I finally hooked a computer up to my hondata box to see what would happen, I was curious about my injector's duty cycle and how much breathing room I have...the digital dash on the computer is pretty cool, if distracting.

But I was kinda expecting the ignition timing values to be a bit lower (like twenty something) Does it seem high? It's a stock H22.

Screenshot from a high rpm/high load part of the drive.

 

One bump for an answer...

 

36 deg of timing at wide open throttle...
Yes that is too much timing at wide open throttle for most h22 applications.

 

yeah thats alot of timing is your car tuned

 

Dyno tuned for a different bolt-on H22.

May or may not be appropriate for my engine, either way...from my (very) limited amount of EFI knowledge I thought typical timing values for the high end of the RPM range were in the twenties, and that ignition timing was usually backed off as RPMs went up (this tune is pushing from the high twenties to the thirties as RPMs pass through 5000)

 

That may not be the actual advance, depending on how you have things set up. The easy thing would be to pull out a timing light and compare it to the computer screen with the engine idling.

 

Hey, if theres no knockn keep walkn.. Advance will make the car dance
