Title: Timing help from some experts? (log diagnosis needed) Post by: MmmBoost on November 21, 2011, 07:46:49 PM Gentlemen,
It's been a while since I've actually hooked the laptop up to my car and tried to squeaze a little more out of my car, but just recently I had caught the bug again and found some free time. Vehicle Specs: 2005 Audi A4 Stock displacement AMB 1.8T (some internal upgrades though) Injector Dynamics ID725 Bosch 005 fuel pump Bosch F5DPOR plugs MKVI TFSI Coil packs ME7.5 running Maestro 7 (this is where the shit hits the fan with diagnosing the issue) Boost Level on these pulls was 26 PSI using an EBC Every since I have been running this software on my car, I have always seemed to have problems running a decent level of timing on higher boost levels. Now I understand more boost = more load = less timing.......that's not the issue. It seems as though my timing just simply will not follow KFZW or KFZW2 once load gets to the 180+ range. Looking at my logs from this evening I keep getting massive timing pull right around the same area or boost/load and my timing drops like a rock. I don't believe this is knock related or else I would see boost duty drop and my Specified Load drop down to levels specified in my LDRXNZK map. Could you guys please have a look at this log and tell me what you think. I have every reason to believe I am hitting a limit specified in the ECU somewhere. It almost seems like it's trying to cap load at a very familiar number of 191 which tends to be the last value in many maps. Does this look like Torque Monitoring/Control intervening? https://docs.google.com/spreadsheet/ccc?key=0Aoetxfc9e1KpdDJXQzB3dVRQUU9TbkZsX3QwUS1Jd3c (https://docs.google.com/spreadsheet/ccc?key=0Aoetxfc9e1KpdDJXQzB3dVRQUU9TbkZsX3QwUS1Jd3c) There are the maps that I have been staring at for the past few days trying to see if I'm doing something wrong.

It takes quite a bit before you get load intervention. Title: Re: Timing help from some experts? (log diagnosis needed) Post by: RaraK on November 23, 2011, 06:26:00 AM i had a 2871 on my 1.8t and i ran slighlty less timing than that at higher load, 1 value less roughly, and i would see cf's of 3-5. I think you just need to lower the higher load timing a little bit and go from there.
figured it was a similar setup so.... btw i did have a fmic as well i dont know what your full hardware specs are. we dont get too hot here in PA either, 90 tops. so i never had it in a situation where things where fully heated up and a situation where the timing would have been at its worse conditions.

I am running a FMIC. It's not the largest core in the world, but it does a decent job. So you're basically saying timing looks about right then? Even with IATs below freezing? Title: Re: Timing help from some experts? (log diagnosis needed) Post by: RaraK on November 23, 2011, 11:24:46 AM they are a little higher than id run, i like to see no more than CF's of 6, you are a littel over that, i would remove ~1.5 from your timing values, that should get you down around 4-6 CF.
