Without the UNICHIP installed, you could check your fuel trims with an OBDII scanner to verify that you're out of injector.

I guess I don't understand but I thought/think the Unichip controls the fuel flow. You can adjust for rich/lean. Is this not a matter of optimizing ?

Clueless in Atlanta.

The car does run pretty good but you can tell as your going through the rpms that changes are happening.

 

The fuel trims can indicate the fuel added or subtracted required to bring part-throttle (closed loop) driving back to the mapping based on the narrow-band O2's RMS deviation from stoich, however fuel trims are not used during open loop (full throttle) driving with narrow-band O2's. Using a wideband O2, you can interpolate you're "out of injector" based on the injector signals versus the ability to keep the A/F where you want.

 

Spidy,
There are some generally accepted guidelines for optimum a/f ratio but the point of custom tune would be to throw that out the window and tune for your vehicle. Major modifications that alter your engine's efficiencies can change what your target A/F ratio is. Good luck!

 

At this point I am going to drive the car to Birmingham and tell them to make power and try not to blow it up....I have to get home and I don't want to take the bus.

 

it has been pointed out to me that DSC need not be turned off to make a dyno run...it will turn itself off when no rotation of the rear wheels is detected and the fronts are pulling a load.


this is different from breaking the front wheels loose at the drag strip, which with DSC left on, will throttle back the moto, planting your nose in the dash.

 

It doesn't throw some sort of error code and go into a limp mode? Interesting. How does it tell the difference between the dyno and the dragstrip?

 

Ok.....I'm at 190.2


I think I should be at least 200.



This may be a case of addition by subtraction........ We'll see after Thursday.

 

If the rear tires don't turn for a "very" long time, the DSC turns off because it's confused. At the drag strip, the rear tires turn as you move forward, I hope.

 

I GUESS you're right.
