Did you set the Dead time for the injectors?

You first need to know the dead time of the injectors you are using as a starting point, from there you can adjust these dead with the aid of a
wideband by adding electrical load (fan, blower,headlights, etc.). The aim is to have the correct AFR at the various voltages (10v - 15v).
Parameter > Fuel Trim > Injector Voltage Compensation is where you will see the table.

ok so i got it to idle with the dead times and i have pretty good wideband readings around 14.5:1.
Now the issue I'm having is that when i attempt to drive the car or rev it goes super rich in the 10's and bogs and can barely drive the car.
What steps do i take now. i tried adj overall fuel trim but doesn't help.

Make sure hondata and engine timing are sync by using a timing light and locking the timing with online > set timing. With that DONE and timing unlock you can drive the car and correct the AFR

ok so now do i adj the individual cells? thats what I've been doing and was able to correct the afr.
now when i try to go into boost its almost like it won't let me and it backs off. timing on the light and s300 seem to be pretty well matched. although i did take notice when i snap the throttle id see ign. go to -4 is that normal?


thanks for your help.
I'm slowly getting the hang on it. lol

Post your current calibration and a datalog so we can figure out what's going on
