Re: misfire detection kit

Cheers Deggles, I'm just trying to resolve a running rich issue and saw someone with similar experience but with an Elise found the cause was the MDK. From what I've read the MDK was installed on the Exige as part of a recall to manage a potential rev limit issue cutting in at 5500rpm which was happ...

Question for the scholars on here, does the S1 Exige has this misfire detection kit as installed on the VVC?

Re: sorting VHPD drivability issues

Check the T-connectors as well when you're replacing the hose. I found a couple of mine had gone very brittle so replaced those as well whilst it was all apart. Indeed that is what prompted full replacement as i was checking the t-piece connectors one of them snapped so a full set ordered plus extr...

Re: sorting VHPD drivability issues

Hey Klaus, I'm replacing all the vacuum hoses and t-pieces, I wonder do you recall the bore size of the hoses?! I'm nowhere near the Lotus and would like to order them if someone has the knowledge of the correct bore size that would be great so I can get them ordered in time for getting them install...

Re: sorting VHPD drivability issues

Hi Klaus

Short term fuel trim I don't have a full handle on yet but does seem to be fluctuating around quite a lot, I've seen figures ranging from -10% to -17% at idle. I don't really understand these numbers and not sure what should be expected here.

Re: sorting VHPD driveability issues

The injectors have been cleaned and checked by the German distributor of ASNU machines with before and after comparison. They weren't too bad before but now they are near perfect. He told me that there is zero deviation in the injection quantity between all four of them. This could be only achieved...

Re: Vacuum readings

In my VHPD engined Exige the vacuum reads about 60kPa when idling. Compared to a standard Rover K enige this is quite high and may be caused by the high-overlap camshafts. Thanks trackrod, I managed to hook with the wifi reader and the Car Throttle Ap yesterday and got some readings, similar to you...
