Re: Could someone take a look at this datalog?
The A/F ratio during the 2nd gear pull is actually fine, about 12.5. The only issue I see is that your closed loop correction could be improved. Go to the help section and search "Tuning AFM Flow". Looks like your mass flow in gram/sec should be reduced by about 10% from 1.4 volts to 2.4 v...

Re: FlashPro Requests
Flex fuel capability for 2018 Accord 2.0T would be great.

Re: CEL with P0101 code
Looking at the top image below, your AFM flow versus voltage graph is incorrect. Somehow is is all zeros. I would open a Stock Tune and copy the values. Its just a 2 row table with mass flow values for voltages from 0-5V. I strongly suggest you turn off all active tuning until you get this corrected...

Re: Adjusting Open Loop Fuel in AFM tune
Looking at this further..I think I have to recalibrate the AFM above 3.2 volts.

Adjusting Open Loop Fuel in AFM tune
Car is basically stock. All my tunes to this point have been speed density race tunes or AFM tunes that switch to speed density fuel tables at 74 kPa. No problems. I unchecked the "Use Speed Density (MAP) fuel tables" in the Calibration Fuel section just to see how the car would react. Dro...

Re: FlashProManager 2.8.4
Active tuning will use the external wideband for tuning if selected under Closed Loop -> Lambda -> Wideband lambda Input. That's perfect - thanks for clarifying! Note that this may cause problems if Active Tuning is used in closed loop and the factory wideband and wideband input are different. I've...

Re: FlashProManager 2.8.4
In the Active Fuel Tuning window, you can select what drives the target lambda for open loop (i.e., AFCMD or Target Lambda Table). Are we to assume that the primary stock sensor is providing the measurement for this? If so, that makes open loop WOT Active Fuel tuning pretty pointless. My wideband is...

Re: Using PLX Wideband as Primary O2 Sensor
I did get the wideband installed and it works great. I just wish I would have done it sooner because now I know why it was hopeless to tune WOT with the AFCorr signal.

Re: Using PLX Wideband as Primary O2 Sensor
Thanks. Looks like I'll be welding another bung on the headers I've got coming then. No problem. It all makes perfect sense now. Statements like "You cannot use aftermarket wideband sensors for closed loop control" are very black and white and helpful. I must have missed it somewhere in th...

Using PLX Wideband as Primary O2 Sensor
Getting ready to install the SM-AFR Wideband module and sensor. I will use pin B29 and ground the module at the same location as the ECU. I plan on just removing the factory primary sensor and placing the wideband in that bung on the header. I have a factory exhaust, so the secondary sensor will rem...

Re: When Will Honda Update the Stock Basemaps
OP, all I can say is...good grief. What about all the stock Si's that use the stock tunes that Hondata generously provided and those cars have no knock? Rather than spending months investigating Hondata's apparent neglect, why don't you just tune your car? If, and this is a very big IF, all other th...

Re: Here's my Datalog
A typical "pull" would be (assuming you are by yourself on a deserted, straight, flat, stretch of highway with a 70mph speed zone): put the car into 3rd gear, let RPMs come down to about 2500, start the data log, roll into the throttle quickly so that you're at 100% throttle at around 3000...

Re: Here's my Datalog
It looks like the O2 sensor works OK at very low loads. At medium loads the measured AFR starts to look abnormally lean and at high loads, the measured AFR is obscenely high. There is no way your engine actually needs that much fuel, unless you have a supercharger you are unaware of. You also have f...

Re: Here's my Datalog
I think you need to either calibrate your CAI so that the air flow is properly measured, or just switch to the MAP based version of the tune you have, which is "Civic-Si-Race-6-SkunkHdr"
