General Supercharger Thread

Sending positive ju-ju in your general direction

I wish you quick remedy

 

This is what just freaks me out about this stuff. Something happening to the innards!!!!???

Best of Luck to you!!

 

Are you aware of any tuners in your area that use VFTuner? It has a Force Flash function that if I'm understanding it correctly, should essentially "unbrick" your ECU. If memory serves, this will install a base factory N/A tune. From there you should be able to flash your latest ProSpeed tune.

 

Just found this channel. Dude is awesome at teaching. Explanation of wheel hop on a high HP Tundra

I spoke to Matt Wilson, of VF Tuners, and he says the ECU I have is one of the harder ones to unbrick and he'd need it on his bench to do so and it would require opening up. I'm waiting to hear back from him if it's something he's willing to do for me.

In the meantime, I've got another ECU on the way just so I'm prepared to start over if needed.

 

Will definitely add these when I redo my rear leafs and suspension.

 

Those SDHQ traction bars are pretty slick. Almost 3x the price of caltracs but I guess that’s the price of no lost offroad capability.

 

That is exactly the selling point for me.

 

Which ones need adjusting a good bit of the time???

 

Not sure of them needing adjusting. @nobodyintexas has the caltracs, maybe he can say if those do or not.

 

yup.

Caltracs need about a month of dialing in.

which means my tired ass had to get on the ground and adjust them.

they are fine now.

as advertised, that contribute to proper adolescent driving techniques. zero wheel hop.


If I could simply swap in SDHQ's...I would in a heartbeat.

But I have a sworn oath to never touch those damn leaf spring again*.

if you are deciding between them...get the SDHQ's. disregard the $'s.


*or if la-z-boy markets that creeper that will stand you back up.

 

^^^Thought I read something about one of those two and adjustments?. . Thank you…

 

Worked with HP Tuners back and forth yesterday regarding my ECM. No luck so far. Waiting to hear back again on next steps.


Speaking of leaf springs and traction bars and all that. Any of y'all swapped the whole rear out to a 4-link setup?

 

Sorry to hear the ECU is giving you trouble still.

Who makes the four links you are talking about?

 

No one makes a direct bolt-on kit I don't believe but everyone I know that's deep in the automotive world (friend is an Engineer at Ford Racing for one) is telling me it's the way to go.

 

Oh. The one's I've seen are bolt ons but for dune running. If you find a bolt on kit I would be interested in looking at the specs. What I'm really interested in is a bolt on lowering system that can go back up to normal height for offroad/towing. Lowering springs and bags wont work for me. A company makes them for Fords but it is pricey; not sure I'm sold on the implementation either.

 

Nice and easy to find anything imaginable for a Ford. He's been showing me all sorts of sweet stuff for them as well as the Chevy Tahoe he just did a 5-link on.

 

So HP Tuners got back to me and let me know the PCM is dead and nothing can be done to fix it and I must buy a new one. Thankfully I already ordered one, so now we wait for it to get here.

 

So what is the proper protocol for flashing the ECU?

 

We should do a group buy, I'm down for it.

 

Is SDHQ a vendor on the site?

 

Damn it

I’d be in

 

I'm in.

 

Yes, @sdhq_offroad , we need to eliminate those wheel hops!

 

I'm digging they come with new u-bolts.

and

you don't have to jack with the leaf springs...

HP Tuners says not to flash with the battery charger hooked up, that goes against what I've experienced with other tuners, and I left mine connected.

 

That's interesting. All the tuners that use the HP for flashing, even on the Magnusson site, they tell you to plug it in to a battery charger while flashing. And everyone is blaming my issue on the fact that I didn't do so even though my battery was at 100%.

 

I thought that was odd. I've flashed tunes on 5 vehicles I've owned, and every platform has recommended (or demanded) that the charger be connected and the battery be fully charged.

 

ViktorG also stresses in his tuning video to hook up to a charger as well.

 

Went and got this bad boy... So I should be good now.
