On Fresh alloy somewhere a guy had a few dynographs posted of his S13 coupe twincam. He had returned the car to stock and was dynotesting each upgrade..

Of course his first stop was to basic maintence.

His torque curve is nothin till around 4K rpm and then it jumps quite a bit higher but is never where it should be.. At the higher rpm's it moves a lil better, but comeon, first and second gear my singlecam would slaughter it from a 2Krpm roll...

Reason I bring this up is that I feel my twin cam is lethargic, particularly in the lower revs (sub 4000) as well as I have cooling system issues anyway.. Do you think that this sensor would have the same effect on me as it did this other guy?

I'm thinking of throwing it on the dyno to see if my chart has that "Vtec" like power spike, and when freshalloy comes back online I'll post a copy of the charts from there for you to see..

 

do you have any mods on your twice?

 

nope...

Theres an exhaust but i'm betting that its a cheapo muffler on the stock piping, its quite quiet, so i'm guessing its real cheap

 

Here is the dyno i'm referring to....

Here is the thread

 

Interesting......because whe n Ifirst got my car it had a CEL for a bad Coolant temp sensor and a bad primary 02 sensor, but I took it up to Autozone and had them reset the ecu. ANd have yet seen the CEL light come on. I wonder if I replace them if I'll notice a difference

 

cool shit...mattback...maybe we found your problem?

 

my car throws a 55

 

I know this car also threw a code. but I dont know what that code was, its in the therad i believe..


DO ya'll think this is my problem?
