I've heard good and bad about their stuff. When I had my Z28 everyone that bought their Optispark usually had trouble with them. I've never used anything of theirs myself.

MSD used to be great stuff. Seems they've followed the path so many other great brands have gone ... :nonod:

 

I did my plugs around 75k or so, fearing they'd seize in the head if I waited to 100k. Was shocked GM actually used anti-seize compound on them. Miracles never cease! Used NGK Iridium, which is identical in every way to the OEM Delcos it came with. Kept the wires. The things are only 4" long - can't see them going bad this quick ... although lots of things automotive-related surprise me today ...

The only MSD wires I had fail were the 8mm ones.. the 8.5 mm ones have always been great and I still use them. A lot of their ignition stuff is junk though.

Accel is another brand that went down the toilet. I used a set of their wires, & cap & rotor on my S10 Blazer carb / HEI conversion. The wires had thousands of ohms more resistance than the old ones I took out. The cap/rotor look no better than the no-name stuff made in china these days. Sad.

The Fiancé and I took the truck to get dinner. Still having a weird issue with my A/C. I think it's something electronic mainly the control unit since it's messed up already anyhow.

GM electronic climate control systems are really bad. The ones from the 2000s would mimic bad compressor or low freon symptoms, making diagnosing those cars a huge pain. Pretty much EVERY automatic climate unit on W body cars had issues . If there is one still driving around with its original unit functionaling properlythey(over 100k miles) need to seal that thing in a air tight container and put it in the Smithsonian. And the buttons on the 900s.... I have read the systems on the 6th gen Camaros are having some problems also.

Yea, I'm not sure if mine is the original one, but if it is I'm suprised it's still working at all. A new one on Ebay is $120.

So I noticed that the picture of the truck I found with the Z71 emblem in the grille had it mounted a little lower than mine is. So I took the grille off and modified the mount some more to make it work. Looks a lot better in my opinion.

msd and accel, just know what you are looking for.

I use the 8.8 accel hot rod kit to make my own equal lnegth.

 

the msd 6530 runs a 1985 optical disty (first in the world) on my subaru... plug a lap top in and set the flat curve the boxer worships.

incredible stuff.

 

a lot of it is outdated out done.. just gotta be in the loop of what is evolving, what to throw away.

the 8.8 wires is silicon zero bleed, with kevlar and other goodies.

 

 

for my truck today, helped a neighbor move...4 trips the past 2 days actually.

I welded the back end, wanted to load it up with 1000# or so to see how it did anyway.

no problems at all.

I am also using hellwigs under the ubolt version (real version to me)

the truck was sitting level, thought nothing of it loaded.

I did not help them load it, so to my surprise unloading was a seeming endless pile of crates into 100 and 200 pounds a piece.

I laughed at the thought of 1500 pounds in the bed of my squashy half ton sitting level. I did not know it could be that good.

Smart idea. I've both seen and also heard of a good number of GM & Ford Trucks with seized plugs in the heads. "But they said I could go 100,000 miles on these plugs!"

Well yeah, they went 100,000 miles, and spent a lot of extra $$$ to get them removed as a result. And yes most of the time those plugs that came out at 100,000 miles looked like they had some life left on them, it was the fact that they were practically welded to the head that they didn't factor in. The Fords were especially bad. :rollin:

Seems like the Fords had issues keeping them IN the head, haha. I antisiezed and torqued mine to spec. Hopefully they'll come out as easily as the originals.

I've never had an issue with seized plugs when I put a good coat of antiseize on them. I actually have more issues with getting the boots off the spark plug end, and yes, I even coat the crap out of them with dielectric

The Fords would seize in the previously Helicoiled head on round 2, even WITH anti-seize. Now that's some engineering right there! :smash:

 

 

My truck has become a workbench, due to a "few hour" A/C job in our '93 Volvo 940 that morphed into a 7-day cluster***k.

 

Wrong condenser .... wrong accumulator ... wrong suction line ... unobtanium liquid line that twisted in half - 4 days, $50, & 90 miles of city driving to get one custom built. Even that got screwed up - would've had to wait 2 weeks for the correct fittings, so told them to use what they had NOW, which was a 90° when I needed STRAIGHT.

 

Managed after 3 full hours to bend, tweak, and fight the suction line into submission, finally installing it into the compressor. Batting 1,000 with this one. What a friggin hacked mess! Who wants to place bets on if I have any leaks after tweaking and bending these hoses all afternoon? :banghead:

 

I did a complete 100% system replacement in our '86 Grand Marquis, and it didn't take half this long, even with the wrong condenser (Rock Auto ... again! At least their return system is easy).

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Have considered installing a DC to DC charger in your camper to replace your isolator?

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
