Re-torqued the U bolts before leaving town this morning. My dad used to design severe-service suspensions for IH/Navistar, apparently they re-torqued them all after 100 miles from the factory. He informed me I most certainly should get my butt down there and check the torque. Guess he's seen axles fall off on the teat track.
Sure enough, they all took about half a turn to get back to 200ft-lbs

Got about one mile down the road before the GVOD gave out. Seemed electrical since I wasn't getting any lights. Checked the fuse and poked around to verify it's getting power, after poking around and hooking it back up it worked again. So a flaky electrical connection somewhere in the rats nest. Added to the list of things to run to ground.


Since then another couple hundred miles have passed event free so far.

Pretty sure I'm living Bob's dream- i can watch the fuel needle drop while I'm driving

1000 essentially problem free miles* this weekend bring us to Peter's! Makes for an exhausting weekend.

And just in time too, home just got about 9 inches of snow

*The alternator belt will be the death of me

Initial impressions of the EFI system now that I have a thousand miles on it with a good pressure regulator - loving everything but the fuel mileage.

15* outside? Fires first crank like a new car

Climbing hills? Piece of cake compared to what it was, just ease on the accelerator a tad more and up you go. I never had to touch WOT once, maybe only once did I hit the 60% that triggers the ac shutoff relay.

Noise? Quieter than it was. Certainly not luxury noise deadened, but a notable improvement.

Gas mileage? Eh... Not great. Maybe about where it was, maybe half a mile per gallon worse. Haven't crunched the receipt numbers much, but high 6s or low 7s at best there.


This hasn't been tuned at all, I literally slapped the universal kit on, fired it up, said "sounds decent to me" turned self-learning on and drove 1200 miles... So I'll post update once tuning files have been reviewed by a human.

One nit, when the engine is already hot and you start it up, it will start at high idle and then lower to your idle setpoint rather unceremoniously. It's fine, but you can tell there is all the elegance of a computer trying to go directly from A to B. That's a really tiny nit thought.

That tells me your alternator is working too hard.

What size is your alternator and how do you have the wiring routed? What size is the wire from the alternator to the battery? You may also need to look at where the alternator "sense" wire is located. If you're using a 1-wire alternator you might want to reconsider that approach.

What type of devices are being powered by the 12 volt system while driving?

I've got a few alternator issues to sort out. The first is that I followed Dan's suggestion and looked at the belt with a straight edge, I believe it is standing proud of the crank pulley and therefore not lined up great. He mentioned changing the bracket to line it up properly made his problems go away. I'm not sure what bracket I can use to recess the alternator further back though, perhaps a pulley change. I'll look closer and try to get pics when I have the wheel off again in a day or two

The other issue is I am losing about 1.2 volts between the alternator and the battery. I can tell because I have my new dash gauge at the alternator output, while the holley system reports battery voltage. The dash gauge points just below 14 while the holley complains about getting 12.5 at the battery

I have the better style isolator that Peter installed on the way. Could be that will reduce the alternator load and fix some issues.

I haven't checked the sense wire location, I'll do that! Based on my symptoms I'm assuming it's on the low voltage side of the isolator

Given my tiny 40 gallon tank... If I didn't have to watch the road I think I could watch it move

Either my alternator or the pulley needs to move 5 or 7 millimeters forward

Put a ruler on some of the other pulleys just to make sure that your alternator is not just cocked at an angle.

one thing leads to another. Whilst bleeding Magnets brakes the Master Cylinder blew up. Now one of the brake lines is rusted solid to the master Cylinder. But my driveway is a good place for crap like that to happen.

Yep, heck of a lot better than while going down a mountain!!!

I'm enjoying the 70 degree weather so much I'm hardly even phased

Ps... Good picture of the aluminum Tetris

Master cylinder sure looks like a drop in replacement, napa for P30 with 4 wheel disc brakes. Should be the same one boom sounds and others have installed.

The micrometer says the distance from the mounting surface up and back down to the piston is maybe 0.008-0.010" different.

Unless anybody comes screaming in saying that's horrible, I'm thinking we're too far down in the weeds and I'll go ahead and install it. If this was a common mistake for p30 motorhome owners I'd think I could find something online, but since the internet is silent it's probably ok.

Got more serious about my metrology. Looks a lot better than I initially thought, averaged within the measurement error of the caliper

That doesn't sound like enough to make a difference. If the decimal point was one to the right then I might look deeper.

Just my $0.02
