Dear, Im looking for the JAg XK8 4.0L 1997 ECU LJA1410AK, if someone can help. Thanks

 

Before you source a ECU can you elaborate on your engine issue

 

+1 some details. But if it is bad, common for 97 model, you should be able to have it rebuilt. In the US there are a couple of companies, ASI being one that I have used.

Dear Lady penelope, I did it and found ecu burn inside circuit printed with components, so better to replace, Im not sur in this state the ecu can be repaired. So if help in funding for replacement is better. thanks

 

Welcome to the forum AMC,

I have searched the UK specialist suppliers of used Jaguar parts and none of them have LJA1410AK available.

Your only option may be a repair.

Your most likely seeing the solder mask (greenish color) has been eroded away chemically by the leaking electrolytic caps.




What you see in the picture was repaired (I took this picture before sending). I used these/this guy. Very fast turn around. https://www.ebay.com/itm/332427994603
Also, you can see the caps have been replaced before (previous owner) but done incorrectly and incomplete, they just cut the previous cap leads and just soldered the replacements too the old leads - not good for vibration, normal procedure is to clean the through-holes and install. But before installing new caps, clean/repair the traces and re-mask. Then conformal coat and finish up with some electronic grade silicone around the caps for vibration control.
Note: Denso used under rated caps during this era, effected many makes and models. My brother/mechanic found this issue in the 90's (before the intra nets as we know them now) working on a Lexus (even though a German shop, customers bring in their family's fleet), being educated in electronics he realized the cap voltage specs were to low for real world charging systems when people have bad batteries and get "boosted". He say's now these ebay places are cheaper and faster then him.

 

No Picture in your post. If you post it again, I'll insert it in the text of your previous post #6.

Thanks, didn't realize original was like 37M in size!!! Took through a microscope system. I resized.

 

Has it suffered as badly as this one of greenforest's:

or is it more like 1LeSvT?

Perhaps you can post a shot of the damage - replacements for the '97 are difficult to source so you may, as GGG suggests, need to follow the repair route.

 

37mB!

Remember ECUs aren't plug in upgrades, they have to be matched to the car. You just swap them and the car will not start.

 

LJA1410 (without immobilizer) is plug and play.
