Very interesting. If someone makes a complete XDF (or whatever it is called in their program) for the jeep 4.0 cal, I would be very interested. I have yet to convert mine over the the GM ecm (life...

I have pretty much all but given up on the stock Jeep ECM. Its a great ecu, tough and durable, but as far as tuning support, there pretty much none. An those who can do it, will not share. This...

I guess the only way to really tell would be to actually compare the bin files. If I could get this cherokee auto trans ecm and bin file defined and tuneable, then I would purchase another wrangler...

So, basicly your saying tunerpro is not gonna work with the jeep bin files?

My jeep is a 93 wrangler 4.0L 5 speed. The spare ecm I have is actually from a 93 cherokee 4.0L auto. I dont mind...

Ok, back home. I pulled the top off the spare ecm I have, and it looks a little diffrent on the inside than the one in that link, but I think I got the correct numbers.
The numbers goes as follows:...

Still learning. What is ment by functions?

So can I use the moates autoprom to read the EPROM? And for that much, if you can use the ostrich to emulate, I'm guessing I could also use the autoprom?
If so, do you know what offsets I need to...

Not sure how I could find out. If your not having any luck finding out, I doubt I would have any luck. Would the numbers off my ecm help? Its the factory original ecm, and its a 93 wrangler 4.0...

Seems like a program you can put on a laptop and then use a simple USB cable with interchangeable ends to connect to the diffrent aldl plugs would make way more sense than the seperate scantools. You...

Well if the datastream for OBD2 is standarized, what about code, and tuning? Could you swap to a OBD2 jeep ecm and harness and have easyer tuning than the obd1?

That 99 grand cherokee I bought is...

Yea I understand its only data coming out of the ecm, and not a way to tune. But I still think it would be nice to be able to datalog, even though I cant tune it. It might give more insight into...

Taken from another thread on this site:




So anyone know if one for my factory jeep ecm could be found and made to work with tunerpro? Would be nice if I could atleast scan and mabey datalog...

Nope, never heard back from them. I havent called either, usally too busy during the day, and when I do have the time, I never think of it.

Sounds nice. I am definately not having much luck on my research. But I have been kinda busy/distracted lately.
Definately keep me updated on what ya find out.
Getting the chip out wont be the...

This is in a soft top manual transmission jeep wrangler. It controlls nothing but the engine. :laugh:
I have forgotten one thing. It also regulates the alternator. But that wouldnt be hard to...

The factory ecm is underhood, but I wouldnt ignore anoher option if it was a under dash unit. It wouldnt be much more work just to run some extra wire and mount it inside. Whats the datalog speed on...

Megasquirt looks like a very nice system and I have nothing personally aganst it. But in the back of my mind I just dont want to run a fully custom ecm. I cant help but thinking if something freak...

Well it looks like the ecm in my jeep is whats being called a "SBEC" ecm. Its used in lots of the same year range dodge and chrysler vehicles. Seems like the dodge ones have been hacked some and...

Looks like I have plenty of reading to do from all those links. Might take me a little while to get through them. But it looks more promising than all the rest of the info I have been able to find.

I bet anything it has been done, but like said by cmaje72, its probably been on a shop level where they make/have lots of money and hire someone fulltime to do nothing but hack/tune the ecm.
My...

About the only gm ecm/pcm I think I would swap to, would be the 1220411. Its sequencial, has great aftermarket support, and can run a 6cyl. But its just so freaking expensive to tune. It would also...

So I have done some google work and constantly come up empty handed. My daily driver is a 93 jeep wrangler 4.0 straight 6. It has the factory sequencial multiport injection. With all the fun I have...
