At last, after a lot of deliberation, finalised remap with
Pete's. Options were between Pete's / Code6 / TOT. Selection was primarily based on the following criteria:
1. Pete's experience with
VW 2.0 Tdi remaps and reputation as an established / dependable company.
2. Pete's uses map from
Malone-tuning for VW 2.0 TDI; These maps have good reviews and
verifiable.
3. Remap offered by Pete's appeared like a
finished product with fixed specification (time tested), unlike others which were heavily customised. As I am a common user with
conservative mindset, I was rather discouraged by these excessive customisation option.
4. As this was my first remap and as I did not have previous experience with remaps, I was cautious and opted for the safest option available.
Map Specification:
Stock rating of Jetta 2.0 TDI is 138 bhp Power and 320 Nm of Torque at wheels.
Remap will boost it to 184 bhp Power and 400 Nm of Torque at wheels! Link: http://www.malonetuning.com/20l-cr-tdi
I expect this to be detuned to 177 bhp Power and 380 Nm of Torque at wheels, in order to meet our fuel and environmental conditions. I plan to
dyno the car some-time after remap.

I was given to understand that basically fuel intake / turbo boost / fuel to air ratio / EGR valve timing, will be varied to obtain added power. Individual driving pattern will be acquired through ECU logs and referred during coding. I have given my requirements as follows:
- Strong bottom end to enable lesser gear shifts.
- 6th gear to pull from 1200 - 1300 RPM.
Note for AT users: Although AT uses the same MQ350 as in MT, AT gear boxes contain heaver clutch plates than MT. Therefore, AT can be tuned for a higher torque that the MT. But since torque is digitally limited to 350Nm by the DSG CPU, any remap will logically require the DSG software to be upgraded. This upgrade will enhance the torque limit as required. Otherwise, DSG will not synchronize with the engine torque delivery and can result in shift delays at
higher torques.
Implementation: ECU is Tricore and anti-tune protected, manufactured by
Bosch. These ECU’s contain special programming incorporating a 1024 Bit RSA signature to detect non-genuine software. A hash check algorithm checks the validity of the software being installed, meaning that this ECU type can permanently lock preventing the car from starting, especially after attempting to flash them over the OBD. To get around this stumbling block, the ECU is programmed on the bench, bypassing the anti-tune protection.
On bench flashing requires the ECU to be opened-up and the EEPROM be flashed directly. However only temporary connectors are used and soldering is
NOT done. After the ECU is flashed on the bench for the first time, any further flashing can be done through the OBD.
Right now, car is parked at my portico; ECU alone was removed and taken for the remap. Hopefully, I will get back the ECU by Thursday. I should mention that the service extended by Shibin is excellent.
Care to be taken after remap:
1. Oil change Service schedule to be reduced to 12,000 Kms.
2. Air filter to be cleaned / changed every 6,000 Kms.
3. Frequent hard launches to be avoided.
4. Frequent / Extended WOT (wide open throttle) to be avoided.
5. Car to be driven gently, until the engine reaches operating temperature.
6. frequent short trips with a cold engine to be avoided.
7. Must: 30 secs idle at cold start and 60 secs idle before the engine is turned off.
8. Minimise RPM, to minimise wear and tear.
Following VCDS updates are planned after remap: (Free add-on service from Shibin)
03 - ABS/Brakes: (Assist high, XDS high, DSR high, BDW active)
09 - Central elect ( Anti-theft active, Headlight dimming inactive, Tear wiping active)
17 - Instruments (Staging active)
36 - Seat mem drvr (Easy entry active)
44 - Steering assist (Torque steer compensation active)
56 - Radio (Development test mode active)
77 - Telephone (Sort by first name, 3 button keypad active)
- Lane change indicator to be set to 5 blinks
Roof buttons numbers to be changed. (If possible)
Information - 008008655792436 - To be changed to 1800 102 0909
Service - 00800897378424 - To be changed to 1800 209 0909

I am planning to get
Castrol SRF brake fluid for the Jetta.

Also, I found this "AFE Stage 2 Si Cold Air Intake with Pro Dry S Filter
" interesting - This is a direct OEM fitment and contains dry fabric based (oil-free) reusable filter. Any suggestion will help.
