ALDL interface
I just got an old 486 laptop for free and downloaded WinALDL so I can monitor the sensors on my '85. I am making the cable to connect the serial port to the ecu as described here- http://winaldl.webhop.net/ . So I want to run the car in aldl mode right (10k ohms at the r3 position on the diagram)? It is hard to see if there is a resistor in that picture of the diagnostic connetion of the car. I think there is, but it is hiding and a bit blury. I just want to be sure b/c I don't want to mess anything up. Thanks.

Re: ALDL interface (black85)
It is not any resistor in the picture, but you should use one. Some cars need it and some don't.
WinALDL reads the 160 baud data and should work with all MAF TPI Corvettes
The '85 Corvette is 160 baud only, but the '86 up MAF support both 160 baud and the newer 8192 baud data format.
The early digital dash get MPG data from the 160 baud data. I don't know about the new dash desing, but I don't think that they use the 160 baud on those.

Jonas,
Just wanted to drop a note to you since I saw you here and it reminded me to do so.
I built a cable and used winaldl last week for the first time. I was tuning a 1227747 in a 91 CK-truck that a friend put a '96 Vortec motor in with a Ram Jet 350 cam and GM's alum TBI intake that's made to work with the Vortec heads. I've done a few of these now but they've all been a little different. I liked the idea of your BLM table populating and averaging in many ways so I thought I better give it a try. I must say, it is an absolutely wonderful program. Saved me a ton of time on the VE tables and I couldn't believe how close we were after just one 20 minute log run. Got almost all the BLM's to around 125 which is where I like them. Just wanted to say GREAT JOB and thank you. I dropped you a few bucks on your PayPal Donate button from the site too. Thanks!!
