new chip effect glow plugs?

[kokanee kid]

brother-in-laws 95 obs, installed new bullydog 6pos chip and his glow plug light shuts of within 2 seconds even in cold wheather. One month later mine 95 obs, installed new tw 6pos chip and the same thing happens, glow plug light shuts off within 2 seconds. The glow plugs remain on as you can see the volt draw for about 2 min. whats going on?

Not sure about the GP light, but my truck does start easier and faster when the chip is on the extreme setting compared to the stock setting.

this happened when i had to get a new pcm installed on mine to, i think the chip probably just updates the programing, you probably had an older one before hand. they usualy stay on for a couple minutes regadless if the light stay on or not anyways

The '95s had a TEE5 PCM code in many of them. This code would keep the WTS light on for a set amount of time reguardless of engine or outside temps. The newer programs are probably based off a TDE0 or TDE1 PCM code that determines by the engine and outside temps how long to wait to shut off the WTS light. Typically the first start in the morning while the engine is stone cold and the outside temps are colder it will stay on for longer. But once the engine has been run much when you restart it will shut the light off much quicker.
