Im not too sure with regard to the checksums though only one tool reports them as fixed the rest doesnt recognize it, can anybody check it if i send the file?

Just done the log,
Had to update ecu definition file as numbers where way off.

went for a good run, ran FKKVS Fixer, it cant do WOT correction but did work with WOT unticked. said cant find info for WOT, not sure what it needs as has Pedal position and at times is 100%

Everything looks great but notice STFT1 slowly creaps up to +27 after blipping accelerator it will go back to 0 then slowly creap up again sometimes sitting around+8 then +13 then other times creap up.

What causes high STFT at idle? but LTFT is spot on? ( note I checked vacuum leaks and there is non used pressure smoke tester) I do have a 350L fuel pump.


Car goes like a rocket though after it relearned boost it was really smooth. Boost rolls in steadily but one thing I did change is 4500+ increased the boost a litle so it sits around 14 then goes to 16 and around 5000rpm peaks at 18psi before it would roll off after 4500.
Fans turn on and off too. EGTs look ok. AFRS look great and very responsive soon as i go wot almost instant 12.5.  Just have to fix the STFT creap. LTFT is -0.79 and stuck there. I did put Norla back to 04 so not sure why when stft creaps up would expect ltft to go up a bit too to correct that.

Edit did second pass FKKVS STFT at idel is still high. I tried puttting LAMFA back to stock but noticed my AFR gauge was stuck on 14 again even at WOT; so it does use Lamfa map untill BTS kicks in.
I used the Bosch Green calibration chart then the Volvo KRKTE calculator for TVUB and KRKTE.

TVUB is
7.98          9.94          11.90       13.93        15.89
2.3616   1.4880   1.0336   0.7552   0.6496

KRKTE is 0.06933

Edit again. Slightly adjusted TVUB and Ran 3rd log it did sit on STFT +27, I  cleared fault while engine running and saw STFT drop to -3.48 then it started hunting with the AFRs trying to get it right then went in to + 7 then slowly went back down to 0 and now sitting and hovering around 0stft part throttle is spot on. It could just be the injectors as brand new. I tested them before putting in and all where exactly same but slightly lower flow around 412 than its stated 452cc.

Also noticed TCV duty cycle is at 95% ill give it time to settle and adjust. But would be good to sort out wastegate eg just a 4psi spring and adjust whatever map acordingly. got it set at around 3psi at moment. But think happy with tune. Live how the fan now kicks in at around 97 and turns off at 92. And now got a faint gurgle when engine rpms drop, engine is also a lot quieter than was before.

Yes, I use the older version

Can you give some more details about your fuel system? Did you replace it with return system and external FPR?

So i guess you just replaced the built in the fuel tank (fuel pump basket) FPR with new one?
Nevertheless check your idle fuel pressure. Sometimes with bigger fuel pumps stock FPR inside the tank can't keep up with releasing excess fuel pressure on idle (too much flow) and pressure in the rail goes higher then 3,8bar. Then you can have inconsistent idle fuel trims.

For pops/crackles you also need to modify KFZWOP.
Ignition is basically set with ZWOP and capped by ZWMN/MS from the "bottom" and by KFZW from the "top" (of course plus whole torque monitoring/regulating algo and many modifiers).

Well in the meantime i tried the other fw version. And it seems its not that compatible. Car wont fire up on it. So flashed it back and all is fine again. But now i still dont have defs for my bin -_-

Message me, I'll find all basic maps for you but you will need winols instead of tunerpro
