I've been contemplating a 'different' design of an LT1 intake, but the way it would be situated, it would be near impossible to run a MAF. Kinda like a ITB setup.
Why? Because I don't like the sharp 90deg angle at the throttle body. And I could most likely get more flow..

SO, can someone give a 'quick' comparative between MAF and Speed density fuel injection.
I bought the book some time ago on GM fuel injection, but changed my mind a couple of times, so it didn't get read that much. And what I did read has been forgotten.

Thanks E

 

The 94+ LT1 pcm can handle speed density mode just fine. The tuner I have been using the last few years prefers speed density so for me the MAF is just basically a coupler.
I began running the y-pipe setup because there was only room for a very short filter inline and the inverted cone in the end of that filter made for screwy MAF readings back when I was using the MAF. Airflow needs to be even and smooth when it crosses the MAF or it can be erratic.

 

PM'd ya..

So give me a quick over view of what yer talking about..?

You know, for reference of course.

Hey, you wouldnt' mind giving me your tuners info would ya?
The guy that I was going to use doesn't like Speed density..

Was there something else about my setup you were wondering about?

 

Nothing wrong with running speed-density, with a very good tune. The VE tables are critical.

VE= Volumetric efficiency right?

Correct.
