Maybe ryephile got a bad batch....how did you get them flow tested?? ? I have a set of helix 380's in the mail and dont wanna go down to florida to be running lean....

17 bucks screw that....Just hope ryephile got a bad batch ...anyone else had this problem with helix 380's???

I don't even want to know where you picked up that nonsence from, Ryan.

 

So is this false....someone said that tuning with them is harder?

 

The nonsense started when I installed them in my car. The long fuel trim needed very little time to adapt; a sign they do not flow much more than stock. Instead of taking many hundreds of miles to trim out it took about 30 miles.

The nonsense is also straight from my AFR charts during Jan's tuning session. He was adding fuel to the mapping and the injectors were not responding. Jan also had a tough time tuning them as they would react erratically to small changes in the mapping. Perhaps I do have a bad set, but they were a pain to tune and flow barely any more than stock. They appeared to be running static by ~190wHP, only about 5wHP more than stock injectors.

 

Well know im not sure what to do....I dont want to drive 8 hours and speend 500 bucks to get a tune and not get everything i want out of it...helix is it possible to send them back and get JCW 380's?

Call Eric directly instead of asking him here.

Longboard

 

 

i never hear it slip , i asume it would be a noticable noise ? the belt has been on the car for less than 4000k .
i plan on doing a new belt some time this summer , i want to go for a 2% crank pully. (after fixing this problem)

 

i have 2 or 3 emails into helix asking for help , but they never got back to me. i am sure if i went back to the stock ecu setup it would be normal or close to it. the giac tune is nice and i want to keep it . i think i will go for a new fuel pump .... i think it will solve my problems. i just need to find a place to buy one.

 

The MINI's fueling system is returnless. If you go aftermarket with the fuel pump, you'll have to swap over to an old-skool return-line fuel system. This means new rail or mod the stock one.

I understand your desire to keep the ECU flash, as I'm sure it gains you better drivability and more power, but at this point it's probably hurting as much as helping your butt dyno if the car is pinging off the hinges.

 

Yes it's noticable. There's a stumbling sensation to acceleration(for me upwards of 5500 rpm) coupled with an interrupted sucking sound from the intake!

A friend of mine owed me a favor and got it done at his shop for free.
And they are radical, no tuning issues with mine.

 

How were you measuring duty cycle?

When (if) you datalogged Long Term Multiplicitive Fuel Trim, where the peak mS readings?

After the thirty miles you drove, what did the Relative Long Term Additive Fuel Trim read as a percentage? 0?

If you don't have this information, you're just guessing at your fueling problem, and blaming the injectors. If you infact did do the above datalogging determined there was a problem with the injectors i.e. they're not flowing as advertised, you should have called me so that I could test your injectors, and replace them if they were faulty. We have had these injectors tested twice by two different facilities for both spray pattern, atomiziation, and flow. We wouldn't sell them if they didn't perform as we needed. Apparently, lkbindustry also tested his.

You, as one of the more respected members of this forum, must understand how a post like this impacts a product. By making a categorical statement such as the Helix 380cc injectors "don't flow as much as they should", It creates 'internet truths', and hearsay becomes NAM gospel.

 

perhaps Jan can shed some light since he tuned the car

 

Very true. If I had seen a statement like that from a well known member or other vendor, I would have definitely thought twice about my purchase. And if Ryan didn't do the proper tests to prove it was the injectors fault, then he shouldn't post such a claim. His comment could greatly impact ones decision on buying Helix' injectors... And possibly make those who already have them worry when they don't need to.
I'm not sure what I am trying to say.. But you get the point.

 

I never said I measured duty cycle, however when I'm watching Jan repeatedly add more fuel to the ECU flash and the AFR doesn't change, it is simple to deduce they are running static. I understand his position to not comment, no hard feelings. I'm not going to measure duty cycle because it's not convenient and it's clear to an experienced person that when airflow goes up, fueling needs to too; when it doesn't the AFR goes up. Plain and simple.

I did monitor my Relative Long Term fuel trim, but not immediately upon starting the car and letting it idle for 15 minutes. I didn't look because I shouldn't of needed to; bigger injectors need to trim out and that takes time. My scan-tool monitors short and long relative trims in % of course. I did look at the scan-tool every few minutes during the initial burn-in drive. It took about 30 miles of very mixed style driving for the Long Term trim to get to -1%. I consider that close enough to 0%. For reference, when I used 42lb/min injectors on my single-turbo car, it took 150 miles to trim them out to approx -1%. Clearly a major difference in adaptation times, which implies a big difference in flow rates.

Based on power output and injectors used of other MINI's during the December tune party in Michigan, the JCW 380's flowed more than the Helix 380's, which flowed more than stock 330's. Perhaps the JCW 380's are underrated and are closer to 400cc/min, I don't know.

Eric, I understand how you may have gotten irked from me posting my experience of your house brand injectors. I'm not saying your injectors are crap, they are still in my car and my car is tuned very nicely and drives great with them installed. You know first hand how I don't BS and I'm especially not going to put garbage on my own car. Your injectors have a specific niche; they flow more than stock for less price than JCW 380's. There is certainly a market for that.


...and you can believe I wouldn't have said anything if I lacked the wisdom to make such a statement. I want to make a specific point about the word "fault". Keep in mind the power they went static was richer than the system needed to be, and for a very tiny RPM band. I wouldn't say it was anythings fault, just that they're close to being at the threshold of having to back off the ECU tune aggressiveness.

Peace,
Ryan

 

with that many miles you could try seafoam it does work!!!

 

Well..I know that Marren setup is on THE list....

 

Ryan,

You said: "If you're running Helix's 380cc injectors, you're probably starting to run lean because they don't flow as much as they should".

This is a false statement which is not supported by the circumstantial data that you have presented. You have not done tests that support this statement. As I said in my last post, you are creating an 'internet truth' based upon your conjecture, which is false. As I predicted, littlehandegan emailed me today, wanting to exchange the helix for the JCW injectors, which I am happy to do (we make no money on either: the margins are so small), but the expense to him is because he believed your false statement.

Herein lies the double edged sword of internet forums: speculation (from vendors as well as members) becomes truth at least for a while. Usually, the truth becomes apparent over time. I'm hoping it does in this case.

 

Eric, I sent you a PM. Your claim that I have not done tests to back my statements is conjecture and I won't tolerate such sloppy comments on your part just to attempt to discredit me. You have parts to sell, and this is my hobby. Since you claim you make "no money on either", then I recommend dropping the house-brand and just sell the JCW injectors. Streamline your catalog and improve customer service perception.

 

In either case you 2...there will be no babble in The Church Of NAM. Quit it or I will ban you to your corners..

 

Hey Rat Blast, did you ever solve this pinging, stumbling, hesitation issue?
I get the pinging if I floor it aggressively, it does not occur when I press throttle progressively (kinda roll on the throttle). On Cold or wet days the pinging kinda subsides, as well. What did you do? Sorry, but did not want to revive thread, cause there was some quarreling. I am getting retuned and 440cc injectors to see if it resolves, but wanted to see what worked for you.

 

i was dealing same issue. my fpr was clogged with crap put new one in and its all good
