I think it could work, but would be a project. There are enough unused inputs on some obd1 computers to gather the few missing sensors. The rest would require some put of the box thinking and some access to the datalogging port or dlc connector.

Or use a RSX ECU and have the option to run COP.

This may be a worthwhile project, the downside is k-pro is the only current option available.

I forgot about that portion. In addition, no EMS has flash memory to do what you want, so that you can still use the OBD2 diagnostic port. (Shown on the page 1)...

Sorry about that.. good luck.

Pretty much have given up on an OBD2 system. Only option I see that could work would be the Greddy eManage Ultimate. Can't find much info on the web of peoples real world experience and what level of control I would have. For the money I would spend on the eManage I think my best bet is the Neptune RTP and I am trying to get the cash together for it and the accessories I want.


Thanks for the picture you sent me earlier.

PRB.......

Salami

Looks like I missed a few posts on this page. Would be a huge PITA trying to get one to run right on a B-series, correct? If it could even be done at all?



Huh? What is PRB?

Natural Aspirations

PRB is the 02-04 RSX ecu that works with K-Pro, It would take some work but the benefits are an active OBD-2 port, integrated WB02, COP.

By no means would this be a direct plug and play affair but its a step forward and no more than S300 and CPR and a wideband controller.

Oh.. yeah.. I use that also on my brother's turbo car. Works quite well, too. there are a lot of sensors that can be bypassed or turned off if needed. the values for tuning go from 0 (based upon the values defaulted from the ECU), and is pretty expandable.

What injectors? 240cc?

Sorry to bump an old thread, but I was researching some OBD2 EMS options. For other cars there seem to be some form of parallel ECU (for example Haltech for 350Z). Meaning the factory ECU thinks it's controlling the engine, but it's controlling nothing, the aftermarket ECU is controlling the engine. Are there anything like this for Honda? I live in a place where they do the OBD2 plug emission testing, so as long as the ECU is tricked into thinking everything is fine it'll pass.

What you are suggesting is extremely illegal and would result in trouble for anyone who even discussed doing it with you, ask the guys at EDGE tuning.
Plus, it is way more work than you need to do. there is a guy who is running a k-series harness on a B, which can also run a K-series ECU. Meaning you can run Kpro, have coil-on-plug ignition, built-in wide band 02, full OBD diagnostics with an operational OEM plug. As long as you could pass visual inspection this setup would even pass in California, which in my opinion would be about as close to the perfect solution as we could ever ask for. Tuneable ECU, OBD2 compliance (in the spirit of the law, not exactly the letter of the law), INVISIBLE because it is basically OEM, you could even run an immobilizer if you wanted fairly easily.

Here is the thread. Everything in the guys project is completely doable, some enterprising tuner and wiring guy could combine forces to sell a package that would truly change the game for anyone running a 96-00, it would be comparable to the difference between hondata and a V-afc.

To be fair, that is still just as illegal. All of that still counts as tampering with an emissions control device. It's not quite as bad as sending false passes to a scanner, but the law wouldn't care if you made that case in front of a judge.

i still want to do something similar though, just for the sake of having a more modern ecu with better capabilities to run the car... COP, modern knock control, etc... Even the potential for DBW throttle. OBD1 ecus leave limited options on the table.

A lot of things we do on our cars are illegal. If anyone sells a kit they will definitely label it "for offroad use only". Where I live there don't have visual, so as long as OBD2 gives the correct response I'm good. I think due to my limited technical abilities, E-Manage Ultimate piggyback might the the only option for me.

I said "spirit of the law" lol.
For example: Running an OBD2A p72 ECU via jumper in an OBD2B Integra GSR would pass every conceivable emissions test, but would be Illegal under the letter of the law.

My dream would be running K-pro which allows for up to 5 different Maps if you don't use VTC which B's don't have anyway.
1. Daily Emissions sensible tune - best MPG, cleanest and passes emissions with flying colors.
2. Aggressive street - "Type R" type tune, might even pass emissions.
3. Street e85 flex fuel
4. Track Full e85.
All switchable via my phone's bluetooth.

There are people discussing running Megasquirt parallel to the stock ECU, but I haven't been able to find anyone trying this on a Honda.

https://www.diyautotune.com/support/...uirt-parallel/

I'm going to attempt a full Mega Squirt setup in parallel with the stock ECU - LS1TECH

Contact me if you need help tuning the Megasquirt. I have tuned several of them. My B18C Type R will be coming up soon on one.
