Dyno TUNING day (Springfield, VA) July 12th
 

Newbsauce and myself are planning a trip to a dyno for a bit of tuning. I would like to see if an other locals wanted to make it out and get in on a good rate.

It'll be at:

AA Motorsports
8538-E Terminal Rd
Lorton, VA 22079
703-339-5566

On a Dynojet 424x AWD dyno. Equipped with a 224xlc eddy current brake for steady state tuning.

The rates are great:
3 ppl.. 90/person
5 ppl.. 80/person

this is for an hour of tuning with an operator to run the dyno.

If you just want power pulls, it would be less for sure.

Brad and I are commited to go, but we figured we'd ask if anyone else wanted to hit it up.

thanks, enjoy, peace my homeys.

I'm very interested! I have a crappy street tune running now...

good! do it!

Thats a great rate. I need to find a place around here to give me prices like that.

we are lucky in this area. steady state dynos all over the place. All these shops love to do dyno days. I've seen some for $35 for three pulls, $40 with o2 log.

WARNING: Noob alert!

Do you guys know how to tune the hydra? I'm guessing I just let it sit for a few seconds at each of the cells as the dyno adjusts the load? I have no clue how to adjust my timing too... I'm a little afraid of that. I'm guessing that it'll take an hour to get my fuel map down though.

What pre-dyno prep work should I do? Oil change?

convince y8s to come out and help. He was invited, but doesnt need to tune on a dyno at this time.

When I went last with y8s, he threw on autotune, and then walked through each cell few a few seconds each to get a good reading. Took almost an hour there, having to stop and idle when doing boost as the coolant temps inevitably start to rise. He seems to be pretty happy in the tune right there.

Once he did his fuel, he start doing some power pulls and playing with spark at certain rpms. then a little vvt fiddling.

I'm not doing any maintainence before the dyno, just making sure the oil is full. I'll pretty much only be playing in boost and with spark (I honestly dont think I can dial my fuel in any better), however, I'm only familiar with the MS, and Y8s' hydra confused me with all it's features and GUI :) What I plan on doing is seeing what spark angle I start to ping, how retarding/advancing down-low effects spools, what spark advance gives the most torque throughout and what AFR gives the most torque.

I need to have a head count by monday..so let me know.

God damn you, if this was later in the month I'd join as I'll be visiting a friend in Arlington.

you can come join us doing other stupid things, like breaking stuff, or making fools of ourselves on the 1/4, things of that nature.

Well, I do have those qualities in spades, maybe I'll take you up on that offer.

Do they have a mic and headphones we can use to listen for knock? I don't know if that's a BS way of tuning but I've read that is the best way to check for knock. I don't know if I should trust the knock readout in my Hydra off the factory sensor.

no and you should be able to, the hydra's knock sensing abilities with the stock sensor is pretty good. It's hard not to hear on the dyno with someone standing at the motor.

i was gonna plan on coming anyway. not to dyno, just to get in the way.

and I wont tune your hydra. I will show you how to tune your hydra. how's that? I've learned a little since last time. for one, with the hydra's autotune it's pointless to waste time by hitting every cell. you can set it to "learn fast" and do a few pulls at various loads. much easier. and spark tuning is probably easier to do by doing a baseline and adding/subtracting 2-4 degrees to see changes in the power curve. it's impractical and hard on the motor to hold a car at 6800 rpm and 15 psi for very long without airflow. water temp goes up like nuts. just learn to compare graphs.

johndoe: it's only a 5 hour drive man.

I'm in if there's space.

So far I got:
1> Me
2> Scott Diddly
3> Pschmiz
4> Fae... (did not see a def yes/no?)
and Hobo y8s from DC (observer/knock detector)
and Lars (observer/knucklehead)

I am leaving tomorrow for WV, but I will confirm with the shop Monday, so thats the deadline. If Fae is in we are closed. :)

if you guy are committed we'll lock it in on Monday and let you know. I don't really wanna have anymore as it will take too long and I have a short attention span.

Brad try to get the $80 rate :)

I'm fairly convinced I can get us something in the middle of the 3/5 range.. so I will push for 85.

hey, I'd love to come. Maybe if I get the 550s in, retune (wait, haven't tuned much at all yet) and then get the turbo in this weekend and then do some more tuning and my clutch doesn't blow up I'll think about it. Then again I've never tuned a car before or installed a turbo so I'm probably gonna take it slow. But I would like to.

I'll hopefully be there for moral support as well.
