Ultragauge / OBDII 2 two ecu gauge gauges

[Cameron McPherson]

Pardon the thread title - I tried to include as many keywords as possible to aid with searching.

I'm thinking about getting an UltraGauge for the Legnum. It's basically a screen that plugs into the OBDII port and then gives you a whole bunch of info.

I have a few concerns about this, mostly because I have very little knowledge or experience with ECUs, datalogging, OBD ports etc. I'm hoping you guys will be able to answer some of these concerns.

Firstly, has anyone used this particular product on their VR4? I saw someone mention it on the FB page the other day, but thought we should go over it on the forum instead.

The product totes itself and a ready-to-go 'plug and play' product - is this the case? I'm keen to do it if it's as easy as it sounds, because it's relatively cheap and simple. But if it starts to get complicated I won't bother.

I assume this just gets data from the ECU, which gets the data from factory sensors - much like a tuner would get when tuning? So I'm hoping some people who have experience with tuning can let me know what type of data imputs are available without having to add sensors etc.

I'm keen to use this mainly as a AFR and boost gauge (I already have a boost gauge, but if I can consolidate it into this then that will save space). I'm confident it should be able to get both of them, even though the AFRs are from a narrowband sensor as opposed to a wideband.

If both of those will work with the plug and play device, it will be worth the money to me. But I'm also keen on seeing what else would be available. Coolant temp in Celsius, fuel pressure, exhaust temp and maybe some sort of intake temp would be of interest to me - but I have no idea what sensors the ecu has from factory.

ODB2 won't work, our vr4's use the MUT protocol

 

[douwboy]

Reveltronics UT comp pro. I just got one installed in my car. Still got a few things to hook up but works really good and fits in the clock display.

 

[Cameron McPherson]

So reading up a little more on MUT and OBDII.

Am I getting this right - our cars have an OBDII plug, but the 'program'/protocol/software is MUT? I think sometimes this is called MUT ober OBDII?

So while our cars have an OBDII port, noobs (like me) could easily make the assumption that OBDII products would work. I can imagine the frustration of everything plugging in correctly, only for the devices not to talk to each other.

Seems like the best way would be to search for a product that supports MUT over OBDII. But these will likely be rarer and harder to come by because it's less common.

Also shout out to Mitsubishi for using something that isn't the industry standard.

 

[UNARMD]

Basically yes, we use MUT protocol through an OBD2 socket. It is a major pain in the ass in my opinion. It really hurts my feelings tbh.

If I recall, US cars were forced to support OBD2 after '96 but wherever they weren't forced to do it, Mitsubishi did not use the industry standard protocol.

 

[pretzil]

Ugh, this is nothing that couldnt be achieved by a glovebox full of ebay gauges Cameron...

 

[Kaldek]

My own long term approach to this is a set of gauges, hidden away and all sending analogue 5v signals to one of those little car computers everyone has been fitting.

 

[Cameron McPherson]

Yeah I spoke with Paul Gatt and he's got this gauge in his 3000GTOStealth, because he's using a USDM ECU. As far as I'm aware the VR4 8th gen wasn't ever sold in the US, so there wouldn't be any OBDII VR4 Ecus. Maybe the non-vr4 ecus are the same, but that's still a lot of cost and effort. Remember, the point of this idea was hopefully for $100ish I could grab something plug and play to eliminate a few gauges.

While I've always had plans for a few other gauges on my centre console, I thought if this was to work it'd be a cheap and easy way of consolidating a couple of gauges.

Guess it's not to be

 

[Nitephyre]

8th gen Galants were sold in America, but they only came with 4/6G engines, not 6A13.

So far there is 3 options for your needs
1. Use UTCOMP 3.0 Pro which i am running right now
2. Use Zada Tech which is very costly
3. Use techtom 100
4. OBD Key bluetooth. No guarantee that will work with Pre OBD2 ECU galant protocol, but report said its works with many pre OBD car. a bit pricey though.

5. Use android digital gauge offered by evoscan.


as for 3000GTO, it has 3 kind ECU protocol, OBD1, Pre OBD (hybrid) and the latest model has OBD2 protocol. so be cafeful to quote which GT3000 that will work with Ultragauge

 

[Cameron McPherson]

Have looked into UT Comp. I don't particularly care about the trip computer or fuel economy side of things. I was more keen on a product that allows me to display the the information like AFRs etc that the ECU is already getting.

 

[Kaldek]

I was more keen on a product that allows me to display the the information like AFRs etc that the ECU is already getting.

ECU doesn't see AFR. It's quite limited. You get:

• Load (airflow)
• Rpm
• Ignition timing
• Injector pulse width
• Injector duty cycle
• Current fuel trim
• O2 sensor voltage (narrowband - is not able to show AFR)
• Knock count
• Throttle position
• Coolant temp
• Air temp
• Road speed
• Idle Speed Controller steps

There's a few others but they're variants on the above. EvoScan includes a "fuel consumption" value but this is just a calculation based on injector duty cycle. If you wanted to see AFR and boost in the VR4 you need separate dedicated sensors. You *can* feed boost and AFR from dedicated gauges into the ECU on some spare pins, and then get that data out of the ECU (as the code to read the pins and store the data in RAM is still there in the ECU code) but at that point you may as well just send the boost and AFR data directly into a UTComp.

The UTComp also includes a fuel consumption calculator, and it basically works how EvoScan does except you tune the parameters as you drain and fill up the car so it can work out how much fuel is delivered for each injector pulse. This may sound totally inaccurate but it's actually how the fuel consumption code in an OBD2 compliant car works anyway - it measures injector pulses and has some calibration data in it which informs the calculation how much fuel is injected per pulse. This is unique to every model of car because they all run different fuel rail pressures, and the amount of fuel injected per pulse is a measure of the injector opening time and the rail pressure.

Lots of good info there Ed, thanks!

another option that might suit you is the ARK MFD

http://www.full-race.com/store/electronics/ark-designs-mfd.html

I have one that will be going into my legnum soon, the only problem is you need to wire it into the ecu loom rather than plug it into the OBD port.

Has some pretty cool features too, and can display up to 8 vehicle parameters at the same time.

How do we do that?

 

[thatjdmguy]

you find the ecu loom and splice the wires from the MFD into the correct wires in the ecu loom.
