aldu1/cabl1 affects tune

[JamesRed86]

tuning a 86 f body with oem ecm with ostrich 2. it requires the ten k switch to on to log. I have noticed that simply plugging in the cable,will change the rpm,also the car will not run the same ,lack of power when unplugged. what is the cable doing when plugged in?
second question, what is the unit of measurement on air flow with tuner pro rt ,and can it be changed?

After you connect, you can disconnect the 10K. That'll help the running issue when the cable is connected.

Also, for some masks, there is a spark adder in ALDL mode. In $6E, I zero this value out.

I'm not sure if this exists in the $32 mask. It'll have to be a point of research for the reader. =)

MAF airflow is typically grams per second. The MAF tables are usually displayed in volts. Lots of info on this over at www.thirdgen.org/techbb2/diy-prom/

thanks Mangus. I just tried turning off the 10k switch after connecting and i get an error and no data. i am using $6e .
I'll check out that maf info .

If you have a 1227165 ECM, I recommend using a 6E tune, then use 8192 baud. Unplug the cold start injector, since it isn't used in the 6E mask.

With that, you only need the 10k while connecting to t he 8192 baud stream. Once you start getting data, you can remove the 10k.
