![]() OBDII adapter and USB cable are included in the box.The color display and buttons are quite ok to serve the purpose well.Turning on the tuner and installing are as comfortable as falling off a log.Another Wi-fi enabled tuner from SCT lets you download the updates effortlessly without relying on connecting to the computer.The gauges have a customizable user interface.Now, let’s move on to read the review of the tuners. The installation process, display quality, mounting facility, ease of navigation, etc.Its capability to increase power, performance, fuel efficiency, etc.First off, the obvious: if it fits for Mustang or not.In this article, I’m going to review the 10 best Mustang tuners of various price ranges that fit different Mustang years and models.īefore I dive into the review part, let me tell you about the criteria I considered to put a particular tuner on my list – You can do it effortlessly using some of the top tuners for Mustang out there, both handheld and chip. I’m sure you don’t want to miss that chance to take the potency of your beast at its highest level. There is always room to increase the power and performance of your vehicle. It doesn’t even matter how powerful it comes from the factory. It's not exactly what you are looking for but it's feasible with HPTuners.It doesn’t matter whether you drive the old Mustang model or the latest one. EcoBoost can have it enabled and work properly in a 85% solution at least in my situation.Īs for your question about spark advance, there are separate tables for flex fuel like the cold start table (where you will need to add more fuel during a cold start for E85) as well as the octane adjust table, etc. The 2.7 EcoBoost stock HPFP is large enough capacity that it will handle the stock turbos maxed out with full E85 (HPFP pressure looks good, injector duty cycle maxes around 30%-40%)įor the TL DR - The Coyote's seem to respond very well to enabling Flex Fuel. I suspect there is something else going on with my car, as there is a known issue with the fuel level input fluctuating on this particular platform so I have seen it switch from Fault Exit to Refueling just idling (and I didn't fill up on fuel). No such luck on the 2.7 - and the problem is that until it matures, the system disables the long term fuel trim learning as well as the purge valve operation. On my actual FFV Ford (N/A 3.5 in the Explorer) it will mature within about 15 minutes of normal driving. However the problem I am encountering is the system is in perpetual active learning mode. For instance if I fill the entire tank with E85, the stoich will drop to 9.8 and my STFT's will be very low. When I enable flex fuel, the stoich WILL adjust to accommodate. I am not sure how hard it is to enable on the Mustang EcoBoost, but I have been testing it on my 2.7 EcoBoost in the Fusion. I've seen lots of aftermarket/modified alcohol sensor systems that use the GM sensor in-line in the fuel system. The other system uses an alcohol system inline with the fuel system which GM used for awhile but has switched to the virtual/inferred system on the newer models. Yes there is latency but it seems to work. Ford always seemed to use a virtual/inferred system where it relies on wideband O2 sensors to make adjustments. Ford and GM flex fuel systems have varied from one another over the years but have become similar. In addition, adding ethanol means we are gonna run out of injectors pretty quick, so there comes an issue of additional fueling.ĭo you add a new hofp or go to port injection?Ĭlick to expand.The Coyote is flex fuel in the F-150s (enabled by default) but it seems the Mustang GT owners can turn it on very easily with HP Tuners.Ī little clarification of Flex Fuel systems being used. IE I would give up cruise control if I had to. The Coyote doesnt have a provision to run that signal to the ecu unless you go to a standalone ecu, but the Ecoboost ‘should have’ a way to run that input even if its in place of something thats already there. The flex fuel tune Im talking about and the only kind that should be allowed to call a flex tune is with an actual ethanol analyzer like the Continental one that gives you a signal that the ecu reads and adjusts fuel AND TIMING according to the actual amount of ethanol in the system. These ‘fake’ flex tunes use an O2 sensor to add or remove fuel!Ĭan you even imagine that? Do you know how much latency there is? A lot! Very different from an actual limited slip. Kind of like the oem’s marketing electronically limited differentials when all they do is apply brakes to the wheel thats spinning. They call them that because it faintly resembles a flex tune but its not. ![]()
