How do you think your brio now stacks up against your gt tsi?
Would love to see a drag race or a roll on race.
I honestly think 5 years down the lane, you should turn this into a proper project car. Back seats out, roll cage in, sticky rubber, Blisteins and brembos, Headers and exhaust and all. |
The performance numbers were on an empty, open road. I did go for it half heartedly, but I was worried about cars around, so I didnt really give it all the beans.
The gearbox of the City and Brio are the same but the ratios are different. The final drive ratio of the Brio are shorter than that of the City. This doesn't change anything except for the fact that 5th gear feels slightly shorter than normal.
I drove the Honda and the Polo back to back. The thing is, the Polo is overdue for service, and she has been feeling a little 'heavy' since a few days. The Honda definitely feels more sprightly than the Polo as of now, since the naturally aspirated engine has no lag at all. I
I can't really do a proper project car, as this one is to go to my mom and I am to get a Laura RS or something equivalent when my accountant allows me.

Can you tell me which OBD scanner your using and from where you get it. |
Any bluetooth enabled ELM327 scanner on ebay will do. If you have an iPhone, you need a Wifi Scanner.

Haven't had any issues with it after multiple maps and long runs! Worth the money IMHO. Happy driving |
I am thinking of a piggyback purely because a standalone ECU for a drive by wire vehicle is a PAIN to tune. I don't need the ECU to do anything other than control the ignition timing and fuelling as per the 1.5 engine. The speed limiter on the stock ECU cannot be removed. The 145 kmph limit remains.

You said this can be done in the Jazz too? I have my doubts, the Jazz has a very tightly packed engine bay. I don't think it will be accommodate the bigger engine. How much is the size difference?
Also, if you feel that the current ECU is adjusting well to the new engine, i don't see the need to upgrade right now. You can do it later to extract more power out of the beast. Will put a grin on your face again. But, this is if it is idling properly and starting without accelerator. If its not, I'd advice you to get it fixed soon. There might be incomplete combustion happening and it will lead to a lot of soot deposits and hence reduce the life of the engine. To confirm this, get an emissions test done. Compare the results of the normal City engine with what your car is doing. If its within limit, i don't think you have to worry. |

The 2 engines are EXACTLY THE SAME. In dimensions, in their mounting points and their intake and outlet ports. EVERY thing is the same. So if this engine is in the Jazz, then you can interchange it freely.
The new Jazz and old Jazz have similar engine bays and come with the same engines.
Also, the 1.5 engine has been shoehorned into the new and old Jazz all over the world. Check youtube.

The reluctor ring (Sensor plate) that the Crankshaft Position Sensor detects, before providing the spark signal to the cylinders was different in both engines. I had to interchange the plates. Matter of half a day!

Considering that you want this to be an everyday driver I'd suggest you go for the stock ecu of the L15A . A no nonsense solution instead of having a piggyback ecu and tuning it . The motor by itself produces more than adequate power for a little hatch .
On the other hand , if you want to make this a proper Hot Hatch , then a piggyback would be the way to go. |
Stock ECU won't fit. Different harness. I would have preferred having that Keihin ECU. It is even easier to tune that ECU. But sadly, I have the Motronics model.
