I did not know that about the nGauge logging fewer PID's. I guess that makes sense as you can literally make a configuration file with every PID/DMR available in Live Link then port it over to an SCT device. I love my GTX...but hate having to download each log before recording another one. I did learn my GTX can automatically upload logs via wifi....that's great if you have a wifi connection lol. I might have to get fancy with a wireless hotspot on my next track day.

This was the trouble I had when trying to build a log file for the x4. I talked to 5 star and they said do this and do that for the pid's but there weren't many exact matches for the what they asked, or there seemed to be duplicates. In addition, if memory serves, the x4 holds up to 40 pids, which was not enough pid's that I could check off following 5 stars instructions. On top of that, I did a pull when logging from 1 to 4 gear and sent them they log. They said it was unusable and they only wanted a 3rd gear pull from x to y rpm's.

I hear you saying I should keep the x4 and try to log with it. I would like that also but it hasn't worked out for me.....yet. This sort of leaves me where I started. I should have protested to the tuner when I found out he was using hptuners software, however I didn't really know all the ramifications at the time.

I tried this, the x4 wouldn't hold all the pid's. Otherwise it would have been simple

I need to come to Houston have you help me build the datalog file for the x4 and then go out and do some testing.

The whole problem in this scenario is that they couldn't get the transmission to shift in time on the dyno with the shorter drag tires. They put the street tires on it, which are about 4 inches taller, and dialed in the shifting with that, and it worked great. On the street, it shifts great with the street tires, even if they're spinning like mad. But when I go to the track with the newer drag tires, the motor won't spin up nearly as fast as it would on the dyno. They set it to shift early because that's what worked on the dyno, and it works with street tires if they're spinning, but with drag tires at the track, it has no trouble shifting in time so it shifts where they calibrated it.

The real question is what pids does your tuner want? x4 only holds like 26, ngauge holds 16... the more you add the less data points these devices reads.

Most tunes will only want a small handful for a type of log they want.

He can build you a config file in about 5 minutes and load it to your x4.

well this is what happens when trying to move from analogue thinking to digital, lol.

all good.

Do yourself and him a favor and schedule a road test.

Have some notes about what you like and don't like.

Both of you need to look at your dyno sheet and decide where your WOT (wide open throttle) shift points need to be in order to maximize the power band of your combo.

sounds good, thanks

I got back into live link and started looking at all the pid's. I think I can build a log file with the right information. I believe for now I will hold on to the x4 and do the logging with that, since it's paid for.

I got it all done today. Transmission shift points tweaked and the tuner set up the log file on the x4 for me.

It's interesting to note, because of the way the truck was shifting on the dyno, he had the 1-2 shift set at 4200 rpm...as low as it would go. It was still running past that shift point by 1600 rpm before it made the 1-2 shift. He tweaked all the shift points mildly upward. After the next trip to the track, we should be able to get it a little closer to being dialed in. Thanks again for your help.
