Hi guys
I'm running a Holden 5L with VR ECU and harness.
When the motor was stock it was running a BMZL 185kw vats disabled tune with no issues.
C1 input (engine cooling fan ground) would to trigger at 95 degrees to run the thermos and turn off at 89-90, I'm running an 82 degree thermostat

Since I had the motor rebuilt it has a stage 3 cam and other goodies in it, the Memcal came with the cam.
The motor is up n running well with the new memcal but my fans won't switch on at 95 degrees.
I'm assuming its a configuration setting with the memcal as i have tested the C1 input to ground and the fans run fine.

I have been playing with Tuner pro on and off and have copies of both Memcals.
I noticed besides all the engine tuning the differences the high an low speed fan temps are different which i have changed.
I burnt another Eprom and put it in, the engine still runs fine but the fans won't switch on.

The only other difference i found in tuner pro is in the Flags area, this is around the 2 speed fan option, the new Memcal has this enabled and the older BMZL tune has it disabled.

Should i disable it in the new tune??
Newbie in tuner pro here but i do have experience in similar areas.

Any help would be great
TIA

Yes, disable and re-test.

Hi guys
I have had no luck getting the fan to turn on
Any sugestions???

If you post up both memcals I will have a look at it for you.

Hi Kojab
I have added both bin files
I'm using 16183082 ECU and $12 XDF in tuner pro
The BMZL bin is what i was using in the past and the fans come on at 95 degrees
The crow cam bin is what i'm using now.
Engine still runs fine just no fan operation
Terminal C1 Blu/Wht wire doesn't go to ground to run the fans.
I have tested the fan circuit and the fans run ok by grounding C1 on the ECU
Thanks Mike....

You need to figure out what Crow have used as the base .bin file and find the correct xdf file to suit.

The company told me they used $12 version 2b.ecu

The Coolant temp setting to turn the fans on in the CROWCAM.bin was set on 110 degs C which is standard with a lot of bins.

CROWLC95,bin is set to 95 degs C

Hi guys
Problem solved, change a few more settings in tuner pro, now the fans come on at 95.
Thanks for your help

Sorry for the thread dig.

What XDF did you use to get into that bin, I'm trying to grab the VE/Spark tables from it for my crow cam and nothing I use is working.
