Unfortunately not having this spreadsheet for you but for starters you might want to check that PC_Link_VRFI.cfg and VRFI_Log.cfg configuration files contains correct lines for your setup. E.g. there is MAP3bar_True and SpeedDensity_True etc.

Optionally you might use lambda values instead of afr and so on. Not all can be adjusted from the software.

I had to start from the scratch because of E85. Therefore I commented ManualBaseInjPW_True because I had not any ready calculations available for the injector base pulse width.

 

Hallo Mukle! Thanks for your reply. I have alredy changed map3bar true,manual baseinj.pw true,speed density true,lamdacal true in the config. file. But when i try to save it,it's only apperes on the screen on the computer " if any changes were made to the softwere configuration file you must restart the program to load your changes " I don't know how and what program i have to restart.

 

Those config files are for the vrfi software. PC link VRFI for tuning and VRFI log for logging from the current suite. If those programs were already open you need to re-open them to load your changes after saving config files.

 

Ok,Thanks.I try to do that tomorrow.😁

 

Those config files are in plain text format and can be edited manually by editor.

 

👍

 

Maybe it will be useful, don't forget to rename it from .txt to .xls. Fuel_Injector_Calculator_My_Motor_Revised 1.xls is a file from someone on this forum

 

Thanks for sharing these.

 

Assuming that you have installed the vrfi software you just close the program and click the icon to start the program again. I think that this is just remainder that configuration changes take place after program restart. If the changes were done while they were already open.

There is no special procedure to restart the program if you mean that.

 

Mukle! Thanks again for your help. 😊👍

 

Actually you do not find them in the software directly. You use spread sheet calculator to find the initial value of the base injector pulsewidth which you put in the software and where the tune is based of. Other spread sheet calculated values are for your own purpose to see that injectors and fuel pump delivery is in the reasonable range that you are planning to take power out. You might have to use some best practice values there because they are not explicitly found.

If not already done it is wise to read vrfi installation manual properly. There is some good information how the system is designed and intended to use. Even there is 300kPa software available for vrfi it was not originally designed for the FI applications. However there is not plenty of good alternatives left either.

 

Hallo Mukle! Yes,i have 300kpa speed-density firmware technote and installation & tuning manual. I made the engine starting procedure and viewed and logged realtime data after engine start.It run to lean. Blm was to high (125) so i added some more fuel and uploaded that to the unit. I do a teststart tomorrow,hopefully the bike runs better,if not pherhaps i have to add some moore fuel./Kari

 

Yes it appears that it is maxing out the BLM's and running very lean. Initial value for the bpw may be too low. I would try to increase that and get into BLM's 90-110 range before starting updating ve-table. BLM window can be adjusted from the software parameters.

Now it is easy to understand why absolute VE-values will not present the real world because bpw is adjusted by manually. VE-table values level will follow that bpw while maintaining the targeted afr. I mean that there is no need to be alarmed if VE-values seems to be low even there is turbo. Their relative values are more relevant here.
