so gear up! fuel pressure sensor writeup been done long time ago by TAQ, tested on himself, as well as EFILive's own Tordne, and I think BeerC5 done it too. Voltage at the pump can be easily measured, I'm not sure how different can it be at the injectors themselves.

if you think the injector characteristcs are of minor importance, i'd really like you to experience a perfectly sane STS car that does 9.x AFR on every deceleration, while it's very tame and obidient at any other condition.
