Can anyone make me custom chips ? Need 2900, 2800, 2700

I don't want to constantly change my adjustable. Please lets me know and how much you would want for them. Thanks

idk what ignition you are using now, I guess an analog 6al from msd. Have you considered going to a programmable one? I use a programmable 6al now in my super gas car and it's really easy to use and infinitely adjustable.

These are very easy to make yourself. Simply measure the resistance of the variable limiter chip for the various RPMs you want, and then shop Amazon or an electronics supply store for the resistor values you need (you can probably pickup a pack of standard-value resistors for $10 - $15). 1/8 or 1/4 watt resistors are fine with 5% (or better) tolerance. The plug connectors can also be sourced on Amazon or at electronic supply outfits; they're not critical.

Once constructed, you can cover them with heat shrink tubing to keep contaminants out of the circuitry.

Here are all the ohm values is case you didn't want to measure them all yourself.

If you have several 3000 chips, measure them with an Ohm meter. The one with the least resistance will probably come close to a 2900 or even 2800 rpm.
