Robin;

Thanks for the follow-up...I'm happy the engine is finally purring (at Idle anyway) although I 'm quite leery of Injectors needing 18PSI to do it...there's something to be said for that mechanic's experience and immediately seeing there was toooo much fuel being delivered!...I cant speak to the flowrate of the VP injectors and what the different FPReg setting wants to be (or if these should even be left in the car), but this needs further studied and understood as the whole D-Jet Sys is based on a supply rail pressure of 2.1ATU (NOTHING ELSE!), and if these Injectors need half that, I don't think the ECU will be operating within a normal range throughout the entire RPM/Load/Operating Range (ECU doesn't monitor fuel pressure, it assumes it to be correct, and some of the calculations it makes I'm sure are non-linear, so these calculations would go out the window with a low fuel pressure!)...if these Injectors are flowing too much, my advice is, to install the correct Injectors, else you are engineering a new totally D-Jet configuration, and you don't want to do that, and really can't without an engine dyne plus exhaust gas sensing and analyzing...!

I'm sorry for your health issues...I suppose everyone needs to know their point of when to "cut bait", but it seems like if you've got the car running now and just need a Brake Bleed you are in the home stretch...besides, I can only imagine what surprises, pain and suffering that Jensen will provide you with...

Cheers
