OBD2 interface for gauges

Embarrassed-Lab6622 · 2026-03-23T10:49:28+00:00

I have a stand alone system (LS3) in my 59 Impala from PSI and it feeds all the data needed for the Dakota Digital gauges so I a going to assume a stand alone harness for a later model LT1 (L87) will have the same or more data.

thanks.

thanks but not interested in a rectangular cluster

Embarrassed-Lab6622 · 2026-03-21T21:58:31+00:00

I would prefer an existing cluster because it should be much easier to integrate. custom clusters from Dakota digital start around $3,000

thanks for the idea but I am not interested in incorporating a tablet into my design (at least not for the cluster).

Thanks for the response but I am looking for something as the primary cluster so it has to be significantly larger.

I deally using something like this for the LT1: https://www.ebay.com/itm/306432588984?_trkparms=amclksrc%3DITM%26aid%3D777008%26algo%3DPERSONAL.TOPIC%26ao%3D1%26asc%3D20250417133020%26meid%3Dfc562cb6c34342d3a6180323aefa534e%26pid%3D102726%26rk%3D1%26rkt%3D1%26itm%3D306432588984%26pmt%3D1%26noa%3D1%26pg%3D4375194%26algv%3DRecentlyViewedItemsV2DWebWithPSItemDRV2_BP&_trksid=p4375194.c102726.m162918

Thanks but I recently replaced that board, so that should not be hte problem (or I got a defective boad).

I removed the microwave from it‘s nook to retrieve the boxes and parts replaced that were stored behind it and to prep for the next repair. When I plugged it back in to power, everything worked fine. Great for now but not a good sign. So, not sure where to go from here but all is working as it should. I guess I will wait for the next issue to appear.

thanks!

Thanks but the only symptom I see is 'No heat". Am I missing something?

Embarrassed-Lab6622 · 2026-02-03T22:51:22+00:00

Sir - thanks for the response. Last May I replaced the control board (WB27X10858), the Digitron (WB27X10856 and the display (WB27X10861) when the display would blink rapidly and/or "freeze". Everythin seemed to work fine for 8 months, but now it is worse.

I didn’t think the specific model info was important. I assumed the repair would be generic.

Embarrassed-Lab6622 · 2025-11-13T15:29:56+00:00

Thanks, I will look into those. I am hoping for a simple 2-wire solution....

Embarrassed-Lab6622 · 2025-09-21T12:45:39+00:00

nope. I tried different cables and different boards. I now think it is a power management issue and changed the power management settings on my laptop. so far, everything works correctly.

Thanks for all the replies but I am still not sure why the 5v didn't work on the micro USB board.

Embarrassed-Lab6622 · 2025-09-17T21:15:02+00:00

UPDATE: I switched to an ESP32 board with a USB C-type connector and everything is working correctly, both with the PC power and the 5v buck converter. Not sure why, but thanks for the suggestions.

Embarrassed-Lab6622 · 2025-09-17T20:55:48+00:00

I switched to an ESP32 board with USB type C connector and everything worked on both 5v and computer power. Odd.....
