DSMlink Or AEM EMS??

[Hal]

I don't understand how people can define DSMLink as a piggyback device.

It doesn't tap into any wiring.

It is in fact an OEM ECU with a chip that permits certain parameters to be altered via an external device.

Hmmm... kind of like an AEM which is a non OEM ECU that permits certain parameters to be altered via an external device (laptop).

Both plug directly in the the oem wiring harness as a REPLACEMENT for the ecu that used to be there. DSMLink requires REPLACING an eprom in an oem ecu, but the end result is still a single device capable of managing the engine.

A piggy back device is one that taps into the existing harness and operates in conjunction with the existing ecu. Things like AFC, PMS, XEDE, EMANAGE, etc.

If you remove the piggy back device, the car will still run with the OEM ecu.

Unplug the DSMLink or AEM and the car isn't going anywere under its own power.

Go with the aeromotive eliminator pump.

Do you have any reasons why he should go with that specific pump?

DSMLink = WOT tuning only

Timing corrections are all the time, fuel correction are WOT only.

DSMlink is a piggy back.

We are NOT going to get into this again, if you want to discuss that Email Tom or Dave from Dsmlink and talk to them about it.

The stock computers tables will always try to optimize the fuel to burn at 14:1

It's 14.7:1.

We want to run external pump.. what one would you recomend

Product Engineering, MagnaFuel, or Weldon. When choosing high horsepower pumps it's best to look on the forced induction V8 forums, 1000whp street cars aren't uncommon so there is a good amount of information there. The pumps I named are just reccomendations, research those pumps and the Aeromotive's and see what you find out. Try LS1Tech.com, or corral.net

If you plan on having somebody else tune the car, you will get a more accurate tune with the AEM, and have a lot more options. But you can still go really damn fast with Dsmlink.

AEM gives you the one biggest advantage that dsm link DOES NOT. Full control of timing in every cell allowing you to properly tune the car along with the fuel and almost anything you can imagine, I run one personally.

Jim, could you explain why DSM Link is unable to do anything else in regards to idle? Are there simply different/more features with AEM's EMS when compared with DSM Link? Did the makers of DSM Link choose not to add such features because it is pointless for daily driven vehicles, or because there are other ways to alter the computer to see factory settings?

Both of those are being addressed in the next version. There will be more timing control and more options for idle control. They didn't add the feautures because at the time there wasn't much need for them, and they probably didnt want to deal with the additional support for such a little gain.

OK! Sorry I missed the .7, I should have said stoich to remove any confusion.

I didn't post this originally, but The "normal" A1000 will not support enough flow for a gt42r at the amount of pressures we would need to run with it.

I figured I would throw that in there for the benefit of all readers, as I'm sure a lot of you already knew that information
