Need opinions on tuning options

Motion Lab · 06-27-2013, 10:56 AM

Option 1 seems like the better deal, but I always look at experience not price when it comes to tuning. Bad tuning, especially VVEL which can cause a catastrophic failure if pushed too far in one direction, can cause major issues short term and long term on your Z.

Also when you have a loaded dyno you can simulate driving down the road. I dont understand why you say you can only tune open loop fuel tables on the dyno?

Thanks,

simply because you cannot simulate a true drive cycle unless you have a programmable rolling road type dyno.

This.

You can't simulate a true drive cycle without a rolling road in a wind tunnel. Period.

(Professional, big budget) Race teams do exactly this. The rest of us road/track tune.

I was just thinking about this now that a vendor has come up with VVEL tuning (and I heard rumor that Uprev has it in the works, too). Seems to me that messing with VVEL has the potential for 'issues'. You'd better have a damned good tuner if you want to start messing with it.

We do it to every Z on our dyno, really helps fatten up the power band

My second post in this thread seems to puny and insignificant now.
I think you guys even scared the OP away.
