there is more to the dtc disabling than it seems. i have tried too but only managed to get the cel out of the historic, it is still listed in the current though. need to some more dissasembly.

Why not move the CAT efficiency range to meet your needs rather then trying to kill the CEL itself? I know I mentioned this before...

the p0420 is not the only code people are dealing with lol. my cel just came on this am on the way to work so don't think my fix worked @ all unless its a new one.

^^^ BUMP ^^^

Any progress made on the code elimination process. Just installed TGV deletes, need to kill off the codes being thrown:

P1086 TGV Position Sensor 2 Circuit Low
P1087 TGV Position Sensor 2 Circuit High
P1088 TGV Position Sensor 1 Circuit Low
P1089 TGV Position Sensor 1 Circuit High
P1090 TGV System 1(Valve Open)
P1091 TGV System 1(Valve Closed)
P1092 TGV System 2(Valve Open)
P1093 TGV System 2(Valve Closed)
P1094 TGV Signal 1 Circuit Malfunction (Open)
P1095 TGV Signal 1 Circuit Malfunction (Short)
P1096 TGV Signal 2 Circuit Malfunction (Open)
P1097 TGV Signal 2 Circuit Malfunction (Short)

which car ? DBW or not ?

The DBW cel solutions are posted in the previous page and work fine... it didn't seem to work originally cuz the ECU checksum wasn't being updated properly...

non-DBW, not sure...

Non-DBW, just started another thread about pulling a full 192K ROM image from a vendor flashed ECU, looks like they have extra code beyond the 160K limit that takes care of disabling sensors.

thats actually an enginuity thing i believe. have u taken a look at the stock version of your ecu?

Bump! Anyone have success on non DBW eliminating various codes like TGV?

Very interested in this as well......

I do believe the 0/1 table does work on the DBW ecus. I haven't gotten a P0420 code since I flashed the fix in. I would imagine it will conceal the TGV codes just as well.

Yea but same for non DBW? Anyone already locate this table to prevent reinventing the wheel?

I thought CEL disable for non-DBW had long been established. Overwrite 0500 or something like that over the code?

Seems that gets rid of the light but not the code so it will still show up in a scan. I want to eliminate the code entirely.

bump me too

I don't know if this can help but on a USDM WRX A4SGA00C,

disabling the P0302 in HEX 2E4B5 to 05 00 00 didn't get rid of the fix, the CEL still showed up after a few minutes (I too have a flywheel that throws misfires.. and raising the threshold to 15 didn't fix it).

This region of rom: 2E4B1,5,9,D seem to be the right spot but the CEL still show anywayz....
