Title: 1.8T APY/BAM EGT delete Post by: IAmAnEngineer on October 07, 2020, 05:52:04 AM Hi,
a friend switched his 512kb APY Me7 to a 1024kb BAM Me7 with wideband lambda, because of a BAT. Everything working fine so far after removing VVT etc. in the software. EGT is removed by CDATR CDATS CATR = 0 But when looking in block 112 with VCDS, the ecu still corrects the injection by the (non-existing) EGT sensor, the engine is running way too fat (idle lambda 0.75). Target Lambda in Block 31 is way down to 0.60. Offsets are 100% correct, injectors and maf are stock for "running-in" the engine. Everyone had such a weird behavior? Maybe some wiring fault?

Use a 180 wideband tune and port your calibrations Title: Re: 1.8T APY/BAM EGT delete Post by: BlackT on October 07, 2020, 12:03:14 PM TABGBTS set it to 1229

I am not sure, will look tomorow to confirm Title: Re: 1.8T APY/BAM EGT delete Post by: prj on October 07, 2020, 12:49:35 PM Learn to log, and you will have the answer.
But most likely the offsets are wrong, or you messed up something else. If those 3 codewords are done, then ATR has no effect on fuel.

@prj: I know, I always disabled it the same way and it worked fine, offsets are 100% correct, file in attachment. ??? Title: Re: 1.8T APY/BAM EGT delete Post by: dream on October 17, 2020, 03:37:34 PM Have done the same switch from APY K box to BAM H box and coded out the EGT as founded on the forum here and never had any issues.
Altough shifting up TABGBTS 1229 doesn't sound like a great idea, cause it will be harder to reach the treshold. |
