Technical Which cable for multiecuscsn?

[Mickeypanda]

Hi all, hope you are doing alright?
I am having the, fairly common, idle and stalling problems with my 2011 Panda 1.2l 8v petrol.

I have used a cheap thinkobd2 scanner but I have doubts as to its accuracy. For example 11% accelerator pedal position sensor at idle? For this reason I would like to go down the route of multiecuscan but am bamboozled as to which cable to purchase. Can anyone recommend the correct one for my car please?

Many thanks.

Hi

Is it on a laptop.. or a phone

I use an ELM327 CABLE From laptop to car

The MES site has a supported vehicle list with all the info for YOUR CAR

Thanks for your reply varesecrazy. It's from laptop to car thanks. Are they plug and play or do they require 'tuning in' to the laptop?

The cable will need 'drivers' to communicate with Windows, then it should communicate with MES ok.

MES can sometimes be a little reluctant to communicate. Have a look at post #5 in this thread https://www.fiatforum.com/panda/352156-fiatecuscan.html for my solution. Wrote that a long time ago, seems to still work reliably.

11% at idle seems ok from memory. Old spark plugs can cause all sorts of running issues, even if they look fine. When I got mine in 2010, its idle was a little erratic, and moving away sometimes hesitant. Just new plugs sorted it. They appreciate new plug leads every couple of years too. Get NGK ones.

Hi Portland bill, thanks for your help. I'll look into your post, need all the computer help I can get...

My 5 series shows 0% accelerator angle at idle hence doubting the panda's 11% but your input is encouraging.

I've changed;
the plugs and leads

crankshaft sensor (due to code being thrown up)

A split breather hose from the air filter housing to below the throttle plate.

Checked the vacuum (20in Hg), seems fine and corroborates the MAP sensor values, albeit inverted

Cleaned the throttle body.

Checked voltage drop on earth straps and voltages from the alternator to the battery

Still got a 650rpm at idle and frequent stalls??

Next step is a compression test (should have done this first perhaps) to rule out anything major then down the MES route for more answers.
