Considering Engine Monitoring Device

[dieselshadow]

I’m looking at the CTS2. It has a nice mount and looks like it’ll monitor lots of stuff. Right now my truck is stock with no performance upgrades and have no desire to do any in the future as well.

What do you use? Do you like it? Pros and cons? Would you recommend what you are using?

I have the Insight CTS2. It's ok, and I'd probably rate it higher if I didn't have experience running the Touch and MM3 from MADS. That being said the CTS2 does it job as a non-tuner monitor.

The program to change the background photos is glitchy, slow, and frustrating but works in the end... just takes a full cup of coffee or beer to get it completed.

So I would recommend it if you aren't wanting something that is also a programmer.

I like mine. I have EGT off OEM one downstream of turbo, got a free EGT probe for it, but haven't been able install yet. I show RPMs because digital is easier to read, I have gear and TC lock, fuel gauge as percent and low warning at 1/4 tank. I have all maintenance items oil, air filter, fuel filters etc loaded reminders in it. Has a few options for appearance, gauges. Bought mine on Amazon.

I unattached my OBD2 connector and tie wrapped under my dash. I was a feared I would kick or damage CTST2 connector.
I'm speaking off the top of my head so there are other things I me be leaving out as my 5500 isn't my daily driver.

I have CTS2 as well and love mine. Still using suction cup mount for now.

I have one in my 17 with the a pillar mount. Does what it says it will do and so far so good

On my 01 I had an ez that lasted many years and miles then later a juice with attitude that also had many miles and years on it at least in my experience the edge products have held up well for me.

Not sure what functions you want to monitor but have you looked at the SCANGAUGEII? Small unit displays digital value for four user selected readouts. Plugs into OBDII.

I've run one on my VW TDI for years and just moved it to my CTD.

I really liked the display and interface that I got with the EDGE CTS and CTS2. Since i was using EFI LIVE (Autocal) i used the Insight versions of the CTS's. What I didn't like was the cost to add each additional Gauge such as EGT, Boost and Fuel as you have to purchase kits and adapter cables so you can daisy chain them in line which is convenient in the end.

I think in the end to have my CTS2, Boost, EGT, Fuel pressure and then Trans and Diff gauges it cost me almost $1,000 when said and done. I eventually started to have display issues with the Edge so I sent it in for repairs, Pulled everything from the truck and sold it all and recouped almost all my cost and then went out and bought Auto meter Z-series boost and EGT and haven't been happier.

I think that you can get to a point where you are trying to watch too much for no reason, so I tried to cut back on that so i can focus on driving.

All just my .02

Friends,

Popped into the 5500 to show my Edge monitor:

I got the pillar mount.... looks almost factory. There is one visible screw I painted to match the color. It has preset limits, and I changed a couple. And you can do data logging with it if you want.

EDIT: Sorry not a good pic of housing.... I'll turn on shop overhead lights and post again.

Cheers, Ron

No engine load? I really like seeing % load.

 

[Wiredawg]

No engine load? I really like seeing % load.

Stopped for lunch, putting shocks on the LRE. Not the originals but possibly 2nds.

I did a quick search and did not find a gauge that measures % engine load, except for boats. Please share if you find one.

Cheers, Ron

Ron,

I'm running the SCANGAUGEII right now, recently installed from VW TDI. I don't remember seeing % engine load but it does have a HP function. I run that on my display for grins and it varies from idle to cruise and towing rather surprisingly. Like this AM, started truck waiting from SWMBO to get in and it showed like 2 hp at idle. That's different don't remember seeing any HP display at idle. Oh yeah, it's chilly outside at least for us like 40 deg. I think that was the HP just to spin the input shaft on NV5600 this am?

There is an engine load, guess y'all are pushing me to be smarter.

PRETTY cuel!

Cheers, Ron

 

[BarryG]

on my edge insight cts2 it does have the parameter for engine load. This unit is on my 2017 while it may be different for a later year it is available on my 2017 again unsure if the part number and programming are the same for a later year

 

[GCroyle]

I was taught Torque rules but customers only knew HP and % is how much of what? 90% of my VW 1.9L TDI ain't squat compared to 50% of my CTD.

That's what happens on rainy nasty days. Yeah get crappo responses.

I need a few Coleman lanterns to tinker on. These were from last month. A 201 11/79 and a 237 10/57, both run kero only.

Engine load = Throttle position?

 

[AH64ID]

Engine load = Throttle position?

Kinda, but much more than that as it's not liner between TPS and Load... as well as TPS is 0 when using cruise control.

