OP cam angles changed? Pe?

Ford. Or get a used long block and install or even new long /short block. I wouldn't do anything but the bare necessities if replacing one piston. Not worth upgrading anything else. Stock will hold assuming tune and fuel is adequate for boost and that bore is undamaged. If your going to...

Cheapest is single piston and clean up hone. Block has to come out regardless. Would pass on used. Fords not that expensive usually Any logs or copy of the tune?

What's your take on why whipple/ roush/frpp and even the gt500 and ford gt supercar all run this at 90% pedal? Mpg? Always assumed because of the bdr/mbt lambda scaler that they did their homework and pulled enough timing out. Another work around for load based lambda is the cold fuel table on...

echoing what has already been said. Roush setup on gen2. stock IC using the dinky bosch 5gpm and 3/4" thick HE. spacers and heatshield products adhesive backed intake manifold blanket like @stang17 did. 20-30* above ambient/iat. Dropped to 20* under wot or heavy throttle. Never heat...

I reached out to them as well. I suspect there are some misunderstandings on fuel system variances across the coyote years/models and different markets that go unnoticed until tried. Same response. Their system starts at a high pressure and decreases pressure as flow increases by design...

Having a fall back tune makes learning realistic in my book. Even more so if you kept an ej alive. They hate ringlands more than certain tunemaker coyotes! Big reason why it's such a benefit for boosted guys when roush and whipple cals are supported in our tuning suites. Can learn from and...

Add fuel pump duty cycle to your chart. 49% is 100% dc, 6.5% is 0%dc. 75% is off command. What's the low frp kpa at idle?

What's your duty cycle at wot? How much room remaining?

Anyone had torsion wear right rear faster than left?

The 350 arms look the same as pp, maybe not what you want then. I'd take busted arm over torn mount in the cradle. Audi does this but usually uses alum arms. I bet you'll be fine if they all made it through fords r&d. Although the rear shock mounts did too...

The 350 arms have a different height on the ball joint if you wanted another option to look at. iirc they were setup for a 3/4 drop compared to gt and adjusted the arms to match. That said I've been on the pp arms and lowered an inch for few years with out issue.

Are you lowered k4?

ideally native or built in pump control can be fine tuned to be a head vs always reacting assuming pumps got enough steam left. worth buying some credits if coding can be ported for gen2 guys imho! only chance of knowing whats coming is getting it internally controlled.

might ask wengard to adjust the feedforward table and pid. pumps taking a second to respond to the demand. https://forum.hptuners.com/showthread.php?96010-Gen3-Coyote-Boost-a-Pump-lift-pump-tuning I think you are fine fuel wise. it is able to recover and at 86% DC at redline.

For fuel pump control we should be in luck on the gen2. Its already pwm controlled but limited to hi/lo/off by the tune. The gt350 uses the 1791 but employs variable pump control and fuel pressure sensor feedback. Same/similar as gen3 and gt500. Tables are different on gen2 though. Would need...

Good to know on the abs module. Thank you for sharing. Even better if there are tables already available. Guessing there are pids we can log too? Belive mainly Its the wheel slip/ slip ratio allowed that doesn't seem to be adjustable or I haven't got to in the pcmtec files yet. From there its...

That's promising!

@Rolls access to the abs module possible to adjust traction control?

@engineermike Now you're just bragging... :wink: I'm itching to play. How far can we take "custom"? Native pwm fuel control with external sensor added? I've got a few things beyond flex I'm more interested in.
