Have you got a solder sucker?

or some solder braid.

if you get in a mess stick the daughter board in a jiffybacg and send it to me,

I'll whack it under the microscope at work

If you intend on doing more soldering of that nature or even just redoing this one, a flux pen is very useful. And solder braid is essential.

solder sucker would be best. Although never used the braid stuff.

Or even try heating the solder then tapping the workpiece against the table to knock the molten solder off. Upside down of course.

speed didn't kill me, but taxation probably will

Solder sucker wont take that off, you wont get the seal to suck it up.

You need to clean the tip of your iron so its clean clean, no solder on it at all. Put a little bit of flux on the solder joint and heat 1 pin at a time, starting at the body of the IC and slowly dragging the iron away to the leg tip, dont what ever you do put pressure on the iron just allow it to drag under its own weight (assuming you are using a decent bench top iron not some behemoth monster!). Some of the excess solder will take to the iron hopefully removing enough to make a decent solder joint on one leg.

If you dont have any luck, PM me and we'll sort something as its what i used to do every day for 14 years!! (I've moved up the ladder now though lol)

think i have properly fucked this now :( got the solder cleaned off quite nice but the megasquirts 3 led just light up when its powered on it doesnt do anything else

Bugger.

Good luck trying to fix it. Not my field to offer advice.

I might soon be in a position to let you have a spare MS2 daughterboard at a knock down price.

Alternatively, you have a good excuse for an MS3 upgrade.

Paul if you do decide to get rid of your spare doughterboard let me know ill definitely have it
and good point on the upgrade, i didnt realise i could do that untill now

and cheers guys ill see how it goes

Brett, if you get the part and send it to me at work i'll change it for you, not being funny but saves risking anymore damage!

PM me if you want it done.

Brett,

I can certainly change the Processor for you,

But, I seem to remember that it needs some form of boot code loaded in before it can e programmed which is a bit specialized for me, I might be thinking of the MS1 processor though.

maybe Jean can enlighten?

You need the bootloader code and a BDM to program a new CPU.

I think that James Murray (jsmcortina) can repair and reprogram the CPU on an MS2 card.
