Sounds like a good day was had by all and great results to boot.

It's good when you can make a change in a tune and see the results on the dyno. Unfortunately unless you have access to the equipment it's not something easy to do.

Actually we found power wise our seat of pants tuning was spot on and either way of what we had there already made the power worse.

However mid and cruise areas were able to be dialed in much better. Another thing we found was leaning it out up to gained a surprising amount of power. Above 13:1 it seemed to like a lot.

Some mid load low rpm areas liked upward of 30º timing which was a big surprise for me. Like 1200rpm at 85kpa and the corresponding rpm at lighter loads liked a lot less timing. Very much the opposite to the norm.

Must be those bananas at work

Can you post up what engine mods it has and a copy of the tune?

Those bananas do do interesting things with the extremely long runners.

How'd the 100kpa range go on the dyno compared to logs on the road? VE pretty right?

I don't think its the length, rather the interference from the weird shared plenum they have.

little bit lean. Was spot on in the past so I guess the change in ambient temps might be at play as the injectors aren't calibrated in the tune and neither has the inverse temp tables. Runs manga ones iirc. The manifold gets some serious heat soak too due to the bigger cam.

was 5% out in the VE up top but alright everywhere else. Tune is about 90% right, more time is needed really but it goes great which is the main thing.

Magna blue tops? HSV ran them. I've got them in my car. I got the settings for them from the HSV stroker tune as they ran them from factory. Seems to work well for me and a mates car that runs them as well. If it's stroked run injector rate of 0.13 if it's not run 0.12. Ive done that a few times and VE ends up in high 90's on a worked motor.

Mind posting up the injector data? dead times, adders etc.. those are the injectors.

No problem check back tomorrow night I'll get them up. On my phone having a few beer's.
