Can you tune on ecutek with with an eca-2 flex fuel sensor installed and pass smog?

No. To use the flex fuel sensor you would have to disable some evap codes and so the EVAP monitor would also be disabled. The EVAP monitor is required to be in either INCOMPLETE or COMPLETE state. N/A state indicates disabled codes and the vehicle will fail smog.

Aside from using a flex fuel sensor, there are other learning approaches that could be implemented using the ecutek custom programming language to determine ethanol content directly from combustion results, thus not requiring the need for a flex fuel sensor. There are multiple ways to handle flex fuel, each approach has its advantages/disadvantages.

Yeah, that's my issue right now. My evap monitor shows incomplete. My car is a 2017 and my ecu doesn't have the same (RAM) capabilities as the older years. I wonder if flex fuel programming could be done through my ecu.

It's actually not so much the ecu, it's the firmware that takes up more space leaving less room for the custom programming framework. I recently did one and I used every single table/variable that was available to implement my custom airflow modeling and fail-safes. Have you tried running an older version of the firmware? In theory, it should work fine if you could find a firmware that wouldn't trigger DTCs.

You're right about the firmware, I didn't know the correct terminology. I haven't tried an older version, that's an interesting idea though.

Could someone please give me the part # or a link to the exact air filter used in this kit?

The one I have from the accident is all dirty.
It has an insane amount of dirt in there it turned literally almost black.
I hit it against the cement trying to shake the dirt out about 500+ times and it is still really dirty.

I don't want to buy the K&N cleaning kit because it cost like $15, whereas I rather just buy a brand new one of these filters.

Please and thank you if someone has a link or part number for it.

=)

Yea 6-8 hours would be my best guess once you get used to it. You’ll get good at removing belt and blower, but manifold work and getting couplers on snug will be a pia. The guy who helped me (he’s on here somewhere) switched his out for emissions. He didn’t complain much about it but takes time. But it’s easy to do and avoid issues
But i’m about to be at the same crossroad with evap wire for flex fuel. Got ticketed for car too loud already i’m concerned they could have tipped me off for emissions suspecting modified exhaust. So that’s another fun step...

Been successful in sleeper mode so far. Will probably be keeping my Z quiet to avoid drawing unnecessary attention.

Dynoday on the heartbreak dyno (any dyno in Colorado). 402 corrected, 337 actual @7.88psi of boost. I know I’d pick up another 1.5psi or so at sea level, not sure if that’s corrected in? Hoping for another 100 or so on e85. Emissions looked great so could probably throw a little more fuel, lmk what you think.
He also noticed my dirty filter from belt dust and said he’s seen people pick up 2lbs switching to a screenguard.

Were you suggesting getting rid of your filter or just pointing out reasons for possible low boost? If your filter stopped a bunch of belt dust from entering your engine, I definitely keep it!

No more so low boost from elevation. Can’t say I haven’t seen people run the screen guard filter

Belt slippage?
 

Check out what my car's doing. Boost completely drops off at 6000 rpm. I sure hope it's just belt slippage.

I have a hard time believing this is elevation issues. I had mine there making 490whp on 10psi.

Stock pulleys? Only thing I’ve changed up is impeller. Logs and dyno dont really look like slip to me. Idk how likely i am to be leaking. Would a tbatt kit not work as well on stock pulleys?
Will definitely be changing up pulleys next year but for now trying to enjoy newfound boost. Sure puts some pressure on quite fast cars

Oh, I thought you had a similar setup to what I was running. Guess what matters is real world experiences. Good to hear!

Hey guys!

My car is slowly being put back together..


A couple issues I ran into:
1) I lost my modded high pressurized overflow tank... anyone know where I can get another one or the part number for it?
I have the 2009 model 370z that is going to be the new body instead of the 2015 which was the Z that was wrecked.
Apparently the 09 model - 11 models don't have the pressurized coolant reservoir...

Anyone have ideas on how I could get around this to fit the TopgunZ A2A kit properly or nah?

