Autopsyche has Code 6 option. Has anyone tried it on their compass? What about GT Tunerz Quantum tuning option?

I want to improve power deliver at lower RPMs.

Any thoughts on this?

Thanks,

WolfMoto used to visit Chennai and club some cars and do their tuning. you can get the details from their website or insta ID.
I am also waiting for their visit to have a discussion with them to remap my Tata Safari 2021 and their work in person.

Code6 is a little agressive.
Quantum is good for high end cars, mostly Germans and VAGs.

Try Wolf. They can custom map it for you as per your requirement.
Remap development and post remap support is exceptional.

They are visiting Delhi sometime this month. Check thier Insta.

Thanks Karthik. I will check their instagram handle. Will update if I am able to get the remap done.

Does anyone have any insights or suggestions for the best tuners for Volvo engines? specifically the older gen 5 cyl diesel ones

I've heard about Quantum providing remaps but not sure of all possible options

Finally i did stage 1 + remap (ECU and TCU) for my Rapid montecarlo 1.5 TDI DSG from WOLF performance. Post remap, the vehicle is much more smoother, shifts are faster, always runs on higher gears. They have advised to drive for a few days and then asked to give a feedback. To me, since i always runs between 1500 to 2500 rpm I’m not able to extract the real change that had made to the car. I feel like i need to get more power in the lower rpms.

There are maps within maps. Push the car hard on a highway or Dyno it and it will switch to an aggressive setting to go like a scalded cat at low RPMs. Sedate driving will again adjust the map to a conservative setting.

Woah. I didn't know this happens. Is this default for all remaps or does it need to be purposefully done?

Can you share or pm me how much it cost you please.
I have a Rapid TDI style MT, thinking of something similar in the future for my ride too.
Please keep updating about your experience with this.

All maps have this, including OEM. These adapt to driving styles for optimum performance.

Sorry, but there are no such maps in the ECU. The transmission on the other hand does learn from your driving behavior to change the shifting pattern.

Regardless of that, any time that you floor the throttle fully, you will get the max power that the engine is capable of producing at that given point of time at that particular RPM. The engine will not give you any more or less power if you have been driving like a madman or like a saint in the previous few KMs.

I know there are no "maps within maps". Just tried to convey what's going on in an easy to visualize manner!

So instead of us laymen debating now, I simply asked the expert himself- Joe of Wolf Moto.

Here is his reply-

"There is a point in what he is saying (about there being no Maps within Maps). There are no map tables that can be edited/revised.

But there are few short term and long-term fuel trim and other related dependent modeling that vary based on the way you drive (harder or sedate) based on which it make some changes. These changes are finite and will be within a range."

So yes, the ECU adapts.

TCU also, but in Manual Transmission cars, above is true too. The car is alive!

Yes, the ECU constantly adapts, but not necessarily in the direction that your driving style demands. You driving faster can cause the engine to change the fuel trims & timing to be more conservative that reduces power if the engine detects knock!

The long and short term trims that you mentioned are constantly trying to optimize the fuel burn by understanding the current health of the engine (injectors, fuel pump...), ambient conditions etc. So driving slowly will not take away performance from the engine just because the engine has adapted its fuel trim to drive more economically, and driving faster will not restore any performance. Note that I'm not mentioning the possible mechanical benefits of an Italian tune up like reduction in carbon deposits etc. This discussion is purely about how the ECU responds to the drivers inputs.

True. However, we are trying to determine if the issue of low power at low revs and low gears can be resolved in a remapped car by giving it the beans. Answer is yes (from Joe as well), that if we push the car (RPM) high enough, especially in a Dyno test, the car will come out eager to go. It works practically, the details of what's going on inside the ECU or TCU aside.

First impressions are good. Will be putting up a detailed thread with the other stuff that was done after putting on some kilometers post the mapping.

Great interaction with Jayant and the team from Engineering Exponents.

Hi Rajeevraj, how is the car performing post the remap? Are there significant gains? I have spoken to a few tuners in Pune but after going through this thread I am more inclined towards wolfmoto.
I had been driving a Vento TDI AT till September 2022 and the torque was good but since switching to Vento 1.2 TSI I can feel there’s a difference. I know that 1.2 TSI is only 175 nm and dq200 is rated for 250nm so I want to reach as close to that number as possible.

Any suggestions would be helpful.

Almost been a year now and the car is performing very well. Have not made any attempt to measure the exact gains, but the ball park numbers would be in the 10-15% range with a Stage 1.

I had put a more detailed update in this post on my thread.

Overall very satisfied with the remap and for my needs more than enough. Since Wolfmoto has a lot of focus on VW cars, I think it is a good option to go with.
