434 EFI Update
I am getting a few miles on the new EFI 434 motor. It is running pretty good now. It starts easy and runs strong. I get between 13 and 16 MPG. It might be slightly rich at idle, and it blows black smoke at WOT. I have installed an Innovate LC-1 Wideband O2 sensor/controller. I need that to correct the MAF Transfer curve, so the EEC gets the proper air information. Unfortunatly, the LC-1 needs to be calibrated. I have to use a DB9 to USB interface cable to connect my laptop to the LC-1. The Radio Shack DB9 to USB cable that I have isn't compatible with Innovate. I have ordered the correct cable from Innovate. It should arrive on Friday. I am going to the Craftsman Truck race at Dover Downs on Friday 6/1, and Carlisle All-Ford Show on Saturday 6/2.
The truck is in the shop right now for some planned body modifications, so I will not be using it or taking it to Carlisle this year.
It will be Sunday 6/3 at the earliest, when I can get the MAF Transfer curve dialed in. I'll change the oil at that point also.

Where can I find you on Saturday? Will you have a vehicle in the show?

scramble box
I think I still have one of them around in my old networking kit 
Also think I still have an old breakout box. At the very last, I was working fiber--.
Dan, if you can get the pinouts and a "weller" solder station, then build that db plug of your choice! I have to build about the same for an old "Megellan" hand held GPS to usb interface. Send me your 434 (as security) and you can use my Weller.

The new cable came yesterday, but I didn't have time to try it. Possibly today!

Pinouts
Danlee--
If it is a db9 (serial port plug) to a USB plug, I think I can get/have pinouts. Will look out back in the tall grass for the diagram. USB pinout is all the same (Pretty sure).

Google "USB" and see what happens! LOL

module
Ahhhh--Soooo, The plot thickens!
Now that I think about it, (I try to avoid that) the harness for my GPS (external battery hookup, plus bare wires for USB/Serial port) has a module as well!! We must investigate--. Bet its for protection of some sort. Current limiting (like ni-cad battery packs have) or leed reversal protection. Gotta be something like that. Serial ports are ISO std----I think.

DB9 is RS232, which is 9 volt signals, ifI remember correctly. USB is probably 5 volt signals. Plus USB has some on-board smarts, while RS232 is dumb.
If I plug the USB side of the cable into my laptop, the laptop recognizes it. This would not happen with a RS232 serial interface.

Rs232
Really making me activate portions of my brain that I retired--!
Dont recall the voltage of serial sigs, thought all logic sigs were ~ 5V (dc). RS232 std had DCD,TD,RD, etc. and was 8 leeds. Could (and frequently was) be DB25. Also RJ8 mod plugs could pinout RS232, but dont recall if RJ8 could be officially designated as "RS232". I recall various stds for RJ8 mod plugs including cat 5 applications.
Gawd, my head really hurts now
. Guess I have to quite dreaming about 434 and look at comm plugs.

Sorry to double----
The USB port is probably seen because of a termination on the TD-RD (looped back like a loop-back plug) even though no equiptment is attached to cable---in fact, I'll bet the module has something approximating a loop-back with diodes that allow the cable to be hooked up without causing an alarm or tbl indication. Seems like I used to give loop backs via same method with TD/RD on RS232 plugs--kinda fuzzy now.
