As denis747 says, I'd be surprised if we were able to make changes using this, you'd need a proper T4 machine for that. It's more for diagnostics - I'd imagine it'll show similar info to the "Torque" app which I used to use on my ZS (and still use on my mum's R45) which connects via Bluetooth to an ODB reader, you can use it to read and reset diagnostic codes, monitor RPM, coolant temperature, and so forth.Hmm, I have a look at this, read the blog and it is most interesting but I don't understand any of it because Im a modern illiterate! Im not joking. Does it enable you to make adjustments to your engine settings etc? Thanks for your time. Chris.
Many thanks, rover 64. Since posting, I have managed to run this app on my Windows 7 laptop through an Android emulator called Andyroid. None of the other emulators I tried could pass through the usb data. I am very impesssed with it, as I am with a Windows app called MEMS Diag 1.6, but as the name suggests, it has been developed only for MEMS 1.6, because the developer lives in the US and only has access to his own Mini SPi.http://forums.mg-rover.org/showthread.php?t=784234&page=2
I have had this working really well on the 1.9 on my 620ti 1997
On my Rover 100 SPi, MEMS 1.6, I looked at the "unknown" tunable, which Pawel, the developer, suspected was related to ignition advance. At first, by taking measurements with the car stationary, I found there was no effect on ignition advance, but when Pawel suggested that it might only take effect under load, I tested the car whilst driving up a hill using different settings (increments) for that "unknown" setting, and, it does, indeed, alter the advance curve under load. For example, at around 3000rpm (second gear up hill)No I haven't tried any of the tuning features as yet but hope to when I get time. First take down all the Base settings so I can put them back if worse.
It would be good to find out what the parameter settings were when the car left the factory but can't seem to find that info no matter where I look.
Apologies - I've now set up e-mail alerts. Sorry.Did you feel it improved the driveability or give any improvements in Performance?
I tried accessing the mems 1.6 on my 820 turbo yesterday after buying all the relevant leads and connectors but couldn't get it to connect with the ecu using the colours identified, what colour wires did you use on yours martin.
.hi martin, interested to know how you got this working with andyroid, have you got a link to the forum thread? i'd be very interested in setting this up and also dont have an android device!
Hi Martin,Apologies - I've now set up e-mail alerts. Sorry.
Mine is a MEMS 1.6 with a 3-pin connector so I used the instructions at http://alum.wpi.edu/~colinb/mems_interface.html. I expect you have the later connector.
If yours is a 3-pin, I'll send you photos, otherwise Pawel, the developer of the app, is very good at replying to questions. Perhaps your Android device can't cope (see below)?
And yes, advancing the ignition to the 116 increments did improve drivability, all the more so when compared with the car retarded to 140! And there are graphs on Pawel's website showing torque and power curves for those 2 settings http://memsdiag.blogspot.co.uk/ That timing tunable advances the timing map when the manifold absolute pressure (load) gets to around 65 kPa.
I'm really pleased you not only sorted out the problem but that you are very happy with the app. When you think that all the app developer has to work on is a stream of binary data, the mind boggles. They then have to do a lot of detective work and drawing of graphs to try and relate all those ones and zeros to something meaningful such as idle speed adjustment.Hi Martin,
Yes i did get the 1.6 working ok the problem was my poor soldering on the signal wire, so i can successfully talk to all my rovers. As yet i still havent tried the tuning elements due to too many things on and with winter fast approaching this will now be a spring/summer project now i have comms.
My android devices are sony experia and have no issues at all but do understand on lesser make equipment this may causes problems.
As you have said Pawel is very good on the tech support and has developed some upgrades which i am still to access although have updated the software. I did mention to him during emails about ABS and SRS functionality and hopefully this is something he will develop given time.
A very worthwhile app and tool with very little outlay.
