What happened is that on a journey where it was driving as normal, suddenly over 3000 rpm it didn't want to boost, and in fact if you put your foot down it slowed down. So I had to keep it below this sort of range. When this happened the first time, I pulled over and had a look under the bonnet, because I thought perhaps something had come loose/off etc. On that day I couldn't see anything wrong, so I carried on and the car was fine.
Today, given that the problem had disappeared after stopping and starting, I again pulled over, turned the engine off and immediately back on again. The problem disappeared straight away and it was back to normal.
So it seems like some sort of electrical/electronic issue. This time I checked the AFR gauge when the problem was happening (I didn't last time), and when I was trying to make it go over 3000rpm it would go very very lean (say, 20 AFR) until I backed off again. No fault codes via OBD-II (just my usual one about the O2 sensor/cat).
Seems like it just didn't want to deliver any fuel ?
I was planning to get my map looked at to smooth out a bit of lumpiness, at the same time I will enquire about the logging in the e-Manage Ultimate. I know that you can turn on logging and it can provide various information about what's been happening, don't know if that might help pinpoint the problem ?
As I said, this is only the second time it's happened now, and I've done about 1400 miles in the car. But obviously I don't want it to keep happening every now and again.

26-03-2017, 06:33 AM #1,054Had a weird glitch today. This happened once before, on the day I picked the car up, but I put it down to a teething problem and it hadn't happened again despite having down quite a few miles (until now, that is).

sounds like an electrical issue your right, maybe the emanage or maybe a joint on the wiring?

26-03-2017, 07:03 AM #1,055the logging in the emanage is quite easy to turn on mate, just plug the usb into it and download the program from the greddy website.

I did wonder about a joint on the wiring too. This time, the problem happened after I had been booting the car a lot more than normal, after a couple of drives. Maybe it was hotter under the bonnet than usual ? (the e-Manage itself is inside the car, by a front bulkhead, though on the passenger side so not by the exhaust/turbo). Though my oil temp wasn't that high.
Very very glad I've got the AFR gauge though ! I'd be more worried without it, e.g. at least I could see it only went lean when the problem was happening when I tried going over 3000 rpm, and I backed off straight away then the fuelling went normal - so I know the engine should still be fine (i.e. I didn't end up with it running hard with lean AFR).

26-03-2017, 07:21 AM #1,057Thanks guys. On the logging, I had a look at the manual and it looks like it can store quite a lot of data (up to 1000 minutes ?). So I thought one option is turn the logging on, then if/when it happens again I can get the data looked at (presuming it's in some sort of wrap-around storage where the new stuff overwrites the oldest).

Again, it happened while going along the motorway. I pulled over on the hard shoulder, and stopped. I was going to turn the ignition off, but before I did that I thought I'd have a quick experiment on the hard shoulder to see if at very low revs it would happen. The car was only standing about 20 secs or show, just while I leaned over and checked the e-Manage to see if it felt hot, but it didn't at all (didn't really expect it to). However, to my suprise, when I tried going along the hard shoulder, even when I put my foot down, it worked fine. I pulled back onto the motorway and it was fine all the way home.
So it seems it wasn't turning the ignition off and on again that reset things. Just pulling to a stop seemed to do it. So now that makes me think again about the problem. Perhaps next time I will try just going very slowly and speeding up again, or to see what it is that I seemingly need to do to "fix" the problem.

27-03-2017, 08:41 AM #1,058Had another motorway trip today, of a couple of hours each way, and it happened again on the way home. However, I found out something new about the problem.

sounds like a electrical glitch to me as well was there a small bump in the road or anything like that bit of debris cats eye changing lane roadworks you know usual stuff on roads as it might be a vibration that is loosening a joint but upon stopping the wire moves back to contact point .....

the problem is the std map sensor seeing boost when it shouldnt,the fix is eather in the mapping or get another map sensor with an output voltage close to the original.we got over this in the mapping.
