ECMlink More Dsmlink Log help Please

[crazyquik22023]

ok so my car runs and idles good now but i am running ridiculously too rich my a/f is between 20:1-35:1!!! Also i have no idea why my timing is soo high.. I'm new to tuning and I'm trying to get my car running good enough to make a 1hr 30 min drive to buschur racing to have them tune it up good. any info would be greatly appreciated thanks. Here's the log

you would have much better luck posting logs on the dsmlink forums.

Well, you don't have the newest firmware version. I would recommend upgrading your software to the latest version, and then upgrade the firmware.

The reason you're seeing those high readings is because the properties for the AFRatioEst are set for stock injectors. That is how it comes, so you need to double click on that value in the table below the graph and adjust the properties to mach what's in your Fuel tab.

Or, just upgrade to the newest firmware as the new AFRatioEst doesn't utilize user-input properties, so you don't have to adjust anything.


Also, use the TPS adjust wizard as your values are pretty far off.

Relax and take a breath.

20-35:1 wouldn't be rich, it would be lean. It's also not accurate.

What MAF is on the car?

Don't worry about timing at idle, unless you see some ridiculous problem, or the car knocks. The car will take care of that.

Your profile says you have a wideband, what does it say?

ya sry that would be lean, also i dont have a wideband anymore i just have a narrowband now, but it reads completely rich and it def is b/c black smutt is shooting out my exhaust and dumptube, also its a stock MAF through a 4" intake, and u are saying that i would be ok to drive for a while with the timing at 25+ degrees?

adjusted the TPS values and the AFRatioEst is set for the right injectors now.also downloaded the newest software. thanks

also here is the log with the updated AFR values for my fuel setup and as u can see it is running VERY rich.

I use V2 software, so im a little out of my element here.

With the stock fuel pressure and the global adjusted properly, you should not be running rich (although i see that you are). Recheck the base fuel pressure?

Also, your idle timing is at 15-16 degrees, only advancing beyond that when you're reving, which is normal. Under load, the computer will adjust the timing. I don't expect problems with the timing as long as you stay out of boost.


I would go to the DASH tab and set the knock CEL at 2 degrees, so you'll be warned of any real knock when driving.

See if you can figure out why it's so damn rich. Only things i can think of are MAF miscalibration, base fuel pressure, or improper global settings.

If all of that checks out, go for a brief drive and take a log (after setting the knock CEL at 2 degrees). Make sure the CEL isn't coming on when you're driving, which i doubt it will.

Do not hit boost...at all.

Post an update with a log.

ya the fuel pressure is at 43.5. and i have the knock CEL at 2 degrees i believe already but ill make sure and i wont be able to drive it for a few days b/c its snowing pretty bad but ill post a log when i do, and yes i wont hit any boost oh and could really bad spark plugs cause the car to run rich like this... i have a new set im going to put in tom. but the ones in there now are old and black

Nope, not the plugs, it's just getting too much fuel.

Depending on how rich it's really running, i'd wait to put the plugs in. You might end up with new and black plugs in about 10 seconds.

If the plug doesn't fire that fuel has to go somewhere
