Hay guys, i must admit that you all have good point. I don't like a pfc mainly because of the price youpay for the name, and so forth, yes it's plug and play, but has limited features.
I have done a fair bit of work with a MegaSquirt system form the US on our targa car, and it's GREAT.
Seal map tunning, cold starts exct, but not plug an dplay as such, would need to make up a harnes and some of the sensors would need to be changed. But overall it's great.
In regards to my issues, idle warm at 650 rpm is 18 in Hg an dno more, i have read a whole heap of pages and so forth, doing all their test, it shows that everything is ok, ie no stickying valves ect.
I am doing the full pressure test again tomorrow and see what i find.
One thing i did was put the hand over teh intake and the car stalled straight away, and while under 30 in Hg of negative vac, there was no leaks that i could hear.
I need to reste the timming and the idle to ensure all to spec and go from there.
Thanks for all the advice, i'll keep you all posted.
