238/80's hazing at idle

[littleredstroker]

so I wonder... if a tuner could write a file specifically for cold starts? more or less timing At 200 rpm ?

200 rpm is only cranking. You want slightly retarded timing compared to normal so the motor doesn't fight itself when it's cranking.

This forum is lucky when tuners contribute their knowledge to it.

so is that something that you do on your tunes anyway?

at -20 at 5500ft cold starts are always a PITA. Anything that could help would be a blessing

I wish my 7.3s would start that clean above 50°.

Mine looks about like Joes after first started at about 35... it will stay that way until I can get EGTs above 400.. Its got a tired GP or 3

Same here, but its worse now. I think its glow plugs for part of it, but it will have to wait until summer.

How are you guys testing your glow plugs? I have always just used a test light, putting the lead on the Positive side of the battery and just probing each glow plug at the valve cover connector, if you have a good light, then you have good continuity to Ground through the glow plug. Legit?

The proper way to test them is to check each GP's resistance. I don't remember the acceptable resistance though.

yep visual test.... and if you see the tip is reduced diameter from use, time to replace them before they mushroom and never come out again.

Video of 300/200 cold start. No adjustments done to the Injection timing adder for EOT vs RPM. This was the factory setting for the Injection timing adder for EOT vs RPM.

I will do a couple more videos showing what the change is like adjusting the injection timing adder For Oil temp vs RPM map. I might or might not spell out how much each change is and where it was tweaked.

Sorry about the dirty Pickup! LOL

Yep. I figured it was that cold or colder. My 01 has a bad cylinder and the dually has always popped right off but it has always had a haze when below 50° on the first startup of the day.

Another video this time with the Injection timing adder advanced over factory tuning. By the time it hit 60 degrees it was it was cleaner then before. Another adjustment will be shown later.

Gearhead Hydra tuning "All Out" tune
Unlimited 400cc/200% injs
18F air temp
12F oil temp
overnight, no plug, not driven in 5 days, truck has been driven 17 miles since HG replacement, probably still have some air in the HPO sys.

After 5 minutes of idleing (Gearhead "Whisper" tune)

Gearheads Hydra tuning with the new 4 line is the best my truck has idled...ever. I'm sure other tuners have idle figured out too, just posting my experience. The reason for the engine compartment shot, is to show no "shake, rattle, and roll" like I've had before....he'll probably say it's the same tables, and he didn't change a thing now ....but I'm just sayin'

 

[TyCorr]

Whats the line going to the hpo reservoir?

Your truck is about in the same condition as mine. Underhood is where all the candy is at,lol.

That thing idles exceptionally well.
