What’ll be the problem? I’m not running full E85 plus I daily mine. If its not just sitting for extended period ls of time injectors will be fine otherwise I’d get stainless steel body injectors. Plugs? This isn’t my first rodeo running E85. Had it on my 04 STI fully built motor Full Race Borg Warner 8374 EFR twinscroll 612 awhp 597 ft lbs and was on full E85.
Your sti isn’t the same as the type r lol. Fueling for the type R runs out on pump gas when tuned.

As long as Hondata’s fuel pump duty cycle management is enabled it’s not maxing out the fuel pump at 40%. That statement about the pump taking a huge nose dive is with the stock tune? I’m sure Hondata’s ots map has addressed that because I personally know who does all the ots maps for Hondata. There was just another revision to the Flex Fuel calibration I updated. They’re constantly doing R&D on their Flex Fuel calibrations on the dyno and on the track.

Go and look at your datalogs

the whole "runs fine" term gets thrown around very loosely.

have you looked at datalogs? the fuel pump duty limit thing is a gimmick and you will still hit 100%. Then it will start limiting the fuel pump and makes your air charge all choppy. It is imo not smart to rely on that and best to tune your aircharge to not hit the limit.

you car will run fine and pull very hard and smooth without a CEL even if you are dropping like 40 bars of fuel pressure by running too much air charge.

That is a fact.

The fuel pump duty limit can be used as like a secondary fail safe or something but it's really not best to rely on that to protect your engine ...

well I do plan on running a Radium surge tank with a couple walbro 450 lph pumps ss id 1300 Radium port injection kit, aux fuel control. Just wondering why your so hell bent on being anti Hondata? Hating much?

Pretty sure he uses hondata.

He is just making people aware that running ethanol mix in a fuel system that is already under heavy constraint can be a problem.

And the comment above about fuel pressure dropping, he was saying that was on custom tuned cars running pump gas (in the 360-380whp range) that pattern already was seen, so if you throw in some ethanol mix the demand / load on the fuel system is even higher

dude ... i am not ANTI hondata. I been running hondata ever since it came out and i been running the sirimoto kit (e25 ish) since it came out ...

i'm just telling you what i see from my own research and datalogs.

Running an ethanol mix without doing any kind of datalog just because you are not throwing any CEL is not smart. I have personally seen a fuel pressure drop of 40 bars and the car still "ran fine with no issues" on my OWN car and my own datalogs. I have since then, self tuned the aircharge so the pump is happy and i'm not hitting 100%.

Tough crowd. o_O

Yes, listing IMW's e-tune service for this Flex Fuel kit was a mistake, hence why it was removed weeks ago. Derek at IMW AND KTuner both have their own reasons and beliefs for not offering or wanting to support Flex Fuel for the FK8 CT-R, which is totally fine; to each their own. Just let it be known that one is limiting or affecting the other, both companies have their own beliefs and values.

Our reasons for supporting and pushing Flex Fuel for this platform is simple; efficiency and cooler engine temperatures. As everybody knows, heat-soak with the FK8 platform is inevitable. It only makes sense to us to want to decrease cylinder temps. Also, if higher boost means increased IATs, cylinder temperatures, exhaust temperatures, back-pressure and the fact that the turbocharger is working hard(er). If these cars can make the same or more power at the same or lower boost pressures, efficiency and safety is gained all the way around, especially for track folks where every bit counts.

Why does everyone have to jump to prove people wrong here. The abrasiveness of the comment about the whole” that’s what you think”. I mean really you could have just said it like
Hey I think you should double check your plugs to be safe.

Let’s clarify something here that a lot of people are missing about uploading e30 tune
The ONLY THING YOU SELECT IS E30 TUNE AND YOUR INTAKE TYPE.
Don’t believe me ask hondata
Second the biggest missed thing is
91 octane and e30 is NOT The same final octane rating as 93 and e30. It does make a difference. Finally the last thing is reducing spark plug gap to allow better spark under high boost levels. This should have been done the moment you tuned the car in the first place.
Everyone keeps saying spark plug blowout. They don’t blow out. They misfire. What’s happening is the fuel is not burning or completely burning. It’s not detonating. That comes from other reasons. Regap them put them back i they’ll work fine and YES YOU CAN GAP THEM. I said this cause I guarantee someone’s going to say “ you can’t gap laser iridium plus” with a smirk on their face. There are tools for this so you not tapping the end on a counter and hoping for the best. STM Spark Plug Gapper Tool 14mm https://www.amazon.com/dp/B075NRR233/ref=cm_sw_r_cp_api_i_G4RoDbEMRGYMB

