Where is all my timing going??? Log attached

Very interesting..

Good to know Mick. I think Joecar and I have seen a number of SD 'MAF-Failed' tunes lately, that were still actually using MAF. And the MAF calibration was way off.

It is too bad we do not have a banner or indicator..that says MAF Failed. I fell victim to the same problem for a day or two. So, now when I test SD (CLSD) I usually make the Low-Octane Spark a degree different than High-Octane..log both CYLAIR and DYNCYLAIR and make it throw a DTC Code.

Mick, any ideas to help people insure they are actually SD. Like I said, we have seen quite a few lately... It is like we need an additional check.

Thanks..

The easiest way I can think of is to let MIL lamp go off. That way you will at least have had a visual indication on the dash that everything is set as planned.(once you have verified it once in this way you can then turn it off)

Good call..Should be the golden rule of SD tuning.

Thanks for the input..

I am happy to say that I went and did a log today and hit 12psi and it felt great. No popping or backfiring and it just pulled strong. I guess the plugs were the culprit all along. Here is a nice log I did and boy does it feel good.

On a side note I have a small A/C problem I'm fighting. When at a stop with the A/c off the car will idle fine, but when I press the a/c button it will flash for a few seconds and the idle will fluctuate up and down some and will then level out and the ac will work fine. I checked the freon and I even evac and recharged the system thinking it was a little low (it wasn't). When traveling down the road with the ac on it does fine and never flashes only when sitting still or coming back down to an idle. What tables need to be looked at? Also I had to do my V/E a little lean so that when the ac is on it is correct, but with the ac is off it wants to ask for 3-4% more fuel. It's like I can tune it for one or the other to get it correct (AC on had to add fuel) (AC off it runs fine but it is a little lean and is always asking for fuel when doing autoVE).
