Hi all, 

 

I was wondering if anyone would be willing to share their SPi fuel map. 

 

I'm on a SC 45mm SPI throttle body kit / D400 ECU. It starts and runs fine, I suspect a little rich (drinks 25mpg driven sensibly!) and has some backfire when my foot's off the throttle. 

 

I realised that at low TPS / high RPM the fueling may be too rich, but thought it'd be helpful to have a reference point. 

 

And yes, I know specific engines are calibrated to the different engine builds, climate etc. And I also have a reference point from SC's standard base maps on their website. Just wanted another from someone who has tuned and are hopefully happy with how its running. 

 

Best,

Kopi

What is your wideband saying?

Where are you based

[kopi]

I'm based in Singapore and its currently running on a stock SPI lambda which I understand to be narrowband.

It is. If you're running an aftermarket ecu, you should really be using a wide band and controller.
