Rovergauge and ECUmate..............
Discussion
These are the differences:
ECUmate Lite is a simple fault code reader using the NA "OBD like not actually OBD" connector. Just displays a code number which you then use to look up in a chart to get the meaning.
ECUmate is a full blown diagnostic unit for the 14CUX using the Testbook connection. This gives access to the ECU internals.
ECUmate is standalone with a bright LCD display that is readable in sunlight. Plug in and use.
Doesn't need a laptop.
Displays realtime information with a faster update rate than Roverguage.
Data is internally timestamped to ensure integrity e.g. data from one sensor is not displayed with data from another but taken a second later.
Essential to avoid incomprehensible data.
Displays data in sensible units e.g. voltage values as well as percentages, bar graphs etc. Ideal for setting up AFMs and throttle pots.
Has throttle pot noise test built in.
Monitors the ECU during ECU power up to check for stepper motor initialisation and file pump priming.
Allows the stepper to be moved and fuel pump to be switched on.
Displays all fault codes with number that matches the original Rover fault code guide with text description.
Clears all fault codes.
Displays ECU idle mode state and contributory factors that control idle state.
Shows lambda operation.
Identifies tune resistor and associated map.
Works with any 14CUX eprom code including Mark Adams specials and others.
Mark actually uses one...
Has genuine Lucas TTS plug for reliable connection.

I'll add my 2p worth - I've never used the rovergauge but for convenience alone the ECUmate wins for me. Just plug in and get instant info and you can keep it in the car.
Only used mine a few times but its been invaluable helping to diagnose faults, if you have an RV8 then this should be in your toolkit. Before ECUmate I had a basic fault code reader, but the problems I had were not throwing fault codes, but were combining to create a few problems so it didnt help.
You still have to be able to interpret the results of course , but thats true of the roverguage and most other diagnostic computers.

Firstly both products have plus points. The ECUmate is a great product for keeping in your boot, as it does not need a laptop and Steve has already listed its other plus points.
Both diagnostics read ECU data in much the same way but some good points for Rovergauge is it will display multiple sensor data at once (without scrolling)- you could say compare live rpm values data against short term lambda trim to identify rich or lean running in a specific area. RoverGauge has the extra Lambda trim value for long term fueling which is good for a snap shot of how much base correction the ECU has to apply to get the mixture correct as short term on its own is only is only half the story. It also has a data logging facility, and an Eprom copy facility as its PC based. You can switch the sensor data to whatever units you prefer, and it will work with any ECU chip quite happily- it reads my Mark Adams chip without issues. The issue of slow reponse from the sensors has been resolved by making the display switchable reduce the load on the ECU data output, so no issues there now. As the software is PC based it can be upgraded as an when updates occur, that you cant easily do with a hard programmed test box. Of course there also the issue of price- a cable is lot less to buy or construct and the software is free- and that’s not a bad price.

Had a play with this today at Neil Garner's with my blue Chimaera. Mark, thanks for your time, I will be in touch next week to order one. I was very impressed.

Ps. I adjusted my idle screw when I got home, runs much better now.
I have them for sale in the classified under TVR-

Once you have purchased the Rover guage can you do anything with it ,like changing fueling etc or is it just for diagnostics ?
In theory I think it could be used as a mapping tool as it shows the fuel load values in real time- but you would need an Eprom emulator (about £200) to be able to alter the values to see the effect of a rolling road. Once you where happy with the map a new chip needs programming into another Eprom with a new check sum. Not sure if ecu will keep putting the data out at high RPM however.Gassing Station | Chimaera | Top of Page | What's New | My Stuff
