Hi all,



My ECU died a few months ago and I was able to source a replacement for the car.

Problem is, the ECU isn’t from a same spec 1997 Tiburon.

I’m not really sure where the ECU came from but the best guess that I have is that it’s from a local Elantra.

I wish I had more details but I wasn’t able to take note of the part numbers when I had it installed.



Anyway, current problem is that I think that the car is now running too rich.

FC became really bad after the ECU install and I noticed that my exhaust has “soot” in it, has a distinct smell and sometimes puts out white smoke.

Upside is that the car feels more torque-y and responsive in the low-mid revs after the ECU replacement (via butt dyno).



Is there a way to fix the “rich” problem without having to get an ECU or a piggyback?

I can’t source a same spec ECU here in the Philippines and importing brand new from Korea costs an arm and a leg.



Thanks in advance!

 

There should be a series of numbers on the outside of the ecu, on the sticker with the barcode.



If you can get us those, it'll tell us where they got the ECU from.
