Let me explain the problem that i have and heard other none US spec camaros have.

Here are the conditions where the fault occurs:

1. Road speed between 48 Km/h to 60 km/h
2. Steady speed for a couple of seconds
3. Then if you press the accelerator slowly or go WOT do not matter, the trottle respons is almost zero for some seconds or until i get over 60 km/h.
It feels like the throttle plate refusing to open for quite some time, I feel that the time delay until the throttle plate actually opens is at least five seconds. This behaviour is repeatable 100%

I have heard that this was done by GM in order to pass some Euro noise emission test for the none US market. I assume its done in the calibration in some way i dont understand.

I would be happy to see someone find a fix for this. I can not see anything that differ in my pulled EURO calibration and a US calibration for the Camaro SS.

There is a cpl threads on the HP tuners forum about this but i cant see that anyone know what to do about it.

If someone have a idea where this can be found in the calibrations or how to fix it, i would be happy for some input.

I am familiar with this issue I fix it in all my Gen5 Camaro tune for Euro spec vehicles.

I do not currently know if the table is available in HPtuners Send me your tune file and I will take a look. tedj@jannettyracing.com
