how to sd my car Hi. I want to make my car and tune it with speed density. How do I do it? What parts I need? Currently I have slp lid, stock maf ported and 90mm ls6 intake modified by TPIS. The intake does not have the hole where I see you guys put the sd sensor in the Front. Any help please.
There's no "SD" sensor. You just unplug the MAF (or remove it completely) and boom you're in speed density.
Although at this point, given your expertise level in tuning (or lackthereof) you're better off taking it to an actual tuner to do this. It's not as simple as unplugging the MAF, you also have to tune some things in order for it to run in this new mode.

Speed Density is based on a MAP sensor (Manifold Air Pressure) which you already have. The LS1 with a MAF uses both systems to calculate airflow. You need to fail the MAF correctly to get to SD mode. Do a search, there are plenty of articles that tell you how to fail the MAF and then how to tune the VE tables. You are best to use a wideband O2 but you can use the fuel trims to tune.

We have a speed density faq/open thread in the PCM Diagnostics & Tuning section: https://ls1tech.com/forums/pcm-diagn...uning-faq.html
You'll get better answers over there AND this is the INTERNAL ENGINE section. You know, pistons, rods, bearings....
