that may be the problem because it happens on full throttle (overboost). This problem was there before the chips but we adjusted wastegate before to higher boost. Do u know anyway of cheating overboost protection??? Because i may sound silly but i really wanna use the chips after the problem is solved because i trusted autodelta and gave about 400 pounds for them
Why not adjust waste-gate connection rod back to it's orginal stat,
(1mm stroke at 0.55-0.61bar and 4mm stroke at 0.64-0.75bar), to see if it helps.
I can not believe autodelta have used any other setting when they made up there chip.
About cheating overboost protection - as far as i knows the only parts of the engin management
that acts on the "real" pressure in the intake system is the FPR, waste-gate and the dump/diverter valve.
The ECU calculates the boost pressure in the intake from it's sensor readings (airflow, rpm, temp etc.)
but dosen't have any pressure sensor other than the altitude sensor, so to cheat the boost protection
you need have tools to read out data from the chip, and the knowledge how to manipulate that data.
This gives that you have to be careful with modifications you are doing between the AFM and the intake valves,
so that you not hit any limits that are built into the engin management (like boost protection), you have
brobably by increasing the base boost pressure reached such a limit when "overboost" gets into action.
If you want to elaborate more freely with boost pressure you brobably have to change the whole engin management
to VEMS, megasquirt or somthing similar, and i have heard (can't confirm this/have not tested it) that the engin
handles max 1.6bar without mechanical modifications.
(I wish it was equally as simple as on the Uno turbo, only disconnect two wires and then boost the hell out of the engin.)
Hope it is something you can use in this.
