Set Temp for Fan relay with Laptop
I want to lower my relay kick on temperature for my radiator cooling fan with a Laptop. I guess I need suggestions on what the very best software that I can get for this and all troubleshooting / modification purposes. I have an ALDL cable but the end that plugs into the laptop is missing, so if someone has a drawing of one, I can make it up. I wonder if the cable would be universal with all software or if each program requires a specific set of resistors. I would really like to learn to do something usuful with my laptop other than snipe corvette manuals off ebay, lol

You need more than a cable to alter settings on a 90. You will also need an eprom burner, and a spare chip. You could erase your stock chip and reburn it, but I always leave the stock chip alone just in case you need a back-up.
TunerPro RT is an all in one scanner, eprom editor and emulator program. I use it with my Moates Autoprom, and with it you can tune on the fly with a factory ecm.
Using this software/hardware, I can also tune in real time on my GMC Typhoon and run closed loop wideband !!! Pick any AFR you want, wherever you want it.

You have to get a chip burner too I believe (might be wrong). The cable should be the same for the laptop, but the cables for OBD1 and OBD2 are different.
I'm using Moates cables and TunerPro RT, the software is free. I'm not into custom tuning, just like to see if everything is up to snuff.
I know on my 87 I changed the fan switch and wired it so both my main and aux. come on at the same time on 200-205 off 185, at least on our earlier C4s you can do it without having to reprogram the ECM.

This what the C.Moates APU1 (emulator) set-up looks like. It is an expensive move if your only interest is changing fan temps. Craig sells this as a package w/all cables, programming and a couple of blank chips.
However if you become interested in the life long pursuit of 128, it offers some real good options. This allows you to re-program/adjust all parameters of the ECM instantly, including data logging, chip burning/reading etc. Mine is also interfaced with an LM-1 (afrm) in real time to the lap top.
