Weird Start Up with tune

[NorthShoreChiMM]

Hey everybody,
Whenever I install the tune I get this weird startup like the car is almost hesitating at 500 rpm then shoots up to 1500 like normal, like a sluggish start. This only happens on startup with mo's tune. Every other aspect of the tune is fantastic, I love the firm shifts, it really wakes up the car. There is no other problem with the tune, this problem is only on startup. I talked to martyo way back and he said it could possible be a vacuum leak. With the stock tune on it doesn't hesitate and starts up strong as ever. What could be possible causing this. I will add a video of the start up below. Thanks for the input and knowledge.

PS. that squeak is somewhere in the heating system, apparently lots of marauders have it, vents opening?

Uh....asking Marty aka: "MO" is the BEST way to get an answer and get it fixed!!:beer:

I couldn't get your video to work. My start up RPM's dropped dramatically also with the new MO's tune but I had no hesitations or any problems. Just didn't rev as high and slowly drop as it used to on start up before tune.

sounds like a possible vacuum leak or the idle control switch. I'd check vacuum lines first

Congratulations.......I think this is the 100,000th thread. :trophy1:

The rapid rev on start up was something ford put in to make the car sound cool. We take it out but if you want it back, let me know. I hate revinh a car when the oil is at the bottom of the engine and not at the top end.

Video won’t play.

Did you ever check for vacuum leaks or do any other debugging on the car?

Contact me again.

I don't have a problem with it. Just the first thing I noticed when I installed it. The OP might may feel differently.

The lower rev is not my problem, the problem is the hesitation that hangs around 500 rpm for a second then shoots up to 12-1300. I will send video to you MO. I have not done a vacuum leak check.

Clean your IAC first. It's not in the tuning.

He sent me the video by text.

Unless I’m missing something, there are no issues.

Cleaning the IAC would not be a bad idea any way.

My car sounds like a war when it starts. Bystanders have honestly ducked and I think Chuck Norris actually cried. But no complaints on the idle.

Issue is hopefully fixed for now, MO gladly helped out, and I greatly appreciate it. Great guy. Will update in the morning. Thanks

I also hate revving a car when most of the oil is down low.

Great customer service as always, Marty.

FOMG!

I laughed myself into a coupling spasm... And then hacked up 1/2 a lung...
"Chuck Norris actually cried."

DAYUM that is funny. I wish I'd thought of that line.

Dude, hats off to you!
