Built-in programming buttons and LED display for setup in lieu of app. Not for use with ABS sensors or systems.

Review: Working out great on my S14 240sx/2JZ-GE/W58. - I initially wasn't going to buy this cause of the price (too expensive for what it is.) but after other failed converters on the market (not much of them) I broke down and bought this. I bought this for my 2JZ swapped 240sx. It works great for using the speedometer and tachometer. What's extra nice is configuring this via bluetooth using my android phone, works great. But they do offer configuration by the unit too if you don't have a bluetooth phone. I especially like the frequency tester to know if you got everything wired up right. Overall I'm impressed by the quality, just not by the price. I would recommend this to others, but there isn't much choices out there, so it's your only choice sadly. As a random note to others if they are doing a 2JZ-GE 240sx (S14) swap too. My wiring is as follows: Ignition+ to an Ignition 12V source. Ground- to a ground spot on the car. Speed/Input to the output on your 3-wire speed sensor on the transmission. Speed/OUT1 to the R/Y from the back of the gauges (either wire it directly to the gauge or to the plug under the engine bay fuse box, and leave the R wire not attached to anything.) Tach/Input to the 2JZ-GE's Igniter's TAC (pin 4) output. Tach/Norm to the L/B wire (TACHO) that is on the F3 connector that normally would be coming from the factory computer. Now for the software side (via the bluetooth software.) Speed Setup: Input Type: Low Pull-Up: On Input/Output: Low/Low Calibration Value: 2.0 Speed Unit: MPH Tach Setup: Fuel Type: Gas Input Cyl Count: 6 Input Type: High Calibration Value: 1.0 Output Cyl Count: 4 Output Voltage: 6-18V
Review: Amazed at how well this worked for my Ford 5.0 V8 swapped Miata - My 5.0 Miata has always had a tach that would jump around and despite tuning an adjustment in the cluster, was never really accurate outside a ~1000rpm range. Purchased this interface hoping it would at least tame the wild tach needle a bit, but was pleasantly surprised that it got my RPMs displaying perfectly on the factory tach. In my case the fiddling I did before made it less simple than setting Input to 8cyl and output to 4cyl, as that setting the tach reading pretty low. Once I switched input and output to both 4cyl and adjusted the fine tuning value, I was able to match the tach to what my ECU was outputting to my laptop. I really liked being able to adjust the unit through Bluetooth, as I will be hiding it behind some plastic trim. The app was quick to download, and it was easy to pair and use. I paid $100 for the interface, and I believe it is worth every penny. Definitely exceeded my expectations.

**Q: Will this make an oem tachometer work in a 1990 pontiac firebird which has had a 2001 ls1 engine and pcm swap?**
A: Nor sure , it probably would. I put a 283 with hei  in a 2001 Chevy Silverado.  The truck had a v6 in it . I set the dakota box on 8 cylinders in and 3 cylinders out and it put the tack on the money . Chevy  sends  half cylinder signal to the tach .  May have to play with it to find your setting .

**Q: Will this work off of the stock flywheel sensor or do I need to buy the one sold separately ?**
A: This Universal Speedometer and Tachometer should be able to read from the stock flywheel sensor, if you have more questions, please let us know.

**Q: Will this work on a 2007 tacoma?  not sure if my truck has abs and the info says not for use with abs sensors. i thought everything had abs now**
A: I would go to the Dakota Digital website and ask them.

### ⭐⭐⭐⭐⭐ Worked nicely, just what I needed.
*by A***X on December 24, 2024*

I have a 90 240sx that I wanted to keep the speedometer and Tachometer working on the stock oem anolog cluster. I have a 2jz that has a r154 first gen transmission. I had to buy analog to digital signal speed sensor from a company called driftmotion to get this to work that goes on the r154 transmission. The app is alright but does the job, you can calibrate the speed using the GPS speed on the app. The Tachometer I was able to take signal from the ignitor chip then fine tune it using the app, cylinder count ect. Worth it if you want to retain oem analog cluster. I've seen these work on ls1 swaps as well.
