With ECMLink's narrowband simulation function, you can simply run the 0-5v output to the ECU and then configure the ECU to produce the 0-1v simulation internally, thus freeing up an additional input on the ECU for some other aftermarket sensor. | With ECMLink's narrowband simulation function, you can simply run the 0-5v output to the ECU and then configure the ECU to produce the 0-1v simulation internally, thus freeing up an additional input on the ECU for some other aftermarket sensor. | ||

To correct for this, you need to change how the ECU adjusts the short term fuel trim. You do that in the STFTAndO2Feedback panel in Direct Access. The following illustrates a stock 2G DSM configuration. | To correct for this, you need to change how the ECU adjusts the short term fuel trim.

You can try slowing the adjustment rates down (there are a lot of them) if you want. But your best bang-for-buck change will be to the **O2FeedbackAdjRate** table. Try values like 10 and 16 or 14 and 18 instead of the stock values (4 & 10 shown in the 2G example above). | You can try slowing the adjustment rates down (there are a lot of them) if you want.
