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! January 3, 2012 - Well, it's been a good run. 12 years of selling cables, and I have decided to close it down. I'm not selling cables any more. I have sold my last bit of inventory and sent all of my designs to Tunercat, so you will now be able to purchase USB cables from him. Click here to go to Tunercat's web site.
Datamaster Customers - I will still obtain authorization codes for you. I'm not stopping getting the codes. Just email me and I'll get the code for you. I know, my web site is still a mess. Links are broken, pages are missing... ;) I may fix it some day... Looking for AKM USB Driver download, Windows 7 Information, etc? Click here. These 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. 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). AKMCables.com OBDII Information - some frequently requested information for those with 1996 and newer vehicles 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. . I do know how to repair PCMs. I am no longer repairing PCMs. I recommend talking to Ion at MadZ28.com - he can repair PCMs. I do have binary chip images here on my web site at OBD1-t.bin, OBD1-e.bin, OBD2-t.bin, OBD2-e.bin - the "T" is the blue/gray board, and the "E" is the red/black board. 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 these 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! Now for my "personal" pages and hobbies... (2007-2008) My 94Z Convertible is still on the road! Here's a fairly recent picture (July '07). It's gone through some changes over the years (it's on its 4th engine, for example). But right now, it's tucked down on a Bilstein/Eibach package, with a VFN 2" Cowl hood, a 96-97 SS Spoiler, a nice 383 with some mild heads / 230-236 cam under the hood, a Yank SY3000 torque converter through the original still-untouched transmission (ha!), rolling on Intro GT Sport wheels, and fully layered with Damplifier sound deadener... of course with A/C and all the goodies. It's heavy, but it's a fun cruiser that still gets 20+ MPG on the highway. Driven as often as possible, especially on these nice cool fall mornings (September 2008). My '98 Z28 When I had 3 broke-down Camaros, I needed something to drive (oops!). So I dug deep in to the money reserves (err, wiped them out), and purchased a nice used truck - a 1993 Chevrolet Suburban (and yes, I hook my laptop to it too). It's now the tow vehicle / daily driver. (Update: Was the daily driver. Now it sits parked, awaiting "hauling manure" duty :) at 13 mpg, it only goes out when needed). Shouts to Kelly Parker for the Logo! |
