If this has been answered before, just point me in the right direction but i wasn't able to find an answer.
I am up to step #50 through to step #65
So, step #50 says:
Use the Hall/optical/points input circuit, in step #50 of the V3 assembly guide, but:
Use a 1k resistor in series with the ignition input coming from the TFI. Do this by pacing a 1K Ohm resistor in the main board location marked "D2" (instead of the jumper you would normally put there)
Thats no worries, I understand that part.
When i purchased the computer i bought the MK Pullup Mod. This came with 1k resistors. Is this the one I use, or what was the purpose of getting this mod with my purchase? If its not, what wattage should i use, is 1/2Watt ok?
Then Step #56, this through me a bit:
Install the high current ignition driver circuit (step #65 of the V3 assembly guide). Note: do NOT install R57. Use a 100 Ohm, ¼W pull-up resistor on the coil output of the MegaSquirt® EFI Controller, and drive this directly to the TFI's SPOUT input. You can do this by connecting a 100 Ohm, 1/4W resistor from the IGBTOUT jumper on the main board to the via immediately below the "S12" making on the silkscreen (near Q19).
So, in these instructions specific to FORD TFI, it says to use a 100ohm 1/4 Watt resistor, but in the general instructions it says to use a 1kohm resistor.
My question is, do i following the instructions which say they are specifically for the Ford TFI, or do i use the general instructions and use the 1kohm resistor.
If i use the specific ones, is that resistor in the kit, and if not, is a pull up resistor just the same as a normal resistor?
Thanks for your help.

Re: TFI Ignition Set up
kieranl,
Use the TFI instructions here: http://www.megamanual.com/ms2/TFI.htm
I have no idea what a"MK Pullup Mod" is, you would need to ask your vendor about that.
Lance.

Re: TFI Ignition Set up
Thanks Lance,
Thats what I will run with then.
In this section
Use the Hall/optical/points input circuit, in step #50 of the V3 assembly guide, but:
Use a 1k resistor in series with the ignition input coming from the TFI. Do this by pacing a 1K Ohm resistor in the main board location marked "D2" (instead of the jumper you would normally put there),
Is that also a 1/4watt resistor?
Appreciate your help, i just got a bit confused when i thought I was reading conflicting info.
Cheers,
Kieran
