WoodsWagon Posted February 4, 2006 Share Posted February 4, 2006 I took the cover off of the 92 legacy ECU this morning and noticed that there is a taped over base for an older memory chip to plug in. I'm wondering if it is a spot to put in a prom chip for some purpose by subaru? Has anyone noticed this before? Is it a spot for a chip for the turbo model? I'm curious.

tunered Posted February 5, 2006 Share Posted February 5, 2006 isnt that the place where you put the hp chip? the one that gives you 450 hp with465 foot lbs of torque,at 42 mpg? Quote Link to comment Share on other sites More sharing options...

Do you happen to have an extra one of those chips lying around? Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted February 6, 2006 Share Posted February 6, 2006 It's more then likely a subaru specific thing....does it look anything like the 90 ECU? http://www.surrealmirage.com/subaru/images/swap/19 Vikash (VRG3) on the legacycentral bbs would probably know more about it.

WoodsWagon Posted February 6, 2006 Author Share Posted February 6, 2006 Actually, it looks nothing like the 90 ECU. It's a single main board job, with a heatsink with 3 power transistors and a couple of IC's running parallel and sticking up on the same side of the board as the yellow connector bus. keeping the yellow connector at the bottom, the main set of IC's are in the upper left quarter. the 28pin landing port for a chip is in the far upper left of the board, again with the connector facing down. kind of remarkable the difference in construction between the years. the sticker on the ECU says: Q7 22611 AA932F JAI8000 RL8 2514 if that helps. Having the 400 whp chip would help, seeing as i'm planning on shoving some boost down the throat of this poor motor. Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted February 7, 2006 Share Posted February 7, 2006 It's probably the JECS ECU. I'd suggest seeing what VRG3 thinks. Quote Link to comment Share on other sites More sharing options...
WoodsWagon Posted February 7, 2006 Author Share Posted February 7, 2006 you want to ask him for me? I'm not a member of legacy central, so I can't contact him. The board says JECS on it and it has a Jecs/Motorola chip right next to the 28pin bay. Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted February 8, 2006 Share Posted February 8, 2006 He's a member on here as well. Send him a pm http://www.ultimatesubaru.org/forum/private.php?do=newpm&userid=1032 Quote Link to comment Share on other sites More sharing options...
