ECMlink Need Help Setting up Speed Density (Car won't start)

[StrokerMax]

Hello,

I'm having problems with setting up speed density with my car. I bought the plug and play setup to make it as easy as possible.

But for some reason my car won't start. I can plug back in my stock MAF and change settings in ECMLink and it fires right up.

I attached a log. Hoping someone can please take a look and point out any wrong settings.

I bought the SD Bundle (GM-style MAP, IAT, pigtails and bung) http://www.ecmtuning.com/product_info.php?cPath=28&products_id=50

I ran the bung for my IAT in my throttle body intake elbow and just a vacuum line off my manifold for the 4 bar MAP. Then plugged the adapter right into my stock MAF plug. Is there something I'm missing?

By the way I have a Magnus intake manifold.

Thank you

I think I assigned the pins right. and I changed my Base Maf to speed density..

Try changing it from MDP to Baro like this. I think that may be your problem.

That was it!!!! Thanks Logan!!

You're welcome! Good luck with the car

PS- I only knew that because I fired mine off for the first time last night, and had to go through the same settings. HAHA

HAHA. Glad you were here to help. I'm excited to start dialing in my car on speed density. It was way overdue.

Once you go speed density you will never go back!

You're not kidding EvilGST. My car ran like crap with the stock MAF. I didn't know how bad it was until driving it with speed density. My car is way better.

Care to explain? I'm going SD as soon as I get my stuff straight.

When I ran the stock MAF I had all kinds of issues. My car had very rough idle (Lots of rattles inside the car). I initially though it was from having stiff motor mounts, cams, Ect... With speed density my idle has smoothed out and my dash no longer rattles.

I had an issue with jerky throttle at low speeds. It was almost impossible for me to cruise in a parking lot in 1st gear because my car would start bucking. With speed density this is no longer a problem.

Best of all is how much better my tuning seems (and I haven't even gotten into advanced tuning). I used to have issues with running too rich (and struggled to adjust my fuel correctly). My car would smell rich like E85 fumes inside. Thats cleared up as well.

I would say that speed density has made my high modified Eclipse GSX feel more like stock in terms of drive-ability and smoothness. Yet you floor it and get the power of a 500+ horse power car.

I also love the idea of being able to blow an intercooler pipe off and being able to dive home.
