Before buying a tuning tool, take a look at dsmap

[hakcenter]

This is my opening for the project "DSMAP" for 1G DSMs.

It is a completely free project, and I am in no way trying to directly influence anyone to buy or try this(cover my ass). But the means of this is to show people that something of this nature DOES exist, and it is not completely un-affordable at all, and is NOT A JERRY RIG.

Speed Density: what is that? Basically Speed Density is a different way to calculate AIR FLOW without needing to MEASURE AIR FLOW. You calculate pressure from a map sensor, over rpm and volumetric efficiency against a table.

Yes I know, 1G only... so sad, we only have the disassembly for the E391 e proms... and no one has any disassembly for a 2G that will email me it. 2G could be supported.

This is an on going project, things will be added, things will be taken away. We currently have complete native wideband support for the original closed loop operation. And working towards having closed-loop operation all the time for AEM style tuning.

Pros:
Quicker throttle response, because we have nothing restricting any airflow, and with a MAF, at 125 Hz, 3000rpm, you only have 1.25 maf ticks coming in per 1/2 revolution. If you accelerate, you will have to wait for awhile before the ECU can calculate the new frequency correctly. Not to mention that you have to wait for the pressure front to propagate from the throttle body to the MAF sensor.
The MAFs on our cars are finicky, restrictive, and nonlinear. The cars are old, and almost all of them have boost and vacuum leaks that render the maf signal inaccurate. A MAP setup will work fine regardless of leaks.

You can vent, without any negative affects. Since all FLOW calculation is off of pressure, it does not matter at ALL where air goes, as long as we can measure pressure, we can measure air flow.

Ya.. this is the killer... the project actually costs sub300$. The ostrich emulator, is a MUST have for this. Ya we could burn you an prom chip, but VE is different on every motor, especially when they are at different altitudes, etcs. So You NEED a way to adjust your VE for YOUR motor.

The ostrich only costs $175 and is sold by moates.

Next you need a MAP sensor and a IAT sensor. and bung your TB elbow for the IAT. That is IT. Once you have that, you can follow the directions on the dsmap forum @ DS-MAP.NET

Not to mention the program for dsmap allows complete control over:
Timing Map, VE Tables, Idle Control, Injector Sizing+Deadtime, and Studderbox, and many more features

v2 is on the horizon

[project_tsi]

Wow, I have been looking for a new setup to run a MAP/ speed density setup on. Is this a tried and true system? How many cars has it been installed/ hooked up on and does it work well? Does removing the batt reset all your settings?

[hakcenter]

Tried and true, I would have to imagine so, the creator of this entire project has over 1000 miles on his car with this.

I personally have ran 25psi on 91octane @22* of timing, all the way to 7500 rpms without a hint of knock.

The car count is low, cause no one knows about it, so hopefully this thread will bring new life to a project, and open it up to people of all types. All the cars currently running this are used as daily drivers, mine included.

Reseting your battery on the non-wideband ecu will reset any adjusted changes you made through the logger, after using the dsmap tool on your computer, IE re-adjusting injector deadtimes/injector sizes, studderbox. ( Yes this has a logger program built for PalmOS, that you can adjust your injector sizes and deadtimes on the fly)

[Bohrn]

Do you need another logger program or does this log everything you need?

will it work with a custom Eprom chip?

can you run the IAT sensor at the air filter or does it have to be at the throttle body? I ask because I run water injection and the IAT would be effected by the meth/water.

has anyone been thru an emmissions test successfully while running this?

I am not asking about other features at this point because its so early in your beta program. I know that will come, if the project keeps alive.

looking very good so far.

[hakcenter]

The beta of this, way over a year ago when it first started. I've personally been running this for 6 months.

The IAT can be anywhere you want but after the IC would be a much better place since the ECU we coded is for that.

All the cars in this project are DD, with the owner clocking well over 1000 miles on his car with this.

The Ostrich is a complete replacement for your eprom in the ecu. And a lot of the functions still left in the rom are completely stock.

Currently there is a logger, and others you could use, specific logger named pocketdyno which was created for this allowed on the fly injector resizing and deadtimes. Studderbox changes etc. Including its own built in dyno tool, that was within 1.5% of a mustang dyno.

