Now that GM is selling the LS controller which includes the MAF (for their crate engines), I'm wondering how well the ECU can handle high airflow (ie: boost).

Even with a 1-bar map, as long as you're using a MAF, you're already close for the tune (some PE changes, spark, etc). But back in my S-Trim LT1 days I was always hitting the MAF limit on airflow.

I'm wondering if anyone's use this controller in a forced induction setup and what their experience was like.

Thanks,
Dave

 

LS controller as in the LS1?

It has pretty much the same limitation as the LT1.

Now, if you had an LS3... you had NO limits.
