Resister
I brought a LC-1 from Bill and recieved it today.
When on the phone to him he said that I would need to install a resister inline when using with a Mega squirt.
What size do I need and where is the best place to get one?

I read (can't remember where!) that only the earlier LC-1's needed this resistor, and the current ones don't. Haven't fitted
one to mine with no ill effects so far.

When you know what size you require, Try Maplin's
If it doesn't fit MODIFY it!!

Copied from the DIYautotune website :-
Here are the two things you'll want to cover that AREN'T mentioned in the QuickStart guide:
Ground the LC-1 and the MegaSquirt together. This is to prevent a voltage differential and will ensure accurate readings.
THIS STEP IS ONLY ON LC-1'S IN THE YELLOW/BEIGE BOXES, NOT THE BLUEBOX LC-1'S: Use a 470 ohm, 1/4watt resistor in between the analog
output of the LC-1, and the o2 input of the MegaSquirt. So you'll wire the analog output from the LC-1 to one side of the resistor, and then
you'll wire the MegaSquirt 02 input to the other side of the resistor, forcing the signal to pass through it.
Blue Box LC-1's (started shipping around mid-June '06) have an updated DAC that does not require the 470 ohm resistor when used with
MegaSquirt. Another way to identify if you have an LC-1 with the updated DAC is the serial number for the LC-1s with the DAC update are LC11188 and
above and all LC-1s with a serial number that start with CLC.
Geoff.

If unsure, you can drop Bill a text on 077884 32735 and ask directly...
