ECM reading with a PC ??? can it work ??
 

Hello !!!

Have anybody connect a PC to a Mercruiser 1993 502EFI ???

I have found the free software: DataMaster

DataMaster-M3 Beta v3.4.21
NOTE: Only works with MODE1 Datastream which must be enabled in the PCM firmware.
Supports MEFI-3 Marine and GM Performance Products Ramjet 350 / 502 EFI systems.

And i have a datawire from PC to ECM !!! from:

www.mastach.com

i have connect the PC to A=ground and G=Datastream
but nothing at this time !!! We have bad weather at this time so i test it more in the next days !!!

Have anybody a idea ???

Mit freundlichem Gruß

I'm surprised someone hasn't done it. I use vag-com for my VW so I can get in there a muck with every computer system onboard from my laptop.

Rinda has a PC based system:

I use the laptop program from Rinda!! what a great program!!! the best feature is the record feature!!! You can run the engine normally , then view the data.. You can also Email the data you have recorded... I like it much better than the scan tool. you can watch 50+ different paramiters at once, instead of just one at a time like on the scan tool. well worth the money!!!

Oh !!!

I have hope in USA someone have test and used this way to read a ECM from a Mercruiser !!!

In germany nobody can help me !!!

Anybody else, can help me !!!

Thanks, I wonder what Arizona Speed and the supercharger companys use to reprogram the mercury ecm's. Maybe somebody knows!

OK Rinda software Diacom Marine are the best !! Have you a Rinda testprograme ??? Or can anybody make a copy for me ??

If you can help you are my gast on the next Oktoberfest in München !! You drink - I pay ! :-)

I know az speed cant reprogram the 496 motorola ecm so they use a new delphi one.

to MikeScarab: We work with the Rinda software, but it
is only for analysing the engines parameters and you
can not recalibrate or reprograming the ECU.
It's not what you need whan you like to change some
ECU parameters.

Na Prost und viel Vergnügen am Oktoberfest!

Gruss Daniel

Yes i now !!! I dont want reprograme the ECM i will only analysing the ECM !!! Can you help me !!!

You can Share and copy the Rinda software all you want, and even install it in as many PC's as you want, but it won't work when you go to plug it in the ECU. There security protection is in the Patch cable itself. You can purchase the program between a few friends, but you would have to all share the same cable.

I have had a lot of Diacom problems on Windows XP. I haven't used it in a year but hopefully they have improved it since then. Datamaster is a very good program. The software is a free download but you need to purchase the cable and reg#. Then the cable will plug right into the laptop. It also works great with Windows XP. very stable

They most of improved it robyw1, because I purchased mine August/03 and have had no problems on my desktop or laptop running XP. :)
