Earlier the torque curve just curved from a low issue steadily upwards. The adjust Later on was a massive and flat torque curve. From 3000 to 5500 revs the torque ‘curve’ was a lifeless flat line. Despite the VVT solenoid temporarily unplugged it however has far more energy about the whole rev array compared to earlier ECU.
They're also superior for rally purpouses coz when rallying, the whole point is to keep the revs as large as feasible for max. electric power, So the engine normally has VVT activated at least, Otherwise it truly is from the 'power band' from the engine.
Superb assistance all through. My new mower arrived the working day right after I’d requested it. Much appreciated.

Manifolds that maintain the throttle bodies on an upward angle are hardly new but The problem is of their angled transitions. The norm is to just Use a straight port along with the facial area that's been welded / machined at an angle relative towards the port. This process tends to make to get a very easy building but The problem with this method is the fact that when air is forced to change in angle much more than a small diploma the laminar air movement layer will independent resulting in turbulence and a resulting flow restriction on account of it.
