had this happen a couple times recently... on a laptop I upgraded to Win 10... no idea if that is related. But I haven't reinstalled the TP software... I've had it a few years now.
Just a quick update. I have not yet resolved the problems with the Sparkfun FT232RL but I'm still working on it. I'll let you know what I come up with.
What happens is that the USB adapter appears...
Remember me from 2 years ago? :D I'm back to messing with DIY ALDL setup on my 7747, wanted to share updates. Hope it's not old news. Using Sparkfun FTDI Basic Breakout 5V with an emitter-follower...
The Jeep Grand Wagoneers with cruise control have an inline vehicle speed sensor (VSS). I finally pulled mine to have a look at converting it for use with GM TBI, instead of having to buy an...
Thanks! I will take a peep.
I've narrowed down the cause to a problem somewhere above my neck. I botched the vacuum routing, EGR, etc., I may have been experiencing a big vacuum leak on top of EGR enabled with manifold vacuum....
I'll post up when I attempt to reduce static timing and see if I can get it to run at 0*BTDC
Looks like 450-500 (neutral) base idle which I assume is without vac advance but with base timing of 10* and 600 curb idle (drive) which is with everything hooked up. The 600/10* was common across...
Aw crap. Ok, I'll check that out too.
Heh, no doubt. :) Well, I'm not going to disassemble *right now* ... and more than likely I'll just read thru the pdf and call it quits. :)
Thanks for the help once again :)
Yes, it reads ~14.5 on two different gauges.
I will try increasing both parameters.
Same here. I've never been able to get one of these AMC motors to run without a little base timing. You could set distributor to 0 and add in timing in the SA table, but it wouldn't idle with the...
1227747 $42 ASDU, AMC 360 V8, 86 Jeep Grand Wagoneer. Timing is based on the 'basic timing' table on Binder Planet. I've zeroed out the PE spark advance. At all but near WOT it drives great.
I'm...
Here's the site I found: http://www.exatorq.com/ludis_obd1/spit.html
It has various EPROM images for dumping the ROM. You're right; it doesn't use the standard ALDL pin.
Thanks guys. I didn't want to pollute the other thread with this question. :) Supposedly one can pull the image without desoldering using some pins exposed somewhere. Unfortunately the website that...
Where might a fellow dig up an already-dumped ROM image (not EPROM, ROM) from a 1227747?
I'd like to, for my own curiosity, disassemble the ROM + EPROM code to get a better sense of how the code...
I haven't tried reassembling, yet but I think there's a good chance I can get it to disassemble into something that reassembles into the exact bin file. I haven't dealt with the parameters (data)...
I threw together my own 6801 disassembler in Perl, so I could (a) illustrate why I was confused by the posted ASM files (b) have more control over disassembly.
Here's the original ASDU1.asm file
...
Oh, actually that's what I thought you were doing. I get it now -- the hacked bins are actually bins someone already hacked and you're reverse engineering what changed in source (e.g. lots of data...
Ok, I follow. Where does the asm source come from? Someone else must've disassembled, I guess?
Do we know what microcontroller/microprocessor is used by the "C3" ECM? I thought it was a variant...
Quick question -- what disassembler are you using?
I think the issue has to do with the offset RobertISaar mentioned but I get your point too. I was already aware of the addressing modes. I've...
Nice work on the disassembly! I hope I'm not intruding but I'm one of those folks interested in the code as well as the tuning.
I do robotics and embedded programming as a hobby. I did a tiny bit...
Thanks, will give that a whirl.
Ooops, of course.
Ah, that makes sense. So realistically the engine won't ever see > 13" vac at 4400.
Sure, gotcha.
But... I made the mistake of using Bill's timing table from here without actually reading the rest of it talking about PE Spark. I hadn't zeroed that out and I suspect that I should...
I want to talk through setting up the Main SA timing table for a stock AMC 360 V8. I'm working on timing tables by looking at stock timing and starting with Bill USN-1's table from Binder Planet and...