I think you mean that the Ostrich is a replacement for the EPROM in the ECU.

sounds very cool

lots of options coming out, good time to be in DSM's

[JrCRXHF]

I did not want to make my own thread but has anyone been running this since 05


I might want to play with it instead of spending the money on DSMlink not unless V3 is going to be out really soon.

[tkelly27]

Funny, I had just looked into that yesterday.

I was kind of turrned off that there were no CEL codes. Any plans or ability to include those? OR if I have a logger will the logger catch it and save it instead of the ECU?

[danyz250f]

So more questions.

With the ostrich is the main tune by a laptop in the car? Then you make small ajustments with a palm, or can you still use the laptop?

As for the losing power, the ostrich has a built in battery that lasts like 30 years or so. Correct me if I am wrong. So once you have your tune and you save it or burn it to the emulator you are good, and you can take out the battery (for the car) all you want. But if you dont save it and take the battery out, you lose what you just changed?

As for a parts list you need?

Ostrich
Gm map sensor 3.3bar
Intake air temp sensor of some kind
free download
patience

This is freakin awsome news. My GF's car needs something and dsmlink is more than I want to spend on her. Plus this is speed density.

Also once you get your tune can you just use a chip burner and make a chip plug it in and put your ecu back together and forget about it, untill you make a mod change. If you get a boost leak you will just make less power right? Or will it be like a maf and make all sorts of problems?

Sorry for all the questions but I am kind of excited.


Im dumb this is old

if you get a leak the car will still run you will not get as much power but if you get a big leak like a pipe off you have to watch and make sure u don't over spin the turbo. My honda is SD and if i lose a pipe all i do is pull over the car keeps running and i can put the pipe back on if the dsm loses one i hope there is a good spot to cost to because the car pretty much does not run.

I really want to get a spare ecu and play with this.

This project is still very much alive. A lot of individuals that seeked help tuning their VE's essentially learned, and it makes it look like it is dead. On the contrary I'm in the works of recoding the dsmap editor in gtk+, I'm not going to lie either, it is going to take some serious time to rewrite just the editor. Plenty of people still run it, plenty of people still keep tuning their VE.

However, ya you can unplug your cars battery all you want, it is not going to change the ostrich coding. And yes, once you get your real tune, perfect (which is almost never), you could burn the chip code, plug it in, and sell your ostrich if you really wanted.

The editor is not completely specific to the dsmap ecu code, you can write out your own config files if you really wanted to.

2 word.................LOVE IT!!!

I have been running it for almost a year now. Throttle repsonse is much better. Tuning isn't hard at all. Very user friendly.

Those who don't have this, SHOULD!!

[Zenja]

I've definitely been planning to run this for a while now and probably will some time soon. I already have an Ostrich and tuning is going great with it. I might as well ask two questions that I think I know the answer to, but I just want to make sure.

1) Can Pocketdyno be run on a laptop? I don't plan on getting a palm, but I guess I might. Will running Pocketdyno through an emulator on a laptop work properly?

2) Is it pretty much necessary to have a wideband to tune the VE tables properly? It seems like it is for the most part. Well, it makes it a lot easier anyway. I could see tuning some parts by using the narrowband O2 and fuel trims, and then guesstimating and tweaking the higher points though.

I use PDyno on my cae pc using an emulator.

I ran the basemap for a month before i had my wideband. It was really rich, but ran well. I would highly recommend using a wideband to get the most out of your tune.

[wishihadatalon]

So this was from 2 years ago. Do you have the 2g support that you wanted before?

[Ghettodsm91]

ok i'm really looking into buying this setup. what all is needed? at least a 3 bar map, ostrich or some form of modulation and an iat. I'm an absolute noob when it comes to tuning anything. My vehicle is basically stock but i want to start with a good tuning device. This seems like a cheap alternative to dsmlink(and possibly better than dsmlink). Thanks in advance for all the help,
Kevin.

also you can't adjust the ostrich with a laptop or similiar device?

1) Yes
2) It is pretty much necessary if your going to be doing any WOT pulls, running on a NB and trying to dial in your VE, you only have knock to rely on, which isn't really tuning at all IMHO. That being said, you can definatly use the vehicle with a NB while inside the closed loop operation and tune your VE.

Not a single donated 2g to Nick yet, so nope. Probably won't ever see it, everyone is dsmlink at that stage.
