ARCTIC CAT 700EFI DYNO RESULTS

Since the dyno graph for an automatic reads backwards (or right to left) I will break down the gains from low speed to high speed.
These gains were with the HMF Slip On Muffler and the HMF Optimizer EFI Recalibration Tuner.
With the HMF Slip On, you MUST recalibrate the Air Fuel Ratio using the HMF OPTIMIZER to prevent extremely high internal exhaust temperatures from causing catastrophic failures.
The EFI system on this machine DOES NOT make adjustments to the AFR, it DOES NOT have an O2 sensor so YOU have to make AFR adjustments to the EFI system with the HMF OPTIMIZER EFI TUNER.
The OPTIMIZER EFI TUNER is pre programmed to OUR pipe, no guessing. Unlpug the stock connector to the injector, plug the HMF OPTIMIZER in line and make a ground connection and you are DONE !! go ride.
NOTE:
IF you live at altitude or in extremely hot or cold climates some minor tuning may ne needed as the OPTIMIZER is set for basic sea level 65~75 degrees.
The "load sensing" option built into the OPTIMIZER WILL adjust to a degree but not to extremes. There is PLENTY of adjustment (+/-) built into the OPTIMIZER so whatever you do, wherever you are there is enough to play with.


BLUE = ALL STOCK.
RED = HMF SLIP ON/W OPTIMIZER.
