Changes from 2.8.0.0:
Download here
- FlashPro firmware updated to version 119
- [2016-2017 Turbo Civic & Si] Race FlashPro's can disable certain equipment.
- [2016-2017 Turbo Civic & Si] After reflashing knock control no longer resets to 100 percent.
- [2016-2017 Turbo Civic] Added support for 5AN-C73 Canada.
The release has some improvements for the turbo 1.5 owners, and a new tuning feature, initially for the 2006-2011 Civic Si.
With the 2016+ Civic turbo, after a reflash the knock control would always default to 100%. This would retard the ignition for some time until the ECU reduced the knock control. Now the knock control will default to around 55%, which sames a lot of time when testing, or on the dyno.
'Active Tuning' explanation to come shortly.
https://www.hondata.com/forum/viewtopic.php?f=29&t=20613Active tuning is where the ECU will tune the fuel tables as you drive, without a laptop and even without the FlashPro being connected.
It does this by using the o2 sensor lambda reading and target lambda to alter table values. You can active tune the fuel tables if using volumetric efficiency (MAP) tables, or the air flow meter conversion table if using mass flow.
Over time the quality of the fuel tables improves so that the ECU does not have to adjust the fuel values using the fuel trims as much. Here is a test we performed:
Short term fuel trim with a stock calibration:
After 5 minutes of driving:
After 15 minutes of driving>
Each test was made by driving the same circuit in the same way. A lower short term trim is better, and after just 15 minutes there is significantly less fuel trims being used.
We are going to trial this on the 06 Civic first. Other models will depend on the amount of ECU RAM and other factors being available.
