This one will give you an idea of what I'm talking about re. shifting up to 5th, holding it for a sec and then gunning it.

Definitely all one gear. I think I smell smoke... Coming from your ears Cwis?

I didn't understand the whole 1:1 ratio thing before though heh.

I just havent ever done one so I didnt know the specifics, I just knew the purpose/reason behind it.

You're a trip.

simma!

Wow, I'm surprised to see how the TQ plummets after 5k rpm.

vipor · 04-09-2010, 11:59 AM

yeah most TQ "curves" on the VQ's are pretty flat....

XwChriswX · 04-09-2010, 12:00 PM

What can we do to help bring it back to vertical?

You don't want it vertical, lol. You want it horizontal. (Maybe that's what you meant.) But seriously, I'm wondering if it has something to do with the AT. I mean, considering how flat mine looks (which is 6MT).

You don't want it going up? I thought more = better? Or is that just for HP?

I had the same question and the tuner came back to me today and pointed out that the scales are different between TQ and HP - duh
He sent me a dynojet format and it looks like what you would expect

semtex · 04-09-2010, 12:12 PM

You want it to go up as early as possible to its peak level, then stay there. What that translates into is a car that pulls early and continues to pull all the way to redline. If you had a curve that went upwards, it would mean that the car only pulls as the revs get high (think Honda VTEC). And I don't think you'd want that with this car as people already complain about how there's a lack of grunt below 3k rpm.

OH ok. I thought you wanted it to 'keep' pulling, so going up on the scale. See like I said, I'm pretty low on knowlege of the science of dynos lol I just know higher numbers = good (minus practicality)
