	TVUB values for Bosch EV12 0280155892 269g/393cc taken from Audi TT 1.8TQ « on: November 02, 2019, 07:47:41 AM »

I can't find TVUB values for these injectors.

I think its "AMU" engine, but i'm not sure.

If someone knows them or can pull them from stock ECU, i would appreciate that. WinOLS definitions/TunerPro definitions + bin works too.

I had 0280157012 193g/282cc (blue) installed earlier, stock value for those are (on Porsche ECU) :

6,8,10,12,160
3.2840,1.816,1.1880,0.8240,0.4400

Search ASM based map locator on here. It’s a thread started by PRJ. It’ll find the location of tvub so you can fairly easily find it if you are able to get ahold of the stock file that those injectors came from.

I assume you mean "Me7Romtool". I have that, didn't work for my ECU but surely it could work for this case. Thanks for the tip.

No that is a different thing, 360's program works basically on all me7 ECU's btw. The map locator he's talking about is made by prj, should be stickied in one of the subforums.

Ok thanks, i look into that. 360's me7romtool couldn't find/locate anything at all from my ecu binary. Tried some other rom files too and none of them worked (they were all r32, vw ecus). It did work perfectly on "ferrari 360 challenge" test rom that was available. Not sure why.

I know this is an old thread but I thought I would try it on the latest (yet to be released) version of my tool. Its now supporting Volvo roms too.

Source file was 'Volvo_S60_T5_Stage1.bin'

I searched for KRKTE and TVUB.. Here's the output for anyone still interested.

All the problem was with the search mask, it was too specific. Relaxing it by masking out registers, etc. makes it work across a much wider span of ecu's. Seems to be working on tonnes of models and firmwares these days, any that I try it on infact.

BTW a workalike to ME7Info would be extremely helpful ... finding torque path and timing path RAM variables would be extremely helpful
