I'm using Track Addict v3.4.4 and Race Render v3.5.5 and transferred a session that had OBDII data logged. This data is displayed when I play the video in Track Addict but not when I create the video...

Thanks, worked just fine.

Great app, downloaded it today and ran it at our local autocross club.

I'm wanting to export the runs to a video file and upload it. I've read the user's guide and under share I only have: Post...

Was doing some logging this morning as we are heading into hot season in SWFL. I recently reworked my spark table after doing plugs, wires, cap, rotor and then later multiple radiator flushes as it...

I know I'm digging up a six year old post but I wanted to chime back with an update and say that I still have the Astro, now with 145k on it and I'm still dragging that big trailer all over Florida. ...

Hello All, its been a while but I'm still tuning my AWD Astro and towing that big travel trailer all over.

We're moving into peak heat down here in SWFL so it is time to address the ping issues I...

Dirty MAF was an understatement. A while back I farmed out all my maintenance work to what I thought was a trusted mechanic who had a shop next to my office.

I'm doing all my own work again....

Thanks for the tip. I have checked the vac lines and they are good. The tight engine compartment likes to cook hoses. Filters have also been replaced. But I have not sprayed the MAF. I'll give that...

Hello,

We're moving into the wonderful FL summers again and all of a sudden the Astro Van has changed behavior.

I'm running the same tune that I created in last summer's heat. The van is in...

One last comment/question. How much lag time should exist between a shift and TC lockup? Ideally I think I'd like the TC to apply and lock in 2nd and then hold during the rest of the shifts. The...

I'm looking more for theory from the experts rather than problem solving. It has been a while since I've been on the board so I'll post the short version of my story.

I have a AWD Chevy Astro V6...

Hello Russ, Thanks again for the help with this. I have keyed it all in and am loading it in the am.

Since you are the expert here, I have a question regarding the TCC settings for performance....

Hi Russ,

Sorry I missed this reply. My tires are "factory size" but based on the manufacturer specs they are 1" larger than the prior brand. I put some stock sized BFG AT's and a 2" lift kit on...

Thanks Russ, I always appreciate the help.

Sorry for the delay, we are in the middle of yet another Disney trip. She towed nice except for the 2-3 shift.

I took a quick look at my factory file...

I was hoping someone could give me a hand with this one. File attached.

In tow/haul mode at about 32 - 40% tps I have a very sloppy 2-3 shift. It is tune related, aka something I've done as it...

Holy crap that spark table pulls nice. Thanks!

Do I need to worry about 100% tc lockup? Does it put any extra stress on the TC when towing that much weight? I guess lockup is better than slip...

Hello All,

Well some more Disney trips and tuning have passed since my last post. Just wanted to say thanks again to all who have helped me with this.

Latest data is 10.5 mpg around town...

Ok, when you have picked yourselves off the floor I actually do have a question about this.

When towing the travel trailer, even though the Astro is AWD, I feel the rear end drop and then bounce...

Hey guys,

I saw the employment opportunity link on the front page of the website and noticed one of the locations is in Orlando. Do you have an office up there? I'm kind of stuck down here in...

Thanks Russ,

Attached is the stock tune. I'll make the TCC settings and torque reduction changes tonight after work before the drive home.

I figured torque reduction was still enabled by that...

Thanks to Russ and EC_Tune, I finally got around to making the suggested changes and it worked great. The low end of the 1-2 shift ended up a bit harsh so I backed down a bit in the 0-100 lbs of...

My 03 Astro has the 4.3 and I am up 2mpg and about 15lbs of torque according to the trans torque meter. Check my babbling towing thread as there are some recent copies of my tune.

I'll let the...

Shorter tires?? GASP... Actually they are just 1" over stock so I did not go overboard. But I have looked into the gear change, although with AWD that gets pretty pricey.

The LT1 swap is...

I'm using hptuners, with outstanding success, to improve the towing capabilities of my V6 AWD Lifted Astro van. I know this differs a bit from most everyone else on the board but I was hoping to get...
