That's interesting but if (and I'm only throwing ideas around) Darryl's car thinks he is still cranking it could be massively overfuelling as a result.
Aha some numbers - I'm assuming that's with (bigger) non 440 injectors as well Ian yes? If so then those figures are definitely in the ballpark Darryl is seeing. Progress?
Good - makes for an easy test of rpm then although I'm sure Darryl would have spotted this if it was very low so maybe that's cranking pulsewidths ruled out altogether?
Does anyone else know in terms of water temp when the stock ecu is out of warm up?
How about comparing Darryl's coolant sensor output compared to a good working car both at the sensor and at the ecu - hopefully checking both the sensor output and the wiring?
Darryl - what is the idle like the instant it starts, is it ok for maybe 20secs or is it rough straight away? (This needs to be with good non fouled plugs)
