Hey everyone. I started reading the archives to get to speed on everything. I'm on post 167 now... I'm a computer science major at VCU. I will be a senior...

It looks like there is an extra register as well, some functions seem to be taking in an extra register argument. <pre> ldc: cd ce hh ll load reg C with...
If you look at the photos section it looks like someone had prototyped one. If done the same way its done one ford ecus, I belive you have a CPLD that ...
well i've read thru the archives also and so far the "extra" register has been called Y, Z, and C. i believe it is in fact the Y register just because there...
www.pgmfi.org has done similar for certain Honda ECUs. It would require pulling the MCU and doing one of two things: fitting it with socket and a flash...
This sounds like something we could do pretty easy and make the boards available. Anyone have a 1 or 2 good non EPROM ecu's they would sell, all mine are EPROM...
well for cryin out loud ive been trying to get this done for 6 months :) , but no one will sell be a bad eprom ECU to research on. I'll be darned if im going...
I bought 5 from a guy not really knowing what they were but the price was right. All 5 were EPROM units. I don't have a non-eprom :) Mike ... From: Andrew To:...
When you say pull the Mcu, Are you talking about the entire ecu circuit board? Could someone develop a daughter board that could be soldered in the normal...
What you'd normally do is build a little board that had the same pin pattern as the non-eeprom processor. On that board, in addition to the pins which would...
On Wed, 3 Dec 2003 14:46:40 -0500 ... Ok, this begs the question...is finding an EPROM ECU such a problem that there will be a demand for this board? :) Josh...
... If you have a "normal EPROM location" you don't need a daughter card. The non-EPROM versions of the ECU don't have a "normal eprom location" on the PCB so...
assuming we do indeed have to replace the MCU (which basically means no adapter.. because where the hell will we source an obsolete proprietary MCU if we cant...
Wow, I didn't think my simple question would lead to such brainstorming. I fully expected a "get the hell out of here response" :) It's good to see some open...
This may be a basic question guys, but humor me. :o) In the E391 dump in the files section of the yahoo group, it is more than 50% empty space (the first half...
I thought I'd post this link here: http://pgmfi.org/phorum/read.php?f=5&i=3968&t=3968 Would be totally adaptable to Mitsu stuff :) HELL of a lot cheaper than a...
i found this page in one of my searches on the 68hc11. check out note 22 at the bottom of the page. probably did the same for mitsubishi with different...
Ok, I follow, thanks for the help thus far. Now, as such: With the code on a 32k chip, and with the code in the second half of the 32k chip, the addresses for...
Hey guys, good news! With the help of the archives (mostly information given by Jeff, but not solely), I have found the address for fuel cut and for injector ...
