DHP cable set up help

Hmm weird then why have i heard of people having problems with it plugged in, or maby thats just plugged into your car charging.

This is a problem with HPT. There is something power/ground related with using an inverter or plugging the laptop in via the lighter sockets that can fry an HPT. DHP doesn't appear to share the issue.

DHP also takes a lot longer to read/write along with pestering you about car voltage etc unless you change settings. DHP and HPT are both fussy in their own ways.
 


how long does it take HPT to do a full flash and a partial flash (if they have that option).

I know on my DHP PT, i can do a full flash in ~4min, and a partial in ~45 sec. and you only have to do the full flash the first time you load that particular file, and then partials only after that. and you cant brick a PCM on a partial flash (at least i have never heard of one).
 
i guess those 1.5mins and then the 17 secs are very important to some people lol. im not sure i would exactly say that it takes a "lot longer" to flash/read with DHP PT. sure, base it off of % of difference then yes, it seems like a lot, but not really if you break it down into actual time difference, ie 1.5 min for initial flash, and 17 secs for partials.
 
FWIW, I've never had a 4 minute write time with DHP on full. It's 8-10 min for a full.

Some vehicles have to be written in slower modes etc.
 
i just had 2 full writes done yesterday, on my regular PCM and my backup PCM, one was 243 seconds, and the other was 236 seconds. and this is with a direct serial connection, at 115,000 baud rate and 1024 byte block size, on an old ass dell d600.

i have seen my initial reads take from 5-8mins occasionally. the one time i had a write take more than 8 mins, it failed and bricked the pcm (which was a not matching hardware number, but "compatible" according to others).

i am also sure that there are many people using all kinds of different laptops with a wide range of specs considering that the time these units came out, there was a transition from single core laptops, to dual core, to mobile versions of the same processors. with a range of 256 to 2gb of ram available, i am sure there is a wide range of times to be had.


my laptop is a d600, Pentium M 725 1600mhz, and 2gb ram
