IC pump operation, by chip

[SBNova]

Has anyone had good luck altering their IC pump operatiion by altering the tables in the chip?

After changing my IC pump, my new pump is a little loud. I decided I would leave it off until IAT's hit around 105 F, or engine temp was over 170- on its way to being fully warmed.

I am running $59, but these tables should be the same as $58. The only one I could get to make a physical change was the hot coolant temp. The IAT fields wouldnt force the pump on. I also have a MPH table, but even at 0mph the IAT wouldnt work.

Nothing?....... Nobody has played with these tables??

I tried them with my autoprom but didnt get any response from the pump- other than the one field listed.

Ive read everything on NWSTP, I guess I will give it another try.

I'm gonna ressurect this thread.

Trying to get the pump tables to run an electric fan on a friends truck. SO far none of the changes I've made have changed anything. Currently the fan runs ALL of the time once the engine is started, and this morning the coolant temps never got above 120 (Making the 11k+ samples I got in a log for Autotune useless ....I too am using $59 BTW )

I'm also a bit confused as to wether I should be editing the cold fan enables, the hot fan enable, or just the regular fan enable. The XDF file from NWSTP has all of those listed, however I'm not sure which ones to change. I had the thought of simply changing them ALL to the desired on/off temps, but I'm not sure if thats a good idea or bad idea. I'll have to think it over at lunch some, as well as try a few things tonight with the chip, and report back the results.

Re: IC pump operation, by chip

Did some playing in the chip on Mikes truck.

High enable is now set to 170 degrees
Low enable is now set to 160 degrees

I made those settings in all 3 of the fan "categories" Cold, Hot, and nodescript.....Seems to be working OK.

I also set the enable mph's to 0mph, and 35mph (low and high respectively)....HOWEVER, the truck cools down so fast once it's moving that I can't get above 35 mph, and 160 degrees at the same time to see if the fan turns off at that temp. I'll have to see how that works out when it warms up a little. I suppose with no inner fenders, and a good radiator and 20 degree temps it's not hard to keep the engine coolant temps super low. On the drive into work I saw an average of 120degree temps....unreal!!!

In the end, I'm not sure which setting needs to be changed, however I know that using the stock IC relay as a trigger for another relay to run the fan works, and having all three of the categories set the same also works....I'm probably done tinkering with that area.

Back to VE tuning I suppose.....I'll report back with more info on how the Autotune, and other tinkering is going shortly. The truck started WAY WAY out in left field, and I have a feeling it's going to take quite a few tunes to get it near close. It is making forward progress though.

The code was originally written to run a fan... IC operation was an afterthought.

Simplest method:
Set KFAN2THH to a really low coolant temp. Set kfantm1 to 1-2 seconds.

If you want to get tricky with MAT, you can do that too, but most folks don't find they need that.

Section 18 goes over the fan operation... it's pretty dense, but it does explain it.
$59 is no different than $58.

Thanks dig.....It's working as intended now, although the clarification is nice.

I'm heading back to the P4_doc now to read up on the MPH logic...Although until the temps outside get above 17, or I change the T-stat I think thats a moo point.

Re: IC pump operation, by chip

I printed that section and reviewed it. I could not get any IAT values to change anything. I have the MPH's set to zero, and only one table would change the enable. I think it was hot fan enable, and both high and low had to be set similarly. I never played with these fields in $58, and I didnt think $59 would be any different. I was tired of having my IC pump kick on every time I turn the key, and I wanted the engine to start warming up and the alternator to begin charging before I added the draw of my larger IC pump. I set it to come on at engine temps of around 57c and it seems pretty good. I would love to get the IAT section to work though, so it could come on at about 110F. I think I have enough pump volume to cycle the water effectively when the IAT's get hot.

When setting the enables for coolant temp, there is a high and a low.....You want to set the low where you want the pump to turn OFF at, and the high where you want it to come ON at. Seems way backwards but when you think about it it works out that way.

Basically the temp needs to come up to the high enable to be turned on, then as the temps fall it will get turned off as it crosses the low enable.......

I have the MPH set to 0 on the low, and 35 on the high, with the logic of it comes on at 0mph, and as the speed crosses the 35mph range it turns off
