Just been out in the garage to make some more tests, and my MS2 gave off that burning PCB smell, and when i opened up the cover a load of smoke.

I now have my stim plugged in and it all seems to be ok..... ?

Should i be concerned? It just so happens that my laptop gave me the blue screen just after i plugged the stim in. Could this have been caused by the laptop or vice versa?

When i got the smell, TunerStudio wouldnt talk to the eCU (Before the crash) and now it does., Mega tune always has. ??

Eeek!

Should i be looking to get rid of the unknown build MS2 and upgrade to MS2 V3?

Money is a bit short at the moment, but i should be able to get rid of the MS2 as it seems to be working ok now.

you could get it checked out by http://www.extraefi.co.uk/

Not cheap, but should sort you out, and he knows his stuff.

my money is on burnt out ignition drivers. if it turns out to be the correct fit bip232's as a replacement

try the stim see what isnt working then get the multi meter out with the manual and test each component in the circuit of the thing that is broke. all the component values are in the manual so it should be pretty simple to find the cooked part.

Whip the lid off and take a pic. If there was smoke it shouldn't be too hard to spot what went pop.

I'd also lean towards the ignition driver(s). The VB921's have a habit of letting the smoke out if they're left powered on with the engine not running. I supply the ignition coil +12V from the fuel pump relay to stop this happening.

If you do decide to replace the ignition drivers the Bosch BIP373 are a pain to get hold of.

What were you doing when it went smokey?

Photo, nice and hi-res, might allow someone to work out where the smoke was getting out.

And then fix it with this

Lol, ive already got some of that thanks Dave!

As in my original post;

I have taken the lid off
There is no apparent damage on top or underneath

I was calibrating sensors using the Thermistor Table Calibration tool when it happened.

Check the operation of every section of the circuit - go back through the build instructions and check each bit as you go. If smoke has been released it's usually very obvious what from, to the trained eye.
