Title: ECU parameters database Post by: wachu on November 25, 2021, 07:20:25 PM Hello,
How can i verify which ME7.5 ECUs can i use for my 1.8T BAM wideband build? For example i've found this ecu which is cheaper and in better condition than 8N0906018.. (https://i.imgur.com/QOVnxwh.png) Can it be used in my case? If not, is there any list of ECUs and their parameters? Thank you in advance Title: Re: ECU parameters database Post by: tadope on November 25, 2021, 08:02:42 PM Since when do ecus have good or bad condition. They're totally sealed up.
Anyways. Ecu cross compatability is a tough one. Luckily a lot of wb ecus work together Title: Re: ECU parameters database Post by: wachu on November 26, 2021, 06:03:41 AM Since when do ecus have good or bad condition. They're totally sealed up. Anyways. Ecu cross compatability is a tough one. Luckily a lot of wb ecus work together I meant some of ECUs looks like brand new while other ones seems like they've been laying down under the sea for 20 years.. I know its only visual aspect but.. What do you mean by WB? Title: Re: ECU parameters database Post by: Sandstorm3k on November 26, 2021, 06:20:27 AM Just get whatever transverse (wb= wideband) ECU. It will probably cross-flash without issues.

It will run the car tho you wont have closed loop lambda, and a few other things Title: Re: ECU parameters database Post by: wachu on November 26, 2021, 01:02:28 PM Thats a 2l 8v ecu, its not 100% compatible. Its missing hardware the 1.8t ecu has. It will run the car tho you wont have closed loop lambda, and a few other things Thank you very much. I finally bought 8N0906018H BAM ecu. Should be fine. Now i am confused with wideband conversion. I will have BAM engine with VVT equipped and i think i need to add wires to the VVT solenoid as well? As i see that aftermarket wideband conversion kits has some resistor added for non-vvt engines. Is it necessary in my case? Or shall we just disable VVT afterwards?

Title: Re: ECU parameters database Post by: Sandstorm3k on November 26, 2021, 03:29:50 PM Just run two wires from the lambda to the ECU, saves about 99$ on this way to expensive conversion cable.
Also you can add in VVT too.

Also you can add in VVT too. Yes, but i need to connect VVT solenoid somehow as my main harness is from AJQ engine. Also i dont see VVT related pinouts on ME7.5 pinout, please check: https://img.photobucket.com/albums/v452/tsuter/APHMotronicpinouts4.jpg Thats why i've asked. Not sure if it should be connected directly to ECU or in different way Title: Re: ECU parameters database Post by: wachu on November 26, 2021, 06:35:54 PM Yes, but i need to connect VVT solenoid somehow as my main harness is from AJQ engine. Okay.. So it took me few hours but i think i've got it. It seems like the VVT solenoid is controlled by ground signal from ECU PIN 115. The second wire going to solenoid is 12v. I hope it is correct. Title: Re: ECU parameters database Post by: tadope on November 30, 2021, 07:46:30 AM I just did that conversion on an amu engine.
What engine are u putting that ecu on? Basically you can fix any differences in software. Things i had to fix Egt Vvt Maf Injectors O2 delete rear Cat delete |
