Title: KRKTE CORECT DEFINITION Post by: chiptuner123 on May 05, 2020, 06:41:20 AM I use injectors 625cc Bosch,I set the KRKTE,I start the car and I see that ,at full load the AFR is 13.00 I set again the KRKTE so at full load is 11.50 so,at the idle is abaud 13.00 -14.00 at part load are 12.5-14,5 and long term fuel is -14%. sort term fuel trim is 0.0% and only at part load fluctuates to +% -%
**Cold start warm up Correct. You think I must ride the car many klm to adapt? I leave TVUB stock Any opinion ??

If you didn't already know what KRKTE/TVUB should be based on datasheet, which you clearly don't if you didn't touch TVUB.

Title: Re: KRKTE CORECT DEFINITION Post by: sda2 on May 06, 2020, 11:33:11 PM Hello,
Some time ago I collected data of several 20VT injectors from their OEM calibrations. The 0 280 158 123 were read from 997tt binary with matching A2L. Edit: Keep in mind, that Porsche has a 3.8 bar fuel pressure regulator, so you want to use either the same pressure or fine tune those values.

But you could look for injector data in standalone ECU software. EMU black comes with a lot of sensor, throttlebody and fuel injector data :) Title: Re: KRKTE CORECT DEFINITION Post by: chiptuner123 on May 10, 2020, 12:52:18 AM Thanks for yours help :)
