Thank you for asking this as I was unaware as well. Could someone point us in a direction of the map that shows different fuel trims per cylinder? Or a thread discussing this? I was unaware oems were doing this.

I'm running a Motec ecu on my GT86 with 4 lambda's (one per header) and its very clear just how bad the intake and exhaust paths are and the amount of difference required. Its not a constant offset either, amounts cross over. If you measure each intake runner and exhaust runner length they all have a different total overall tuned length so it's not surprising at all. When will pricing and completion date be confirmed on this? |

Is there any way you can publish the data on the cylinders and what you found? OT but Tim are you in the UK? I guess if you're running a Motec then you've a little more than a standard car.

Car is not standard no. It has an NA build now and i'm about to do a turbo build. Dead keen to find a proper intake manifold though as I want to run loads of boost and stumbled across this thread. Some awesome products appearing now for this car at last |

I was more interested in what you had found on the stock setup, rather than how you improved on it

Didn't do anything with the stock setup unfortunately. Took the car to the racetrack straight from the showroom to see what it was like then brought it back and put a Motec on it.

All this talk about sucking and blowing, with all these sexy pictures makes me wonder why this hasn't been labeled NSFW.

I was aware of the unequal length of the exhaust manifold, where do the variances in the tuned length of the intake runners come from? |

I have no doubt that you can pick up significant power by optimizing cylinders. There is a great video on youtube detailing how NASCAR does this and they pick up multiple percentages of power. I just didn't think OEMs were to that point yet. |
