Title: Compatible ECU hardware for wideband uprade to 1.8T A4 Post by: vtraudt on August 15, 2018, 10:19:40 AM What are suitable ECU boxes to convert 2000 A4 1.8T to wideband?
Would a 018CH work (have on hand)? Original ECU was 4B0 906 018 AA, engine code AGU (Germany). Title: Re: Compatible ECU hardware for wideband uprade to 1.8T A4 Post by: aef on August 16, 2018, 12:22:35 AM You can use alot of ecus. Depends on how far you would like to go.
8n0906018ch is BAM. You can switch of vvt, egt, and so on. This will work. Title: Re: Compatible ECU hardware for wideband uprade to 1.8T A4 Post by: dal on August 16, 2018, 04:33:20 AM I use an LP ECU with cross-flashed HP file.

Depends on how far you would like to go. 8n0906018ch is BAM. You can switch of vvt, egt, and so on. This will work. "how far": well, wideband O2, all tune outs (cat, egt, evap, sai, keep vvt?). Immo defeat. For ralley cross car, totally stripped. 67mm compressor billet hybrid turbo. pump gas (regulations), 550cc, 3" maf. Need to put a base tune on (with bench harness) before I ship to my brother (Germany). I have a tune from a tuner here, made a long time ago for this purpose. But not sure if made for the 018CH, and it if has the correct parameters (see above). Can I post the tune here and someone can check it? Title: Re: Compatible ECU hardware for wideband uprade to 1.8T A4 Post by: vtraudt on August 16, 2018, 06:06:41 AM I use an LP ECU with cross-flashed HP file. LP as in 018 LP?Are the 032 XX ECU strictly for transverse applications? For my TT225 upgrade to wideband, I have used 032 (Golf based) ecu. Title: Re: Compatible ECU hardware for wideband uprade to 1.8T A4 Post by: Carsinc on August 16, 2018, 09:11:38 PM 4B0906018CH is the ecu that is most used on a4 and passat widenband, but any wideband 1.8t will work.
Also that turbo is huge for 550cc injectors Title: Re: Compatible ECU hardware for wideband uprade to 1.8T A4 Post by: vtraudt on August 17, 2018, 06:10:18 AM 4B0906018CH is the ecu that is most used on a4 and passat widenband, but any wideband 1.8t will work. Also that turbo is huge for 550cc injectors Thanks! Can someone check if attached file is a suitable base for the wideband setup (018CH, 550cc EV14, 3" MAF, MAP?, all tune outs)? Title: Re: Compatible ECU hardware for wideband uprade to 1.8T A4 Post by: Carsinc on August 18, 2018, 10:07:30 PM i looked quick, it has been modified for injectors for sure, and some deletes, i did not have this exact def so i did not put
much effort in it.

Thanks. Is it a suitable file for an 018CH? Will try to flash today. Is immo defeat needed to swap into the car (car is totally stripped, no cluster)? Title: Re: Compatible ECU hardware for wideband uprade to 1.8T A4 Post by: Carsinc on August 19, 2018, 09:02:35 PM what ecu part number are you flashing it on?
and yes most likely immo delete will be needed if no cluster Title: Re: Compatible ECU hardware for wideband uprade to 1.8T A4 Post by: vtraudt on August 20, 2018, 05:27:41 AM what ecu part number are you flashing it on? and yes most likely immo delete will be needed if no cluster 018CH Better find someone to walk me through immo defeat procedure while I have it on the bench before shipping it brother in Germany. Title: Re: Compatible ECU hardware for wideband uprade to 1.8T A4 Post by: Carsinc on August 20, 2018, 10:44:28 PM there is pretty clear instructions up here for the immo delete

I may give it a try and/or can't find a tuner who can walk me through via teamviewer/phone. Title: Re: Compatible ECU hardware for wideband uprade to 1.8T A4 Post by: Carsinc on August 21, 2018, 10:49:18 PM i could help with that, assuming you have everything set up. but if you can read and right eeprom you have no need for help
