Project Black Golfball-plans for 2010 Options

Finally got back to working on the Talon Sat.

After I put in the replacement trans, I developed a leak and parked the car again due to the weather. I thought it was the transfer case seal so I pulled it out. Transfer Case was full of oil, so that wasn't it.

The inside on the trans housing was all wet when I pulled the clutch fork boot off so apparently one of the trans seals is leaking. Looks like the output shaft for the transfer case may be the culprit. It seems to be seaping just sitting in the driveway. Thing is, why would it be wet up by the clutch fork?? The input shaft seal shouldn't be leaking that much because it's above the oil line in the trans, at least I think so. I hope it's not the input shaft seal, I'd have to disaasemble the trans to replace that.

I did remove the inoperable cruise control since I picked up a no-cruise cable over the winter. Need to finish hooking that stuff up.

Please don't take this wrong, I am generally in support of MAF, but am open to SD where the circumstances better fit an SD setup.

That being said, any *good* MAF manufacturer will be able to give you the MAF curve to plug in to your tuning software. Then yes you have to datalog and tune your MAF curve for your specific setup, but if you do so you'll have much more accurate AFR through the entire RPM range. Vacuum estimates airflow, a MAF will always tell you nearly exactly how much air is going in, if you have it calibrated properly.

In the mustang world, damn near EVERYONE ditches SD to run MAF if possible. It does take more tuning and datalogging to get it dialed in, but general consensus is that it's more accurate, so worthwhile. I do understand that MAP/SD is a lot easier to setup and configure though.


I guess I just don't see why you'd have to use the stock MAF to calibrate it, if you have both a good MAF and good tuning software, not dealing with any of that MAF translator bullshit.

If you'd like, i can get some screenshots of the tuning software I used on my Mustang to show you what I mean. The author also built an analyzer program, so you basically plug in your datalog, and it gives you the updated MAF curve to plug back into your tune. Rinse and Repeat. I believe I could make my analyzer program work with any datalog from any logging software, so long as it has the required parameters.

The way I see it, MAF is best on NA cars but SD is a better way to go about things on a turbo car. If you have a 3" GM MAF and 2.5" intercooler piping, your calibration will be different that someone with full 3" since it would change the velocity of the air going through the MAF.

Both are great ways to go about things. Idle quality and throttle response on SD can't be beaten. But again, opinions are like assholes, and everyone's but yours stinks!
