Ok, let's hope for the best. A lot of work but it will hopefully be worth all the effort in the end. // Turboforslund

Hi, The turbo will always provide more airflow then what the engine consumes, also at idle. If you measure the direction of air at the dumpvalve hose connection it will blow out. Any measured airflow from the MAF will read more then what really enters the engine. It will be a interesting test! 😎 // Turboforslund

Hi, I belive that the closed loop control will be turned off above that value. 12.24 is the highest possible value and thereby never turned off = always in closed loop regulation. // Turboforslund

Hi, I use the Spartan 2 together with Boch LSU 4.9. I had a look at the logs and I got 12.6kg/h at idle. In the log you can see how the boost pressure is basically inchanged but the maf voltage gets really noisy (and AFR super rich). I checked my WB mod and have the exact same calibration settings as you stated earlier in your post. It is interesting that you use an "open" dumpvalve without a return hose. All the air that is measured by the MAF will not enter the engine and the engine will therby struggle to keep AFR stable. Can you try (as a test) to remove the dumpvale comp

Hi, I haven't tried the WB mod yet. I got it but have not tested it. Have you tried to plug the dumpvalve? How is it connected in terms of air-recirculation? My own issue right now is how to make stable rpm's/afr at idle with my supercharger engaged (magnetic clutch). The extra airflow tends to disturb the MAF a lot... 😎 // Turboforslund

Welcome back Midnight Caller! I wish you the best of luck with the Volvo. GT3071 will be awesome! I run a GTX3076 and is wonderful! // Turboforslund

Hi, MY 98 stand for "model year" // Turboforslund

Hi, Can it be the "TPS Angle for WOT Detection" or "Throttle angle threshold for LDR active" that needs an updated calibration? Have you checked the WG-tention? Do you run with a different throttle housing diameter with the new engine? What does TCV duty cycle, Air Mass, STFT and Injection time tell you if you make a log file? // Turboforslund

960 is motronic 1.8 i guess.

Good, I hope you know it is only pin b8 that needs +15V or so to be able to flash. All the other pins can keep the 12V supply. // Turboforslund

Hi, Can you make a full pinout of your bench-flash harness? What ecu pins is powered by + and ground? What ecu pins goes to the obd port? i.e a full pinout. What do you use as a powersource? // Turboforslund

Are you sure that the cable is ok for flashing? It might work for communication but you need the right spec to flash (I tried the "sheap ones" and it failed). // Turboforslund

I will for sure do my best as well to fight this issue as soon as my car is back on the road. I find it quite annoying. // Turboforslund

Yes! Just make sure that the load and speed axis etc. is updated too. // Turboforslund

Ask around if anyone has a LPT-adapted calibration of the rev5 bins. It should be fairly easy to get it "good enough". You have both cal avaliable in tunerpro, it's just a lot of work... 🙂 // Turboforslund
