tried logging with the desktop, dual core intel 2.8ghz, the EE def on TP site worked better than the one with 20ms pauses added, but still had flickers of erratic numbers. in the log you can see somewhat steady and appearing to be accurate numbers, but every so often something garbles the data (?) a...

i think i've figured out the structure of the macros and commands and how they work, but what the individual commands are, i'm lost. i know they're hex, but dunno where i'd find a reference of sending what command nets what response from the pcm. but i'll try this pc before going through the choppin...

i'm just hoping to read dtcs at this point, it started throwing a SES light, scanned it couple days ago and it was left o2 lean, want to see if it's still just that or any more, without having to drive down to oriellys to use the autoxray scanner. and yeah it seems once it gets past 50% it starts er...

replaced 7805, added heatsink and couple caps before and after 7805. still same DANG!. gonna set up everything on desktop system and drag that out there. this whole thing is makin me saad. could an adx be made to just read DTCs and that's it? while not running, it seems to log decently untill i pres...

another thought, an autoxray codescout 2500 is able to read codes from the car, if that means anything.

only things computerized i have access to is a 90 dodge with a TBI 318 swapped in (originally a v6) and the rest are OBD2. does TP do obd2? ive never looked into that...

when (trying to) log mine heats up till the point of burning skin, but sitting idle it cools off

i built it exactly to the schematic you posted, nothing more nothing less. power is fed on some 18 gauge speaker wire, the wire to the aldl plug is an old multimeter probe, and a serial cable.

do you use heatsinks on your regulators? i thought since it's so little current it shouldnt be needed.

it would go fine for a few seconds, then count like 4 to 8 errors and then go to the erratic numbers.

i might have to drag a desktop out there again and see where it gets me, although power is a bit less of a convenience now

hey robertisaar, im not dead, just had a bunch of "life" to deal with. living situation changed then my niece came into the world 3 months early. I havnt had much time to play. I tried the new $EE you sent, and was still getting erratic data. I played with the delay from 20ms all the way u...

i must not have gotten it yet, no it was the old adx on the site. i'm gonna check the email right now. to add to my headaches, the onboard LAN in my main computer here in the house took a dump yesterday, so i have to boot this laptop every time i want to get on the net. And i dont have any network c...

a little update.. a winxp box does the same thing, totally erratic numbers and 3-4 hz sample rate, even with the car not running. So i dont think it's the laptop / linux config. only errors i get were when starting the car, about 7 errors then it started streaming right again. if anyone has any idea...

I got the max232 interface built, using robertisaar's schematic, and got SOME date from the car, the problem is that it doesnt seem to be right. in the item lists, the numbers jump around to crazy values (rpms from 1200 to 6000) It seems like the serial port settings aren't right, as if the word len...

WOOHOO! my parts just got here, so I have to finish my daily chores and then I can start putting the cable together. the car wont be home till round 3 or 4:00, so I've got a little bit of time to get it together. They max232's were actually maxim, not ti or some other knockoff. I'm getting excited a...

I looked for DB9s, but they didnt have them. the only REAL radioshack around here went out of business, it was a little franchise where they knew me by name for 11 years. and that was an 11 mile drive from where im living now. now all we have is the ones filled with overpriced RC cars, computers and...

just ordered enough parts to build 5x of the interface that robertisaar posted a schematic of. cost $7.94 after shipping, I also bought a few extra parts not needed for the interfaces but will still come in handy with things i'll be fiddling with. now i wait 7 to 21 days for shipping.

so now my interface(s!) wont even pass the little test in tunerpro. before i was at least getting that, from all 3 computers i have. I built another, from scratch. with, and without the 9V battery, im not getting DANG!. either i blew out the serial ports on all the computers or something. I guess my...

the 2 transistor cable was a fail on the dell with winxp. So i'll be switching out some parts and see how it goes, gotta put a few $$ in the bank tomorrow before i order the parts for a max232 interface. thanks again for the help robertisaar, and massively huge thanks to mark for all he's done with ...

first you have to determine what car you want to tune, what computer it has, how you're going to interface the romulator. once you have the interface connected and read the rom, you'll need definitions for your bin and the aldl interface (im not sure if you'll need aldl definition for romulator) the...

the next step.... I'm getting together an old AMD K6-2 400 machine to run win2k, the comp should run on less than 100 watts. The plan is to run the computer on the inverter, monitor on extension cord. If all is well and I can actually communicate / log, I'll be able to boot computer, get everything ...

what was cost on shipping? and i figure it wont be much to regulate 12v down to 5, my laptop only has one usb port, and im using it for the flash drive.

i use a modified(cleaned up for stuff i'll never use, like 160 baud, and the mode sense stuff) version of the techedge schematic. the other one is WAY overcomplicated. so the max232 is fine with just the resistor and diode for pcm side... splendid, less soldering i'll have to do! edit: is the CTS e...

so it's a pre-v5 ads you guys used to test the import function? i'd gladly give it a shot. my email is drunkenwhippet@gmail.com and the 44 cents for the max232, that's at digikey's 10,000 unit price break. nice! how is shipping from thailand? off topic, since being laid off, i decided to persue a fo...

OK, so i've seen a couple differend schematics for max232 based interfaces. http://www.techedge.com.au/vehicle/aldl8192/8192hw.htm and http://www.mindspring.com/~amattei/aldlif.jpg anyone have experience with both? the biggest difference I see is the one uses external transistors to do the pullup/pu...

I guess i didnt mention part of my situation. im dirt freakin poor. When I first started reading about tuning and everything, I was doing good, 50 hours a week, making good money. my plan was actually to buy a netbook for a couple hundred $, build a max232 cable... but a month later I go from doing ...

you've been through these 2 on dynamicefi's site, right?

that looks like a pretty decent step by step to tuning your computer, and should be able to help you narrow down to specific questions.

did you set up the port in the tools, preferences, data acq./emulation tab? have it on the right port?

in order to do a test from there you'd have to connect 12V and gnd to the pins in the plug, since it gets its power from the aldl connector.

I've picked up a considerable amount from googling the term "lt1 pcm tuning" and doing alot of reading.

is it all controlled by the stock pcm from the 95 GMC? did the engine builder tune it? or is it still running on stock tune? (scary)

Hey everyone, a bit of an odd situation I have here. long story short, data acquisition failed. unplug from aldl connector, cable test passes. I'm running TunerproRT v5 on a laptop with no hard drive. I'm running puppy linux from a live CD with swap and storage partitions on a USB device. laptop can...
