We have a VVT thread, Boost thread and others so i thought i would start one for people to post thier timing tables in to help others with milage, E85, or idle issuse that seem to be becoming more common. IF YOU USE THESE TABLES BE SURE TO LOG THE CAR FOR KR!! Every car is different and will take things differently.
If your having issues with a rough idle when turning on the AC or just plain idle read this. There are many major factors that go into getting a smooth idle. Timing, Airflow, cam timing, and fuel trims. Load also plays a huge roll. Your aiming for a 1.00 Lambda at idle. You need to have a smooth idle area in your tune as far as timing goes other wise timing will become erratic and give you a fluctuating load. In the scanner 0*-5* is normal as far as advance, when it goes beyond this you car hear the car surge or miss.
You basically want to start with your Maf correction table, Highlight the cells between 800-1000rpms and from 20% to 40% load. You can start with a average of those cells or just set them to 1.00. Next use the same idea on your timing table trying to correlate those same cells by adding or subtracting a couple degrees to make those cells as close as possible DONT PUT IN 1.0!!!. Be sure your cam timing area is stock aswell or set up for cat warm up disable. Next start the car, make sure its warmed up and STFTs have been recording for a minute or so then restart the logger "important other wise you will come up with a crazy STFT at idle". let the car idle for about 3-4minutes then turn on the AC and go for another 3-4 minutes. This will create a higher load and jump to different cells in all those tables you smoothed. Copy and paste special by % those cells into Maf correction. The fuel trims in the histo cells you use for no AC should be very close to the cells where you have the AC on. 20-30% load should be AC off and 30 to 40% load should be AC on. Repeat the logging process a couple times and check after each flash to be sure your two idle areas are not getting too far apart in value.
Quick way to do this if your car idles good with AC off but bad with AC on is to make the 20%load to 40%load idle area all the same in timing and Maf correction.
This whole problem should be avoided if you tune the car correctly but sometimes these few cells seem to stray out there with out people knowing.
Here is the timing table i use on my car to run full E85. I average 28-30mpg actual pen and paper tested. If you look at it you will see that I made a Hump for cruize just like the cam section. This may or may not be a good idea but my car loves it and shows NO random kr with this table. I have seen .7* a couple times coming off a light but its only on cylinder 4 "stg4 clutch chatter" It is also rolls timing in smooth when rolling into the throttle on a pull. Let me know what yall think about it, there is a funny story behind the idea to add the hump.
