OK this might seem like a stupid question but I have just received a new chip from Gabro and have a quick query.

Which way round does it go?

I am assuming that when I have the unit with the plugs downwards the writing on the chip should be the right way up.

Does it matter?

should be a notch at one end of the chip that corresponds with the chip carrier. Take no notice of the way labels are put on. The chips are standard EPROM jobbies.. The only special thing about them is the info they hold

Didn't notice that. So if the chip has gone in and has sat snugly down all the way round it has to be in the right way?

no.. it'll fit either way.

chip looks a little like this

socket should look a little like this

Both the chip and the socket have a notch in one end of the chip. These should go together. If you put the chip in the wrong way round and put power to it (connecting the battery could be enough!) you'll bugger the chip.. No if's, no buts..

Ping?

Now you got me all worried

So much so that I have just been back out to the garage in the cold to take it all apart again to check which way I had put it in but god am I glad I did as it was in the wrong way wound. Just got to hope now that it starts alright in the morning as I don't think the neighbours would appreciate me testing it now!

if you didn't turn the ignition on when you fitted it, chances are it's ok. These chips are pretty hardy, but you can pop them very very easily. Inside that chip is a very small circuit which requires all the things a normal circuit board needs.. including power supply. If inserted the wrong way round and powered up, you could send power up the wrong circuit and blow it.. not good..

fingers crossed for you...

Thanks for the advice.

Didnt turn the ignition on literally just fitted it and walked away. Too llate for too much loudness.

Heres fingers crossed for the morning.

pretty sure you'll be ok..

At least there's the old chip to fall back on

Should be OK as long as you kept your grubby paws off of the pins and avoided zapping it with static

Well got up to go to work this morning, pushed the bike out of the garage and turned on the ignition full of trepidation as to what I had screwed up last night and....





it fired first push as usual. The chip seems to have made a bit smoother and has given it a bit more shove fronm about 6k onwards so I guess the next step is to take Griff up on his offer of a run up to Hull to get the thing balanced and checked over so if there is anyone else up this neck of the woods that fancies trying to organise a day of it then let me know and I will try and arrange it with Griff.

Excellent. Glad it works. Nothing beats that massive feeling of relief after something working when you think you've ballsed it up..lol.. nice one.
