langer 5. Gang -> jetzt fehlt die Leistung, was tun??? | Posts 32+

Okay. Thank you for your effort. Now I just need to find a translation and figure out the part numbers for the gears...


Regards,
Frank.

TUEV - forget about it. By the time an inspector understands what you've done, they've already stopped the car. And how do you plan to obtain a complete exhaust emissions report, aside from the higher maximum speed?

Yes, I see that, but on the other hand: if I have Rainer do the AFN conversion to 140 horsepower, then...
I can optionally purchase a TÜV inspection report for it - they also inspect the car here.
faster, although probably only marginally.
I'm only interested in knowing how much effort would be involved in the registration process.

Greetings, Klaus.

When registering the new gears, the transmission ratio would be recalculated, and the new maximum speed would be determined. If this speed were higher than a certain value, the braking system would need to be adjusted. This would all be part of a single inspection. I don't think an emissions test would be required. We once went through this process with a VW Bus T3 that had been converted to a VR6 engine (I know, it sounds ridiculous). We were able to convince the TÜV inspector that the vehicle hadn't gone any faster.


It's clear that you'll get the tuning registered by Rainer. He's already done the work for you, and you just show the TÜV (German technical inspection agency) the paperwork. They'll check if the installation was done correctly, and then it's all good.
If you tell them that I changed the gears, it's possible that, depending on the inspection station, they might raise a red flag.
The simplest approach would be: Write down what you want to do, go to the TÜV (technical inspection authority), ask them about the possible options and costs, and then make your decision.

Thank you for the response.

Let's assume, like many others, I want to... in my AFN.
lower engine speeds on the highway, and therefore a longer...
Translation.
Furthermore, I compensate for the reduced airflow by using a (relatively...
discreet) Rainer tuning (with TÜV approval certificate).
Now I finally have my dream G3, but unfortunately, the car is now running.
faster, which the TÜV (German technical inspection agency) doesn't like.

I personally don't actually want to drive any faster than I do now.
"Tempo 200" in the G3 model is really enough for me.

This raises the question of whether the tuning affects the top speed.
can limit. Does the control unit know the speed or the...?
pickled ginger? Could there be such a thing as tuning?

Regards,
Klaus.

Hello Klaus,
The maximum speed limiter is active, even on the MSA15 (which includes all AFN and AHU models, as well as the 1Z model of the very latest generation).
Engine control units with aluminum housings (which are common in newer engines/control units anyway).

Best regards,
Rudi

Okay, regarding the gears again:

I don't want to make any advertisements here, but I have a very interesting company here. They have gears in stock (and can get everything you want), and the prices are approximately €65 and €42 (plus VAT). I'm going to order from them. I can even save on shipping because the company is only 5 km away from me! http://www.getriebeteile.com/

Best regards,
Frank.

What am I reading with my tired eyes?! There's supposedly a longer translation available for my CZL transmission?? I've been looking for a longer 5th gear for 4 years now, but I haven't found anything. My 5th generation model comes standard with a gear ratio of 0.717.
"With this, my chipped A3 210 runs at 4500 RPM."
As far as I understand, it should fit into my CZL gearbox.
I'm just asking the experts here for advice before I order anything from my supplier that I might not be able to install.
Or should I just install the 0.65 ratio gearing right away, since I plan to increase the power to around 180 horsepower through various modifications (turbocharger, fuel injection pump)?

Hi,

Yes, the translations we discussed also fit within your CZL (presumably a specific technical specification). Additionally, you have the option to switch to a transmission with a 61/18 axle ratio (e.g., DEA, DQY), or to modify your existing transmission to a longer axle ratio (61/18; 60/19), since you currently have the shorter 62/17 ratio. However, changing the axle ratio is not a trivial undertaking.

Best regards, Frank.

Thanks, Frank! But unfortunately, it's too late. I just ordered the 0.659 gear pair ;o).
I'm so curious to see the result, as I've been wanting to install a longer 5th gear for a long time. My CZL comes standard with a 0.717 gear ratio, which means the jump in performance won't be too significant.
A complete translation would be the better option, as it would also allow for optimal gear ratios.
And even better, of course, would be a 6-speed transmission. But that remains to be seen.
By the way, I also ordered the smaller spring plate for the smaller gear at the same time.
There shouldn't be any complications.

So, I'm wondering what I would do without the internet.
The information you can find, especially on this page, is invaluable!

Well,

You will definitely notice that it makes you 8.8% taller.

I'm also curious to see your results.
It would be great if you could take speedometer readings before and after, like in this example:
http://www.wiesestefan.de/getriebe.htm

and of course, air exchange rates in room 5. Something like 140-160 km/h before/after.

Thank you for the tip.
I will definitely document this, as storing the file in my "gray cells" (i.e., my memory) is not a permanent solution.
Good page overall.
