Tuning Query - upgraded parts - Stock engine

Hey,
I've just acquired 550cc RX7 injectors and a Z32 MAF.
My car already has a New Walbro fuel pump.

Have also installed a 14Point7 wideband O2 sensor.
The company are offering a new product :

will it help tune the car to run on the upgrades ?
If so is it the best option ?

Thanks

Sounds a bit gimmicky to me tbh
Some piggybacks have come a long way lately to rival standalone ecus but they have knock and timing control, basically the stock ecu just controls the sensors such as idle control etc but piggyback takes over the timing and air / fuel ratios.
The link you put up just seems to be a glorified air /fuel controller such as safc and other similar devices which just fool the afm so personally I wouldn't waste my money as you need to take in knock values with timing adjustments throughout the load and rpm range

But having said that I'm no tuner, just what I've learnt and picked up from other more knowledgable people.

Thanks, so would you rather go for a daughter board option like :

they seem like a popular choice. similar to Moates
