Good experience with dyno shop ( Granite State Dyno )

[jeffw]

With DSG out of the picture, I've been hunting for a new shop. Haydn Taylor suggested I talk to Alex at Granite State Dyno.

I was in yesterday and met Alex. He's very knowledgeable, with experience tuning cars for the track. He's careful and analytical, and he was able to smooth out a few rough spots in the 3k-4k RPM range.

As is always the case, I was looking for more HP and TQ on the last run compared to the first (baseline) run, and that was true.

i have an appointment set up with alex for 4/20. lets see how he does with turbo cars. i hate changing tuners, im a bag of nerves until its done and running well.

What kind of dyno? Are they able to do steady-state tuning like DSG was with the Dyno Dynamics, or just pulls?

There is alot of information on their website, including the phone number.

It's a Dynojet.

Hey Jeff,

If you don't mind me asking, what kind of ecu are you using?

[jeffw]

I've got a megasquirt PNP.

Very helpful, I never would have guessed that... Especially where it sometimes takes me the better part of a week to make time for personal calls about getting my car tuned while I'm at work And, I did look at the website - it doesn't have enough info to answer the question. But, regardless - I sent an email and haven't heard back yet... I'll post the response when I get it.

Thanks Jeff. Do you know if it's the Steady State version (Eddy Current, I think)? Any issues with familiarity with the Megasquirt?

Thanks for the heads-up and the recommendation, Jeff. To get a NASA reclassification for their new TT3 class (Super C in COM parlance ), I need a dyno pull on a 224 done, and GSD would be very convenient to me.

No idea if it's steady state. He did spend a little time at 'cruise' but mostly did pulls. Some pulls were logged thru all the gears, some just in 4th.

Alex seemed to know the MS quite well. He used both TunerStudio and MegaLog Viewer in the process. For some reason TunerStudio on his laptop couldn't connect to my ECU (he had recently updated TunerStudio), but the old tuner software could connect. He ended up using my laptop to do the tune since it was already working.

Thanks Jeff. I'm in the market for an ECU and knowing a local dyno can tune it is good news.

[jeffw]

The MS is quite good for the miata. It's good value for the money.

It's also got good support in terms of tuning tools. It also has good support from other company's tools. For example, I have a connection from the ECU to my Racepak data system that logs everything the ECU is seeing along with everything the data system is seeing.

Jeff: What SCCA class does your car fall into legally (with MS, coilovers and everything else you've done to it)?

The shop has a Dynojet 224x (2WD) and a 424x (AWD). Neither are capable of steady state or load testing, need the xLC (load-cell) version for that. But as always it is more about the tuner than the equipment.

You're true that a competent tuner matters, but so does having the right tool for the job.

The good thing with Dynojets is their repeatability, but the problem with inertial dynos in general is that they can sweep (accelerate) so quickly on sweep hp tests that it can be hard to properly tune a fuel or ignition map. You can get acceleration maps triggering, affecting the reading. Even if that's not an issue, it's much harder (if not impossible) to hit all the load cells that you can with a steady-state dyno. Even when you can hit them - you can't hold there and adjust fuel/timing for best power cell by cell. For pulls, or power readings for classing - the dynojet may be better. For tuning though, a steady-state dyno is the better tool.

Still have an email out to them, and if I haven't heard back I should have a chance to call them later this week myself... (And regardless of the dyno, I still might end up using them too)
