[RICE RACING]

In this application the nozzles have the check valves.
I can put up a graph to show when the WM50 kicks in and the effect on Lambda, as per Richards advice we use his control box, but have the WI status into the ECU, the flow meter output and the strategies are working around that, his box drives the delivery valves.

We run allot of fluid, and even I was surprised at how good it is, the Syvecs S8 has a customer fuel modifier based on the flow meter input, and it manipulates the fuelFinal injection amount accordingly. This car is spastic fast in the first 4 gears and even with all 4 wheels spinning obviously the traction control is taking over and thus you cant use or rely on closed loop fueling so the interactions between both systems is very linear.

Its a car that runs in a hot ambient environment, its not uncommon for us to see AIT (measure inlet to turbo) of over 55 deg C after sitting in traffic and its fueling is always spot on.

Regardless you have to get the fuelMltCll1 to within a tight tolerance and this is especially hard on a port throttle engine like this set up (kept for ultimate response) and I use a complex strategy that takes into account varying and constantly moving map/tip ratio with my own derived air flow correction to suit this specific engine (its never a text book relationship) rather it varies based on the cam specs mostly, regardless its not easy or quick to set up but once done right it works fantastic. This is why I don't rate ANY of the Ve models with a baked in BS set up done by a computer programmer as they don't really understand any of this as they don't make engines themselves nor work on a large variety of them. I find it much better to develop all this yourself and work in true motorsport ECU way in ms defined maps (Life Racing, Syvecs, Cosworth, Bosch, Marrelli etc) and forget all of the crap fudge factors and excuses that get mentioned on the internet LOL.

Off topic but thought I would explain some of the items that can confuse some when running WM50 and then trying to explain why they have a difference in fueling in differing conditions, most cases especially when turbo charged let alone port throttle application there is allot that changes the demands of the engine.
