Sorry for the long post

I have my emanage setup and have not adjusted any map yet,

Rotary Switches settings
First 3 from the left are 4 - 8 - C. On the parameters settings, it is recognizing the engine F20C.
Adjusted the next 5 A.V.V rotary switches to show value% -0 on the main unit window
Fully turned counter clockwise the last two rotary switches (VPV and VAAV)


I started off with opening a new file, having all the "map selection" unticked and exported data to emanage. Started my first run and I noticed that VTEC is kicking too early around 5000rpm and loosing power. logging my A/F with a wideband i plotted a chart. 5100rpm to 6000rpm the A/F is scaling up (lean) and drops just after 6000rpm.




I changed the RPM values of the A.A.V to 200rpm - 300rpm - 400rpm - 500rpm - 600rpm - 700rpm. This way, they will not interfere with the rpm range. I ticked the VTEC setting in the map selection and changed the VTEC to VTEC HI->LO and VTEC LO->HI to 6000rpm.
Result:
getting a spike (lean) between 5900 and 6100rpm and it can be felt during acceleration.



Comparison between the two. from the looks of this i am running richer across the rev range on the graph red



Is there a reason why i have to adjust the vtec point, i was under the impression that if i had no map ticked it should take the factory ECU values. Also is there a way how can I adjust the spike ?

I want to come with a blank emanage file and upload it and car will behave as factory settings. Is this possible with the emanage ??

This thing is driving me nuts and i haven't yet started

My car is still bone stock.

Thanks for reading
any help appreciated
