Gathering momentum

As expected I wasnt paying attention, I had placed the .cal files from the Custom OS's into the wrong place. Once they were in the right place a reflash of the tune worked fine. So Im now running OS3 with dual spark tables in SD mode. The software reads the cal files so that it can understand the PCM OS, I was running off the old ones still.

Efilive with custom additional features, like support for dual spark maps and forced induction.



After 2 passes at updating the VE table I am now hanging around -5 to +2, so Im almost there Im now making changes at 50% the recorded rate. One thing I noted was with the second flash and another 10 on average (max figure of 115 so far) added into the VE table things seem a little sluggish down low. Maybe things are a little rich at this point. Timing has remained unchanged, though I think I need to pull a little more timing out as there is a little knock retard at higher RPM. I guess I might even need some more timing down low the idle timing table is set to an 8 degree advance while redhardsupra's site recommends around 20. Though admitedly this appears aimed at people with cams.

Now is a good time to add some pictures to my boring text only blog, so here is the current state of the VE table.



I started reading up on the next step, which is idle and timing tuning. Idle is pretty good, though I need to make sure transition to and from idle is good as this might have something to do with the sluggishness Im feeling down low now. As usual the most excelent forum LS1tech.com has a thread to cover this topic as does my fellow blogger redhardsupra here. There is also an excellent link to what appears to be a foolproof method of recalibrating MAF's. Which I may do to allow extra data logging for tuning, though I expect to lose the MAF longer term.

My baseline tune was from an Auto and I suspect I may not have "cleaned" it out as much as I need to. The car drives fine, but Im still trying to figure out how to get the scanner and tuner to read it as a manual. Either Ill have to flash with a manual tune or will figure it out soon enough. Good old EFILIVE forums are very good for data gathering.
