I had a go at doing a v-tune run today.I loaded up the tuning map,opened datamaster and set it up to record and off I went.Well I did'nt even make the driveway.ALDL error,no prob's I think to myself just a loose plug.So I tried the rubber band trick,nope that didn't work so I tried jaming a piece of card in the USB slot...nope still the ALDL error.I tried the other two USB port's on the computer but still the same problem.Now i'm thinking this is lovely I've got the tuning map loaded on the bike and no coms to put the original map back so I can at least ride the thing.OK so I closed datamaster and loaded mastertune,click get ecm info and bang connected.Without touching anything I reloaded datamaster and tried again same thing ALDL error,buggered if I know.So i'm getting a connection through mastertune but nothing with datamaster,well at least I was able to reload the original map and ride the thing but I'm fugged if I know.Anyone got any clues,I'm going to try reinstalling datamaster when I get time and see if that work's.Cheer's anyway Waz!  

What version of the software are you working with? Look under "Help" then "About" in each software and it will give you the version number. The current version for both Mastertune and DataMaster is 1.5.7

Thank's Steve,but I'm running the latest version so that,s not the prob.I double checked the computer was setup right Gary and it's ok it's not shutting down or anything.It works fine sitting on the bentch collecting data,but as soon as I try and go for a ride I get this ALDL error before I get out the driveway.Can anyone confirm what this error is,I had assumed it was a bad USB connection but can't find any info in the guide about it.If it is the USB connection then why can I close datamaster and open mastertune and program the ecm with no probs?I had another 4 goes at it today same thing every time,It's starting to mess with my head and there aint much there to be messing with!! Cheer's WAZ

Cheer's for the input OZ,That AC power option could be interesting.I have'nt come across that,but have'nt been looking either.If it's cutting power to the USB port that would certainly cause the prob's Im having.I'll have a search through the power options again today,I have'nt found anything about hard drive shock protection yet either but the computer is'nt shutting down so Im not sure on that one.Yep I hope so to Hilly,all I can find in the tts help section is to check connections I've allready got 1/4 of a business card jambed in the slot,a 4 inch rubber band around the plug and stretched over the computer and a foot of duct tape holding it as well!The cop's where having a good look on a run yesterday,probably thought I had a bomb hmm.Thanks again WAZ

ALDL stands for “Assembly Line Diagnostic Link” . This is what come out of the ECU diagnostic port. The VCI box adapts this signal to serial which your USB adapter takes into your laptop. I've read on the GM forums (similar delco ECUs) that anything from a bad diagnostic cable to VCI connection, bad cable and along the line to your laptop could be the problem.  

Before you go on the ride, start data master and wiggle/shake all the cables, you may find a poor connection that only causes problems when stressed.

On the other end, perhaps you have a defect on the motherboard that only shows itself with vibration. If you shake the laptop in the driveway before riding, and you get that error. Do you have the laptop padded well enough?

 

The bottom line here, the ALDL error is not necessary caused by a problem with the laptop.

 

The current TTS works just fine with Windoze 7, been using it for a few months without issue, better than XP.

Thank's for the info Yositime,I managed to get a good run in today.Third time lucky maybe,I kept the laptop open sitting on a piece of foam on the tank.I've got a good stretch of road on an island about a km from home,nice straight flat tar road about three k's long and no traffic.so I got some good data using 2nd and 3rd mainly.It's a start anyway,have to see what happens when I try it in the backpack again for some highway and hill run's.Might take me a while to get syched up again before I tackle that tho.Cheer's all WAZ!!

I got to finish the tune today(hoooraaay)with two good long runs with no prob's.I blended the VE tables set the AFR & PE's back to origional settings left CLB's at 720,loaded it into the bike and went for a test ride.Did'nt think it was that good at 120 down the freeway til I realised I was in 4th not 5th,hmm seem to have gained another gear.So she's running pretty good but still very hot!(mid 320's F)bit disapointed with that but all in all running good.I have'nt been able to pinpoint the earlier prob's I was having,I checked the computer settings again but could'nt find anything tho I did change a few settings and secured all cables better(lot's of duct tape)It would have been nice to know what was causing it tho might have been able to help someone else down the track.Anyway thank's to all who offered up there advice along the way,Cheer's WAZ!!
