eprom?

[ironryder]

how can i tell if i have a eprom ecu? and if i want to get dsmlink which chip is the one that i send in or need socket?

If that is a picture of your board, then YES you have an E-prom. It is the chip in the lower right hand corner. You don't send a chip in to get socketed, you send the board itself. The DSMLink chip will replace that chip you see now.

If that is a picture of your ECU that IS an eprom. To get a chip or DSM link, you need to get it socketed (basically desolder the pins and insert a socket so you can insert/remove the chip). Shouldn't cost much at a basic electronics repair store. This isn't something for a novice(you couldn damage the board). To get a socket made you need the whole board. You have to desolder the pins on the chip (big black thing in the lower right) and solder a socket that you can put the chip into.

yes that is my ecu ,so what are the benefit i have over the non eprom?i can use a logger or program it or something?

 

[VPrime]

i think the benefit is that you can use dsm link and other "chips" to control ECU/ tune..
you can use a logger with out eprom

In an eprom ecu you have a one chip that stors the memory and maps from which another chip, the processor or brain, looks at and determines what to do with itself. By having an eprom chip in your ecu, you have a way of modifying the "Cookbook" for the ecu to look at and make a new "recipe" for it to follow. Which makes it so you can tell the ecu that you have installed larger injectors, you have removed a sensor, you have added a sensor, you wish to change the fuel/timing, you want the engine to rev to this new rpm before cutting the injectors off, and on and on.

A piggy back is a device that works with either an eprom ecu or a non-eprom ecu by intecepting the signal from the mass airflow sensor and manipulates the signal so that the ecu thinks less air is coming in. Thus, the ecu dials back the injector flow allowing you to install larger injectors. This has the sideeffect of causing the ecu to operate on a more aggresive timing map that is meant for the smaller amount of airflow the ecu is seeing. This can be very bad once you go really big on injectors. A rule of thumb is that any thing below 650cc is ok with a piggly back (no typo). Often times guys still cant get a good cruising and idle tune with a piggly back and upgraded injectors because of injector deadtime. With an upgraded injector, more often than not, it takes longer for the electric puls to open it to put fuel in the engine. If this deadtime is not calculated correctly by the ecu then you have a hard time getting the right fuel mixture to idle and run part throttle.

Of course, if you have an eprom you can tell the ecu what the new deadtime is with your larger injectors and advance the timing only when you want, which gives it a smooth running factory-like tune for low loads.

All ecus can run a logger. DSMLink, which only works with an eprom, is considerend better than some complete standalone ecu systems and has the best logging software hands down already incorperated in it... go to dsmlink.com for more info on this. If you get dsmlink you'll be spending the same amount of money it will take to get a decent logger, a chip burned for your injectors, and safc to fine tune the setup. You'll all get alot of other benefits like logging esternal sensors like a wideband o2 sensor for air/fuel ratios, and more. It has no-lift-to-shift, antilag, nitrous and water/alky control, and on and on! bEsides as somepoint youll want to upgrade your mass airflow sensor your stock 1g overruns at around 300 crank horsepower. You can get a chip burned for a 2g maf, but dsmlink lets you add this sensor when you want and the maybe later you can go to a gm MAF and run blowthru if you want... the possibilties are endless

. . . end comercial

I really love my dsmlink.

 

[ironryder]

thanks for the great info...just one more thing,i thought you can run a blowthru on dsmlink alone without gm maf?

 

[megadeth0]

NO, you need the sensor. You also need the MAFT to run the sensor. We are hoping to have direct plug and play compatability in the next version the Link. But for now you need the MAFT if you decide to run the GM sensors.

 

[ironryder]

cool...i guess i'll wait till the v3 to get my dsmlink

You could be waiting a long time then . I believe they are going to bring out the new 2g model first, then the 1g. The new 2g version has been in talks for quite some time now & I still don't think they know when it will be finished.

 

[JCMDSM]

Thats not entirely true. I emailed the guys at ECUTuning and they said the new version with MAF compensation was about 4 months away. This was nearly 2 months ago. If they will release the 2g version before the 1g or both at the same time I don't know. They will of course provided upgrades for ~$50 is what they told me.--Jon

 

[dsm-onster]

Yea Daren, I was told by one who emailed tom that it would be out probably by the end of April. But thomas did leave that up in the air. . .

 

[megadeth0]

They have been saying 4-6 months away since last year at this time. I hope it's only a couple of months away.

HAHA! true true. it could be just a simple stunt of marketing genius

For those of us who already have DSMLink, will we not simply pay for an upgrade? or do we have to buy into the whole thing again?

Yes, that was exactly what I was saying. I too can't wait to get a hold of the new version once it comes out, the sooner the better Not that the current version isn't amazing, I just like new toys.

dsm-onster I would imagine it would be the same as before with the swap from V1 to V2, probably ~$50 to get the upgrade, as it would be both a hardware & software upgrade (software part is free)
