Careless Posted January 7, 2007 Share Posted January 7, 2007 so I have a problem with one of the engine computers that i have here. one works fine. it's a newer style one that was bought by the PO. upon opening it up, I find that the newer style one uses different IC's (integrated circuits) than the one that came originally with the car. The components im looking to replace are parts of the uniterrupted power supply (this is what my dad says, i trust him, he's been teaching microelectronics for over 30 years)... problem is, I can't locate these part numbers. If you look inside the earlier ECU's, the parts that are damaged are the small round things with the finned heatsink. they look like a black sun or star. the parts are HA1808P HA1809P HA1902P (or 1802P... not sure, my dads writing is bunk) on the later style, they have different circuits and the board design differs in that area. Does anyone know of any part numbers that I can use to replace these ones here? please don't withold secrets if you're an ECU repair-man. I'll get it done, it will just take me longer anyways. I'm doing this for me, and no one else. thanks, Raffaele Quote Link to comment Share on other sites More sharing options...
datsunlover Posted January 7, 2007 Share Posted January 7, 2007 Hey man, I doubt I'll ever use it again, so if you want it, you can have my old ecu (75 280z) for parts or x-referencing or whatever. If it'd be of any help.. Quote Link to comment Share on other sites More sharing options...
Careless Posted January 8, 2007 Author Share Posted January 8, 2007 well if i did take your ecu, all i'd be doing with it is nothing, so i'd rather you kept it for someone else who is more in need than I. Thanks for the offer. I'm trying to repair this ECU for that same reason, so if anyone ever needs one, I can give them a working ECU. know what I mean ? the IC's shouldnt cost more than like 5 bux each.

Nismo280zEd Posted January 14, 2007 Share Posted January 14, 2007 I seriously doubt you are going to be able to find new electronics from almost 30 years ago. Electronics and ECU's have changed drastically in the last 10 let alone the last 30 years. More than likely it is going to have to replaced with a compenent that does the same thing but is much newer and much smaller and probobaly looks nothing like the previous. Atleast that has been my experience with them. Best of luck. Quote Link to comment Share on other sites More sharing options...
