Hi,
I have installed new injectors. Im going from BOSCH EV14 630cc to BOSCH EV14 1000cc.
I know that i have to recalculate my KRKTE but then im stumbling in darkness.
My plan was first to recalculate my KRKTE and flash the ECU, Drive couple of miles and watch fueltrims and adjust accordinly.
I have also zeroed my KFKHFM without knowing what i do
Is there any more "Tips n Trix" and is there a good calculator for calculating KRKTE?
Well first off you need the TVUB and KRKTE,
TVUB is the battery voltage offset injection time and this can be found on the internet or speak to the injector supplier.
KRKTE can be worked out and if you have a look on here you will find the formula but a good starting point is 34/injector cc so you will start up at around 0.034. You should be at around 0.058 on the 630cc
If you have wideband then you can as you log the trims and see whether it needs adjusting. The ecu can trim +/- 25% before MIL shows.
Temin/Teminva are the minimum injector in time
Fkkvs is the fuel system correction and there is a utility on here that can help you with that
Other than that I would really suggest you have a read of S4 Wiki and get to grips with it first before pissing in the wind. Las thing you want is to do it all wrong and bore wash the cylinders and screw the engine before you've even got going!
