New car with DSMlink, please help!!

[szewczyd]

I just got home from buying a 95 TSI AWD. The car has a 6 blt swap so the previous owner put dsmlink in the car for tuning. Will test driving the car it was runnign great with no real visible smoke adn ran very smooth. He had the Stock boost guage reading LTFT. Driving around town where he lived, with him it stayed almost dead in the middle whenever I was watching it. Upon driving home I started noticing the needle get higher and higher after each hour or so, until get got nearly peg all the way to the top, the positive side. If I let off the gas, while in gear it goes back to the middle. At idle while no in gear its almost to the botom of the guage. I didn't change any settings, due to the fact that I am unfamiliar with the system, I know very little and the instrucions didn't really help me much. As of now I take off decently boosting jsut a tad it will blow black and smell of gas, yet it reads almost to the top of the guage which in not mistaken is lean. I pulled two plugs and then are very light colored. Please help anyone.

-I assume, having the guage in the middle is considered right no or zero.
-Should I just unplug the battery and start over, If I unplug battery is that like running a stock fuel system and all?

P.S I did come from near 60 degree weather to low twenties. Not sure about the altitude
Mods will be listed in profile in a second.

If you unhook the negative terminal on the battery and reset a DSMLink ECU, it goes back to the default settings that were programmed into it when it was purchased. You'll need to find out if the original purchaser had the ECU chip burned for the size injectors that are in it now, and for the CAS inversion.

Also, you need to work with him on talking to the DSMLink people to get ownership transferred to you so you can join the DSMLink forums. That's the best thing you can do, since that is where all the DSMLink people hang out, including the guys that developed it.

And yes, if the LTFT reading is toward the top, that means the ECU is adding fuel to richen things up (middle is zero, bottom is taking fuel out). When my alternator went bad, my LTFTs went way up, I'm assuming because the ECU was trying to run very rich to keep the car going.
