Is the turbo chip on the same board as the map sensor?

I ask cause I want to be sure before I close up ecu!!

YES. The LDR = turbolader chip is on the lower board with the MAP sensor.

The other chip is the timing/fuel chip, on the top board.

Do you have stock or aftermarket chips?

sorry not in the topic... but 3b ECU has 200 kPa. if i wanna chip this ECU is it needed to change the 250kPa ???

Yes or the 300 kPa MAP sensor, along with the appropriate software (two chip set to make it all work).

G71 MAP sensor info (click on the G71 label in this diagram (all the labels are hyperlinks)):

Depends on the chips, std boost for a 3B is 0.8bar so you can take it to 1bar on the std map sensor, this should get you around 250bhp.

Common Steve, don't be shy. Which fuse did you forget to replace?

Someone fitted the chip the wrong way around

[stocious]

Static !

Lesson learned, started up and running on stock chips!
