Can you swap the fully enclosed stock intake back on for a test? I have heard a report of a user fixing his 'false knock' issue by switching back to a stock airbox.

Thanks!

OK, thanks. Is the standard AF accurate enough to tune Open Loop fueling? Would love to keep it simple and not have to integrate a Wideband O2.

Sorry for asking the same question in a different way. I want to know the difference between AF, AF.Cor, and a 'true' Wideband O2 reading, for an S2000. How does the standard AF readout for an S2000 compare to a properly functioning Wideband O2 during AFR during Open Loop fuel tuning? Is it so far o...

The Low and High fuel tables are dependent on which camshaft profile is currently active. And guess what dictates that... Yeah, it's VTEC...

To get exhaust pops/burbles, you have to keep the fuel on and retard timing for a short while after lifting throttle. That's basically what the Jaguar engineers do on their F-Type. https://www.youtube.com/watch?v=WsUsno-Mv2E While the ability to leave fuel on for a while after throttle lift is defin...

I'm looking at 2:18 in your v13 datalog and I see the issue you're talking about at 4900RPM. All modern ECUs will reduce injector pulsewidth to account for the Evaporative Emissions Charcoal Canister Purge Valve activating. So in anticipation of additional fuel vapor, the ECU will reduce IPW to try ...

To confirm, 'Knock Sensitivity' has no effect on the calculation of Knock Control or Knock Counts. The help file is wrong. There are no currently defined tables that govern how to tune what the ECU thinks is Knock. 'Knock Sensitivity' may modify the multiplication of 'Knock Control' and 'Knock Retar...

Try adjusting the small hex screw at the throttle body. You may need to increase or decrease minimum plate angle.

The real issue is the increased mechanical noise from the engine. Increase the knock sensitivity tables where you see the knock control increasing until the knock control stays around 60%. The problem I see is that you are getting knock readings at low load and 3600 rpm, where the knock sensitivity...

An ability to 'merge' several datalogs into one. So I can capture short logs at various RPM/Load of only relevant stuff, or during short opportunities while driving. This can let us focus on problem areas with a large cumulative sample size. A way to 'save all' datalogs (from FlashPro) instead of ha...

Hello, I'm running version 2.9.5.0 right now for my 2006 Civic SI. While there have been no changelog updates for the vehicle, every version released says the firmware on the flashpro module is updated. Does the firmware update only include the changes indicated in the changelog, or are there "unde...

Flex Fuel!!!

Xmas came early this year! :)

Ok, we need to add the sensors for the next release.

Will you please do the same for the S2000 ECU?

If all you want to do is disable the effect on ignition timing due to knock detection, set the Knock Retard table(s) to 0. This will effectively ignore the Knock Control % and the other two, MBT and Ignition Limit tables will still operate as intended.
