Big problems with MattJ's install.
Matt reported erratic spark on cranking, and then no spark. We brought the unit back to my test bench and it worked fine.

The unit was sent back to Matt and he tested it - exactly the same problem: No spark, and the fuel pump primes okay, but after cranking the pump stays on all the time.
Matt then removed and refitted all of the fuses, and started the car! The fault is all mine as the fuse holders were not labelled, something I will be addressing in all future installations.
The fuel pump still stays on after the ignition is turned off, I think this is similar to a problem I had when using a FET to drive the fuel pump, so we'll use the p259 ch5 as per usual.
We still have the transient supression diode to fit, the boost controller to configure, the fuel pump to sort, and the knock sensor to fit and tune.
But it shows that the Toyota loom is working but that the fuses need to be properly labelled and some more work on the fitting guide done.

As requested on AFreshTiny page.
AFreshTiny 5A control.
It would be good if the 5A control could be activated in a similar way to the Genboard Misc outputs.
Trigger on/off on:
- Lambda - so that the system can turn on a 5th injector or warning light.
- EGT - to trigger water injection, 5th injector, turn off boost solanoid or trigger a warning light)
- Analog Input - to set on off points with either boost or tps - would work well as a 'soft' TPS switch to turn on n2o systems or any of the above suggestions.
