Dyno Tuning

Panic Motorsports’ rear-wheel-drive clients have the opportunity to benefit from dyno tuning on a Land & Sea DYNOmite chassis dynamometer system with tuning programs from Hydra EMS, AEM, Megasquirt, ECU Tek, and EFI Live – HP Tuners.  What does this mean, exactly?  We have the ability to complete “high speed testing and road-load simulation without leaving the garage.”

Quite simply, our dyno set up is better than most because of its load bearing capacity.

This allows us to build a full Volumetric Efficienty (VE) table, not just the wide open throttle (WOT) pulls like on a weighted drum dyno.  We’ve selected (below) what would be just the WOT part of a dyno pull, so you can see the very limited selection that goes into doing a power pull on the dyno.  The same also goes for the timing table: It’s the same small section for a WOT dyno pull.

What our dyno lets us do is get all the un-touched places of the VE and timing tables for logging drivabilty changes.  Because, let’s face it, anyone can tune WOT. The real master of the craft is in all the small adjustments it takes to make a modified car drive like it’s stock.  To have the ability to get in, turn the key, and drive your hot rod to work like it’s the family sedan is why all the new electronics rock.

So when people want to know why dyno time costs $150/hour and averages $500+ for a tune, it’s because there is time spent on the dyno not nessusarly making power but optimising the calibration for seamless drivabilty.  This is commonly referred to as steady state tuning.  As the name implies, we’re holding different loads and RPM at a steady state and load with the dyno to log and make adjustments to the VE table based on the airflow of the engine.  With out our eddicurrent absorber Dyno, we couldn’t do this.  The absorber makes it so I can set the dyno at 3500RPM and no matter what throttle input we have on the engine, it will hold that RPM.

Even with the larger HP cars like Josh’s LS1 swapped RX7, we can work up in 50RPM, 250, or even 500 increments to work our way up, down, and across the VE table to fill it all in.  We have a turbo car here this week with which we’ll be doing just that, to make it driveable for both the track and the daily commute.

This is what a data log looks like for a visual.

So when you schedule a Dyno Tune with Panic Motorsports, which you can do so by emailing Josh Smith at josh@panicmotorsports.com, you get a complete tune suitable for your racecar, street car, or weekend warrior project car.

Please visit our Tuning Service page for more information and be sure to reference our pre-tune checklist prior to scheduling your tune. If your vehicle is in need of additional work prior to the tuning appointment, please let us know so we can schedule things appropriately.

Any questions? Don’t hesitate to contact us! We look forward to working with you! 🙂
