APR chip installed, have some concerns

[ardy6931]

Hey guys, i just had the APR chip done for my v10, I noticed a few things after driving it for a full day.

1. RPMs seem to stay at higher levels, when going 90-100 my rpm stays at about 4500 where it used to sit at 3500.

2. Can't feel the difference between sport mode and normal mode now where it used to be a huge difference

3. Spoiler cannot be operated error, granted this was in weather that was 100 degrees, thought maybe the engine was just letting off steam by keeping the vent open while parked.


Are these things normal, has anyone else experienced this? I am almost concerned to the point of having this taken off and going with a stasis chip

The spoiler stays up if the engine is hot and will go down when you restart the car. Why is it good to have a higher RPM at a certain speed unless you are accelerating? Do you mean that the car shifts later with the chip?

How do you get a "higher rpm at a given speed" from a CHIP????

You'd have to change either the transmission gear ratio or the final drive gear ratio....or be in a different gear I guess!... to get a different roadspeed out of a given rpm.

I had that occasional spoiler malfunction prior to getting the APR tune. It never does it at the dealer of course. Perhaps this spoiler anomaly is particular to our model & year (& color?)

I think willyjp is right, you'd have to be in a different gear for the rpms to occur at different speeds. I never had the effect you describe, just a torque boost at low RPMs and a big power boost at high RPMs.

Runs even better with higher octane. Also, dealer had my car for a few days after I'd had the APR tune. The dealer did a lot of ECU diagnostic work (replaced a post catalytic converter O2 sensor), but didn't detect anything amiss with the ECU software. Love it.

Fwiw, my '10 v8 spoiler stays up sometimes, especially if I deploy it with the switch...and then decides to come down & behave normally. (and my car isn't chipped) Will never do it for the dealer's R8 Tech either.

Thanks for the input, do you also feel that there is no difference between sport mode and normal mode after the apr install?

PM Gazza, he has had the APR upgrade done and the performance is incredible. He will know if there is a difference between both modes.

fwiw, I had a spoiler prob the other day too - fired the car up in the garage from cold, the spoiler was up and a warning light came on the dash. got it to go back down after turning it off and on and holding down the spoiler button. thought it was just an oddball glitch but sounds like it's pretty common.

APR mod has behaved impeccably since install and provided a real nice shot in the arm with performance.

I had a couple of spoiler malfunctions on my past V8 coupe but the spider and current coupe has had none at all.

I'm not sure what you mean. Sport mode only effects the dampers. Mine still changes as before the APR tune. No spoiler issues here either.
