Data gathered so far


Fans
MUT AB
Mask #1 = 0x1
Mask #2 = 0x2

AC Hi:
Mut Command (Actuator 0, Mask 0x1000)

AC Lo:
Mut Command (Actuator 0, Mask 0x800)

Main Fan Hi:
Mut Command (Actuator 0, Mask 0x400)

Main Fan Lo:
Mut Command (Actuator 0, Mask 0x200)

When i activated the fan it used mask 0x1 then added mask 0x2 later perhaps the coolant temp decided this. Despite what command I set. I'll discover which settings does what later with a running test and will just simply pay attention to the fan and variable timing with the AC On and then Off.

Kinda late to the party and i just skimmed over it. So you just want the fans on constant once started? Just use the starter signal output (pin 71) from the ECU to trigger a DEI 528T Delay Timer to activate the fans a few seconds after cranking.

 

Just updating this to let you all know my life has become needlessly complex leaving me no time to do work on this rom. In the process of trying to get a new house and the number of steps is quite daunting. If I do find additional time to work on the rom I'll let everyone know

 

roadspike, I appreciate everything all you guys do. Sorry to hear your life has become so complex, I hope it's not completely overwhelming!

 

Its not that bad just eats away at my free time.

 

david just out of curiousity how are planning on running sd? are you running it directly from the ecu or are you using a harness similar to spoolinup's

 

did you ever make any progress with this?

 

Nope, as far as I know it was never all finished. I'm happy enough with the Haltech, I don't think I'll switch to anything else.

 

if you master the sd tuning i could tell you atleast 5 guys i know personally who bring there car...

 

david will be tuning my car on SD this spring. full buschur built car..

 

Why not just have your water pump come on with the cooling fans and then set your cooling fan on temps a little lower than what you normally would?

 

That idea will not work for a few reasons.

 

Yeah, now that I think about it, the temp sensor has to have coolant flow past it to know the temperature to turn the fans on...duh! This shouldnt be that hard to come up with, maybe I can work on it.

 

to my knowledge david said he had no interest in tuning on sd

 

I have tuned a few SD cars Mullen.
