Nevertheless, the datalog used to calculate the results for the Helix is suspect because each pull, especially the ones in 2nd & 3rd gear, did not reach at or near redline like all the other FMIC's and their datalogs. The RPMs with the Helix reached only up to 6300 at most in the first two pulls and only up to 5600 in the third. In comparison with the other competing datalogs, the Helix FMIC was not subject to same high RPM conditions/stress as the others. Therefore, the Helix has an unfair advantage in IAT results. New datalogs must be made.

According to the calculator, the Spearco/Code3 seems to have performed the worst, but it's also the only one that used a datalog where the engine reached at or near redline in all 3 consecutive gears.
