Default Mems2 obd?

Quick question, is there a mems 2 compatible obd app. Borrowed a blue tooth plug and downloaded a few of the apps they connect to the device bit not to the ECU reading the web it looks like mems2 isn't OBD2 compliant, so is there an app I can try?

No there isn't. This is one major issue with the older setup.

The garage can use a program called testbook. This is very old skool technology.

If a fault occurs unfortunately it's a guessing game. Having a spare set of sensors is the only way I found to resolve problems.

I bought mems diag, which worked with mems1.9 and mems1.6, but when i fitted the mems2 vvc engine it no longer worked. Needs to be a Lucas ACR to read mems2, or rover testbook.

Andrew, when you say it's a problem with older systems does that mean there is an availability for the MEMS3 systems? If so what and where?

You can also buy and use PScan for mems2, I have used it on an early mgf to diagnose a vvc fault.

It's like an opensource testbook that is currently being developed. More expensive than obd2 but you can see a lot more with it, talk to abs and pas ecu's and program fobs etc.

Also Philip is a very helpful bloke.

mems3 is obd2 compliant so any obd2 reader will connect to it.

Rover / MG tend to miss out the signal earth on pin 5 of the obd plug in the car though so you may need to wire a bridge over to the chassis earth on pin 4.

Once done you can connect a bluetooth odb and use torque on android etc

I have this installed in my car as I like to have a reader connected and dont want to have to wait for an android device to boot, this comes on with ignition.

Yes, the MEMS 3 is cheap to setup for diagnostic repair. You buy an OBD2 Bluetooth unit from most motor factors or eBay etc. Usually under 20. Then download "Torque" app on a smart phone. There is a free version and another with more add on's which is 3. I just use the free version (not on Phoenix though as it won't work as stated earlier).

This works on most cars after about 2003. Useful to have as garage charge is vastly over priced on diagnostic report, never mind repair.
