But... I also have none of dem e85 problems...

... going by Birds' comment, he's saving not a great deal by being on 98, for less performance.

It used to be CHEAPER than running 98, it's now marginally more expensive.

Is more inconvienient though.

Just sayin, if you have the means to alter and do your cold start yourself, E85 is a non issue to get going in the morning.

Car started on second crank this morning, leading me to believe that unless the 98 mix isn't pure enough (doubt it, given 59L/63L), I may have an injector issue be it a leak or blockage. If I recall correctly my car always did this since I put the injectors in...and E85 tune obviously exacerbates the issue into a 5-6 crank start up on cold mornings.

In the scheme of things for you it's probably not a big deal, especially as you don't daily it, but for everyone else who don't have tow trucks camping outside our house like velociraptors, we expect to get going quickly each morning

And not to wear out our starter motors

A few minutes, yeah, that's annoying, but 6 cranks...

We are speaking 6 cranks right? Not 6 full on attempts to start it and the car failing to start/stalling before being able to successfully leave the driveway, yeah?

6 cranks (which is literally 2 seconds) is quite different to 5 full minutes of general swearing about how shit E85 is in winter.

6 turns of the key, cranking for about 3-4 seconds each time. Then you have to keeps the revs up nice n high everytime you slip the clutch for the first couple of minutes of driving

Your tune be shitty mate. :P

Thing is my bros and Jasons did the same thing cold starting tuned by a probably the most popular tuner..

I think it's normal, how's yours Simon?

Fox RNB friday again woot

The tuner is likely guessing the cold start mixtures unless it's a 2 degree morning when he tunes it from cold. As Greg said, the best cold start mapping is achieved by yourself fiddling on cold mornings, once you get it right it should start just fine.

This is a bad tune (or at least worse than mine).

To be fair, it can be tricky to get right.

But it can be made to be right.

My car (of all cars!) will crank over 3-4 times and start at any temp on E85, through one attempt of turning the key and I'm on my way, ready for my car to break something else.

It can be done, hence my confusion on the subject. 6 turns of the key is quite different to 6 turns of the starter motor to get up and going on the way to work.

This'd be a dream for me atm...

Mine rolled into the tuner with 1/4 tank of ~P100, drained with the fuel pump and topped off with E85... so the tune was done in warm weather with ~10% Petrol

Started up 2nd or 3rd rotation of the engine on the first crank in the following weeks (barely driven), but after the next track day (and multiple tanks of E85 bringing it back to a Pure mixture) it turned to crap.

4-5 Cranks of ~5 seconds each... not even giving a cough until the 3rd crank, and once it was running I could even touch the throttle until the water temp got up to 40/50c, anything more than 10% throttle would cause the engine to choke out and revs to drop to stalling danger zone.

Once running and warm, it was perfect for the rest of the day... But trying to cold start an E85 car with an incomplete cold start tune, before 6am, with a Ti straight through exhaust... It's not my idea of a fun time. I'm sure it'll be perfect after dropping it back into the tuner for a few days to get a touch up now that the variables (fuel and temp) are correct...

But Birds is right, E85 doesn't have the appeal it used to for street cars, mainly due to the price coming back up so the savings no longer counter the inconvenience and increased usage (reducing range)

Ric I normally dig the styles but that "nanna's just made us marmalade on toast" shirt is ruining it for me...the colour contrast works but dat pattern damn

It's a bit more poppin irl :(

Truthfully, all tuning (other than power tuning) takes a lot of time, a lot of logging, a lot of driving around, cruising, half throttle, DIY'ing the cold start and making little corrections here and there.

And then on most ECU's, get ready for corrections for 98, and just a lot of little tweaks here and there. Having someone have it overnight for just a flex tune is just near impossible to get fully right, so I'm not surprised people have e85 cold start issues or boggy spots on the fuel that they don't use 95% of the time - The time it takes to get it spot on is WAY more than what you spend going WOT on the dyno, but people aren't going to spend $3000 on labor to get a tune 100% spot on..... until you change... anything.

Still appeals to me, as it has saved my new race engine a couple of times. (reg hose popped off and ran 16:1 at 32 psi at Sandown.) A petrol tune would have melted the pistons within a lap.

I don't know enough about how E85 runs cooler than 98, but the issue with mine is if I want more power (more boost) I need an intercooler as any more boost than I'm currently running starts to heat soak, even in summer + a few good runs you can feel the power drop off a bit. Would E85 eliminate heat soaking issues? or does the air need to be cooled before going in..? Would basically save buying an intercooler, and I could pump like another 5psi in with a new pulley + injectors only. (cos yeah, intercoolers are like ~5k for a decent one)

I guessing this isn't how it works though as I'm sure people on the ford forums would be all over it

    • Throwing my spoon to the soup here a bit.  When I installed a 044 back in 2012, along with the direct power mod, the car became very difficult to start. To a point I burned one starter motor as I was late for work and tried to get the thing going. With some tuning and careful use of gas pedal when cranking it became bearable. Trying to make this short as possible, but the 044 died after 2-3 years, after which I went with an AEM 320lph pump, which also died after about 4 years to my dismay. After that I went with a Nismo pump, and while trying diagnose an emissions problem, I noticed for the first time that my fuel pressure was 5bar/72psi on idle, and that removing the vacuum line did nothing. After monitoring the situation, and removing the direct power feed and going back to FPCM in attempts to remedy it, I noticed there was fuel in the pressure regulator vac line. Kept the FPCM, installed AEM external regu and the car became sooo much better in every way, including starting. And I had driven it like it was for 11 years.. Anyway, I agree these are likely two different problems, and the FP problem you just haven't noticed before. I do not know much about haltecs, but what first came to mind was the CAS, which probably is not there any more. So how is the wiring from haltec to gauge cluster? How is the battery voltage and alternator?
    • Your car was auto before? You have different diff ratio (auto vs manual i think? or n/a and turbo?)
    • +1 for getting a screen off alibaba, CarPlay/Android Auto is vastly better than whatever navigation cars had 10 years ago. I got an Android screen for my 2015 BMW, huge difference. Fully compatible with factory stuff including iDrive controls.
