Logger help

[SuperDave007]

I'm pretty new to this logger stuff so I just started messing with tuning and did some logs today. Most was 1st and 2nd gear. I did not have enough space today. I'm just trying to get the basics down now. Any help or info on were to change what would be great and would give me a good starting point. Thanks in advance.

95 Talon TSI AWD, 660s, S-AFCII, turbo back, no cat, 255 walbro, ported big 16g, bottom honeycomb out. HKS SS(venting till kit comes in),FMIC, upper & low piping, ZT-2 windband, stock manifold, I know there is a little more I'm forgetting.

I know this is a little late to reply, but I just noticed your thread didn't have any replies. I would start by putting the honeycomb back in the MAS. I looked at your log and can't see very much useable information in there. Have you set your FT's yet? What do you have your TPS trigger points set at? They should be at 30% and 80%.

After you get the FT's set and put the honeycombs back in, set your SAFC Hi Throttle map to -25% across all Ne Points and make a 3rd gear pull. You want to log timing, O2, airflow and TPS for the first log. Once we make sure your TPS is functioning properly we can drop that from the log.

I missed this one too. I'm still pretty new to logging myself but here's what I like to do with a log like that for setting base, idle and mid.

Export the data to excel and average the fuel trims. Sort by load and put it in a graph. Looks to me like your idle is a bit lean and the mid is pretty rich.

I would be careful about not running a cat in Cali, thats a minimun $2500 federal fine if a cop pulls you over and checks everything out.

Also, do you not have an AFPR? It would probably make a world of difference to help control that 255 pump of yours. At least think about it.......

Like Spyder said, You need to do a third gear pull from around 2500 rpms to redline, first and second gear are too inconsistent and don't put enough load on the car to achieve tuneable results.....

You want to monitor your o2, timing, and rpm's, and you even have a better advantage being able to use the wideband as another reference. After you log, go back and review your results. You want to tune your o2 volts to as close to .92 volts as possible without knock. Using your wideband, you should see between 10.5:1 and 11.0:1 A/F ratio. Although 2g's don't log knock, it can been seen through the timing advance numbers. When you go WOT at 2500rpm, your timing will drop to around 5 degrees and should steadily climb up to redline to the area of about 19-21 degrees. If the timing drops or holds at any rpm points, that is a sign of knock and you need to richen things up on the AFC, or turn down the boost if your too lean (under .91 o2 volts)
