    Dave, is that bin you posted set up with 93V8S10's fan code, or the version posted up by Six shooter?
    I tried it with my test bench. I looked at it first with 93V8S10's fan controll XDF, and the temps were set all strange, so I changed them to lower them down some. I ran the test and the light simulating the fan came on and went off, but not at the temps I had programmed into the bin. But then I thought, maybe you have six shooters fan code.

    Well I spent the past couple days playing with the hex editor, figuring out where the addresses are, finding where the stuff is supposed to go, etc.. So I figured I would give it a try myself. I could not get copy and paste to work, so I ended up having my girlfriend read off the values to me while I typed them in manually. I saved it, burnt it to a chip and tried it. Same thing as the bin that was patched by marks XDF, everything jumps all over the place, fuel pump/relay click on and off fast.
    So either we are entering in something wrong, missing something, or there is something wrong with this code. I compared the bin I manually entered to the one I patched with marks XDF, and everything was the same except for the checksum.

    I guess I am going to try the FSC code next.

    Well I went back and double checked everything and it appears everything is entered in like its supposed to be, unless I am just overlooking something. So without the author here to help, I am just going to have to give up for now on this code. Its just way to over my head trying to figure out whats wrong with it.

    So I figure I would give the FSC code that six shooter posted up a try. Started with my bin, had my girlfriend read off the values as I typed them in, saved, burnt to a chip and gave it a try in my test harness. No jumpy data or fp/relay. TP connected fine, ran the dizzy and used a heat gun on the CTS. My noid light (simulating the fan) came on when it should, went back off as it should too. Seems that code works fine.
    I finish up the wiring on my jeep and go for a spin. Fan cycles on and off and seems to work as advertised. So I now have a working E-fan controlled by my PCM.

    Would kinda like to figure out whats wrong, or what I did wrong with 93V8S10's code. It has some nice features, like the ability of soft start and a second fan. But its over my head and would take someone smater than me.

    Since you typed in in and had same results as my patch method, I'd say there's something wrong with the code?

    Glad you got the other one working!

    Were the E fan XDF parameters I added to the $0D XDF any help with old/first E fan code.

    No, I was about to post up about adding the parameters to the XDF.
    On the FSC code, some of the addresses are the same, but what they are/do is different. So we probably want to delete them from your XDF, or change them and the patch to the FSC code instead untill we can figure out what's wrong 93V8S10's code.
    I can add the items to my XDF, but it has been so long since I have added a new parameter I need a refresher to do it. Copy and paste I can do fine, but adding a completely new one I have forgotton. I know how to add it, title it, discribe it, and enter the address. But its what I put for size and output type, and if I need to put anything in the conversion tab, and if I do, what I need to enter into the conversion.
    Here are the items listed on the FSC code that need to be added:

    Calibrations:
    L7000 19 db High MPH Fan Cutoff (25 MPH)
    L7001 B9 db Coolant Temperature Very High Value Enable (210 deg F)
    L7002 B1 db Coolant Temperature High Value Enable (199 deg F)
    L7003 AA db Coolant Temperature Low Value Disable (190 deg F)
    L7004 2D db Minimum Fan Run "MFR" Time (45 Seconds)

    Anyway to change coding to also use fan #2 output as engine temp instead of trans temp? Im wanting 2 temp settings cause my fans have low and high. Very efficient as on colder days the temp is consistent on low.

    yes as this is how mine is set up, read the instructions in the setup bin file. there is a bit that needs to be changed to select coolant temp for each fan.

    I don't see it in the instructions how to change the transmission fan to 2 engine fans. Looking in tunerpro rt i see some scalers and flags I don't see option to change this.
