Hi, My WB installation: Comments from a post in 2015: "Just wanted to add some ground-info regarding my installation of spartan wb. My wb uses pin A13 (power ground) as the only ground source, no extra grounding needed. My spartan pinout: Red = A27 (power supply from the main relay) White + Black = A13 (power ground) Green = B31 (tank pressure 0-5V signal) ADX formula: (X/375)+0.68 (gives a lambda value in the range 0.68-1.36) If you want it in AFR then put *14.7 in the end. Example: ((X/375)+0.68)*14.7 Lambda values x 14.7 should be more accurate then using the AFR formula from 10 to 20 AFR." Mine is a Spartan WB controller but the pinout and adx tips might give you a hint. Best of luck. // Turboforslund

Hope this works fine: https://www.dropbox.com/s/ul288xcbcmqpzqr/0261204609_1037359880_1.bin?dl=0 // Turboforslund

I have it, let me know all the last digits. Is it 0261204609_1037359880.bin or the 0261204609_1037357528.bin? // Turboforslund

Hi, The numbers of the Bosch ECU will tell what bin to use. // Turboforslund

Hi, Will the immo still be intact but with an added logging feature for 609 equipped cars? If so, it's a great step forward! Really great news! // Turboforslund

Excellent digging! That might be it! Wonder if there are any benefits of having the OBD pin 7 going thru the immo? Interesting to see if a direct line to B36 would do it (at least during bootmode active). Hope you find a working solution this weekend! Good luck! // Turboforslund

Hi, Have you read the pages 481-483? It might bring some more knowlege or hints. I have a 850 from 1995 that do not have an OBD port at all. Maybe my own "OBD install" is a little less populated pin-wise than a stock OBD port (I do not know). Will anything like that have an influence for you as it seems to work perfect at the bench? // Turboforslund

Hi, I'm wondering if the common ground between step-up and ECU power is the issue. Have you done exactly as the instruction tells? Any difference in pinout or power supply in between bench and car? Regarding the fan. That should not make a difference if it's on or disconnected but I turned the fan off thru a relay to avoid power consumption and noise. // Turboforslund

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 completely and plug the outlet? MAF based injection systems needs recirculating dumpvalves to get stable AFR:s. I use this: https://images.app.goo.gl/Yx6P7H3Dxj3mHRoK9 Log for more info: https://www.dropbox.com/s/ihhfsor1juxlfal/2021_01_23_Test_with_and_without_supercharger.tsv?dl=0 // Turboforslund

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
