I feel your car may come clean at a different PUC center !!

I tried a different one the same day. He entered the details but couldn't proceed as his software displayed that the vehicle has failed the test. He asked to come the next day.

Now, interestingly on the next day, he very categorically asked me to get it done without actual testing as the vehicle might fail again to which I agreed. He did it without testing and voila, it was done (charged me a little premium for this ) !!!

Wow! I guess Ford has to do some tuning at their end to comply with the PUC guidelines. I faced similar trouble while getting this done last year.

I have made a note of it and will surely take it up with Ford Service guys on my next visit.

I read that the BS6 update might experience a slight drop in FE. Next 2-3 tank full readings can be observed to certify the same.

I did have this excess black smoke issue in my Freestyle (2018)

However, in 2019 Dec, during my annual service EUC update was done and this problem vanished

I never felt any drop in performance / FE so far

I was like His submission was that this happens at times with diesel cars, more so with Ford. Also, asked me to get engine tuning done and come back again. I left without any further conversation.

Try a different PUC center. I had the same issue with my Ford Freestyle T+P. Tried a different one. It passed with flying colors. Still if it fails, welcome to Faridabad. You will get a PUC for one year without any test. The charge may be slightly on a higher side. Says a lot about our ever so-efficient system.

That's a nice move by Ford to solve the issue of excessive smoke.
I own a 2016 model Ecosport 1.5 Diesel(100ps variant) Titanium+ which has got a Stage 1 ECU performance Remap from Code6, Bangalore.EGR delete has also been done.The smoke levels were almost the same even when the engine was in its stock form.But even now,after crossing 3000rpm,the smoke levels are on the higher side. I'm not planning to get this issue resolved from the dealer as the mapping might get it back to stock. Should I get this rectified from Code 6 and will another mapping in the ECU reduce the smoke levels? A detailed explanation would be appreciated 😊

I got my BS4 Figo 1.5 diesel serviced on Monday. While driving back home, I felt there's a difference in which power delivery is now done. Engine sounded smooth and silent. But initial surge of power has flattened. I was wondering what could have been done to change the way engine responds. After reading this thread, I contacted my SA and he confirmed that there was indeed an update to ECU.

Question to fellow Ford diesel owners- has anyone felt that the power delivery has been affected after the ECU update?

[Viraj.515]

I got the PCM firmware of my Freestyle 1.5 TDCi updated 10 months ago.

What I observed?

• Reduction in smoke by almost 90%
• Reduced diesel clatter to certain extent
• Engine felt smoother on pushing
• The raw madness on offer by the 1.5 TDCi is missing. The power delivery is more on the linear side.

I personally wish to get back to the previous map. I genuinely miss the raw madness.

You need to check if Code6 has a map that reduces smoke. When I was running their Stage 1 map, my Aspire used smoke a lot when revving high. It reduced when I moved to a Wolf Moto map and reduced further when I got a newer map flashed to reduce smoke. Now apart from a puff of smoke just before the turbo spools up, there is no smoke any other time.

Old Ford Endeavour, the one with spare wheel at the back, puffs black smoke on acceleration is commonly seen on the road.

CRDI engine has MAF (mass air flow) sensor that measures amount of air delivered to engine. Based on that input of MAF sensor, ECU decides the amount of fuel to be injected in the engine. software update may be recalibration of MAF sensor data. But why only old car puffs smoke? and whey not new car? is a mystery.

I just got the PCM reprogramed as well yesterday, after raising the issue with SA for black smoke.

I second you on the power delivery bit. The sheer explosiveness from the earlier tune is somewhat missing. The throttle response is more controlled and subdued. Its not MAD anymore!

This gets me thinking - can manufacturers alter rated power figures (advertised during model launch) in factory mapping updates? I feel this update is not just change in power delivery curves, but also its values/figures.

I guess only a dyno will prove otherwise (else?).

The good part - the smoke, finally has remnants of a more combustible nature. Thank God!

I have a 2016 Figo and Ecosport. Neither of them have a smoke issue. Is this problem only there in recent model year cars ? Or am I missing something

I hadn't noticed the smoke issues in mine until a cousin of mine pointed to me when he was riding his bike behind me. It is only when you floor to get accelerated and stops once the rpm drops.

Fair enough. I never floor the accelerator usually. If I do I always look at the RVM's for smoke, never seen any. Thanks for your response 👍

Hey SddHnt,

Have sent you an email seeking few details. The PM option is not available for your account as of now.

Do you feel it is worthwhile to get the update done since the driving experience has a noticeable difference ? Does it spoil the fun factor attributed to this motor to that extent?

I noticed the same in mine in a very similar fashion apart from noticing the same at the PUC center!!!

Precisely the reason you haven't noticed any yet.

In no ways it's a slow car, but I genuinely feel that the initial rush of power is missing and the fun is gone with that. But it's still chuck-able in highways.

Depends on which side you'd want to trust-fall over :

A face saver and reassurance of not being poked by everyone for your obvious indifference towards rising pollution, air quality, nature, global warming etc etc.

OR

The reassurance of never really looking back while ogling on every bit of the sudden and relentless torque (typical TDCi), while leaving the folks guessing between dust and smoke!

Personally, I'm happy and willing to let go a little, as I had been nudged way too many times, all the more so, as my car is just over an year old. I was fed of justifying the world about engine architecture, combustion and the stuff!

I'm still yet to take her out on a long sprint since I got her back the-day-before. Heading out for a road trip to the hills soon. Hoping for some more pleasant surprises!
