General Evilscribe (ECU chip burning)

[sbiggi]

You can do anything you want to with tunerpro, and learning how to edit the hex code.

I just implimented multiple maps on mine. Flip of a switch and I have different timing and fuel maps for pumpgas, racegas, pumpgas with nitrous, racegas with nitrous.

Plus extending the timing table from 7000rpm to 8500 rpm makes tuning a lot nicer.

Tuner pro rt comes with the maftpro, yet another reason to get on the maftpro bandwagon!

I'm glad you like it I didn't get any feedback on the DSM-ECU list, it's nice to hear someone else finds it usefull.

I wish I had it the first time I used nitrous at the track.

When I hit the last timing row and airflow fell of, my timing went way up.
26 psi, and a 55 shot.... 27 degrees of timing is not good.

Dont have to worry about it now.

Thanks for the code! Simple change, but made a big difference for me.
I was able to figuer out how to do multiple maps from that too! Someday I'll stop being lazy and read the whole disassembly.

Does anybody know the code to change the boost gauge to knock?I cant find it anywhere.

extending the map from 7000 to 8500 rpm is that part of the extended map code or a seperate code ??

It's nice having full control of the timing. I like to think of the eprom as a DIY standalone.

I keep thinking the same thing, that I'll read it from top to bottom. No way! YAWN!!!!

When I get an idea for some code I'll just search the document for certain keywords, like 'TPS' and see where it takes me. I'll usually read a little above and below a section to get an idea of what's going on. It can be tough when the code jumps around for table lookups or jumps to another subroutine. But it's also interesting what pops up. Like knock decay. Have you searched the DSM-ecu archives for knock decay? It's fun to cross reference some of the older posts with the recent disassembly to see if they match or not.

It's seperate. I posted the code on the DSM-ECU list at groups.yahoo.com

It's very sweet. My friend is going to be running his car up to 8500 pretty regularly when he gets his SCM61 on and we've been looking at that 7000 rpm point shaking our heads thinking about how it would have to cover another 1500 rpm. Now he's pretty much set. Good work.

I've always felt like I should read that disassembly but I've never gotten around to it. Sad to say after the dozens of hours I put into reading the DSM-ECU list at the beginning and learning the basics of coding I got lazy and stopped playing around with the code once I found that everything I wanted to do had already been done by somebody else. I sometimes feel bad for leeching off of developents people like you make when I could be experimenting and coming up with stuff to contribute.

I'm with you on that one. IMO a well tuned eprom can do just about anything that a standalone can, which puts it well beyond the capability of dsmlink. The DSM-ECU list has even come up with a few tricks that DSMLink can't duplicate. Just having full control of the whole fuel and timing maps is way better than what dsmlink can do. Plus an eprom gives you the potential to change anything the ecu does, as long as your can find it in the disassembly.

The next version of Dsmlink is going to have full control of fuel and timing maps, along with a dozen or so other very nice features.

 

[talon1987]

is there a release date for the new dsmlink yet??

Yes there is, I believe it is ummm the day after h3ll freezes over.

Kinda old thread but I have a related question I haven't been able to find an answer for. I already have an EPROM ECU and am interested in working with the Ostrich/TunerproRT set-up when I drop in my new motor.
My questions are about the hardware requirements: Do I need some sort of special EPROM? How does the Ostrich interface with the ECU?(Through the datalogging port? If so does the Ostrich come with a cable?)
Basically, I want to know, do I just buy the Ostrich, plug it in to the data port/laptop and start editing the ROM through Tunerpro? (Obviously, with an understanding of what you are editing beforehand.) Thanks in advance for any answers you guys can offer.
Aloha

Yup, the Ostrich emulates the eprom chip so all you have to do is plug that in where your chip went and start tuning in real time. When you're done you can pull it out (or leave it in since it has a battery backup), use the settings that you have saved in tunerpro r/t and then burn an eprom chip to put in permanently.

Another sweet thing is you can have multiple maps on a single eprom (if you run the right chip of course) and can switch between maps via a toggle switch. There's a little info on dsmchips.com on how to do this, and it seems that there's a plug and play solution for that on the moates.net products page as well!
