Thinking about adding oil temp and fuel pressure gauges. I tow alot all over the states and local so do you guys recommend anything else I should be monitoring or if the fuel and oil isn't really necessary let me hear some input I'm rolling up on 150k miles on a 2001 and almost cried when I read the post with the same year motor that blew so would it be worth it to swap in some new rods or is it a coin toss when it goes? Thanks in advance for your advice.

 

I think fuel pressure is a good one to have. I think oil temp is nice to know if you have high HP mods but I'm not sure exactly on that one...

As for the rods....if it ain't broke, don't fix it. No sense in worrying about something that isn't likely to happen to your engine.

Have a safe trip!

 

I thought 2001 had the cast rods?

 

I just installed some additional gauges in my truck, fuel pressure, oil pressure, water temp, oil temp, HPOP, and volt gauge. The fuel pessure gauge will let you see if you are starting to have pump problems before it's to late and your oil temp normally will run about 10* hotter than watertemp. I wouldn't worry about rods too much unless you want over 400HP, that being said tuning is the key. Also remember that these trucks stock would dyno 180 to 200HP and good tunes will get you to 300HP + or - and a set of stage 1 injectors will keep you at around 375HP. I'm not worried too much about my PMR motor.

 

You didnt post anything about your truck, this would help us narrow things down for you. List any and all mods you have done to your truck and well recomend what we think. If you have a tuner egt is a must! If its bone stock you shouldnt have too much to worry about, in that situation gauges are just a nice thing to have to know whats going on.

 

I have trans, pyro, boost gauges, 5" exhaust, air intake, frx, overboost regulator, dpp chip, ww, transcommand, foil delete, zoodad

 

Like you said I kind of just want to know what's going on at all times with my truck

 

Never go wrong with gauges. there is nothing wrong with knowing what is going on under the hood!

 

Fuel pressure and oil pressure is what I would rather see than oil temp. From what I have seen oil temp and water temp will tell you similar stories, unless running big oil and higher HP.

To kill multiple readings at once I ordered an Aeroforce Interceptor Scangauge. I also ordered their add on sensor kits for fuel and oil pressure (PCM doesn't monitor them). This single gauge will now allow me to see multiple inputs in one spot. You can only view two at a time, but you can set it up to scroll through the different parameters too. May be something you look into. Cost is not cheap, but when I looked at installing separate fuel pressure, oil pressure, HPOP pressure, and oil temp gauges it was a better deal.

They were on back order, but they are beginning shipment this week.


On our PSD's it runs these parameters (adding the sensor kits will add the fuel and oil pressure) , along with reading codes and performing the CCT and Buzz Test.

(Bold ones indicate the ones I wanted the most)

1. INTAKE AIR 2- Intake Air Temperature taken at the throttle body inlet
2. COOLANT TEMP 2- Engine Coolant Temperature
3. RPM 2- engine Revolutions Per Minute
4. MANIFOLD PSI 1- Manifold Air Pressure (psia) for voltage based MAP sensors (mid 1990’s trucks).
5. Manifold PSI 2 – Manifold Air Pressure (psia) for frequency based MAP sensors
6. BOOST 1 – Boost Pressure in psig for voltage based MAP
7. BOOST 2 – Boost Pressure in psig for frequency based MAP
8. MILES PER HOUR 2- Miles Per Hour
9. TRANS TEMP 1- Transmission Temperature for 1998 and newer trucks
10. TRANS TEMP 2 – Trans temp derived from the trans temp sensor voltage for 1997 and older trucks.
11. TRANS VOLTS – Transmission temperature sensor raw voltage.
11. RUN TIME MINS- engine run time since last engine start. Can be used as a trip timer.
12. BATTERY VOLTAGE- Alternator/battery output voltage
13. PULSE WIDTH- injector pulse width in msec.
14. ENGINE OIL TEMP
15. EX. BACK PRESS – Exhaust back pressure
16. ICP DC – Injector Control Pressure Duty Cycle
17. ICP – Injector Control Pressure
18. INJ. TIMING – Injector Timing Deg BTDC
19. CURRENT GEAR – Current Transmission Gear

 

That looks awesome! Does it just plug into obd2?

 

Yes, that is how it reads the information. The sensors have to be installed and routed to the gauge, and they require a 5 volt power feed, you can use the one in the truck or you can add a 5 volt power supply for them.

 

Yea it seems like a good tool to have but it adds up with the sensors and stuff

 

Have you looked at the price of quality fuel pressure gauges? That is what made the decision for me, besides I was going to need more room for gauges. That would "force" me to buy more pod's or an F-650 dash.

 

I want one for #s 13, 15, 16 and 17 and the contribution/buzz test abilities.

 

Yea same here
