Any Continuing Issues with SCT Livewire???
I have a 2004 Ex Limited 4x4 6.0 and am getting the body lifted to put in head studs, new gaskets, heads decked, machined and o-ringed, MBRP exhaust, aftermarket turbo drain, bulletproofdiesel EGR Cooler and Oil Cooler, relocated coolant and oil bypass filters, EGT port in exhaust maniforld ... and so forth.
My question is, I would like to put in the SCT Livewire in a pillar mount, and get some custom tunes for the EX from Eric at Innovative. I have read in the past on this forum tho, that there have been problems when the Livewire first came out. Have these problems been resolved with the newer versions / updates and so forth? What has your experience been with the Livewire? Is there anyone still running one?
Thanks! I really appreciate the feedback and all the advice and even opinion from this forum!

please can someone tell why people put the egt port in the manifold? I personaly dont care what the exhaust temp is comming out of the manifold. I would much rather know what it is comming out of the back of the turbo.

I would not spend the money on o-ringing the heads. Lots of trucks pushing high horsepower are fine with stock or stock-like gaskets. O-rings can cause a lot of reliability issues down the road and make it so your heads can't be returned as cores.

Actually, no you don't want to know what it is going after the turbo, after the turbo it's cooler temps(usually around 200 degrees). In other words, everything before the turbo can be experiencing hotter temps and thus increased chances of doing destructive work to your engine. You gauge might be reading 1100(which is fine for our engines), but since it's post turbo, your engine might be dealing with 1300 plus temps and that's not good if held there for a long time.
As to issues with the LiveWire, the main issues that I still hear about are to do with the screen freezing and stuff like that. Some do it, some don't. It's a 50/50 kinda thing.

I was wondering the same thing as to why everyone wants EGT in the manifold.I've been working on class 8 trucks for about 10years and have never seen in manifold.Always about 2" after turbo.Even on the older mechanical engines they were after the turbo,and trust me those engines were easy to burn up if you didn't pay attention.

to correctly watch egt to prevent a cyclinder from melting you would need one for each cyclinder. in the case of a more advanced engine I would look more towards trims (6.4 and the like) in a 6.0 there is nothing to really watch and the reading from one bank will not clue you in on the other bank. However a if you were to have agauge for eot,ect and cooling system pressure might get you there.
In fact what im seeing come through the shop makes me wonder if hooking a pvt to a gauge to moniter cooling system pressure would be worth it.. adding a 300 sensor may pay off in early egr and head gaskets warning signs.
Im still much more in favor of what the hd truck do wich is moniter with in 10" of the outlet. The reason for knowing the manifold temp preturbo is somewhat valid as if the temp is higher there it should be higher on the outlet as well.

How accurate can EGT being monitored on either passenger or drivers side manifold be??What would happen if one cylinder opposite side of prob was running cooler??Iam not sure about the PSD but on some bigger motors C15 cat 60 series Detroit you could run on 5 injectors out of six and not know it, ive seen this happen before.Generally what are the temp differances between mounting prob in manifold or aft turbo.Just curious.How close is the prob being mounted to the exhaust port??Sounds like if you wanted to be really fussy and monitor properly you would want to put probs on each manifold??With two gauges to monitor each bank?might be easier to monitor cylinder temps.

I know for a fact that it is cooler on the outlet, because when I first did all this, my egt probe was mounted after the turbo. When I found out that's where they had it mounted I swapped it out of there and put it in the manifold. I was running the same tunes, so I had something to compare it to and there was a 200 degree difference for me. I was easily able to peg out a 1600 egt gauge, where I wasn't able to before. This was just running tunes by the way, before the injectors and turbo.
