13+ psi on c30 kraftwerks kit? Should I be worried?

Then why was there a post where he posted a picture of injectors unless the kit came with them but did not get installed on his car?

The kit I bought was used and the previous owner was running e85. I am not in a rush to run e85 so I left the stock injectors in for now. Still collecting the rest of the parts needed to go full e85 though. I only posted the injector pics to see if others could tell me what size they are.

Got a new tune revision in and did some logs yesterday. Unless I install the larger injectors, I'm probably at the end of the road with Delicious since the duty cycle is maxed out before redline. Since I already have the larger injectors, it's a no brainer to go that direction. When I collect all of the flex fuel stuff I think CSG is going to get a crack at starting a fresh tune. I should have just gone that direction to begin with, but the Black Friday deal was too good to resist.

Kinda strange on pump... Most ppl run out of fuel once they switch to e85. Look at Moto East FF kit cheaper than DT or CSG kit

But if you have e85 common in your area do it asap. Still does not explain why your making more boost on a pulley that should only be making 9-10psi max

Again, he s not making so much boost more. It s because it s cold outside and he s getting that boost only at highest rpm with 30/30 cam timing that are kinda restrictive. Also MAP sensors, specially the 3bar OMNI, are far from perfect and can measure a bit wrong
Also, at what rpm/temperature do Kraftwerks rate that kit? it s not a turbo with a fixed wastegate-controlled turbo. It s a centrifugal supercharger.

He doesn t run out of fuel, he runs out of Port Injection fueling, because his tuner set too much PI and it doesn t want to fix apparently for obscure reasons

I'm all for saving a buck, but for a little more I'd rather have a Continental sensor than the Zeitronix. I'm going to try to pick up a FF kit used which could save quite a bit of cash if possible. I have e85 available to me a large amount of the time, so it's worth the upgrade.



The tuner with Delicious said the higher than advertised boost amount is common with the KW kit, and didn't seem worried about it in the slightest. I honestly don't know if that's true or not, but I assume he's more qualified to come to that conclusion than myself.

So I did a WOT pull Sunday and ambient temp was around 55-57 F. Boost peaked at .8 bar so I think you are correct. The more the temp rises, the better odds of my boost rating being closer to the 9 psi rating of the pulley.


The tuner said "There is also an issue in the EcuTeK software were when the port injectors reach 100%, they will roll back to 0% and go up from there. You can see it in the log."


It's there in the logs, and shows exactly where my lean spike starts. Whether he can tune it out with the DI or now won't matter if he's not willing to. If I toss in the larger injectors to fix the situation now, that's just what will have to happen. I'll ring up Zach with CSG when funds recover and see what can be done to get it all buttoned up with e85.

Also, what MAP sensor do you recommend if the Omni 3 bar isn't that great at doing it's job?

That much boost on 91 would make me think twice but the blower makes it very smooth vs turbo and all the tq down low. I hate driving my car on pump with the 69mm pulley which is said to make 12.5psi. I normally baby it till it get some corn back in her.

I reached on purpouse 100% duty on PI on my brz, it s probably a bug in ecutek of your american calibration because i do not get it.. euro bases are more stable somewhat as steve99 said
Anyway it s just a calculation, do not care about it, what important is, it s the opening duration

About the map, i don t know. I also use the omni because i don t know the alternatives, but i tried swap it with other 2 omni 3bar from friends I tuned, and they all measure a bit differently... not that I care that much in the end

that tune makes me puke, lol
shitty maf scaling, shitty SD scaling, the DI has so much headroom still and he doesn t use it, the throttle body is wrongly managed, it closes a bit at 4k rpm, the cam timings have so much overlap at high rpm for a catless header

Tomm.brz can I post a log and have comb through it. Also have validation the tune looks as solid as it feels. I am pretty sure Zach at CSG does a good job

yeah link it and i'll tell you what I can see from it no problem

Pleeeease stop running these logs mate, you are going to blow spending that much time at high RPM, high boost and extremely lean. Set up a sensor or something so you don't keep running it all the way. Your engine is crying.

In that log once again you're playing a very dangerous game.

I would just baby the car and go with Zach. He will take care of you. One size fits all tunes suck for this reason. Don't do any more WOT pulls and keep revs down. If possible CC the tune now with CSG. I rather have a safe running car and no e85 than a blown motor. My 2 cents.

I'm not doing any pulls for now. I definitely need to get a gauge setup, and am totally cool sending the work over to CSG. I just don't have the funds. Granted I'm really gonna be screwed if I nuke the motor, so not the best excuse. I appreciate all the help from everyone, it's pointed me in the right direction of what's next.
