The H Series and B Series setups should be very similar. I did an H22A build a few years back and it was pretty much all the same stuff just more displacement. All aftermarket standalones are going to like the crank mounted signal more than the distributor signals so for that reason alone going with...

Just an update. I'm starting to have issues with the 4.9 on the EMU Black setup after about 3000 miles. I haven't had a chance to fully diagnose the problem but the other day I shut off the closed loop control because I was having unpredictable part throttle performance. When I did a few logs I noti...

The car has been running great for about 2 months now. This car is my winter beater daily driver and I commute about 50 miles a day in NYC traffic. It has some trouble with starting on cold mornings less than 13*F or so. It will start but it requires a lot of cranking. The oem Honda ECU probably has...

There is a long road ahead converting from the stock engine management over to any standalone. I'm sure the EMU Black is capable of running your setup to some extent but there are all kinds of crazy things OEM's do with modern engine management. That may mean your current ecu is doing more than engi...

I've had both setup on different projects and the 4.9 has been more reliable for me. This was using an AEM controller for both the 4.2 and 4.9. I started switching all of my projects over to the 4.9. I'm only using the 4.9 now on the EMU Black and I have about 1500 street miles on the setup so it ha...

Thanks for taking the time to check that out! It seems obvious now and I should have suspected that. The Honda distributors are notorious for wobbling at high speeds. I'm sure noise could be the problem as well. ECUmaster tech support also replied with some recommendations on how to solve the issues...

The dash is probably the biggest problem because it uses Toyota's BEAN network. There is someone out there working on this now and Apexi cracked years ago. Apexi is one of the only pnp standalone for the MR2 and Celica among others. Hydra must have figured it out too because they also have one but i...

Got back to driving the car today and there is still a bad misfire at 6000rpm. It seems to come and go which is really hard to diagnose.

I've attached the log if anyone has any ideas. Here is a screenshot of the spot.

I have the car running pretty well. The EMU Black is a truly nice piece of hardware. Very intuitive and easy to dial in. I hope the mods here can get the forums under control. With a little more community support I could see a lot more tuners turning toward this as an alternative to the other compet...

Ok, It sounds like it syncing. Do you get a steady RPM recording in the log while cranking? Do you have some sort of timing light you can check your base timing with? Did you read through that other thread I posted? It might help get you on the right track with setting up the timing. I'm not very fa...

Are you getting a good consistent sync state while cranking? That's the first thing to check. If not, something could be wired wrong or setup wrong in the ECU for the different sensors. I'm not that familiar with the M52 and where the triggers are being pulled from. If it is fully syncing, you will ...

There doesn't seem to be any real info about the setup for a Honda B series so I will post my current setup. If there was some documentation on this it would have saved me tons of time. I still don't have all the details worked out yet but I have the triggers and ignition working correctly. The car ...

Scott, I have a base tune setup from the Lotus 2zz - GE application and it sends a PWM to the VVT-i from any one of the AUX outputs. (specifically AUX 6) This is on the low side of the VVT-i solenoid. The high side gets a steady 12v if i'm not mistaken. I'm not 100% sure on this because I have a lot...

Parametric Outputs can be useful for many things so I think expanding on this a little would be helpful for complex setups. Can a "Variable operator" option be added for between two values? Something like VSS between 50 and 100 or RPM between 500 and 5000 could be useful. Also adding a few more logi...

So it looks like running the alternator control probably isn't an option for the EMU unless they build something into the software. Here is a post on the AEM board about the same issue. Something I was slowly discovering as I researched more.

This might help clear some things up as far as functionality required for the 1zz-fe ECU in the MR2. I grabbed this spreadsheet and made a copy so I could alter it for the EMU Black setup. Haven't finished yet but I think the EMU Black actually has a little less functionality than the the AEM EMS4 s...

Anyone have any recommendations on running the Honda ELD and Alternator Control with the EMU? It's a pretty basic system that sends a 0-5v signal from the Electronic Load Detector to the OEM ECU. That's essentially a current meter for the entire car with a sensor signal output. The ECU then sends a ...