I honestly wouldn’t doubt it if’s someone put 87 octane in the car and 30 percent ethanol and tried to run the tune and started blaming hondata.
I have both ktuner and hondata. Both have great base maps. The things is with hondata you can add options that aren’t installed on your car and of course sone guy out there thinks it’s going to help his completely stock car and shame on them. I’m so tired of people blaming the tuning companies when over 90 percent of the time it’s something the customer did.
I’m beginning to really dislike this forum cause all people do is tell other people how wrong they are. I swear it’s loke a personal goal on civic forums. It was never like this on HPtuners. We helped each other.

Nobody is jumping to prove people wrong. If you see my posts on this forum, I try my best to help people on here as much as i can but when they come back to me saying the car is "running fine with no issues" with no data to back it up, idk what to tell you.
It's really stupid how nowadays your a "HATER" if you disagree with somebody even if your intention is just to spread some knowledge to the person. (look at the k20c2 turbo thread. your considered a hater if you are just trying to help him so he doesn't boom his shit lol.)

I have datalogs of my OWN car dropping 40 bars of fuel pressure and not triggering a CEL and "running with no issues" on their supplied flex fuel map. I've fixed that myself by adjusting parameters to keep my pump happy and it currently caps at like 95% and not dropping any fuel pressure. I will even post a SS of the data once i'm home if you don't "believe" it. The factory HPFP running out of a fuel is a fact.

It was the way it was posted. They said they had no problems which may be true.
He wrote
“Keep thinking that go and check your plugs and injectors”
No one can say for sure but it’s the approach I don’t agree with.
Maybe I’m just cut from a different cloth but
I’d say “I’ve heard a lot of problems about plugs I would suggest checking your plugs”.
I don’t feel a need to immediately prove someone else wrong in such a manner.
There’s just soo much trolling on here and soo many people who really don’t have a clue just spewing garbage out cause they read something in a forum. You sound like you actually know what your talking about.
40 bars of pressure but what was the injector duty cycle?
You capped it at 95 percent but how did that reflect your injector duty cycle? I haven’t gotten flex fuel as it’s useless where I am even the damn airport doesn’t have e85 in Myrtle beach. I believe you in what your saying. Like I said before you actual sound like you have some knowledge.
I’m curios how far you’ve pushed the turbo cause I’ve increased boost above 5 k but not much as 21-22 psi seems to kind of be the cap cause it’s so damn hot lately. Also I found but not adding mire ignition timing before 4K I can gain another degree at 5k which hondata is pretty much at max timing at the 5-5500 rpm range. I can only add 1.5 degrees if timing there but both before and after I can add 2.5-3 degrees. Also my afr is now 12 until 4500ish then 11.8 to redline. I had to change low rpm afr load enrichment cause if I went to 11.8 at around 3500 it would go too rich to 11.1 for a few hundred rpm and you could physically feel it bog down. Now it comes into enrichment slower and doesn’t overrun 12.
I’m honestly curious as to what this turbo can really put out psi wise in the higher rpm. I feel like it’s tapered off more than it needs to be cause it will make 20 psi at 7k I find it hard to believe from 4500 to 7k only a 2 psi drop?most cars would be much more significant if the turbo was out if “gas”. You cant tell me at 4500 rpm 22 psi is spooling just as fast as 21 psi at 6500. The math doesn’t add up. I know these cars bend rods easy so I don’t do anything low rpm with timing plus no need as your just lugging the motor at that point beating up bearings.
I’d like some feedback of your experience tuning cause every car has things that work and things that don’t. Have you adjusted cam timing and found better turbo spool.
One thing though this is the third car I’ve owned with a 100 percent electronic wastegate actuator and I really feel they are slower to spool than vacuum with electronic solenoid. Much slower. Again I am not trying to prove anything I can think I can benefit from some of your current fk8 experience. If it was a zl1 Camaro I could tune it in my sleep I know what works on lsa engines. Thanks for any info on advance. I’d actually would like to see datalogs cause if it’s that good of an improvement I’ll buy a 55 gallon drum. If you’ll let me I’d like to peak at your tune and see what’s different if you don’t mind?

I wonder if a new FF tune is required since the weather is heating up ambient temps?
