I can enable it with the scanner, so I know it's wired up right. But I have something screwed up so it won't enable. Maybe one of the AC enable settings?

anyone care to take a look? i'll owe ya one.

 

$25 bounty? help me out. really wanna use fan 1 output as an rpm trigger for my boost controller and i'm too dumb to remember to turn my fan on manually.

 

Cant view the file. what ecm are you using?

 

p59. probably the damn attachment manager for this site is broken again. you got google drive?

 

No I dont.

I just got hp tuners and have been messing with it. It seems like the cooling fan stuff is so much simpler with the 411 ecm vs the newer ecm's like the e40 in my car.

 

Yuu have the fan 2 enable/disable temps where you want them but they are not coming on?

 

i was bored and happen to have vcm editor on this laptop but the attachment is messed up

 

yeah the damn attachment feature on this site has been broken for a month

if you have google drive

if not PM me your email i'll send it to you.


thanks dudes!

 

yes but fan 2 is also linked to the AC conditions. currently i have them zeroed and i'm not sure if that's right.

 

under ac dont you want the a/c disable at 0 rpm, not 8,000?

 

I had a similar issue on a friends truck (s10) swap. I can't remember all of the ins and outs of what we did, but it was a combination of making sure the platform type, system type, and fan type was all in agreement. It took us a couple hours of trial and error to get it right. We also had the same thing, could enable the fan with the scanner, just would not come on via the ecm.

 

yeah I thought that was the rpm at which it would disable the fan so i set it super high

 

thats exactly what I think the issue is. it was a gto pcm, now running a van OS thats been dicked with to enable flex fuel.

 

i have efilive so i cant edit your file but i compared it to mine which works.
my platform is gmt800, yours is 610 but the options table for your 610 matches my 800.

i have all my ac pressure values maxed out, not just the max ones but the min ones also.
you said you have a van os? what type of ac sensor? the fbody os uses a sensor and the trucks use a on-off switch. i would think the vans use the same as the trucks.
on temp ac on: 70f
all your delays are zeroed out. mine are not. not sure if these matter, but factory OSes do weird stuff sometimes since these variables arent always fully figured out.
turn on delay: 5
turn off: 2
min run: 10

hope this helps

 

I think that is exactly what it was. RonSSNova gave me some values and now it works. Need to do more testing on the fan 1 circuit to see if it actually turns on at a given mph to use it as a boost by mph

 

BTW, what is this in? I hate to assume its a swapped c10.

 

yeah it's in the '77 swb i take to the racetrack

 

What's wrong with a swapped c10

 

Nothing, just making sure it is a swap and not a factory full size. Your reading too much into how I worded that.

 

I think RP has a swapped truck too
