Any Supercharged drivers try running without HFM Scaler Device?

[paul e]

Whether its a Dinan Turbotronics-9, or 10, or RMS scaler, or AA scaler, all the SC packages come with them. (Not talking about the impending twin screws....just the current crop of CF blowers).

So, Im wondering, have any of you tried driving around with yours bypassed?

When a friend went to 355 whp, he took his off, and drove for several months that way. When he did, he made more torque, because without it, he became richer down low, and this assisted his torque value. Up top, I dont think it had much impact, and his afrs were virtually unchanged up there.

So Im going to carefully give it a try. The scaler may work fine with stock boost amounts, although I still have my suspicions that it contributes to the early hp peaks all dinan cars exhibit. Perhaps, with increased boost, it contributes to my less than stellar results up top. I dont think the rms scaler could be all that different from the dinan one. Maybe Ill have as good luck as Marco did eliminating it.

Sometimes, until you actually try something, and do the measurements, you dont really know how it will turn out. Sometimes, what we thought just doesnt work out that way. What Im expecting to happen is that the mixture will be enriched because the ecu will be working with a bigger signal. But Im also expecting the current 5700 rpm peak to be hit earlier. If both of these are true, Id expect to see the ltft value shoot higher negative, and this will have the unfortunate effect of reducing the fueling being called for in the wot maps. Not good. Plus, Im expecting to hit the current 5700 rpm hfm flatline earlier. Im also expecting to see a change in the peak hfm measured amount of 25.09 lbs of air.

Thats what IM expecting. But it doesnt mean it will happen this way. Dont forget that Marco ran almost a year without any HFM when he was making 355 whp with his rms kit. Gotta take the measurements.

I have not heard of anyone doing so. Maybe next time I am bored and on the dyno I will see what happens
