Not particularly interesting, but here's mine in action. I left the glass off and used the sunpro needle because I'm going to install a better gauge face. So this was just testing.

Not bad at all (IMG:style_emoticons/default/beerchug.gif) Is this running off a 5volt pulse?

Not sure. I'll have to look at how I have the MicroSquirt set up. I just plugged it in and it worked and didn't think about it again. (IMG:style_emoticons/default/wink.gif)

Hmmm. Now this has me thinking about gutting the rest of them and making custom faces too.

Great thread, and super helpful for those of us with other computers/engines installed.

For the price, it's a great project to do. I'm making another one of these this weekend, I'll update this thread with resistor values for a V8

I just finished a tach conversion for a V-8. R9 needs to be 243k ohms

Does this mean that the switch on the back is always removed/soldered as in the original instruction (first few posts) regardless of the number of cylinders? The R9 value sets the cylinder count?

Can you edit you original thread at the R9 step and put the values for each setup?

4- 499
6-
8- 243

Reviving from the dead due to awesomeness! This is great.

Is there a way it could be made for 2cyl motors? I have many motorcycles that would benefit form the ability to customize the gauges.

Thanks (IMG:style_emoticons/default/smile.gif) Yes, R9 can be configured from a 2 cylinder to a 32 cylinder. With that said, the variable of the equation would be the 914 tach face. In this thread, R9 was computed for the linearity of our 914 tach. New calculations would be needed for a different style tach face with the number of cylinders desired.

Hi Tim, Reading thru this post, did you decide to do this for folks that wish to send you their tach? (sent a pm but did not hear back). If so, I'd be interested in sending you my tach for the bounce mod, and conversion to six cylinder function. Thanks, Tom

Tim's service is great. I had him do high intensity LEDs in my gauges at the same time. He incorporates a cool circuit that controls the lighting as well! My gauges are set to gradually switch over from white to bright red as I approach the redline (I believe it's Tim's avatar). Makes driving at night a LOT of fun.

As a HVAC tech, I've been busy with this recent snap of cold weather. Sorry for not replying to your PM. Tom, you mentioned that you are installing a Honda V6 which I'm not familiar with the ECU's tach signal, it may be canbus. It could work but I can't tell you that it will with 100% certainty. You can do a quick test by purchasing the tachometer from AutoZone and temporarily wiring it. Set the slider switch to 6cylinder and try it. If it works, box up your 914 tach along with the Autozone 30 dollar tachometer, and I would be happy to put it together for you. If it doesn't work, simply return the tachometer to the part store (IMG:style_emoticons/default/biggrin.gif)

Thanks Tim, sounds like a good plan, hope it works, and I can send it along to you.
