matts srl cold start issues?

i got matts srl a month or however many back. it just got pretty cold in ohio and last night it got down into the high 20's at the lowest. then this morning it was prolly anywhere from 32 to 36 dont know exactly. my truck wasnt plugged in and wouldnt start. so i have had it plugged in all day and im gonna try to start it tonight again. does anyone else have problems like this???
i would just plug it in but i cant when it sits at school from 7am till 3pm, sometimes 6 or 7pm if i have practice or a game after school it will never start when i cant plug it in. so its either take the tune off or find somewhere i can run me an extension cord from inside school
OOOORRRRR i could just borrow my moms SMART CAR for the winter days to school(all my friends laugh when i drive it, show up in a mean loud truck one day then the next a little car. we park all the diesels together and the smart car in between) i will have to get you a pic of it next to my truck
let me know your guys input but i sent matt an email to see what he says but i dont know if he will answer. i feel bad if i bother him during the holiday

Some racing tunes can give you probems during cold starts. I have never had this issue with any of my tunes, but they're not from Matt.... YET

Matt should be able to help you, I hear he's very responsive to his customers

Oil has a lot to do with the no start. If you are running a "summer oil" it will be too thick to start at low temps. Also weak batteries might be to blame. Enough juice when it is warm but the cold will put more strain on them.

Does it just crank and not fire or will it not crank at all?

I dont run any of Matt's tunes but I run extreme street/race all year. Monday when it hit almost -30c in Edmonton my truck wasn't plugged in(over night), it put up a fight but it did start after 5 min of trying.

SRL starts great. Fuels heavy in cold weather though LOL.

Check your battery voltage and FICM voltage

first try: cranking started to puff a little black
second try: puff black started for a split second died
third try: cranked, puff black
fourth try: cranked, puffed

i prolly could have gotten it started but it was my fault i didnt plug it in and didnt want to beat it up

you might have a couple injectors sticking. you wont notice it when its warm but when its colds the injectors tend to stick until the oil thins out.i just recently had a couple bad ones myself.

+32 or +36F is not cold at all for a PSD. Even with 15W-40 oil mine starts just fine down to 0F without being plugged in. Mine has started at -10F, but it did hit pretty hard and run rough for a few. I think you have problems other than tuning.

Check or have checked, the amount of current the glowplugs are drawing(when cold). Something is amiss.

FICM voltage would be more pertinent to check than glowplugs on a 6.0.

Glowplug failure in a 6.0 is unheard of.

Sounds almost exactly like a low FICM voltage case. With a touch of injector stiction.

While I agree a 6.0 will start down to 0 with 15w40. It doesnt like it much. 5w40 is a much better winter oil

Sounds like your FICM is getting week. My old 2004 would start in the Mountains of Colorado at -25F after sitting for a few days not plugged in with Rottella 15W-40 oil. I always let the glow plugs heat for a good minute or two then crank it. It would chug black smoke for a minute or two but would always start and run fine after it warmed up for a few minutes.
