I'm hoping very soon, 99% of the hardware is the same as my last 2 versions, so its really having the pinout correct on the plug and i believe it is correct.
Maybe over easter i can get one tested, i have found a single cam engine I can try one on for now. If everything is ok with that it should be ok.

Number 1 ready for testing. I haven't put all components on is one as i just need to see it run a engine and that everything operates.

Sweet , if u need test pigs i have more than enough , single and dual cam D H B series hondas for testing . The design looks super as it stands now.

no updates sorry, i haven't had the time to fully test, I did get a prelude started and run for 30 seconds on it, but didn't get into tuning it as it was just to diagnose a faulty apexi ECU that was fitted to the car i was testing. Ive been on the look out for a test vehicle for complete testing, but im out of room with currently 10 cars sitting in my yard and on the street.

Completely understand that. I am torn between doing speeduino pcb with obd1 honda pinout like you've done here being as I could use readily available firmware. I would only require developing the hardware.
My other option is to use socketed obd1 honda ecu with an emulator. I won't spend the money for a moates ostrich. I have done the schema and PCB artwork for a 27c256 or 27sf512 emulator. It used atmega64 or atmega128 and 2 banks of 128x8sram. I however have zero capability to write firmware for the device. Would be nice to do and use existing hardware protocols that are openly available from moates so that the device works with existing softwares. Crome,ectune, tunerpro.
Would love to complete the project and make it open source to the public.
Sorry for rambling. Not trying to hijack your thread

I think if you make a plug in to the standard ECU board it would be the better choice as your using known reliable hardware.

Willing to be a test pig if you intrested. This days I'm installing a 0.4.3c board on my honda!

Finally got hold of a test engine. I will start doing full testing on these and hopefully start marketing as soon as im happy.

Had it running for a short period again. Same as […]

Ok, here is the first version of the adapter plate[…]

Ignition Angle doubled?

don't load your old tune in case it is corrupted[…]

Yes, totally wrong setting. Slight noise in TPS ca[…]

Still can't find what you're looking for?