Basically it's the percentage of fuel being delivered, so you know how hard the engine is working.

 

[Wiredawg]

Friends,

I found how engine load is calculated by Googling it and after reading the answer, then realized this info is available on our trucks. I alsot made me look at the /edge monitor menu AND voila, it was there.

So, throwing a WAG at it what the relevance of knowing engine load, I'm guessing percentage of load is relative to the vehicle the data it is being derived from and based on the info I'm posting below, is calculable. It may also help if you know what 100% TQ your truck actually puts out. What we do with the engine load number is another thing.

FYI: I'm a tad GRUMPY today as I installed 3 new shocks on my LRE and the last one had ONLY a single washer in the parts bag, missing two rubber bushings, another washer, and a nut. Getting another new shock tomorrow.

Here's what I found today if anyone is curious how load is calculated:
​

There are two types of LOAD specified in SAE J1979

One is CALCULATED LOAD VALUE and the other is ABSOLUTE LOAD VALUE.

Calculated LOAD Value (PID 04)

The OBD regulations previously defined CLV as:

(current airflow / peak airflow @sea level) * (BARO @ sea level / BARO) * 100%

Various manufacturers have implemented this calculation in a variety of ways. The following definition, although a little more restrictive, will standardize and improve the accuracy the calculation

LOAD_PCT = [current airflow] / [(peak airflow at WOT@STP as a function of rpm) * (BARO/29.92) * SQRT(298/(AAT+273))]

Where:

STP = Standard Temperature and Pressure = 25 °C, 29.92 in Hg BARO, SQRT = square root,

• WOT = wide open throttle, AAT = Ambient Air Temperature and is in °C

Characteristics of LOAD_PCT are:

• Reaches 1.0 at WOT at any altitude, temperature or rpm for both naturally aspirated and boosted engines.
• Indicates percent of peak available torque.
• Linearly correlated with engine vacuum
• Often used to schedule power enrichment.
• Compression ignition engines (diesels) shall support this PID using fuel flow in place of airflow for the above calculations.

NOTE Both spark ignition and compression ignition engines shall support PID $04. See PID $43 for an additional definition

of engine LOAD.

05 Engine Coolant Temperature A –40 °C +215 °C 1 °C with

–40 °C offset

ECT: xxx °C (xxx °F)

ECT shall display engine coolant temperature derived from an engine coolant temperature sensor or a cylinder head temperature

sensor. Many diesels do not use either sensor and may substitute Engine Oil Temperature instead.

Absolute Load Value (PID 43)

The absolute load value has some different characteristics than the LOAD_PCT defined in PID 04 This definition, although restrictive, will standardize the calculation. LOAD_ABS is the normalized value of air mass per intake stroke displayed as a percent.

LOAD_ABS = [air mass (g / intake stroke)] / [1.184 (g / intake stroke) * cylinder displacement in litres]

Derivation:

• air mass (g / intake stroke) = [total engine air mass (g/sec)] / [rpm (revs/min)* (1 min / 60 sec) * (1/2 # of cylinders (strokes / rev)],
• LOAD_ABS = [air mass (g)/intake stroke] / [maximum air mass (g)/intake stroke at WOT@STP at 100% volumetric efficiency]

• * 100%. Where:
• — STP = Standard Temperature and Pressure = 25 °C, 29.92 in Hg (101.3 kPa) BARO, WOT = wide open throttle.

The quantity (maximum air mass (g)/intake stroke at WOT@STP at 100% volumetric efficiency) is a constant for a given cylinder swept volume. The constant is 1.184 (g/litre 3) * cylinder displacement (litre 3/intake stroke) based on air density at STP.

Characteristics of LOAD_ABS are:

• Ranges from 0 to approximately 0.95 for naturally aspirated engines, 0 – 4 for boosted engines,
• Linearly correlated with engine indicated and brake torque,
• Often used to schedule spark and EGR rates,
• Peak value of LOAD_ABS correlates with volumetric efficiency at WOT.,
• Indicates the pumping efficiency of the engine for diagnostic purposes.

Spark ignition engine are required to support PID $43. Compression ignition (diesel) engines are not required to support this PID.

Pretty interesting, Hugh?

Can you monitor REGEN on the CTS2

 

[Wiredawg]

Can you monitor REGEN on the CTS2

Yes. I haven't played with it to see how much info is presented. There are a few threads discussing regen, how often, etc.

Cheers, Ron

 

[Wayne M.]

Ron, I believe the short and long fuel consumption calculations are based on some of these load values.
