How "smart" are our PCM's ?
I had my car dynoed, and noticed 2 things:
1) The HP was lower than I would have expected
2) The A/F mixture is very RICH on the upper end
(This info per Hypertech, BTW - I emailed them. The lower the number, the richer the mixture. Makes sense when you think about it - 14 parts Air to 1 part Fuel {14:1} is leaner than a 12:1 mixture.)
In any case, I have free ram air & love
to floorborad the car @ 70 for the kickdown & the rush of acceleration helped by the FRA.
So, the question is could my computer have learned that WOT = a leaner condition (due to increased air flow while moving ) & made an adjustment to the lookup tables to fatten the mixture ?
At a standstill (ala the dyno ) this would cause a rich condition & may have affected my peak HP output.
??????????????????????
Here's my post about this in case you wanna see my weak azz #'s.

from what i can see your numbers aren't off by much if you have no mods except the hypertech i would ditch the hypercrap and try again no offense but the hypertech is worthless not worth the plastic it's made out of.
Well, it's gotta Borla ...

Plus FRA, TPS, EGR , 2800 Stall, MTI lid, K & N , & the fan settings optimized for the 195 thermostat.
So there are a few goodies on there !
The prior owner had dynoed it @ MTI and got 316 - I would have been happy w/ that.
Trick is, I don't know what was on the car when that number came about, nor do I know how much power a stall converter really takes out of the system.
I may have to try it agin w/o the HPP3 power programming on , but still am curious as to the system IQ !
Thanks !

since when do computers think? hehe
they do run a closed loop feedback system.. although I think at WOT it switches over to open loop?
Maybe someone that actually knows a bit about the comptuers can answer this,.
