4x1000 ID injectors
Hi guys,
My car is tuned with 4x1000 sard/denso injectors with resistor. Now, I went for another setup, got rid of the low impedance injectors and resistor and I replaced them with 4x1000 ID 's. If I change the lag times will I be OK or do I have to re tune the car? Do I need to change anything else in my PFC? Thanks! |
When ever changing injectors , no matter how well you do it with or without true lag tables;
you should retune for safety. If at your lowest boost of "X1" was tuned for "N1" AFR, for first tune with the new setup, add 5% fuel and log the AFR. From this it should be safe and hopefully richer. You can then know how the AFRs changed along with the new injectors plus the +5% fuel. Using this +/- change in AFR, you can then change the complete boost area if needed. |
Thanks for the reply!
Changed the lag times for both the primary and secondary injectors but as you said car has to be retuned.. As I am new to pfc, even though I searched and read a lot, a help from someone who knows is always better.. My injector map is all 14,0 while the base map has different values, do I alter both maps or just the base map? any other settings that I have to pay attention too? I have an xd 16 gauge inside and that would be my guide when tuning.. Thanks in advance, George |
Read again and now I know how the injectors map and base map work.. So silly question..
Can you help me out a bit with the other numbers in settings 5, if I tell you what numbers I have inserted for my setup? Thanks George |
I have set my front and rear primary as 0.55, the Q primary and secondary as 1015 and the dead times for primary and secondary as 2.600, 1.675, 1.240, 0.990, 0.805 Anything else I need to change?
