED, BOOST UP, EXHAUST SYSTEM(FRONT PIPE, MUFFLER, DOWNPIPIE), STOCK TURBINE, 1.5 TIMES LARGER INTERCOOLER.
I am not sure if that information was for this specific Redom ECU or all Redom ECU's.
This was one of the pictures for it also...
