I'm trying to determine which ecu I have. I purchased the ecu really cheap, but the numbers were not on the exterior of the ecu housing. On the inside, the one chip has 079753-1054 and the board has 079721-2284. Can someone tell me if this is an N370 or N374, or what ecu it is? It was supposedly an N370 per the seller. Any help would be greatly appreciated. I have searched the forum with none of these numbers found in the other threads. Thanks,

 

if it plugs into ur s5 and doesn't have a little tab on the side or a little black box it should be a n370 unless someone went thru great lengths to disguise a n374

 

The tab on the side can easily be removed.."great lengths" not required.

Open it up and with the connector on the left and the board swung out to the right, look in the upper left corner of the bottom board, see if T808 is populated or not. It's a stand up transistor just to the right of the large T800

 

Here are some photos of the interior of the ecu in question and a shot of the (T808) capacitor. Thanks in advance.

 

N370

 

Thank you,
