Ok, as normal it seems like trying to take a sort cut an do somthing a simpler way is going to totaly backfire and cause issues for me.... but essentially I am trying to get way from the 36-1 trigger wheel on the damper, and move it to a standard MPI trigger setup to run with a K head with sequential inj & COP... so I was thinking swap the flywheel housing for the one with the sensor hole, and stick on a steel miniapares MPI flywheel http://www.minispares.com/product/Classic/C-AEG424.aspx and run the Rover #3 triger pattern BUT, i want to run my AP RTS, which it seems retards the crank signal by approx 30 degree's, and it seems that the MS code can only cope with triming up to 20 degrees from the standard position. (not sure if that +/- 20 deg, or 20 deg total either.) i know the SPI is a slightly different pattern, but not sure how, if its advanced /retared or what. any bright ideas/ insight from the MS gurus? I'm out of the country at the moment so don't have access to my detailed notes but, from memory, the SPI and MPI patterns have their primary missing teeth in the same place, it's just the sub-pattern that is different. So, if my memory is correct, although the MS code can read either, the offset between Valeo and AP will be he same on an SPI as an MPI. The figure of maximum 20 degree offset in MS again sounds familiar, but I'm not at home to confirm. The problem with those MiniSpares steel flywheels is the pattern is machined in permanently where as most (maybe all) of the standard SPI/MPI flywheels have a pressed steel ring with the patterned ring pressed into a groove, so could be moved (in theory) to suit either clutch. I haven't seen one close up but I believe that is the case. So, just a random thought, is there a suitable plain steel flywheel that you could get a competent machine shop to machine the "groove" in the back and then press in the factory MPI trigger pattern steel ring in the appropriate position ? EDIT - bit added EDIT 2 - actually, thinking about it a bit more from memory - and I can't be certain until I'm back home in the UK - I'm not even sure if the SPI pattern supports sequential anyway, I have a nasty feeling (from memory only) that it's symmetrical twice on the flywheel, with no single unique reference point on the circumference, so batch or semi-sequential only. But, can't be sure until I'm home. If Jean sees this I'm sure he will answer instantly. Edited by Rod S on 18th Jun, 2017. Schrödinger's cat - so which one am I ??? |

Use the backing plate from one of the newer Minispares AP clutches...... They have re positioned the mounting holes for the centre boss so that the AP clutch can now be used in the 'injection' engines. Bonus is that they usually have 4 drive straps per corner also!

Modified turbo casing to accept the standard crank sensor. The back was fly cut to allow a spacer to sit nice and flat as the the non injection cases are about 5mm thinner in that area (after fly cutting).

cool, so you used the turbo case for the better bearing?

Slightly off topic. I removed a pattern ring from an MPi flywheel and welded on the missing teeth to make a 36-1 pattern than pressed it back in where it needed to be. Unfortunitly the rover sensor doesn't work with Megajolt , anybody know of a sensor that will fit and work? |

Are you sure the sensor polarity is correct On 26th Oct, 2004 TurboDave16v said:

It was a while ago and I can't remember if I checked but I would think I did. I seam to remeber reading after that the sensor doesn't work with MJ although it does with MS. |
