Fuel cut at partial throttle only
Fuel cut at partial throttle only
Hi i recently deleted my iacv and used block off plate. I deleted iacv in ktuner software and also calibrated tps to 0.5. Ive adjust my idle screw to idle where i want it and also adjusted idle in software for 875rpm. I have re adjusted my tps sensor to 0.5/0.49 v at closed throttle. My problem is when im partial throttle and bring revs up once it hits 1875rpm it cuts out fuel is what i see in the live logging. Once i push the pedal more it continues up the rpm like normal. This happens in neutral and any gear at 1875rpm. This problem didnt exist before deleting the iacv, nor did i have any cel or any type of problems. Can you advise me what to check next thanks?

Yes, that's what the settings are set to do in fuel cut parameters.
Re: Fuel cut at partial throttle only
How do i go about changing this so it doesn't fuel cut at partial throttle? The fuel cut at partial throttle only happens at 1875rpm not any other rpm
Re: Fuel cut at partial throttle only
Alter the minimum throttle or rpm settings for fuel cut.
Re: Fuel cut at partial throttle only
What should i change it too? Do i put redline 8600 and 100% throttle?i tried putting both to 0 but car wont even start like that.

We have explanations for the settings in the online help. http://ktuner.com/KTunerHelp/fuel_cut_settings.htm
If you're not able to set up something that you like you should consult a tuner to fine tune the settings for you.

Re: Fuel cut at partial throttle only
Ok thank you but do you know why deleting the iacv would cause this?i have not touched any of the settings other that delete iacv and simply readjusting throttle stop screw and mechanically setting tps back to 0.5v closed.
Re: Fuel cut at partial throttle only
It didn't. You're meeting the thresholds for fuel cut, as outlined in those settings.

Problem Solved!
Lowered fuel cut tps vs min rpm .It was at 3.3 @1850rpm and 8@ 2300rpm. I changed it to 1 and 4 . Didnt change the rpm.
That was tricky cuz on all install videos or websites they never mentioned this but its probably because they used hondata since that doesnt have this feature i believe. All i seen was adjust tps sensor and calibrate thats it. I am using the Acuity tps on stock throtte body.

Glad you got it! There are a lot of settings to alter with this system which let you tailor it to your setup.
