it adds a little power, because e85 gets power just by being e85.

The wiring in the engine can get wet and it does get wet every time it’s driven in the rain. power washer could force water past the connector seals I’d use a hose.

on a natrually aspirated GT with a manual transmission getting a basic 93 tune this is highly unlikely to happen. If you are concerned, like genuinely concerned get some suspension mods

I've never done it, i plan to eventually but my intention is to try on a honda motor or a cheap engine. I'm under the assumption that the first one will likely not work right with that said, i've seen some jank engines run well. I saw a guy misplace all the cam buckets and it still ran...

The reality is that there's not really a way to know for sure. A dyno tune has the following advantages: You know how much power you're making you'll have a consistent load applied to the car during tune development A remote tune has the following advantages: You have access to a wider array...

add the 93, flash your non-e85 tune drive gently for like 15 minutes and you're good to go. That much e85 will do nothing signifigant, its going to be under 20% total tank concentration assuming 14mpg and actual e85. Which is low enough to where it doesn't matter.

do you have those exhaust clamps with the little piece of black tar in them?

yep you nailed it, its less power per unit volume but its stable at a much higher volume. So the total power in the cylinder is more. its also more all the time, i used stoich as an example but it holds true at power enrich too.

its linear though, so if its more at stoich its more at PE. More all the time.

no you didn't do it right. do this math for ethanol and gasoline: https://forum.hptuners.com/showthread.php?103455-WMI-on-a-NA-motor-reasonable-or-wasteful&p=735061&viewfull=1#post735061 gasoline = 18.4k btu/lb, gasoline stoich = 14.7:1 ethanol = 11.5k btu/lb, ethanol stoich = 9:1 at an...

No you’ll make more power at the same timing, there is more energy in the cylinder when running ethanol. Take a second and look up the energy per unit volume of the two fuels, then calculate the total energy at the two stoich afrs.

If you're gonna be snarky you need to be correct. ethanol makes more power even at the same timing, its always a good choice.

Ethanol makes more power even at a fixed timing when compared to gasoline. If you disabled timing advance on your car, filled with 91 and did a dyno run and then filled with enough ethanol to make e30 and did another dyno run you would make more power on ethanol. Ethanol isn't just an octane...

Ford being unable to communicate with the car indicates a larger failure than a tune. Ford can reflash a car that's been tuned. I'd definitely want the dealer who sold the car to me to make this right.

It’s very simple, that’s about a 12% increase, so all of your gears will require 12% more engine speed for a given wheel speed. As an example: if 3rd gear used to be 30mph at 2k rpm then after the change it will be 2250 rpm at 30 mph.

an M2 is a bargain to maintain compared to that 911 you're considering. My coworker had one with the intention of doing headers and an exhaust. Those two parts were $7k each before labor. Ended up selling the car for a ZL1 but for unrelated reasons. The truth of the matter is however, if...

no if its disabled there wont be codes, but your issue is likely that your H-pipe is too long. Check the clearance from the connector to the pinch welds. If its tight , cut an inch off the h-pipe

All tuning software will allow you disable this with one switch.

ITT: “NEW CAR BAD OLD CAR GOOD”

If the car is running with an error in its o2 sensor feedback, it can be tuned out without realizing. You can adjust WOT lambda and the MAF curve to "fix" what it actually an error elsewhere. I have a 21 year old BMW sedan that uses the downstream O2 sensors for fueling adjustments exactly...
