Blog Post: Scan E3C – consistent with 3B

Recommended Posts


Scan C is a repeat scan for Tune E3. There were two runs in C, one of which is shown above. Both done in TUTD auto (sport) 3rd gear. Results are similar to E3B, smooth acceleration to redline, minimal KR, no torque management advance (TMA), good boost.

Bank 1 is still running a bit richer than Bank 2 after the sparkplug change judging from a higher narrow band O2 (example 952/883 mV). The LTFT look fine, single digits. The NBo2s are consistent from wide open throttle (WOT) run 1 to run 2.

With correction day to day I am seeing very consistent scan results, which will help for comparing changes.
