Help me pick my engine management

[98spydert]

I don't see how you can set it for different loads i.e. low vs. WOT. Does DSMlink give you this option(honest question)? I like having the ability to adjust my fuel for the daily drive and at the same time have it already set for WOT when the occasional opportunity meets me at the red light. Besides, the ECU + interpolates the percentages between settings so if you look at it that way, you could consider it tuning even inbetween the 250s. I assume dsmlink and other management systems do the same. Is this how you are figuring every 40 - 50 RPMs or is this Image from dsmlink.com "outdated"?

I think he was refering to logging all parameters ever 40-50 rpms. That picture is outdated but the rpms points won't be updated until the next version release where they will be at least every 250rpms.

EDIT: Never mind, I reviewed a log and get a frame every 5-15 rpms. Not sure what he was talking about with 40-50.

As for adjusting for the daily drive, it's called Global and Dead time adjustments. These two simple adjustments can let your car idle and drive perfectly with 1600cc injectors. Try that with a piggy back hack. And you don't need to send your chip back to be reprogramed for different injectors, you simply grab that slider for global and set it to the percentage difference you need. After tuning dead time according to the DSMLink manual and getting the global dialed it by logging, the car drives as if it had a stock fuel system.

The one thing that sets DSMLink above ANY piggy back including ECU+ is fuel adjustments independant of airflow. No hacking the airflow signal to adjust the amount of fuel you get. You modify the ECUs internal fuel maps, effectivly modifying the injector pulse width. The ECU sees true airflow and uses the correct timing maps and fuel enrichment maps.

After looking at the ECU+ site, I wouldn't say the Palm client is aftermarket at all. The Palm client is fully supported by it's own forum in the DSMLink support forums (The BEST DSM forums on the internet in many peoples opinion. Awsome people on that board including Thomas and Dave who always help. None of this constant flaming BS that goes on here either ).

The price listed for an EPROM is a little misleading. I don't think I've ever seen an EPROM go for $350 and almost always for $225-$250. Hell, FFWD has a special on them for $200 a piece a while back.

Question for the ECU+ guys, the FAQ page says it can't log fuel trims How do you tune for daily drivability if you don't have a WB02 and can't see STFT and LTFT?

Also, the raw signal from the knock sensor is worthless without the ECU. Will the future knock logging ability simply be an estimate of knock retard displayed by ECU+?

I think I'm damned-if-I-do and damned-if-I-don't on this one. As I said above, I want folks to know that the Palm software is an integrated part of the ECU+ package and not the DSMlink. Seems like people get hot and bothered no matter what I put down.

As the page says, that's what Extreme sells them for, and I know they're a preferred DSMlink vendor.

I'll be happy to answer your questions via e-mail or on the ECU+ forums. Vendors on DSMtuners aren't supposed to discuss new features or compare their products to others, so I try to steer clear of that here. I did want to find out if I had any errors in the web site, though, and it seems like some people thought I did.

So, I have a number of mods done to my first gen Eclipse and one of 'em is the STAND ALONE AEM EMS. To be honest, I wish I had gone cheaper. Something like the DSM link. Don't get me wrong, the AEM does a hell of a job, but for the price... nah. My car does run better than stock in my opinion. However, the AEM is temperature sensitive. My other concern, it's hell to start it up and especially when it's cold. A normal car you'd crank for what, one second? My car you crank for 3-5 on a good day. If it's below like 60 degrees outside...5-8 seconds. Yeah, my car might look hella good and be wicked fast, but to the casual observer, it appears to be a piece of **** 'cuz they think I have engine problems 'cuz of the start up. Other than these three negatives, the AEM is a hell of a system though. Lot of options with it...

Correct me if I'm wrong, but isn't ecu+ the same as every piggyback system, in that it modifies the airflow signal to the ecu. This isn't to bad if your running smaller injectors such as 550's but when you get into larger injectors you have to compensate by removing so much fuel that the ecu thinks it is seeing alot less airflow then it actually is, therefore giving you too much timing advance. Like any other piggyback your timing maps will look like crap & it will be hard to tune. DSMLink doesn't suffer from this at all, you can run basically any injector you want & still have it drive like stock.

To GoodGuy:

Your starting problem doesn't have to do with the EMS persay. The problem is in the crank inject time table I believe. You also could look at your fuel inject warm up table and raise the percent fuel that the engine receives below 60 degrees. I just wanted to clarify to everyone that this is not something that cannot be fixed with a little tweaking.
