KDMax is back for HOUSTON next month for NEW TUNES or UPDATES to your current KDMax tune! The KDMAX 10.0 was released in early June. If you're not on it, you're not on the best 🤘🏻😎
================================
Note from the dyno operator:
Hey guys, Jacob here with DyNomad.
I'll post up some key notes about the Dyno.
First off, you cannot compare different vehicles, on different days, with different dynos, running in different gears. You will only go around in circles with someone trying to nit pick the results. It is pointless to compare a stock trucks power output using a Dynocom Dyno to a stock truck using a Dynojet. It is universally accepted that Dynojets are the highest reading dynos on the market. This is why so many tuning companies prefer them, because the average consumer is too naïve to understand that the peak power output a dyno shows is arbitrary.
What a dyno does is shows a delta. That is the only factor that matters. It wouldn't matter if this dyno showed that it made 100hp, the delta would still be the same percentage of change between the runs. Only focus on the gains over stock. If 10.0 makes 20 more hp than stock on this dyno, it will make 20 more hp than stock on a dynojet.
The 3rd gear vs 4th can skew results. The real reason why most people use 3rd in these trucks is because of wheel speed. In 4th we ran this truck to 140mph, clinching our bu******ks the whole time. At these speeds, driveshaft failure can occur from critical speed failure. Fortunately, we didn't have that problem, we just sent it for the science. When someone uses a non 1:1 ratio in the trans, or close to it, the torque values are usually misrepresented. Now, this can be corrected depending on the type of pickup that is used by the dyno operator. I would assume that the other guys used an optical pickup on the crank, or possibly an inductive pick up on the coil wire. IF they used that, the results are not so skewed, but if they used something called "snapshot" which relies on the synchronization of the wheel speed in 1:1 gear vs the roller speed, the results can be very skewed. Either way, 3rd gear is a torque multiplier. I guarantee if they ran in 4th, the results would not be the same.
People are going to get hung up on the overall peak power output and see that others show a higher number. There is unfortunately nothing that can be done about it. They did however use a lower correction factor that will read a little lower, which is surprising. They used SAE, we used STD. Its a subtle difference, but its there.
The big take away from this is the smoothness of the curve with the KD Max Tune. You can quite literally feel the difference. Look at the power difference under the curve between stock and 10.0. It is massive in some spots. You can clearly tell where the stock ecu is pulling timing around max torque. It is too conservative. The 10.0 keeps timing in there, maybe a slight adjustment after peak tq, and then ramps it back in. Stock wavers a bit. This is due to being on 87 octane. Others were on 91 octane. If we were to run this truck on 93, the difference would be even more substantial, but then again the stock tune would also increase in power.
Happy to answer anymore questions you guys may have. Remember, you are not selling these tunes for HP gains. You are selling drivability enhancements, the added hp and tq are just the icing on the cake.
