Erratic Electrical Truck - Don't Know What to Make of IT
All meters/scopes need a ground reference. You'll want to attach that little alligator clip to ground (or a wire that then attaches to ground). The scope probes usually share a common ground, so if you're using multiple probes only one will need the ground attached. Without that you're... -
June '23 Chat - Will BBT be in the wedding?
Yeah, you'd think there would be an existing safety/visibility law they were breaking. I think that style looks retarded, like a dog taking a [emoji90] Sent from my FlashScan V2 using Tapatalk- DAVe3283

Clunking in 4wd Forward or reverse...about every 5 feet (lb7)
I ran with JB weld on mine for almost a year before I got it repaired. Sent from my FlashScan V2 using Tapatalk- DAVe3283

June '23 Chat - Will BBT be in the wedding?
I'd get high 20s/low 30s on 87 octane in the Gen 1, but would consistently get mid 30s and sometimes even approaching 40 once tuned and running premium. I don't miss the car, but I do like the 1.4 motor itself. Sent from my FlashScan V2 using Tapatalk- DAVe3283

June '23 Chat - Will BBT be in the wedding?
When I tuned my 2013 Cruze it got really picky about the octane I ran. Interestingly, even stock the mileage would be enough worse running 87 that it cost the same as running premium. So I always just ran premium since it cost the same per mile, but had more power. When my brother bought his...- DAVe3283

LB7 stock turbo longevity and upgrade options?
Where's your sense of adventure? :P I've been running a large S300-based single for nearly a decade now and I see 1300-1350°F sustained when climbing hills. I imagine the stock IHI should tolerate that fine too. From what I have seen you will run into oil temp (and therefore oil pressure) issues...- DAVe3283

SoCal Lb7 Duramax
As stated, the vacuum pump runs the EGR, so removing it will cause a check engine light because the EGR won't work anymore. It might be possible to run an electric vacuum pump instead, but it begs the question of why you are removing the mechanical one. If you fully remove the EGR system, you... -
Keyless entry failure?
Tom, what probably happened is your truck battery went dead or the fobs battery was disconnected. That causes the rolling code to get out of sync. You can either re-learn the fob as you did, or hold down both lock and unlock buttons on the fob at the same time. That causes the fob to rapidly...- DAVe3283

Keyless entry failure?
Be very careful with eBay and Amazon fobs. They are all Chinese clones, and have the same crypto key in all of them. The only thing that is different is what position in the rolling code they are in. I discovered this the hard way when my neighbor would leave for work and it would unlock my...- DAVe3283

01-10 steering box redhead ,PSC ,OEM
It sounds like your powdercoater didn't do a good prep job on the surface. I have a liftgate on my truck that's powder coated and it gets the crap beat out of it, metal drug across it, drug on the ground, etc. There are several areas I've gouged through the powder to bare metal, and the exposed...- DAVe3283

Another issue with coolant.
That doesn't look like coolant to me, that looks like oil. Which could easily be a valve cover gasket, turbo oil return, etc. Should be easy to tell when you pressurize the cooling system. If it doesn't leak down or start dripping, then it's probably an oil or fuel leak. Sent from my FlashScan... -
Another issue with coolant.
Sorry, missed the part about the drivers side. Like Ron said, the oil cooler is the likely suspect. If the oil cooler is just leaking coolant to the outside, the engine would run just fine. The coolant comes in the front of the cooler from the water pump with and o-ring gasket, then exits the... -
Another issue with coolant.
Could be the coolant block-off plate on the right side of the rear engine cover. They are known to leak now and then. Sent from my FlashScan V2 using Tapatalk -
How much should I trust FASS filtration?
I run an AirDog, which might not capture water as well as the FASS. Ran the Suburban out of fuel right after we built it (hadn't calibrated the fuel gauge correctly for the swap) and a tow truck dumped in 2 gallons of, it turns out, water contaminated diesel. The AirDog water separator filled...- DAVe3283

Fleece Freedom Series Heads?
I put S&S SAC45 in the Suburban, but I'm somewhat regretting that. They have been a pain in the butt to tune, won't clean up at idle, and have poor balance rates. They run fine under load, but I'm getting really tired of smelling diesel every time I'm stopped at a red light. They smell as bad as... -
Fleece Freedom Series Heads?
The heads seem good so far. They appear to perform like stock, but with the bonus of no injector cups to deal with. I got them on sale, and at that price it was a no-brainer. I don't put a ton of miles on the Suburban. I have less than 10,000 miles on the new heads, so it is hard to comment on... -
FRP regulator fuel flow command
Usually it should be in mm³/sec, and it is the ECU's estimate of how much fuel the engine needs at the current load. There is a lookup table in the ECU that takes the mm³/sec value and gets the regulator current in mA. It uses that as the baseline for the regulator command. There is also a PID... -
How hard is it to scale LBZ fpr for lb7
I think there is a small theoretical improvement in peak flow using a LBZ regulator. But IMO the main reason people switch is the newer regulator is often cheaper and readily available. If you aren't having problems with yours, I wouldn't bother replacing it. Sent from my FlashScan V2 using... -

2001 lb7 duramax fuel issues.
You'll want to log the truck when it does it. Could be dropping rail pressure, causing extremely long pulsewidth, which can do all sorts of weird stuff. Low rail pressure can be caused by worn injectors returning too much fuel, or a weak CP3, or a leak. But without a scan tool and taking some...
