Read/Write issue

[TwoFast4Lv]

Tried about 9 times yesterday on a duramixer with no love. Seems to be hit and miss with theses things. I will try low speed, how long does that take???? It has been avg. 7-8min for me to read and write them.

Charge the lap top battery real good and hook it up. start the read and come back 20-25 minutes later

I have to pull the TCMB 10 amp fuse under the hood of my dads 07 Classic with Allison. Otherwise I can't read or write to the VCM.

Heck I tried pulling all the fuses some of the hand helds have you pull to no availe...Except when I pulled the trans fuse

Low speed today takes 2-3 times till you get a good write.

I tried to back up my tune for the first time since upgrading to 2.18 and each time about 30mins in it died.. and reset my radio clock.

Well I tuned a 05' low option Dmax today. It went GREAT!!!!! I was so happy, I read it in one shot in about 6min. Then the writing went off without a hitch time and time agian in about 2min. I wish it would be like this for every one I do.

Well I was playing with the 03' today and it worked great on high speed every time. Maybe the update I got works. Also I did a 01' yesterday and it went off w/o one trouble. Nice huh.

I still have the same issues with my truck. I have to read the entire thing on low speed mode. Basically set up the laptop and hit go and then go do something else for a half hour and come back. Frustrating to say the least.

Do you have any aftermarket adapters hooked up to your stereo? My dad has a Sirius radio module and I have to unplug it to get HPTuners to read and write. Anything non stock that is plugged into the stereo system will mess with reading and writing the PCM.

[JuniorCruzer]

From an electrical stand point my truck is completely stock minus a trailer brake controller and a radar detector, which I have unplugged and has had no change to the issue. No other modules at all. Only additions to the truck are visual accessories and a 4" exhaust. I have not even hooked up my boost or EGT gauges yet.

Yup. 19 times out of 20 mine will fail at the TCM in high speed mode. Every once and a while it will go through with no issues.
