Dakota Digital Speed Convertor Box for K Swaps CSS to VSS.

[@ohxietviet]

Not sure why so many people seem to be having this issue. I just wired mine up and don’t have this at all. I used OUT5 like someone recommended here and set calibration to 1.42. It’s pretty much spot on with 0 lag. This is with a k20z3 trans in an EK. I’m no k-tuned hater but it would be ridiculous to think they made a better converter than a company that specializes in this.

I've work with the tech "they say" is expert at Dakota Digital many hours on 2 different identical unit to rule out a defected unit. Even tried all the ports, even the one you've mentioned. Even had a voltmeter hooked up while testing the unit while driving with no solutions on why it didn't work. The tech's there finally gave up on me and I still had to pay for a unit that didn't work for me, so I opted out for Ktuned and it worked right away. I would of kept using using Dakota Digital if they could of figured it out, so all I was doing is just posting my experience here.

@@jsrebuilds3951 oh nah I believe you. Just not sure why this is happening to so many people. Seems like a defective unit.

[@jsrebuilds3951]

@@ohxietviet I would of like to use the Dakota product because it does have more features but they didn't even give me a refund any of those defective units. I called Hybrid Racing and they use to have one but they discontinued because something with theirs wasn't defective. If I could of opt out of not using K-tuned, I would of.

Mine is wired exactly like yours on my rsx. And im having the EXACT issue. It takes a while to start reading speed

[@jsrebuilds3951]

The only thing that I know about the RSX is it uses a multiplex signal that comes from the ecu. The Integra's and Civic's at least the older ones that I know of uses a signal directly from the speed sensors.

@@jsrebuilds3951 thanks , i already fixed mine. I just wired it up with kpro . I got rid of the dakota box

[@jsrebuilds3951]

@@garciac619cg yeah you don't need any of these boxes. Kpro or any rsx ecu will work directly.

K-Tuned VSS converter box instructions says to tap the box GND wire into a GND wire from the harness, not connecting it from the box to a chassis ground.

[@jsrebuilds3951]

Ok Sean, I will give that a try and hope that would solve my issue. Thank you for reaching out.

@@jsrebuilds3951 I should have waited to post until I tried this myself, which I did tonight. JDM CL7 swap into an EK hatch, 02-04 RSX engine harness. DD SGI-100BT. I connected the DD GND to chassis ground, engine harness ground wire from KTuned instructions to SPD- on DD. Settings: H-L, LO input voltage advanced seeing, input pull-up ON. Initially went with OUT4, but the speedo was reading about double, so switched to OUT5 and it is really close. Very little adjustment needed. Unfortunately I am also getting the lag after longer stops but it seems to kick in around 20 not 40. Brief stops are fine. Application #3 in the instructions says to wrap VSS signal and ground wires together to minimize interference (which I didn't do) but I am doubtful it will make much of a difference.

@@seancostello387 Thank you for responding to the comments and helping us out. I've worked with 2 of their techs extensively and I know their tried to help me out but they are not willing to admit that their product doesn't works for our application. No one has responded if the ktuned box is the better solution.

​@@jsrebuilds3951 I see the Hondata sticker on your ECU. If you are running KPro, depending on your version, you could do the conversion at the ECU and not have to worry about an external unit. If you are trying to avoid spending even more money on the KTuned converter. kzbin.info/www/bejne/d2WQdnalbrGomtU

[@jsrebuilds3951]

@@seancostello387 Hey Sean, thank you for this comment.Yes I do have a Hondata kpro v4. I've tried what vtec academy recommended on this video you sent me and it doesn't work either. I've actually called Hasport and talked them to make sure I was doing it right and it turns out it doesn't work at all. So I reached out to Hondata and they confirm it doesn't work the way vtec academy says. Hondata says their ecu is not made to be able to switch it to reading the high frequency of those kinds of transmission.

Hi mine is in a jzx100 as soon as it gets to 60 it drop to zero any ideas why this is

[@jsrebuilds3951]

Are you using the Dakota Digital and what swap and chassis are you running?

[@relaxnheal8640]

@@jsrebuilds3951 yeah running that box I don't have a swap I put a sequential gear box and the Speedo used to run of the old one so tapped into the abs sensor

I have the same box with a j swap and I can not get the bluetooth to show up on my phone. I went the the screen for blu and checked in my settings and in the app and it never shows up. Anything I can do after getting to the blu menu before it goes into bt pairing mode?

[@jsrebuilds3951]

I don't know the answer to your question. You should reach out to Dakota Digital for tech support. I'm leaning towards getting the ktuned vss converter.

[@PaChiLa_Leader]

That sux man

[@jsrebuilds3951]

Yeah I agree

[@sugilim6255]

I have the same issue on my Dakota sgi-5e Mine actually not as laggy as yours bit still lags. Another issue I have on mine is the speedo would actually drops the speed reading to zero under heavy acceleration or vtec. I'm convinced dakota just sells rubbish product for our kswap cars I'm gonna try using ktuned speed converter next Everyone seems to have good result with that

[@jsrebuilds3951]

@Sugi please let us all know how that goes, this is very frustrating. Thank you for your feedback.

[@colecampagna6302]

I am having the same issues with the dakota. Did you ever resolve it?

[@skyline34x]

U should’ve gotten the ktuned vss converter

[@jsrebuilds3951]

Do you know if the ktuned vss converter works correctly?
