Hello guys!

I have here my own car which i wanna tune a little. I wanna max top speed and little more power and torque.

this car can't been tuned with remove chip

[fruti]

I flash via boot mode ... Galetto. I don't remove chip. U can't flash via obd .... ME 1.1 i think :)

Hello
You have to flash via OBD only! Eeprom checksum will auto-adapt only on this way. ECU is MEG1.1.

Hey mate .... can you please explain how i can flash via obd if this is not possible ?
Do you know any other procedure witch i don't know ?

[filecloud]

Why should this be not possible? Where is your problem? Every crappy clone tool can flash MEG1.1 through OBD port. Look here in forum. There is nothing special and there is no trick.

Yep ... it is working :) Everything OK with flash BUT ..... After 5km it is falling in to LIMP mode. Turbo pressure drop. DTC pressure deviation .... What did i wrong... ?

[nick_f]

check your tuning file again,maybe to boost or some limiter forgot to tune?

[kennfeld]
