    He tee's right at the manifold, so the boost curve is what the engine is seeing.

    Cheers Jim

    don't suppose you've got my lpg boost plot in with all your bits of paper??

    You got what I got given, the only extra printout I had was one that GWS asked for and I got Steve to print a copy off. Did you only get power/torque graphs then?

    I got power /torque and power boost for petrol and power torque and power/AFR for lpg.

    Steve C logged first Vpower and 1 st lpg. but highest V pwer was 2nd V power run am keen to know whether the boost instability was recorded for lpg run? don't think it was as torque curve much smoother.

    My runs on the Fozzy showed some jigger on the pressure data from the Rolling Road whereas my datalogging showed a rock solid 1.21-1.22 bar from 3000 to 4700rpm and then a steady tailoff to 0.95 @ 6400.

    The Rolling Road has a much higher sample rate than OEM ECU datalogging which is pretty poor when lots of parameters are being collected.

    what was the amplitude and time period, (or rpm period for convenience) of your "boost jigger" mine had peak to trough amplitude 0.12 bar damping down over 3 oscilations. peak to peak period ~ 500rpm I'm surprised if the OEM ecu log didn't pick that up :?: But this is the one run Steve C didn't log. :roll:
