Help needed please !!

Carl - I have just tried resetting the ECU like you said, didnt make any difference though (does it work on a Apexi).  I can\'t drive the car on light throttle.
It deffinatly not the pipe going to the map sensor as I have replaced the pipe with silicon hose and have tried swapping the map sensor for another one I had and it didn\'t make any difference, unless both map sensors are broke, but the one that is in the car now was working before I did te engine swap.

I was wondering, could it be anything to do with the boost controller, if I had it plumbed in wrong or its not set up correctly, as that has been sat for over a year aswell, not sure if it can loose what was programmed into it?  Its a Profec 2 boost controller.

Have just checked my boost controller and it is plumped up the way it says in the instructions, so guess that rules that out.
I also started her up and let her get up to temp, then took her round the block, seems to drive ok in the low rev range is a bit lumpy, but as soon as I tried to accelerate a bit more it would just start to missfire.  I have also noticed that if I try and rev the engine quickly it sounds like it is missing.

Just read you have checked for settings are still on 1600cc injectors on the APexi, what is the base fuel pressure?

[BlitzBoy]

To check base fuel pressure the vacuum hose off the fpr at idle

[BlitzBoy]

Also double check on the commander the boost pressure readings tally up with ones on a boost gauge

[dturpin]

The commander still says 1600cc in the settings, just went and checked the base fuel pressure, when I pulled the vac hose off the guage was reading roughly 58psi on the pressure gauge on the FPR, when I connect the vac hose back up it goes down to about 40psi.

[BlitzBoy]

ohhhh Houston we may have found your problem!
give me five mins Im gonna recheck what base fuel pressure is suppossed to be at idle

[BlitzBoy]

Ok have read the Factory manual with the ignition on but the car not running, fuel pressure should read 36-38psi.
So check it now with the ignition on but the car not running let me know what you have.

[BlitzBoy]

woops almost forgot you need a jumper wire on the datalink connector (between FP and GND) when switch the ignition on, pic below

[dturpin]

will go and do that now then, give me a few minutes.

[dturpin]

right just checked that and it is about 56-58psi, forgot to mention that when I first switched it all on for the first time the FPR was making a hell of a noise, so read up on here about it and ppl said it usually clears itself, which it has done.  But was wondering if it could be not working correctly but has just stoped making the noise.
Will that factory satated fuel pressure be the same on a single turbo car?

[BlitzBoy]

wow!!!!!!!!!!!!!!! thats to high 56psi!!!!!!!
You need to turn the adjustment screw so you decrease the fuel pressure on the same test I gave you to 38psi.
Once you do that drive on light throttle no boost and see if you can go past 3k this time, I wouldnt go into boost as I reckon you will need a remap.
Let me know if that works

[dturpin]

Have just checked it and and its about 56-58 psi.

[dturpin]

Do you think that the FPR could be broke then as it hasnt been touched since it came off the other car and was working fine on there.

[BlitzBoy]

Well you should be able to lower the base pressure with the adjustment screw back to 38psi, see if you can adjust it lower, if not then its fubared.
Were you running the same pump between both cars by the way?