2) No idea where the PCV lines right under the throttle bodies led...can't remember!

3) I don't know how, for the life of me, to remove the 2009 rusted ancient dinosaur fossilized demon bolts from the cat to the headers...lol. I need that cat but to get it I must remove those bolts. Any ideas to get it removed?


PS -- Is it possible to run this kit without an overflow tank in case I can't find one, ever again? T_T I have a regular overflow tank (not pressurized and not modded either) but I guess that one won't work?

Please and thank you for answers / ideas / tips / advice , etc.

Dang. Hecka lot. I actually found one on Z1 just a few minutes ago for $80 something haha.

Can order the late or earlier models too as an option for no cost extra.

I suppose there's no way around this but to get another one huh? Haha

When I measured my 9psi pulley I bought form ConceptZ, it came out to be 2.87" instead of 2.75"?
Where do you guys get this 2.75" 9psi pulley from that goes on the jackshaft serpentine side?


Also.

I see 928 offers the sur-grip for their pulleys but has anyone actually tried it for a DD?
I would assume it makes belt dust since it would eat up your belt making the belt's life span shorter in the long run no?
Yeah they claim to make your pulleys life last longer but probably at the cost of the belt I'd assume?
Or does it not make much of any dust over time?

The 9lb pulley is a 2.87

Your second question I answered in the PM you sent me. Other's might want to comment on their experience with them.

Thanks.

Just wasn't sure cause I saw evan's post say his was like 2.75 or something and I am pretty sure I saw another post saying it was less than 2.87 lol

Just stay with the 2.87.

Agreed. I am also curious about the source of the 2.75 one. SOHO may sell the (2.75) pulley/belt combo but it is barely needed to have a smaller one like that if you stay with V-3. The 3.47/3.0/2.87 will get you way out of its compressor efficiency. I did ask my friend to customize a 2.8 serpentine side jackshaft pulley for me just in case, though!

CupcakeZ you can PM me if you still want a smaller one like mine (custom 2.8). I may never have chance to actually use it.

I need all the pulleys according to my map sensors im only making 4.5lbs of boost even though when we put an analog gauge on the vacuum line or dyno it says 7.8lbs i can tell my low boost is driving seb nuts

I'll PM you for the 2.8"

I might try a 3.6" Jackshaft SC and a 2.8" direct SC pulley

Should you use 3.6/2.8 supercharger side combo paired with my custom 2.8 serpentine side jackshaft pulley you will overspin your head unit to about 71500 RPM. This is highly likely to get you up to 20ish psi.. Are you sure you want to do this?

I believe he want's to use your custom 2.8 for the sc side but still use the 9lb (2.87) on the serpentine side. He'd still see close to 70000 rpm.

The number of rib is different for the pulleys at different sides. I haven't tried putting mine on the supercharger side. I doubt the 8-rib SC belt can fit it.

On the calculator from vortech website regarding v2 and v3?...
It asks for number of teeth
You guys ignore this and just put diameter anyways or?

Cuz we dont have teeth on the pulleys we use, we have ribs, right? And typical 8 rib pulleys on both sc belt side and serp belt side? Or im wrong?

Yep. That. Lol

I recall the serpentine side belt is 7 rib.

Oh lol i never really counted it.
Good to know ! So the 9psi pulley on there is 7 rib then?

Yes it is in terms of our serpentine side pulley spec.

Supercharger Kits - $5750 Shipped!

Guess I should buy now! Sign me up. I also need 1050cc Inj, and P&P adapters. $675 and $60 for those?

I'll email you!

The injectors have gone up. I emailed you.

I am very interested in this kit. Looks like the overall install effort is moderate for a weekend wrench turner. Is that correct? Generally how good are the install instructions? What is everyone using to tune the car once the install is done? I would to see more pics of the kit installed with the front cover off.

Very easy install. As long as you have a decent set of tools you can easily knock this out in a weekend if you know your way around the VQ a bit.

Here's another front end shot.

Good to hear. Any chance I could get a copy of the install instructions?
