K20a2 with Rotrex - Kpro
Posted: Sat Mar 13, 2021 11:18 am
Hello,
i have a Lotus with a Honda K20a with Rotrex compressor, RC 750cc injector, 3bar Fuel pressure and Hondata Kpro.
Last year I ve started to have some problem like misfire at 3500 - 4000 rpm, and after 6000 it s seem to work not as well as it should be.
So, I make some work on the car:
- New spark plug NKG BKR8EIX
- New coil pack
- New acuity TPS
- New Map Sensor ( a Bosh... it was like that when I bought the car )
- and check a lot of thinks
After that the car seems to work fine, bus last week i had the same misfire problem.. I open the cam cover to check the timing chain and other things, all is OK.
I know that the calibration was made when the car have a water /meth injection, and after this installation was delete, and the calibration unchanged.
So I have several questions:
- could you confirm me that the RC 750cc dead time are ok in my calibration:
Voltage 6,07 8,09 10,01 14,06 16,08
Deat time 2,55 1,70 1,27 0,84 0,71
- as the MAP is a custom one, I can 't be sure of the voltage to pressure conversion..
You can find the .KAL and two logs, on the first the car doesn t have misfire, on the second the car have misfire
Thanks for your help
