General Evilscribe (ECU chip burning)

[timloomis]

Just got my eprom ecu and I want to start making chips for it asap.I just downloaded tunerpro(free),but I wanted to get ahold of evilscribe to compare the two.I see that their site is down,so does anybody have a copy they can email me or anything(its freeware).What do you guys use to burn your eproms with?

 

[awdtalontsi1992]

Burning chips could get kind of expensive if you are changing parts often. I would recommend you try an emluator such as the Ostrich instead. There is a new engine management system in development by a bunch of enthusiasts that we are trying. It uses an Ostrich and a program called DS-MAP to change settings inside the factory ECU. The site is http://www.ds-map.net if your interested. All the information is on the site.

The chips are re-useable so there is nothing expensive about it. Evilscribe has been gone for a while.

 

[awdtalontsi1992]

I was under the impression that the chips could only be burnt once. Is this true or can they be reburnt?

 

[Defiant]

Depends on the chip. Like CDs.

If your doing development you use either the UV erasable 27C series parts or electrically erasable flash 29C parts. The One Time Programable (OTP) EPROMs are just the UV parts in a cheap package that doesn't have the quartz window used to erase them so you get one shot.

The Ostrich is great but unless your using it for real time changes burning and erasing is just a little slower and a lot cheaper.

Thats what I though,price wise at least.Theres about a $100 difference between ostrich and the moates burn1.I was just a little confused about the way that tunerpro works.Like do I have to change EVERYTHING thats on the chip?Im just interested in studderbox,injector comp,rev limit,fuel cut removal,etc.. for now.I dont feel like messing with fuel and timing tables,at least not for now.Like with fuel cut removal,it says 2.5 g/rev now,do I just raise that to say 5 to get rid of fuel cut or something?I just though there would be a drop down menu that would say fuel cut removal,injector size,etc...

Evilscribe was a nice tool but tunerpro is where the whole ecu list went. It keeps getting better too! You can burn the chips if you like or go realtime with an ostrich and tunerpro rt!

 

[Caithness]

I still use evilscribe to do the fuel and timing. It's not perfect but it's easier than copy pasting straight hex at the track. I might check out tunerpro but I'm lazy and the setup I have doing fuel and timing through evilscribe and everything else in hex works well for me. If you still want a copy of the software, I could throw it up for download, but I agree that the best route is probably to figure out Tunerpro since it's what everybody else is doing. Evilscribe has a few bugs and it's not very polished.

 

[timloomis]

Im just confused on the "hex" part of the whole thing.Its says something about raising the g/rev when you use the extended maps.I dont have a clue on how/where to put that in at,or even if I have to.I opened the hex editor,but have no clue where the adress of anything is.

It sounds like you're ready for this page. users.wpi.edu/~ktarry/dsmtech/dsmromedit.html
You might want to save the whole page so you can go back to it quickly. Make sure you check out the links to the Extended Map Guide and to the DSM-ECU mail list at Yahoo, there is plenty of good reading in the archives there. The work is mostly done in hex, addresses are included.

 

[GVR4592]

I think it would be pretty sweet if a group of guys got together and wrote a rom editor for the Dsm ecu. All of the information needed is out there, it's just a matter of putting it all in one place and writing the application. That's how a lot of the Honda editors came about.

 

[timloomis]

I think I'm starting to get it now,the hex is starting to make a little more sense now.thanx guys.

 

[BISHILVR]

I have most of the adresses for the 1g, how far away from me are you? I've done alot of eprom editing and am very familiar with it, if you were close and had to have a hand we could meet up maybe.

 

[timloomis]

Im about 10 miles south of Zanesville,which is an hour east of Columbus.I'm not gonna start burning chips anytime soon though,I still have to get it socketed since I just bought the ecu.I'm just trying to read into it more so I know what I'm doing when I start making my own chips.

That car looks familiar,was it in Mansfield at the bike night?

Okay maybe everyone skipped over it....

It's done, out, used, and works very well. In the old days of 1G eprom editing yes, you got out a hex editor, went to the address of the code you were trying to modify, and replaced the code. It was very specific and one screw up could = poof... Now you can use tunerpro and just modify everything through the front-end GUI. Once you change what you want tunerpro modifies all the code for you and saves it as a .bin file. You're done!

Tunerpro and or Tunerpro R/T (for realtime) is your rom editor. You simply load the .ecu file, the .bin file, and then adjust fuel, timing, add stutterbox functionality if you like, adjust for different air flow meters, change rev limit, tune by target AFRs, different injector sizes etc. It also uses extended fuel and timing maps and it's free.

If you want to change all of this in realtime (much like dsmlink) then you download tunerpro r/t and but an Ostrich (chip emulator for 170ish) and you're ready. You basically have all the functionality of the dsmlink and much more for 170.00. It's an awesome resource that few use.

Want a look, here you go.

 

[GVR4592]

I played with it when it first came out and it didn't really work on Dsm's, so I'm not really aware of what it's currently capable of doing. I use Crome for tuning Honda's and I was thinking something similar to Crome Pro would be nice for Dsm's.

 

[Street Surgeon]

When it was really new it wasn't so hot and there were a few bugs, that has since been worked out for quite some time. If you like or think DSMlink is a worthwhile product, here's a solution that's quite a bit more powerful, and for about 1/3 the cost for the "realtime" version with the chip emulator. Free if you don't mind burning eproms.

 

[GVR4592]

Can it implement the no lift to shift feature and can it datalog?

 

[Caithness]

No lift to shift is a very simple extension of the stutterbox in the code if you're willing to run a wire from the clutch switch to the park/neutral input. The code is on the list and so by extension is probably in the Tunerpro file.

I'll have to check out Tunerpro again. When people first started using it the definition file was crappy and didn't have much in it and I just kinda shrugged my shoulders and kept doing things the way I was doing them. I should get back on the DSM-ECU list and read up on what people have been doing recently.

None of this DIY stuff has the awesome datalogging capability of DSMLink. It's all still through the stock logger interface, unless some miracle breakthrough has taken place in the few months I haven't been reading.

 

[wortdog]

I've been using TunerPro R/T with an Ostrich for a couple of years now. It works great, more capability than DSMLink for 1/3rd the price, as long as you're willing to devote some tinkering time. You can even make the switch to speed density or run a GM MAF with no translator if you're really feeling adventurous.

Yes, out of the box for a normal user, DSMLink is better.

I haven't really been wowed by DSMLink's datalogging on the cars I've messed with it on, at least not enough to tout it as a huge advantage over the Ostrich/TunerPro/MMCD setup. MMCD with a wideband O2 plugged into the EGR ECU input is plenty to tune a car with.

Agreed, for me the dsmlink is overrated. With all of the other options currently on the market, I just cant see people still swinging off the dsmlinks nutz, but thats me.

 

[Street Surgeon]

As far as I know it does not have datalogging yet, but that's what dsmlogger is for, hell throw a wideband on the EGR input and you're good to go. If you want you can buy mine for cheap with the palm since I no longer have any use for it

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.

 

[timloomis]

I think I'm starting to learn a lot more about tunerpro.Do those fuel and timing maps make a big difference?I'm planning on using them along with the studderbox,fuel cut removal,injector comp,etc..Now I found my deadtime is 180 (rc 550's),how do I plug that into the deadtime table,since its all different voltages?And I couldnt find anything on maf compensation for my maft setup,should I just leave that alone?
