So where is the best place to find a tach that will work and what am I looking to spend on it?

I got mine at dnr customs

So am I understanding correctly that the wiring under my dash for the tach will not make just any tach work? I was confused cuase I hooked up to that but I get no signal so no tach.:humm:
I've used 2 aftermarket tachs just fine from my factory connector. My truck is a 93. I had to set each tach to 4cyl mode to get accurate readings. I am thinking the chrysler ecm sends out signal to the tach as if it were a 4 cyl for who knows what reason but it works! |

You will get a reading but it's far from being accurate! I did the same thing with my Auto Meter 5k WOT read around 1800 when set to 4cyl. Now with the Dakota module I can see it rev up to it's full 3200 WOT. Idle now shows 750 in park.
I have 3200 rpm spring installed. I have also used the online gear ratio calculators to figure my rpm's at different speeds and they all line up. Works just fine for me. |
