I would like to put a comprehensive list together of the values for different RPM chips. ie: MSD's rpm chips.Since all RPM modules are based off resistance (ohms) all we need to do is use an ohm meter to read the resistance for a given RPM chip. Example only 2000 RPM=1.34 ohms. If we know the values of a given RPM it would make it easier for anyone with an adjustable module ( one with a small set screw you turn to increase or decrease the resistance) to tune without having to install and test in the car. You could also go to radioshack and buy the resistor and make your own. We could put this in the Tech archives for future use. What do you all think? I will put the list together if you guys/gals send me the resistance values for the following RPM's or anything in between.

3000=1.91 ohms
3200=
3400=2.21 ohms
3600
3800
4000=2.70 ohms
4200
4400
4600=3.21 ohms
4800
5000=3.58 ohms
5200=3.77 ohms
5400=3.95 ohms
5600=4.16 ohms
5800=4.35 ohms
6000=4.57 ohms
6300=4.88 ohms
6500=5.10 ohms
6600=5.20 ohms
6700=5.32 ohms
6800=5.43 ohms
6900=5.55 ohms
7000=5.65 ohms
7400=6.12 ohms
7600=6.38 ohms
7800=6.63 ohms
8000=6.89 ohms
8600=7.69 ohms
8800=7.97 ohms
9000=8.27 ohms
