I have a 92 truck with a 303,000 mile 350 TBI in it. It has an 16146249 ECM in it. The pin outs appear to be the same as a 7747 ECM, can they be swapped? I am getting ready to start burning chips & there is a lot of info on the 7747 & none on the 6249. Getting a 383 SOON.

6249?.
Sure it's not 6299?.

Auto tranny?.

Yes, auto trans 700r4. Not sure yet, I will have it out again in the morning & update.

Yes it is a 6299 ECM

Good luck on finding help for the 6299

WWW.Tunercat.com has you covered. Mask $99

I believe there is a hac on the net for it.

Mr. Grumpy what do you mean by: there is a hack on the net for it, Sorry, I'm Computer illiterate. But I do thank you for earlier help on connecting me with Tunercat, I'm slowly gettin further along on this journey to learn this STUFF, thanks in part to people like you who take the time to answer ?'s. :hail: :hail:

A hac is a conversion from machine language to english. It allows a human to read thru what is really happening in some thing that uses a processor.

A hac of an ecm, shows all the table, switches, and settings possible. Most editors just show, what's most often needed by the average guy for tuning. The code allows for such details as the time that it takes for the coil driver to swith on and off, which would in theory never need to be changed.

Any ideas as to where on the net that hac might be? Thanks.

Try http://moates.net/fileman/index.php?...%20and%20Hacks

I found an .src file there. I need an .ecu file, does it convert ?

Well, you asked for a hack, not an ecu file

I don't recall having seen a $99 .ecu posted anywhere.

But, the hack gives you the information you need to make the .ecu file. Open the .src file with a text editor, and you'll be able to see the memory locations that you need. IIRC, Mangus has a how-to paper on the TunerPro site.

HTH,
