Seeking knowledge. Goodwrench 350, 89 TBI injection, Surging

**Sonomanclature** · 03-31-2015

I'd like to have the stuff to do it myself. But it's going to be a while before that can happen. Our trip got canceled this year since we had to buy a new car for the girl. Sucked all the funds up quick.

ASDX is a 350 manual bin for the 7747 ECM. It is very well documented, and Mark and I worked on getting the ECS done and highway lean cruise patches in it.

Too bad there isn't some one locally that has the stuff I need. Hopefully I can get the cable setup this coming month, then at least get a data log for more knowledgeable people than myself to look at.

AKAN is from a 1987 5.7 with M20 (465) Manual trans if you hadn't looked it up already. I may have a 9pin serial aldl cable that I made a few years ago. If I can find it, I'll pm you and send it your way. Here is the schematic and it took about 15 mins to build. All of the parts fit inside of a 9 pin serial connector shield. Works great for 160 baud systems but not at all on 8192 baud stuff. It can only receive data, not send.

As much as I wish I could, I cannot translate that into Physical placement. Circuits have been a struggle for me since forever. Might be able to find something on Google easier for my brain to wrap around. IM pretty sure I have everything though. aside from a Serial connector, and a laptop with a serial port lol.

the above is what similar to what I used when I made my first data log cable. worked fine on my 8625 below are pic's how it turned out. here is what I based mine off of. http://cable.invisibill.net/

Here is what I use now. Just twist the RX and TX wires together and solder to a pin. Solder the gnd wire to a pin and connect the gnd to pin A in the ALDL. Connect the RX/TX pin to the serial data (either E or M depending on the ECM) . Was less than $20 shipped when I bought one. Looks like it has increased to $14.99 now for the cable. It works great though. http://www.superdroidrobots.com/shop...i-5v-ttl/1619/
Also look at this thread. These little boards are cheap on e-bay. http://www.gearhead-efi.com/Fuel-Inj...ight=Uber+Easy

Well I should be able to get a cable to start Data logging this week. Here's hoping.

i also picked up a second 7747 ECU, with a AKAJ Memcal, Just to see if myabe it was something in the other chip. It didn't make a difference, but now I have a second ECU to fiddle with.

Ok, I finally received my cable and downloaded TunerPro. I was able to log a little over an Hours worth of data driving various conditions, town, light to light, highway, interstate. my speedometer reading is inaccurate, as it is reading double actual speed.

So here is my log file, hopefully this will help to get some of this figured out. Thank you in advance.

Well some things have changed, My old laptop died so I have finally replaced it. I have simce replaced the engine I was running with a rebuilt engine from a 92 k1500. THe specs that have changed from stock, are .030 over flattop pistons, a Melling MTC-1 cam, deridged throttle body with AFPR 13.5psi, and an Airraid throttler body spacer since it came with the engine. I have about 300 miles on it now, and it runs a hell of alot better than it did before. I'm having one issue where it will bog when hot after sitting while turned off for about 10 minutes, it cts like a map sensor, but I have only been able to catch it once while logging.

The first log i did, there were no issues on this run, it was dead cold then drove for about 20 miles, varying conditions.

The second is the only one i have so far that I was logging while the bog happened, its about 50seconds-1:54 before it levels off

If any one would like to look at them and give me any input that would be great.
