First Datalog with Turbo Speed Sensor

[wesk]

First datalog with the nifty EFR speed sensor installed. I am not really doing anything with the data beyond using it for reference, but it is cool if you have never really watched it.

The channel is named "MAF" and this is of a 2-3 gear partial pull. Interesting things to look at are rpm, MAP, TP, boost duty, and boost (calculated from map). Multiply "MAF" times 1000 to get turbo rpm. IE, 130 equals 130000

Interesting how closely the shape of the curve correlates so closely to MAP and PW, other than the ability for boost & pw to drop suddenly on throttle lift while the turbo has to "spin down".

Is this being done in the PIMP? And if so how do you set it up?

Thanks in advance

I'd suggest you ask this in the PiMP section as that's were Wes spends most of his time (or send him a PM).

Yeah he posted it in here so I figured this was the best place to respond to it

Thanks

That is KUWEL. I guess you could compare the turbo RPM and MAP readings to the turbo's efficiency map and see where you are on the island.
