You're running a MOTEC like John, is that correct?
So, can you plug an AFR target into it and go from there?
Yeah, we are both on M150s with some slight variances in firmware. The Syvecs I was on before worked similar as far as AFR target and go from there.
Really the AFR side of tuning is easy and straight forward compared to everything else, engines are pretty tolerant of variances in AFR- way more robust there than many people think and not a ton of power to be gained across a fairly wide range of AFR. Just set your AFR targets and go through calibrating the fuel table until it is on the money.
Ignition timing is another story and abnormal combustion can kill an engine quick so thats where I like to go cell by cell, adding a degree at a time until I hit my torque target or torque stops making substantial increases with each degree or 2 (on the Mainline you can monitor wheel torque live and add timing and watch the measured torque go up or down with each change while holding rpm and load steady), or I pick up signs of knock on the ecu or on the headset (I use an audio knock detection tool in addition to the ECU knock sensors just in case).
That one is a Mainline Pro Hub actually but I think the Dynapacks are similar. Loved using it. So much easier than worrying about strapping the car down onto rollers and everything that comes with that and the way the dyno could manage load and limit rpm made tuning in each operating cell a breeze. Unfortunately, he sold it and moved out of state.
CC is looking at getting a Mainline Pro Hub dyno for his shop if he can get around the noise aspect of it. Would be killer for him to have that on site.

That would be amazing. Such a versatile tool for calibration work.
Ohlins finally installed! Got the tarret rear links too. Only did a short drive last night, but the main thing I noticed is how much less squirrelly the rear is under WOT. Even in a straight line the car feels faster which goes against my intuition with a suspension upgrade, but makes sense. I’m at 10-10 now, and have the extenders, so will be playing with it later! I think we landed in 25mm drop and it’s peerfect.
After my Ohlins install I noticed much more stability when blasting out of corners. And a weird sensation of being able to add more steering when cornering hard. Huge improvement.
