I am pleased to announce that the Honda SS-OBD1 boards are finally at the beta testing stage and will be available to the general public very soon, but first a little introduction on what exactly this board is.
Built on the The Simple Solutions OBD1 (SS-OBD1) line of adapter boards introduced in 2019, which were made to make connecting 90’s vehicles using the popular Nippon Denso 48, 64, and 76 pin connector integration with the Speeduino V0.4 line of ECU’s, quick and easy, the Honda SS-OBD1 is the future of affordable Speeduino to OBD1 Honda integration.
The 76 pin connector plugs directly to the Honda’s factory harness by using 3 out of the 4 connector plugs. The Honda SS-OBD1 board then cuts off 95% of the wiring needed with the traditional SS-OBD1. The user is only required connect the ribbon cable from the Speeduino to the SS-OBD1, connect power and ground supply wires to the Speeduino V0.4, and wire up wideband O2 input. The onboard jumpers will allow users to quickly select appropriate ignition system configurations.
Current version 1.0 of the Honda SS-OBD1 supports flex fuel, boost control, launch control and coil on plug applications.
Beta testing will commence in a few days on a B series Vtec powered Honda however final product will be suitable for use on B, D, F, and H series engines. #staytuned

Initial testing revealed a few design flaws with current PCB. Version 2 will has been made and testing will commence as soon as they arrive.

Its been a little while since I did any sort of work on the Honda SS-OBD1. Version 2.0 is finally here. The new board has passed the bench testing phase and is ready to move into beta testing. The new PCB has minor layout changes which should make assembly and use a lot easier. Also new to V2.0 is the addition of ethanol content sensor (Flex Fuel) input to the AUX I/O pad. This now means that users can easily use a flex fuel sensor to tune their engines.
I hope to identify a test car and have these PCB’s fully tested in the coming weeks.
The Honda SS-OBD1 boards are officially available to the general public, exclusively through WTMTronics https://wtmtronics.com/product/honda-ss-obd1/

How much for new speeduino standalone ecu. plug n play kit.
Price is not yet set in stone but the PNP Honda board is expected to be sub $80 for assembled board plus enclosure.
Very interested in purchasing and testing on some higher hp cars.
There has been no news since Oct 2020, anything new? This seems to be a great set up for what I need at the moment.
Hello Kevin. Funny you mention it. We are just about to send out our last test board for independent beta testing then we should have the PCB available with the next 30 days if all goes well.
When can I purchase one
Hopefully within the next 30 days
Where can I buy one
They should be available from WTMTronics.com within the next week 14 days
Can you post to UK?
Yes once available they will be shipped worldwide
Will this work for ef civics obd0 converting to a obd1 engine using a rywire or comparable jumper harness?
I have not tested this but I see no reason it should not work
Very nice
Hi i want to purchase your honda obd1 adapter to use on my SOHC F20B turbo setup.
My questions, does it come soldered ,
Do I need a custom trigger wheel,
i have already ordered from WMTronics a speeduino 0.4.4d and a adruino mega
and have in my cart your SS-OBD1 adapter and Minimax A2,
would also like to know what else would i need to make a smooth as possible installation
This is an adapter board for the v0.4 Speeduino. It retails for $45 usd from wtmtronics.com
Your 40pin ribbon header on the first picture shows its installed with the notch facing away from the obd1 pins. Your last 2 picture shows it facing towards the obd1 pins…. Which way is it supposed to face? Why do I not see any detailed pictures of how to install the pins?
The board has undergone many revisions as documented in the blog under the various dates. The version number in the lower right corner also changed with each revision. Please reference the latest blog photos and update details for correct board and component orientation. Also in absence of the blog photos, you should always use the orientation displayed on the board you purchased.
We made an overview video about this board that may offer more clarity. You can view it here https://youtu.be/IM0i70GcvVQ
I have a question I purchase the obd1ss adapter and my question is the orientation of the IDC is the same as far as plugging it up to a 4.3 and with that being said if I was to use the IDC adapter on the obd1ss Honda and cut the other side of the wires can I then wire it up and know that all the orientation from the IBC plug will be correct to match to a UA 4C white fang.. I know you’re busy man I apologize to bother you and I hope this is not a stupid question I just want to make sure the orientation on the IDC for the Honda plug and Play board is accurate so I can match it up to my UA 4C
