 +**Post#396 - JBM - Aug 2007** - Spark advance for manifold pressure below 16 In/Hg\\ 
 +To me it's still a mystery why TC88A doesn't calibrate values below 16 in/hg. In HD's own Screamin' Eagle Ignition Race Tuner (SERT) you may customize the stock ignition module with SE ignition curves and calibrate map values in the range of 0-16 in/hg also. The SERT/OE range is 0-103 Kpa (0-30 in/hg), while the Twintec range is 54-103 Kpa (16-30 in/hg). SERT has 9 rows, and four of those are below the TC88A lowest row. I ran SERT before I installed TC88A.

 +This morning I sent an email to Chris Schroeder from Daytona Twin Tec and asked about those advance issues for manifold pressures below 16 In/Hg in TC88A. With his permission I publish his reply:\\ **Very few engines require additional spark advance below 16 in-Hg manifold pressure. The TC88A uses the 16 In-Hg value for all lower pressures. As further clarification, internal cylinder pressure is so low under these conditions (MAP below 16 in-Hg) that maximum spark advance values near 45 degrees are reasonable for most engine applications. Since 45 degrees is the maximum advance the TC88 series is capable of, there is no reason to complicate the advance tables. Even higher advance values yield little benefit.**
