this is what i have

oooo and i forgot it's in a 95 GMC yukon 1500 4x4 truck .

here are some pic's of the beast

 

Welcome and nice setup!

Yes, there is a lot of support here for the 93-95 truck TBI systems. The DIY-Prom forum is a good place to start.

You will also need to get prom burning equipment. www.moates.net has what you need. You will need the G1 adapter along with 27SF512 chips and a prom programmer.

 

welcome aboard, sounds like a good setup!

 

thanks

hey i'v been trying to get some data for my tunner guy at (tbichips) so he can see whats going on .i have a old laptop and the olny programs i have got to work is winaldl and tunnerpro but i'v yet to find out how it all works plus i need a aldl cable .is there any guys in here that mite have one for sale.anyway thanks for your comments

 

The cables are not too terribly difficult to build, if you know how to solder.

If you don't find a good deal on one, and you don't have any soldering skills, send me a PM, I can work up an "Ugly, but a goody" for you, for the cost of parts.

 

well i did make the adld cable that brian at tbichips has on his site but it didn't really work .but if know where i can get a good semantic at on how to make a good aldl cable that would be great i'm sure i could make one

 

Yeah, that cable usually doesn't work. You should build one with an external power input.

Try modifying your cable to the first schematic on this page, with the external 12v input (you can plug it into the cigarette lighter, if you buy the connector).

ETA: Also, don't use Resistors R3, or R4. They are not needed, and will cause problems.

 

ok great now will that cable work with my 7427/BJYL ECM

 

It sure should. Nothing to lose by trying!
