Observations on first connection
Windows 7 home premium sp1
software loads and runs from IE, warning on file provenance ignored.
software doesn't run from desktop icon it asks for the pscanloader.
Connection OK .petrol. mems 1.9 for '97 MGF
No faults reported but none expected. I have a T300 but haven't had time to compare readings.
Checked the SRS, a bunch of codes cleared and not reappeared, is there a list of codes somewhere on the interweb?
Live data not working clicking a + brings values for most things but they don't update, running the engine doesn't make any difference. Clicking back at this point makes the software flicker repeatedly and lock up. Only closing and restarting will work.
Live data doesn't work on the T300 either BTW. the T300 stalls the car when using live data
I will play more tommorrow.

Live data doesn't work on the T300 either BTW. the T300 stalls the car when using live data Please connect the Internet and run pscanloader. Accept upgrade to version 03FA. This implements two methods of collecting live data. Live data 1 is the old method. Live data 2 is a new method which is closer to what a Bosch KTS does. This method has the potential for faster updates and appears to fix the issue with carlvk's ECU. However when this was originally developed two years ago it gave strange data with the engine running on a Lotus Elise. Live data 1 was originally what fixed that. Please could all MEMS 1.9 owners try both method 1 and method 2 on a running engine and feedback whether the numbers look sensible. Please try it one parameter at a time as well as many at a time.

Connected succesfull on my MGF '96, MEMS 1,9.
Live data1 and 2 tested, both are working fine but live data 2 looks a litle bit faster.
The only problem for me is that the interface loose connection during starting the engine.
Normaly i read and erase fault codes with ingnition on engine not running, then i start the engine and switch to live data, the connection stay active during starting.
I must say that this is my first time that i read out a Rover, so i don't now that this also with T4.
greets, Herman

Nothing more to add on the standard windows. Still working well.
But I'm thinking can the data be logged?. I would love to run and log this on a Raspberry Pi. I'll bet it would be possible to use the io pins on the PI to control stuff too.
hmmm.

Tested on my MGF 2000my mems 1.9 No error codes as expected Live data 1 & Live data 2 both working Ok As reported in earlier post Live data 2 does look slightly faster?

Works on my 1997 S1 Elise !  Have one reoccurring error: 5: Ambient air temperature sensor faulty Is this error there because the Elise doesn't have one ? Or does the Elise have one and do I have a problem ?

Connected to 2001 Rover 75 CDT using Windows 7 with latest updates.
I found this (below) but not sure what I was doing and not had chance to test again
I cleared the faults but hope they come back as I know I have an ABS fault.
As I say I am not sure what I am doing so please bear with me if this is nonsense to you, but if you know what it means then please reply.
I need to practice with taking screen shots as I forget exactly what I see.
Ken.
ABS number 04
Wheel speed sensor rear left incorrect signal.
24: Ring gear wrong number of teeth.
Then something like:
Suspect k Line short + v

I too have tried the PScan on my Elise S1 and it too comes up with the temperature sensor error. Maybe this is just peculiar to Elises. Car seems to be running OK. Been trying to find out if the Elise has one of these sensors or not. It does have an inlet temperature sensor (green thing on the manifold) but not sure this is the same thing. Anyone got any thoughts?

The ambient air sensor is,( if there is one), mounted in the engine bay to measure te engine bay temperature. If there is no engine bay temperature warning lamp in your dashboard and no enginebay ventilator to provide forced aircooling i assume that there wil be no ambient temperature sensor. You can also check pin 34 of the mems, if there is nothing conected than you don't have one.
I think that it is typical an MG(T)F thing.

Worked on my sons Rover 200 1.4 8v 1998.
Will have a further look at the live sensor info, but the error codes showed just
coolant temperature sensor faulty, don't know if it actually has one?
Will try to post some engine data when i have some and also found out how to attach screen prints to these posts..

Hi, Working well on Elise S1 '97, with linux version (Mint) I had some sensors faulty, but battery has been unplugged for 15 days. Engine running, I erased the codes, it's now all clear except error code 5 (wich is normal). I could not drive a bit to be sure that faulty codes were still real or not. Stats are moving as intended when opening throttle body. Coolant Temperature 69° Engine speed 980RPM Throttle valve position sensor 0.6V Intake air temperature 28° Ignition advance 10.0 deg Coil charge time 3.5 ms Oxygen sensor voltage 1.07V Battery voltage 13.8V Live data update interval 529ms Idle switch Closed Stepper motor position 51 Idle Speed deviation 30 RPM Intake manifold pressure 30 kPa Fuel temp & park switch intentionally ignored Yannick

Works well on my Lotus Elise S1 2000 year. Will post values up later. Got just one fault code for a temperature sensor that keeps coming up and won't clear. I understand that is because on the Elise, the sensor doesn't exist. Would be a good enhancement to be able to set the reader up to ignore this code for the Elise.

Hi All
I am interested in this reader for my Lotus Elise S1 March 2000 with MEMS 1.9. I have not bought one yet but have noticed the comments regarding peoples use and it seems to work OK. I have the Elise Service notes and in the section MN on the electronics the circuit diagrams for both the pre 1997 and post 1997 models show an inlet air temp sensor connected to pin 16 of the ECU. So is there a small issue with the reader if it reports a fault. Other wise it look like people are very happy with the unit.
cheers
Bob

I think for the next release I will make the program read a small text configuration file.
In the file customers will be able to define error codes which the software will ignore.
In this way I can keep the software "fully functional" but allow customers to modify the behaviour as they wish.

Hi Again
I note that there is some discussion in another thread re the 5AS alarm system. My March 2000 Lotus Elise S1 with a mems1.9 ECU has got the Thatcham Cobra 6422 alarm system. Will this interact with the Pscan unit OK?
I assume that as well as reading fault info the unit will, if require permit the resetting off the fault to clear the fault form the ECU
cheers
Bob

Received pscan unit this week. Running software version 412 on a Windows 8 Toshiba Netbook. Successfully connected to MEMS 1.9 on a 1999 Rover 200 1.1. No problems, error codes and live data all functioning as expected.

John D,
Did you get live data working on your MGF? I tried connecting to a P reg MGF with MEMs 1.9 at the weekend and could not get live data to work.

Hi Nigel,
no I never got it to work, i'm waiting for phil to sort the programing on rob bells MGF which has the same problem.

Just received my PScan today.
Tried to record live data but it said communication error.
I asked me to turn off the ignition and start again.
Followed the instruction but still no luck.
Is there an instruction available？
My car is a 97 Lotus Elise.

My car is a 97 Lotus Elise. Please can you try to access live data with the ignition switched on, but with the engine not running? I suspect that this is the same problem that other customers have been having with the MGF. The good news is that Rob's MGF is now at my house which gives me a good opportunity to see what the problem is.

I tried looking for the ECU part number from the ECU in my Elise but seems no label on the ECU
Connected the device to PC and the 16 pin socket, click the live data page and click on the "+" on the left hand side of the screen, I am able to see the data.
Several items with invalid value.
A. Fuel temp
B. Oxygen sensor frequency
C. Oxygen sensor duty cycle
But the screen also mention oxygen sensor status is OK
