Another option for $0D efan control

[93V8S10]

ok looked up those solid state relays $40+ not quite in the budget right now. guess this will have to wait and I'll concentrate on finishing the tune.

Try these:

I may be missing the obvious here but why wouldn't a regular/cheap/stock relay work?

[93V8S10]

The soft start code is PWM (Pulse-width modulation), it switches off and on rapidly to create a less than 100% output. This creates a fire storm inside a normal relay, leading to a very short life.

The rest of the fan code can be used independently of the soft start, with normal relays

i didnt think that the soft start would work. the way the relays are wired they come on at about a 50% spin at the first temp set in the ecm and on high only if that is needed.

I think I'll order a few of these when I get my taxes back and wait for you to finish expanded code, since I don't need the trans fan for this truck. I will definatly be using it on my other truck when I get to it. I'm starting to get too many irons in the fire...

BTW thanks for all the work you have done to support this community/hobby/addiction. I didn't realize until recently you wrote all the ADX files I pulled from tunerpro.net.

Thanks!

Got the expanded fan code done for $E6 and $0D, $0E/$31 to come later. This should be able to run a wide variety of set-ups. I have tested the $0D for basic function, I'll leave the final testing up to you guys. Let me know if you find any problem and if you like/hate it. If you'll like it, then it may find it's way into the Advance v275.xdf.

Enjoy:

If I can figure this out without blowing something up I'll try to implement this weekend and see how it goes.

Ok working on getting this setup in my bin and I have a few questions.
I have a dual speed fan
1. if fan A is active will fan B be set to inactive or do I have to wire the relays so both the high and low relay's won't be energized at the same time?
2. tps for fan on. is this the tps % if I want the fan to come on reguardless how fast I am going? will this override MPH for fan off?
3. if I don't want to use MPH for fan off will leaving it at 0 disable it or do I need to set it at some really high number same with TPS?

As a source for solid state, dual fan relays of automotive grade may I suggest 2003-ish and up Dodge Caravans? In the stock application one relay is used to control two fans independently. There are a couple of versions but both are fairly small and would easily mount in a 3" by 5" space. They are usually found on the LF frame rail, LH inner fender, LH side of bumper, or under the LH headlight. Be sure to mount them to a nice solid heat sink as they will get hot and will die if not cooled. Dorman 902310 (pictured with the connector) is typical of the version mounted on the bumper while Standard DR1088 is physically smaller and can be found on frame rail, inner fender, or under headlight. The 902310 is slightly more reliable but will require plenty of airflow for cooling. DR1088 should be mounted to a good, solid metal base which won't get too hot.

1. if fan A is active will fan B be set to inactive or do I have to wire the relays so both the high and low relay's won't be energized at the same time?

That's a good point that I didn't think about while putting this together. Both Fan A and Fan B will be on separate relays and both can operate at the same time. So will this hurt a two speed fan? I don't think it will, but at the moment I'm not sure. (EDIT: Looking at this further, looks like for a two speed fan you will need wiring that prevents both speeds from operating at once. I'll try to come up with a schematic.)

2. tps for fan on. is this the tps % if I want the fan to come on reguardless how fast I am going? will this override MPH for fan off?

Yes, this will override everything else except "Overheat Temperature for Fan On".

3. if I don't want to use MPH for fan off will leaving it at 0 disable it or do I need to set it at some really high number same with TPS?

If you don't need the MPH for fan off then set it to the maximum. The "TPS for Fan On" can not be disabled, but if you set it to 100% it will operate the least.

I don't know about the first relay (902310.jpg), but I have tried the second one (dr1088.jpg) and it will not work with this code. I don't remember off hand exactly why, but had to do something with a timed circuit, which may be for the A/C.

O.K , I give up , I typed all of the HEX included in the code above into the Hex editor in T/P for my .bin . How do I get the functions included in the fan control XDF that 93V8S10 provided to show up in my bin on the T/P parameter tree ?

Am I just missing something ?

Thanks

I loaded the XDF provided in the zip and loaded all the hex through it. everything showed up just fine for me.

Got it now :)

Don't know what the heck I was doing wrong , but its all good now .

Thanks
