Drive on,

The wiring harness is different. I was just doing the math.
A used ECU with a wiring harness will cost around 20k.
Immobilizer will have to be programmed to accommodate the new ECU.
And then, a tuner will have to be paid to tune the ECU (maybe 30k)
So 50k will be the investment just to get a used Honda ECU where you have limited scope in modifying the parameters.
NOW. 60 k gets you a BRAND NEW STandalone Race Dynamics ECU where the tuning possibilities are ENDLESS.
I am waiting for the engine to crank. I will do a dyno and see where we stand.
Then we decide on the ECU. But you know where I am headed.

Something is wrong. Look at the RD graph posted by SNS_12. There cannot be such a big variation in numbers. Surely, something is off in my graph or theirs.

This car would be a monster. Any plans to turbo charge it later? |
After-market ECU is inevitable.
I am guessing, since the engines are similar, at least the engine will start. I am not sure I will use it for sustained periods on the 1.2 map, but the first start of a car after such a big heart transplant is always music to one's ears!

I was just thinking the other day that Brio has a power to weight of around 92ps/ton. The NA 1.5 should help it make around 125 ps/ton. That's near Baleno RS, Punto Abarth territory.
Now, think of what a 1.5 turbo will do to this small hatchback. Not sure if other mechanical parts can handle all that power though. |
A turbo is not in the offing. IF there is need for more BHP/NM, a Used Laura TSI will be next.

Also, with the Turbocharging, the clutch will wear out real quick.
I think CAI is as far as I would go after engine swap. |
CAI is also not a needed. The new Honda Z1 engine intake design looks as "CAI" as we need in this country. That's going in for sure.

Also, would love to see the car in action in person... if you are arranging for a viewing day in Mumbai for this car, do post it here

Rest assured, buddy. If there comes a day when my wife has to wear a helmet and climb into a rollcage to get into a car, it will be to run me over, KARZ style
It's her car and this is as far as we can go. It was very sweet of her to allow this, in the first place.

STRANGE!
Look at my Dyno figures! Somehow, yours are more believable.
Let's see how the final dyno pans out... (with the 1.5 engine)
Ok, guys, NEW ENGINE IS IN!!!
Today we crank her.
Ye olde L12B Brio engine out of the car, sulking in the corner
Updates in the evening...
