Glowplugs cycle during warmup, is this stock?

[JeffsJeep04]

You will appreciate GL4's revised Glow-Plug timing control feature. With it, Glow-Plugs are energised for a longer time before startup and are cycled on and off during the early part of the warm-up period. This feature vastly improves cold start performance and reduces exhaust emissions during the warm up.

Saw this on Heath's site today, my truck cycles the glowplugs after it's been started for a few cycles (light blinks on and off for about 30 seconds). Is it possible I've got an upgraded computer? The PO did put a turbomaster on it, so I'm wondering. I need to get some gauges so I can turn that thing up

That is normal for the stock PCM.

Figured. Why is this touted as an upgrade by heath?

his cycles a lot more than stock, at least it seems like it... I actually find it kinda annoying, all my lights dim periodically for almost a minute after starting, and IMO once the thing is running it doesn't need the GPs

I'd imagine it's harder on the alternator as well. A fast idle would probably be better for all parties involved when it comes to warming up the beast.

The fast idle mod sure did help in getting my truck to temp on cold morning. IMHO it is probably one of the best mods anyone could do.
