Another option for $0D efan control

[1leg]

So do I just load the $OD mask into my 8625, then do the code changes. Sorry I'm a newb.

Yup. Basically same PCM $OD, $OE, $E6, $31. I don't know how versitle each is but like 16197427 is usually $OD for 4L60E but I just found one with $31 and manual trans, I have one already run on my test bench with a $OE which is usually 4l80E trans. But becuase it was the only manual trans bin I could find at the time I used it. So at least the 16197427 seems to run all mask bin files. Not sure if the others are as versitle?

As far as I know there for the most part completely interchangeable, but I did run across one conversation that some don't have all of the internal hardware for the 4L80E. It never became clear which ones though, sounded like it took a EE with a microscope to find out.

Yup just need to make sure the temps are located in the same addresses, and make sure the ouput channel is connected to the right pin.

When the suburban is up and running without issues then i will give this a try in my 93 truck with the 8625.

When you get ready, just let us know. The code can be adapted for $E6 or if you switch to $0D then you can use it as is.

Also, you can use the engine fan part by its self with a normal relay, if you don't need the soft start and transmission fan.

Thanks

I'd like to join in on this too i have two trucks with 8625 running $e6 that have E-fans, and don't want to try to copy all my settings over to $0D in fear of jacking something up.

How many things did you change? Wouldn't be that hard, just back up the bin. Take some time in TunerPro. Open 2 instances of TP, old bin new bin and cut and paste from old bin to new bin... you could do every option in an hour.

My theory, by looking at years is $OD was the last one made, 93V8S10 confirmed it with:

they probably found one PCM that GM tried to save a buck on for manual trans? Or just a 4L60E? On an early PCM and code mask? In the end they made one PCM to cover all trans and masks saved money. If it weren't for OBDII they may have gotten better and better?

Back to my theory of looking at masks $OD seemed to be the last one in this string of PCMs so it's a progresion to better and better, all options built in last one. Since we have found 16197427 which is also by looking at years last one, came mostly with $OD, but has been found with other bins and masks in it and has been changed to other masks. So last one GM made would be the best.

I'm only using $OE on $OD 16197427 PCM becuase a manual bin to strat with has only been found in $OE, I would much rather start with a $OD manual bin. To many changes in bins from manual to auto to start otherwise... wish I could find a manual $OD bin, always been my first choice.

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.

[Davis_1377]

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.

[PJG1173]

under fan b calibration you should have 3 scalars labeled "Engine or Transmission Temperature" 1 through 3. set them all to "AE" as per the scalar descriptions:

Engine or Transmission Temperature 1
Location: 70CD


Set to A2 (00A2 coolant temperature) to use Fan B for cooling engine.
Set to AE (00AE transmission temperature) to use Fan B for cooling transmission.


Engine or Transmission Temperature 2
Location: 70E5


Set to A2 (00A2 coolant temperature) to use Fan B for cooling engine.
Set to AE (00AE transmission temperature) to use Fan B for cooling transmission.


Location: 710A


Set to A2 (00A2 coolant temperature) to use Fan B for cooling engine.
Set to AE (00AE transmission temperature) to use Fan B for cooling transmission.

new at tuning do i add to existing xdf or open fan xdf after and set ?

[sturgillbd]

Easiest is to just open the xdf when you want to change the fan settings. Be careful to double and triple check the code you are adding to your bin for e-fans.
