Something from the 90hp front: Acceleration times with 10 cent coins

Hey everyone!

I'm interested in the intake and exhaust timing specifications for the 90 hp TDI engine.
With or without tuning!

I have my times (AHU, 07/97, 1500kg (m. Driver included and full tank), sedan, 160,000 km (approx. 100,000 miles), previously stopped here.
'For comparison:'
3. Speed, 2,000 - 4,000 RPM.
Series: 9.31 seconds.
with 10 cent timing: 6.93 seconds. (Thanks to the diesel tuning community for their help!)

Can we somehow derive the additional performance from this?
I simply calculated the percentage ratio from that.
and achieve a 25.5% increase, or approximately 113 horsepower starting from 90 horsepower.
Am I approximately correct with my calculation?
I would appreciate it if you could provide me with some benchmark times!

Happy Father's Day!

Andreas.

Hello Andreas,
Do you mean the 10-cent adjustment for the fuel pump connector or for the boost pressure?

Best regards,
Thomas

Hello again!

I performed the 10-cent tuning on the pump cable (pins 2 and 3).

Andreas.

What is the resistance value of your resistor?
I used a 1k resistor in mine, with a switch inside. I tried a 910 Ohm resistor as a test, but it seemed to cause more black smoke, so I felt more comfortable with the 1k resistor.
I'm going to try to measure a reasonable time: 3. Is gang 50 to 100 correct?

Best regards,
Thomas

Okay, here's the translation:

'Also, another thing: 1Z engine, manufactured in 1994, for a Passat Variant, with tire size 195/60/14.'

Best regards,

Hi Thomas!

The resistance value I'm getting is lower than the values previously reported here.
'I have 450 ohms set (and it can also be switched on via a switch).'
The motor starts to stutter at 300 ohms.
The values 670 Ohm, 820 Ohm, and 1 kOhm did not result in any increase in power output for my motor.
However, I have a slightly uneven idle.
I haven't noticed any increased soot buildup (although I've been using a K&N filter in the airbox for about 50,000 km).
Tires: 195/65R15

You can quickly calculate this using the Excel calculator available on Rainer's website.
First, enter all the data for the normal operating state and adjust the speed (e.g., to 2000 rpm) and/or weight until the stock (or standard) value is calculated.
Then, enter the "Engine Power Increase" value so that it matches the tuned time.
"Under 'Effective motor power'," the calculated power output after tuning is displayed.

One more question: Did you install the version without or with diodes?

Hello Andreas,

Something is wrong with your values.

My 1Z G3 station wagon weighs 1430 kg with me (82 kg) and a full tank (1195 kg according to the registration document... haha...). Or are you talking about a Passat?

By the way, my transit time is just a little over 8 seconds without any modifications.

Best regards,
Bertil

Hi everyone!

I drive a Passat B3, with a curb weight of 1370 kg according to [source]. License and driver:
82 kg. + full tank (estimated 50 kg).

I haven't tried the tip about the diodes yet, but I'll definitely test it out soon (to smooth out the idle).

'I'm having trouble with the Excel spreadsheet. I downloaded it, entered my data, but it's not calculating anything (although I also don't have the torque values for the individual speed ranges).'

Yesterday, I was driving on the A7 highway with a caravan (1000 kg) and, while merging into traffic, I accelerated with the engine tuning (*wink wink*) -> I saw some black smoke for the first time, but it pulled a little better – right?
'Happy are those who one day will be able to afford a V10 TDI.'

Best regards and have a good weekend.

Andreas.

Hi.

I think I created that table in Excel 2000...

The table itself calculates the torque values above 2000 rpm and presents them as a suggestion.
If you copy the values from the "Calculated Torque" column into the yellow column, you get a kind of universal approximation based on the curvature of the AFN curve.

My old 1z takes approximately 10.5 seconds in its original condition.
Is something broken? Or is it possible for there to be such differences?
10.5 is third gear on a 2000-4000.

Hello,

So, a Golf3 1Z should be able to achieve a 0-60 mph time of around 9.5 seconds without any modifications (and the sedan version should even be a bit faster).
At what mileage did you perform the test? What did the fuel injectors look like?

@Bertli,

Hey, have you had your G3 Kombi weighed?

Can you tell me, in this case, what 'enhanced' equipment you have on board?

If you scroll up a bit in this thread, you'll find the answer... (1430kg)

"The registration document states a weight of 1195 kg (although this is also listed for the sedan version)." The specified weight is the ideal, lightest weight for the (simplest) basic equipment configuration when fully fueled and with a rider (75kg).

I think the combination is about 80kg heavier than the limousine. The entire air conditioning system weighs approximately 30kg, the radio and navigation system weighs about 7kg, the 4 doors weigh 30kg, the sunroof weighs 10kg, the central locking system weighs 5kg, and the extra weight of the driver is 7kg.

If you add up all the small items, the total weight quickly becomes surprisingly high.

The TÜV (German technical inspection agency) always says, "Don't be disappointed if the measured value is very high." They know that the values listed on the vehicle registration document are often much too low. We discussed this a long time ago and concluded that the values specified on the label are difficult or impossible to achieve.

By the way, my 1Z has been gone for 6 weeks.

He has driven 220,000 kilometers.
Is it due to the mileage, or is something broken?
