'05 PND ECU, K24/K20 IHE base code

Given the current life situation, it's gonna be quite some time before I can get the EMS fine-tuned by a tuner.

I'm driving the car when I can to get everything settled. Runs very well once up to operating temp. The problem is that during warm up throttle tip-in & part throttle response is very jerky.

I'm trying to figure out which parameters it would behoove me to adjust to resolve the warm up drivability.

Fuel cut? Does TPS value = % of throttle angle?



ECT ign? for this & fuel I can't figure out what Corr value represents


ECT fuel?

TPS is percentage.

Ignition is degrees.

Fuel is percentage.

Thank you for responding.

SInce my issues seems primarily to revolve around low load / lower rpm trailing and tip in (driving on local streets, on/off the throttle in small degrees)

I'm thinking I should look at the fuel cut first.



The preset values are based on a 'normal' idle baseline? I'm trying to judge what would make sense in terms of adjustment. My idle is around 1050-1100. With the 80mm K-Tuned TB, I just can't seem to get it lower than that.

So, the question is, should all 4 tables in the first column be adjusted equally/proportionately?

I can understand the MAP based cut & recover have a 400-350 rpm window, so I assume that needs to be maintained when raising the minimum.

Should I just revise the TPS vs Min RPM & Fuel Cut Delay? Start with about 1000rpm over base idle?

I'm puzzled that the Max Throttle for Cut value = 5(%) - when the TPS vs Min RPM values are 3.3 & 8 (?)

Thanks for any input

EDIT:

I did forget to post this table: Can you tell me what the fueling values represent?

Those are raw fuel values in your photo.

What does that mean in terms of adjustment - I can't find an explanation in the help...

Raw fuel, like the fuel maps.

OK, I'll compare with those to see if I can figure that out then.

Can you speak to my other questions regarding fuel cut preset values?

We don't offer tuning advice.

I understand that.

I'm just asking if you can explain the relationships of the preset values so I can make informed decisions. None of that is in the software help.

I'll copy & paste all this over at K20a.org & see if anyone there uses your software.

The function of each of those is actually explained in the help
