k24/k20 turbo base tune FIX HELP

[CalibratEd]

i took 30% away from the whole chart should i try to start it again?

Yes try and restart it. Reduce fuel until the afr is close to 14.7 at idle.

I did the 30% and now the a/f is around 9.2-10 do you want the datalog and tune to what I did?

That’s good. That means you’re on the right track. Remove 30% more. Keep in mind this changes should be applied to all the fuel tables not just vtc 0.

It idles low low if I take more fuel out you think it will still start?

[CalibratEd]

Does the car have an IACV? If not it could be you need to adjust the idle screw.

They car should idle better as it should be leaning out at idle.

IACV delete plate. And it’s running 9.4-9.8 on air to fuel is that not lean? I’ve let it run for 1-2min

No that is not lean. That is still very rich. At idle it should be around 14.7. I would increase the idle with the idle screw and reduce the fuel by 30% more.

Make sure to re-calibrate the TPS after you adjust the idle screw.

this is the base tune and datalog that runs the best ill take another 30% and adjust the idle screw.

this is after taking another 30% and fixing the idle screw

Looks like its idling way better. The rpm is fluctuating a little to much but its better than it idling very low. Make sure you let the car reach operating temperature before you make the fuel adjustments.

i keep getting a po0335 error code what could be causing that? and could that be the reason of the rpm fluttering? im out of gas right now ill have to get more gas and let it warm of and get a datalog for you

Yes, The code could be the reason it’s running rough. I would fix any codes before continuing to adjust the calibration.

Hey man question I had my base tune running good but then realized air was being sucked into evap, forgot to block it after I got the block plate it won’t start now. Any reason why?

[CalibratEd]

It’s no longer working as you tuned around a mechanical issue. Now that the issue is fixed the tables are off since the tables were adjusted to compensate for that issues. Log the car and see if fuel needs to be adjusted.
