Got ista working.... confirmed that i can communicate with the dde...
Does the procedure below look correct. I got it from an e90 post with a 335d...same engine.
"I just about forgot how to use ISTA+ to code my injector so for ease of reference, instructions below:
Warnings for ISTA+:
- Compatible K+DCAN cable required
- Keep a battery tender on your car. Turn off lights, radio, hvac, etc... to preserve battery power.
Not doing so can result in a fried DDE and a dead car. I'm a rebel though and did this quickly without a battery tender.
1. Vehicle Information (You must first pull all fault codes.)
2. Navigate to:
- Vehicle management
-- Service functions
--- Digital Diesel Electronics
----Adjustment functions
-----Injection quantity compensation
3. In the right panel, select "ABL Injection quantity compensation", click "Display"
4. Click "Continue" after observing your current injector calibration values.
5. Select "1" To update your new injector calibration value and click "Continue".
6. Input the cylinder number for which injector you are updating. 1 is at the front of the engine, 6 is at the back.
7. Input the new Injector calibration value.
8. Save your new value.
9. Turn off the ignition.
10. Turn on the ignition.
11. Exit ISTA+."
