Hi guys. Just joined the list today. I've been wondering what speed parts are useable in the 1G ECU's? I've got a couple files I've played around with (also...
Welcome Hop, I've been using -15 parts myself, or better. The CPU internally runs at 3 MHz, I believe, so if anyone knows how to calculate the EPROM speed from...
I will get back with a clean copy of the EA01 this week-end Jeff. Also I have in my hand a 2G EPROM ECU which I will be able to copy also this week end. I'll...
Which timing map is used under normal (ie low air temp and no knock)? I think I remember that there is one "ideal" map that is never reached. Also, let's say...
When the ecu sees knock, it starts subtracting timing right? It doesn't jump to a different table does it? Jeff Oberholtzer <keydiver@...> wrote:Jason, ...

Hey guys, I updated the basic info file, located here: http://autos.groups.yahoo.com/group/dsm-ecu/files/Basic_Info I also made it so that it gets sent to...
Hi everyone! This site is going to take a while to absorb, especially since I don't know anything about this :). That sort of thing has never stopped me...
I think, in the bottom of my closet lies a Motorola HC11 developers kit. I may actually have to dig it out and power the thing up. I know it has at least 1...
... Yes it is HC11 based but it also has enhanced instructions that the HC11 language does not have. I think there are 6 or 8 instructions we have not been...
You don't need someone internal to Mitsu to figure out what those special instructions do. Just start going through the code, disassembling and figuring out...

I was given an ECU to take a look at. It has a Todd Day modded EPROM. Turns out the ECU is good & the EPROM is bad. I don't mean the part but the actual code...
How difficult is it to compensate (in the code) for the 2G MAF without switching to 550 injectors? I don't really need those injectors on my 1.6L engine, but...
Well if you could get a dump from a 2G eprom and isolate the MAF table they might just be the same size as the 1G unit. If they are just cut and paste to...
yeah, that would work, I'll look into that some tonight when I get home. I thought someone was mentioning a multiplier for different sized injectors. I...
Jason, The right way to do it would be to add a subroutine that would take the airflow value and multiply it times 1.2 approximately. That way it wouldn't mess...
Well depending on where he got the Chip because I was told Todd put in some copy protection to prevent piracy on his code so if his code wasn't legit that very...
Hi I'm new to the list, just like to add that there's no such thing as copy protection on Eproms. Steve ... From: berserko_1 To: dsm-ecu@yahoogroups.com Sent:...
Sorry to kinda drift off topic here. Does anybody have a *DEAD* 1G ECU laying about? Want to get back a small return on your misfortune? Feel like boxing it up...
... Well, not in the strictest sense, as an EPROM you couldn't read would be kind of pointless. Since Todd modifies the program itself, it'd be a relatively...
Since the group description says so, I'll introduce myself. I'm Matt Ahl from NWDSM and have been looking for a board with technical ECU content like this for...

I just joined as well. Knowing more about the stock ECU is always good information to have. I'm a member of Michigan and Cleveland DSM chapters, and have...
Steve: According to this note written by Todd Day he has written in protection into his software. http://www.stealth-3000gt.st/digests/v01n699.htm It reads as...
I remember that post, but I don't take from it that Todd has "copy protection" in the chip. Since he scrambles the addresses differently in most chips, and...

Things here have died down. If you're all as busy as I am, I totally understand. Just in case someone has the time, I uploaded that bad TMO eprom. I figured...
