Great Writeup
iN terms of the pressure gauge on the dash i did a mod like this on my old 95 Explorer where i insatlled a real pressure sending unit ment for an old 80's mustang into the factory spot where the pressure switch was and plugged it into the factory wire. Then had to remove the dash and remove a resistor behind the gauge and carefully solider a jumper in instead. It worked great. 2 months later crashed the truck :-(

i am interested to know if anyone has done this on the super duty yet. i have not had my dash apart to even look yet.

Thanks

 

TSB 09-24-3 adds a few items to consider with regards to readings:

Wrench light comes on and defuel at 28.6 psig boost (I am told this specific value is from the PC/ED manual).

FICM low voltage detection monitor - DTC P0560 stored and wrench warning lamp illuminated when the PCM VPWR PIDS is below 10.25V for 60 seconds or below 9V for 4 seconds.

This TSB is for 2005-2007 engines (and 2008 - 2010 E series).

 

thank you Bismic. Question now to you. If your running a tune then did the person writing the tune take this into account (the boost pressure) and write something around this? I know a bit off subject.

 

Good question jetact! I certainly can't answer that, but I was wondering it myself.

 

Maybe Matt or Eric will chime in if they see this. I would like to know as I have tunes from both. Matt said on his street + to see where the boost was and if not over 30 to go to ++. I have been up to 28 and am thinking about leaving it. I do have studs but just not sure and now with what you said about the defuel I would love and answer

 

This TSB came out around March of 09. If you have not had Ford do any flashes after that date, then you probably don't have it.

 

No I am running an older flash so I must be ok.

 

What can i use to check all these temp, would a scanner or programmer read this stuff while driving or do i have to hook up some guages seperately. sorry if this sounds stupid but i really want to know whats going on under the hood when the truck is towing or plowing.

 

Many of us use an OBD monitor to check temps. Edge Insight, Scangage, etc. These can monitor all the temps in Bismics list in the first post, with the exception of fuel pressure. Also, Edge Insight can do EGT, Scangage cannot.

 

I use SG II and am monitoring TFT. Is the poor operation of the OE Temp Gauge described above because of the Gauge itself or what?

In other words, is the data the OBD is sending to my Scan Gauge sufficiently accurate for monitoring TFT?

Thanks

 

Yes, your Scangauge will read accurately the Trans temp. The dash gauge never moves once it is at normal on my truck, even when I'm towing.

 

The OEM sensor is excellent and will give accurate results. The dash gauge is buffered and dummied down by the PCM/cluster.

This seems to be true of all the sensors, except for the oil pressure, which is really just a switch. Ford even calls it a switch.

 

Thanks guys. This SG II is GREAT. I am monitoring Boost, ECT, EOT, TFT. Still trying to figure out Boost though. It only reads max of 17 and goes way negative when shifting gears.

 

When it comes to boost, I gave up. Can't get it to read properly. If you get yours to read right, pm me the codes you installed would you?

 

If you're using the built-in MAP gauge reading, subtract 15 from it to get "close" to what you're running for boost.

MAP is an absolute pressure reading; you can subtract atmospheric (14.7 psi @ sea level) to get boost. Of course that will change if you go up in altitude, but it's quick-and-dirty.
