I have buy a chip from a guy on Ebay the name on the chip is TT techtronics, and it give about 23ps more.
My question is.
When i install the chip the rpm of the energine is go up and down (700-1200) and i shall just push a littel bit on the gas pedal and the energine go 2-3000 rpm and the rpm is also go a littel bit up and down here ??
And the bord computer show somtimes 0.0 when i tray to drive with this chip install.
What is wrong ? i have install the originale chip again and now is all ok again.
The guy i buy the chip from asked about the Motortronic number and the number on the originale chip, and i gave him the number (i knows ther is a different box / chip type).
Question 2.
Is ther other parts ind the energine ther shall be justeret / calibreret when i install the Tunings chip ?
Best regards
Sören

I think you have the Wrong Tuning Chip ! Normaly you just change the Chip an Everything works fine ! There´s no need to change other parts of the car. The Tuning is only on the Software side, this means the engine becomes a chip with a updated ,,Firmware,,. When you have the Wrong Firmware you have Problems... (like the BIOS from a Motherboard if you flash the wrong firmware it doesent work).
