ECU questions

Hi experts,

My KIA forte 2009 was recently diagnosed w burnt ECU

Workshop A recommended 1k+ for a recon, reprogrammed ECU

Workshop B offered 450 for recon ECU (most likely after scrap and plug and play) cause my specific model had a 1-1 exchange policy

My question is will there be any complications for a plug and play ECU or will the ECU relearn and pick up my driving habits and reprogram itself?

Which option would be better?

Do advise me as I'm pretty new to all these

Thanks in advance!

Yes. Just go for the $450, ask for six months warranty.

Once battery disconnected, ECU will reset. How does one fried an ECU? Did you jumpstart the car?

Thanks all

Beats me; but workshop pried open the ECU casing and there's slight burnt marks near the chip on the board. Granted it's a 11.5 year old car and I got it second hand for 1.5 years now so I have no idea about prev maintenance

Just trying to minimise my damage here so if there's any other recommendations or precautions do let me know as well!

must understand.

Kia forte 4 speed had this ECU problem.. after 2011, is strongly recommended.
6 speeds got zero such problem.

the common practice is to change a brand new ECU
but in SG context, unless you still left with plentiful of COE balance.

Reconditioned/ Used ECU- From scrapped car, workshop do some minor repairs or checking before sale.

2nd hand ECU- Freshly taken out from scrapped car.

too bad, otherwise would recommend you go JB and get it repaired or a new one.

1. The gearbox will be stucked at gear 3. For my case, there is shift shock when gearbox is changing gear from 3 to 4 as well.

2. There will be check engine light and code for solenoid valve damaged.

From scrap car market. Some get repaired by components level, but you can hardly find any this type of skill in Singapore. Workshop in China does it.

You have a picture at burned mark area. Get someone has soldering skill and have the component replaced.
