Well, I thought it did the trick, but it may have just slowed the appearance of the CEL. It still re-appears after I reset it.

Can you tweak the previous map you sent to make the low coolant temp CEL go away for good? Can you use the last map you sent or do you need me to send the current map back ...

Perfect... that did the trick.

Thanks!

Hi Diablo Folks,

Could I please have another map updated to fix the P0128 CEL issue? I recently installed a Vortech Supercharger and it's included map does not have a fix for this issue, even though they include a lower temp thermostat in their supercharger kit.

Enclosed is my last tune written ...

Called in... One of your efficient tech support reps helped me reset the tool. I'll try to update the tool and reflash the truck tonight.

Thanks!

Awesome, I'll bring it into work today. :-) You guys are amazingly responsive on this list. I have a Predator for my Dodge Magnum as well and got a quick update for a coolant temp fix for it here.

Any idea why a download to the ECU would fail? The ECU has been updated at least once by the dealer ...

I tried flashing my 2008 LMM with the 100hp tune using the U7186 programmer.

I initially let the programmer download a backup of my ECU, then started the 100HP flash. The tune seemed to be loading fine, but after a couple minutes it said there was an error loading the program into the truck's ECU ...

For people who are not having problems... I wonder if your temps are just not as low as those who are. We all might be right near the threshold of throwing the code. Some may be a degree or too above, some below.

Since it's pretty common for people who update their thermostats to a lower temp one to get the OBD2 code P0128, how about either automatically turning on the fix for this whenever the fan temps are lowered or make it a user modifiable parameter in the Predator? Ditto with the O2 sensor codes.

Yeah ...

Thanks, I'll load it ASAP!

Hi folks,

I have the P0128 coolant temp too low CEL after setting fan temps and installing a 180 degree stat. Can you please update my tune to clear this CEL?
