how does the ECU know which gear you are in if your car is manual??? On my '02GTI 1.8t AWP HS box/o2j tranns there are no sensors going to the tranny except for the reverse light nor sensors connected to the gear shifter inside the car. Please explain.

May need to change NVQUOT-- if change box/ratios
But if use VCDS and meas blocks notice picks up each gear very quickly

Good to know as I have the parts in my shed to put together an 02j trans with a 4.23 ring and Eurospecsport close ratio gear set with .81 5th. just need to do it ha!

Which measuring block number/s or you talking about. I would like to see this for myself!

Thank you for your input Vdub-dub!

Seems pointless to leave the post I did to start a thread that had already been started. so its cleaned up even more now. wow the words can glow...this is about useless but for some reason entertaining. I guess it's the simple things...lol

There's numerous threads on this topic.

Use MDBGRGA not KFMDBGRG, unless you like wonky timing

I was going to link him to it until I noticed he was posting in there, so obviously aware of it.

Can anyone answer my question to Vdub about the measuring blocks in VCDS? I checked the Ross-Tech site and didn't find anything about this.

When first time looked at MDBGRG definition I thought there should be no difference between influence of these two tables to timing.
Then I've noticed mibgr_w which goes from KFMDBGRG into MDKOG function.
Is this the reason why KFMDBGRG table is not preferrable? How exactly does it change timing, just reduces when it hits the limit?

When I tried it I ended up with very crippled timing... it was very low.
So now I'm going to use MDBGRGA

check

Alfa Romeo 1.8TBi 200hp file and you will see how Bosch makes boost per gear
Also in 207 1.6THP there is the 2nd gear torque limiter, you can learn from this also

It is an excellent feature that Bosch includes in Motronic software but requires a perfect calibrated torque model and not the
300% IRL - 100% IOP - 300% LDRXN
