Sorry it took me so long to put it up but here it is:wink:

the second run i lost power:iono: Guy said its probably because it was hotter in the bay:frown:

Well time for you guys to pick it apart.

The first half is HP/Torque vs RPMs right?

looks like vs. speed to me -- never seen that before, only rpm's

the famous AFR , its pretty steady but once you hit that 90mph its starting to get thirsty (i.e injectors are close to the max or the ECU is cutting off fuel slowly IMO).

That's because of the engine cut off not because is running out of fuel....

It would be really bad engineering from Toyota if the car ran lean at the red line...

Is just the rev limiter kicking in.

It seems pretty normal, just like any other NA Yaris.

It looks like you have a nice set of mods to pull 105 whp... that or the dyno is a little off...

Any ways, nice number :thumbsup:

well i would hope it would be accurate.
AFE intake, DC header, TRD axleback, NST UD pulley... ehh that about it really as far as performance.
But to tell ya tha truth it feels alot slower than 105whp lol.

MT or AT?

Your dyno guy may still have the raw data in his computer to give you a graph vs. RPM

First time I dyno'd. the guy gave me a printout like yours so I asked him to print one using RPM for the X axis.

Looks pretty nice to me, AFR's look real good too. :thumbsup: Don't see anything wrong with it. Were you hoping for more hp?

the famous AFR , its pretty steady but once you hit that 90mph its starting to get thirsty (i.e injectors are close to the max or the ECU is cutting off fuel slowly IMO).

AFR from about 5000rpm to redline is right where you want it for max power. :wink:

That's a worthless dyno graph.


HP to RPM is the only one that counts.
