Higher rate data logging Adapt flash pcm type knock system Spark cut Some ECUs have more spare inputs, some inputs may need a wiring mod. There's plenty to do lol The higher rate data logging I've finished and tested on VS just need to adapt to all bins now. The rest are still being worked on. Char...

All the ICs are either custom or rebranded with delco PNs so you won't have much luck with a datasheet.
12P will work on any 808, but the Nissan software should also be fine. 12P just has a bit more documentation and people who know how it works

i have started to look at it. No easy way but i think going down the track of limiting dwell time might be the answer? Yeah if dwell time can be limited that would work fine for most setups. Even if just the dwell time can be defined with a 50rpm revolution between 5800 - 6400 for eg Dwell limiting...

Hi Brendon, This post doesn't really belong here. Unfortunately we don't (officially) have a team of professional tuners staring at the wanted forum looking for jobs. You will be more likely to get some interest if you provide some more information in your other post. I would suggest, as a minimum :...

Completed the patch harness for the 4 wire O2, it intercepts one of the injectors to provide power and converts the standard 2 wire plug to the 4 wire one, all without any mods to the stock wiring, plug and play. Have you checked the additional volt drop at the intercepted injector connector (with ...

These were also fitted to Holden commodores of the same era.
We have a suite of custom software ("OSE 12P") and various tools and hardware available here (pcmhacking.net) to tune these ECMs and/or adapt then for other vehicles. That hardware is probably the main reason these forums exist.

Fuel pressure leak down after prime event could also be:
Pump check valve
Leaky regulator
Any leak in between

I'll assume you have checked those things.

Anyway, To reverse flush, take injectors out and install upside down in the rail. This is discussed in The1's injector testing thread.

Yes via the flex outputs, you need to use the flash tool to set it up.

Are you doing the 3x/18x v6 trigger?
if so it needs to look like the image attached.

For those of you who can't get simulated narrowband O2 signal from a wideband lambda controller to work with these (and later) ECMs: If you look at the inputs schematic and take note of the O2 sensor amplifier, you will note that it has two inputs pins. O2HI - obvious, the narrowband signal comes in...
