    2013 5.0 GT will not reset O2/Catalyst Emission Monitors

    Panic now, find out who tuned it and what all they did in the tune. NO amount of drive cycles will work if they disabled the monitors or didn't set the tune up correctly. The drive cycles can be done over a day, one them requires turning the car on when ECT is within 10*f of ambient...

    Hunting Idle, Backfire and jerking while driving my Edelbrock Stage 2

    Dipping at idle could be a few things, could be the decal gain, too much fuel maybe bogging it down until fuel trims correct for it or it could also be the idle airflow being set up incorrectly...

    Hunting Idle, Backfire and jerking while driving my Edelbrock Stage 2

    Your tune needs some massaging still, to get decel fueling you want to adjust the decel gain: Engine>Fuel>Transient>Deceleration Gain Exhaust popping during decel is from DFCO, make sure it's set up correctly, stock settings work well, but it could be popping extra loud because your decel...

    Sai Li fuel system any good?

    That's a fair install price for a shop. I would DIY it, but if you don't feel comfortable doing electrical and hose routing then having the shop do it is fine.

    VMP Ice tank Installed

    You have to get new hoses in order to re-route the set up. Hoses are cheap at most parts stores. You want to connect the tanks lower fitting to the pumps inlet and then set up the pumps outlet to go to the intercooler in the manifold. From the manifold the hose should be routed to your heat...

    IAT2 ranges 40-50* above ambient with HE/fans

    IIRC it's 0-5v and the temperature readings go from -40*f to 240*f...forgot which end is which though, not sure if -40* is 0v or 5v. HPtuners does have the ability to read both IAT1 and IAT2 with out issues, you just add the Air Intake Temp 2 channel and you are set.

    Recommended sparkplugs?

    Just put SP471's on a 10' with a trinity TVS on a 2.5" pulley and they are holding up just fine. TR6 are stock heat range, if you want colder go SP471 or TR7

    +1 Knock retard okay?

    On the copperhead ECMs(11+) positive knock retard means the ECM is pulling timing. The stock tune has the maximum set to 1* of retard, so if you are seeing +1* right now but the car is running fine and there is no audible knock, then chances are it could just be blower, engine, or exhaust...

    e85 tune issue

    Have him go to Engine>Fuel>Open and Closed Loop>Cranking Fuel>Fuel Cranking vs ECT> set the 90*f and up rows to 1 and the row below 90* to .98 That should prevent spraying too much fuel while cranking in the summer and spray just enough extra to turn over when it's cold. Cold starts with e85...

    CJ Manifild driveability

    CJ with mono blade and PMAS intake on mine drives like stock. Very good street manners. Parking lot speeds are also a breeze, there is no changing how you drive the car when you go CJ manifold, it should drive like stock, even when going 1-2mph over speed bumps.

    Whipple 2.9 power seems "inconsistent" and lackluster

    Your part throttle surging is prob from torque error due to TB data or Torque/inverse tables, not necessarily a mechanical failure. The heavier you mod the car, the more you need to dial in the Torque/Inverse tables. If you don't get them to zero torque error then you will get some throttle...

    Intercooler reservoir temperature

    Because it is a standalone system who's only job is to cool IAT's the temperature will always be relatively low compared to engine coolant. Engine coolant has to cool you engine down, since there is a thermostat it will usually always need to cool it down to 190*f, so the coolant will always be...

    2.9 Whipple tune

    The 58's are used in the gt500, there is plenty of support for them and their data is available from Ford. Are you also using their 132mm TB? Some tuner have problems with that TB, but the data for it is available, I had posted it in another thread. If you want to swap tuners hit up Rob...

    What happened to the On3 SINGLE turbo kit for Coyote's?

    They responded saying it's a track kit and you don't really need a sway bar at the track, if you want to keep the sway bar then get the twin kit...I may have paraphrased a bit, but that's pretty much what they said

    Whipple 2.9L front feed monoblade throttle body tuning issues?

    If throttle is hanging then he needs to set the TB data up. Yes those values will work for a 11-14 but your tuner will need to clip the resolution a bit since the 11-14 have lees columns than the 15+. Your tuner should know how to do this

    Whipple 2.9L front feed monoblade throttle body tuning issues?

    It's a pretty large TB compared to stock so you need to make sure you are using the right settings and have your torque/inverse tables populated correctly. To help you get started go a head and give these values to your tuner, he'll know what to do with them

    What happened to the On3 SINGLE turbo kit for Coyote's?

    Very nice, I wonder what about the kit causing issue with the front sway bar. Could it be the charge piping?

    E 85 Consequences?

    I wouldn't leave e85 sitting in the tank that long. There will likely be no ill effect on the fuel tank itself or your lines but e85 draws in moisture and begins to water down. You can try some fun stabilizer but I would still recommend against it

    Coyote timing, cam timing, tuning ect..

    Here is a good starting point for your OP spark map. I also included the modifiers to go with this map. The cells used in WOT are highlighted in blue so you could mess with them if you want. This is what I use as a base for 93 octane cars. It should command 26* of spark and then let KR add...
