Need help identifying this electronic module.

ckh, welcome to the TDR. We hope you stick around. If you do, please fill out a signature so we know what you have (reference) and possibly where you're from or other interests.

Will do. My father referred me here, he's been a member for a while and subscribes to the TDR. I will have a lot of questions as I progress with modifying my truck in the future.

"Soot" is "burned" excess fuel. "Unburned fuel" is white smoke.

Complete fuel use has exhaust of only CO2 and water vapor (H2O). It is a hydro carbon fuel reaction with Oxygen. Oxygen with carbon = CO2. Oxygen with Hydrogen = H20. Soot is carbon that did not react with Oxygen, this is why EGR causes more soot.. but too much Oxygen, and we have NOx, that is a reaction of the Nitrogen in the air, 78% of air and excess oxygen in the combustion chamber at high temp/pressure. NOx doesn't hurt power or economy, but it's what makes smog and EPA and CARB are very interested in smog.

In less scientific terms, carbon means it was burned, it just wasn't burned completely. "Unburned fuel" is technically not the correct term. I'm pretty sure we can agree that soot means there was excessive fuel regardless of the term used.

Yes, incomplete combustion might be the best way to describe it.
