What Is map tracing?

**HLxDrummer** · 03-07-2011, 11:58 AM

Map tracing is a feature in the software. When it is turned on, it will highlight the cells in the various maps that you are currently in and, if you chose, the cells that you were previously in. For example, at idle it will highlight the cell that corresponds to the RPM and load you are at. This is nice if you want to adjust your idle AFR, for example. No guessing which cell you are in, it simply shows you.

Since my car is stock injector still, I use the map trace the most when WOT tuning. I hit reset (so no cells are highlighted), do a pull, and coast to a safe parking place. All of the cells I was in during the pull are highlighted so I look at my logger and if at 6,000 RPM my wideband was lean, I go to 6,000 RPM on the EMU and it shows me what load cell I was in. Theoretically this shouldn't be an issue as it should be a set boost the whole pull, but as you can guess it is hard to get boost dead on throughout a pull.

This feature is not really needed if you are tuning based on TPS like with an SAFC since you can read the TPS values and RPM values to find your cell. And obviously WOT would be the highest throttle reading..

Nice review.

Are all of you still using the MAF?

**HLxDrummer** · 03-07-2011, 03:15 PM

I'm still on the stock MAF but if Forest has good luck switching over I may as well. Your off of it right? Weren't you having some issues?

It was also difficult to "calibrate" the TPS. With the Ultimate, I can wire everything normally and tune based on TPS OR MAP. Of course I am using MAP, but I still have the TPS wired in for things like the two step.

I'm pretty sure the blue can adjust fuel via MAP as well. I don't have it in front of me but I'm 99% positive one of my blue fuel maps is pressure in kPa vs. RPM. I use the greddy map sensor and the injector harness, so I don't know if that makes a difference.

Yeah, tip-in has become a bitch but I'm not using a Hz Map built off my setup, I'm using Grayson's map.

Using both Throttle vs RPM and MAP vs RPM has greatly helped though. I haven't finished tuning this way yet.

I run a ported MAS with the Mellon bypass mod (filter under the bubble). The AFR`s are so repeatable with that setup I`m loathe to ditch it for true SD. For me the gains wouldn`t outweigh the drawbacks.

You can`t adjust the main Karman Airflow map in the Blue with the Greddy Pressure Sensor, that load option is not available for that map.
