Tuning for Mild Cam, Headers, etc....

Oh I done that before I first wrote you, I thought you was wondering what all I tried.

I used the jet 2 for this if that was the best thing to do. I set the desired idle speed on 850 and the spark table on 22. Did you want the whole table at 22 or just around idle cause I set it there at about idle? At a point it idled up to a part of the SA table i didnt move that was about 26 degrees.

Heres the log I believe the way you wanted. I had to drive alittle to get into closed loop. It has a 180 degree thermostat also.

At idle Closed Loop the BLM is 108, that is as far as BLM will go to take away fuel. VE has to much fuel at idle.

Look in the XDF, use categories and find the hacks, apply the BPW and Spark Advance hack, NOT TPS, and you can see Spark Advance and fueling in data stream.

The first one may be alittle better. I had a good chance to make 2 so I did. Im not sure if its best to do this after its warmed up or both.

[EagleMark]

Logs and tuning adjustments should always be done warmed up.

Logs don't show near enough spark for that engine.

Also IAC counts are very high at idle, turn the screw in a 1/4 turn to open blades a little, with key off. This allows fuel and air to mix better.

My IAC dont have a adjuster if thats what you meant, I have noticed before they were high. Theres a screw for the blades that adjusts the idle but then it will be idling way over 850 I think. I checked the IAC and cleaned it. Heres the results after, idles at desired idle speed even in closed loop until drove then it sits around 1500 RPM.

I believe he meant to adjust the idle on the tbi on the throttle linkage side. with the torx screw.

[Davis_1377]

Yea thats what I was gonna do but I take that back, Theres nothing to adjust there. Ive seen these throttle bodys have that idle screw but this one has nothing but a shiny spot there with no place for a screw.

Awl or small screw driver, hammer, punch hole, pry shiny spot off and you'll see torx screw.

IAC controls Idle speed by adding air, not throttle blades.

I'm not sure how looking at same logs over and over is going to help? I've told you three things you need to do for idle and no change? Spark is same, Fuel is same, IAC count is same... if we ever get passed this there's another 100 things to do.

It's been so long I forget if you have enough fuel to start? What injectors? What fuel pressure? What's estimated HP of engine?
