Welcome to AKM Electronics' web site!

Here you will find products to help you monitor and tune your GM car, along with as much technical information as we can pack in to a web page!

September 24, 2008 Now that this Ike business with the web site is out of the way, I'm trying to get things back to normal (web site was down for a few days, server got moved, I couldn't update it, email trouble, yada yada yada). The AKMCables.com server is located in the Houston area, and was without power.

I'm still very committed to selling the best cables in the business - I have hundreds in stock right now, so I'm not going anywhere. Also still committed to selling TTS Datamaster, the best scan tool software available for certain OBD1 cars. I am shipping daily, within 24 hours of receiving orders!

Our cables connect to many different GM ECMs/PCMs, typically ranging from 1986 to 1995. They do not connect to Dodges, Fords, or most other manufacturers. An exception to this is manufacturers who used GM computer control system components, such as Lotus - we do connect to some Lotus automobiles. Software can be found at links to the left.

USB Trade-Up Program! So you've got one of my RS232 cables, but that shiny new laptop you are admiring doesn't have an RS232 port on it... what to do? Take a look here for some options.

Universal Serial Bus Information A lot of newer laptops don't have RS232 ports on them. If you've ordered one of my USB cables, here are the installation instructions. It does require a software driver to be installed (CD included with the cable).

PCM REPAIR INFORMATION: Sometimes, programming gets interrupted when flashing an LT1 PCM. Unfortunately, it happens - due to a laptop thing (power saver mode; screen saver; anti-virus; battery dying), or the cable can be knocked loose. If it happens to you, email me and I'll try to help. I do know how to repair PCMs, but I honestly don't like doing so in a 'rushed manner' (as in, "I need this PCM shipped back to me by tomorrow or my head will implode!"). But if you need one repaired, shoot me an email, we can work something out.

Cable Assembly Notes For you folks handy with a soldering iron, hopefully this will show you enough to build the cable. :) Click here for the Schematic of the AKM RS232 cable. I do not have a schematic available for USB cable, I never made one, lol. And the parts are so small that a kit is really out of the question (it requires some skill to assemble).

Having trouble getting your laptop connected? Download our Serial Port Troubleshooting Document (Word97 Format, about 90kb) or the DOS Boot Disk (for LT1 Old Tunercat Users) Document - note that the new Windows version of Tunercat's software does not require switching out to DOS any more.

The most common applications for our cables include:

Now, you'll notice that we don't sell some of the items we describe. Why is that? Well, we receive a lot of email asking various questions, and rather than keep this knowledge to ourselves, we like to spread it around. Maybe one day you'll purchase one of our products, but even if you don't, hopefully you will learn something while you are here! We do appreciate your feedback. And if you have anything to add, or correct, we're always happy to hear about it - we definitely don't know everything!
