It might have been an exaggeration on their part, but you have to admit that most of your posts in our threads are in violation of the forum rules.

More importantly, what fuel system was on the car that you dyno'd in your post on the last page? What fuel?

 

It's comedic even with that said, he continues to post.




John, I think it's time to move on.

 

Matt,

I’m getting what seems to sound like quite a bit of compressor surge between shifts. It might even be wastegate chatter? Any reason why the ZFR is doing that and how to quiet it down?

 

I would recommend watching the cam phasing under those conditions to look at the possibility of excessive valve overlap causing the problem. You could also make adjustments to the bypass valve table to allow the turbo to bleed off pressure sooner. It could be due to other components in the system as well.

 

Yes, and only to hate on zzp, never to actually engage in a discussion about whatever he brings up. I clearly attempted to discuss injection timing with him as it pertains to the setup he was tuning. Instead of participating in a discussion, he simply disappears until next time he feels like putting in a bad word for zzp. It's unfortunate because he would have some useful knowledge to add to such a discussion, but he chooses to act like a troll instead.

 

Well its October all the trolls coming out

 

lmao

 

Valve overlap stays between 40-50. The flutter noise happens consistently after about 4 PSI with higher pressures just making the flutter louder. I don't remember hearing this noise before you tuned it. Not sure how to adjust the bybass valve table. Is it the nut on the wastegate you're talking about?

 

Ahh, sorry, I didn't recognize your screen name at first. Since I tuned it, I will check the logs. I didn't run into anything like that when I road tested it, but it does sound like it is overlap related. As far as the bypass valve table, I was talking about a chart in the ecm.

 

Well InfraRedline (Taylor) tuned my car today....E47 on 26 psi.....pulls very strong and he kept it a little on the conservative side just to be safe. Overall i am very happy with the tune and the car.

 

^numbers?

 

He just tuned it.how.would he have numbers

 

Patiently waiting for boost for boobies.....Gonna be a mean dyno run

To clarify it was Street tuned....not dyno tuned

 

If I'm back.by then it'll.be a dual who.makes more power Idk if I'll be back for it

 

thats what taylor kept saying....he said it would be damn close

 

Ill come and play.. Let me go get my go cart with a 50shot of weed wacker juice and my 200shot of nitrous (only for 4hp Honda engines) gotta ride dirty.. Lol ...

 

he could have gotten it dyno'd after tuning?

 

no dyno till around April

 

he just made it sound like it was impossible for you to have dyno'd it the same day as tuning it

 

Dear serega12,

First- I agree, and I had no intention to be hateful. Good job sticking up for the forum!

Second- I have no intention to become an authorized/reputable tuner, I'm not an expert nor good enough to do it. And there is no way I would make enough money tuning. This is just a hobby.

Third- I don't see how I was being hateful? I read my post 4 times, and I just don't see it.

Forth- I've tuned on a few ECU platforms, single, and multi carburetor setups and worked with experts from 80 year old tuners to the engineers that develop future ECU systems. The one thing I've seen everybody do when they find a parameter that makes a little power, is tune for that parameter. That kinda worked in the past when ECU had one map that it always used. But these Bosch DI ECUs have multiple maps for different injection/power modes that all share some parameter tables. Tuning for these ECUs means going back to the basics and starting from scratch testing every combination of changes. But I'm not an expert and probably don't know what I'm talking about.

Fifth- I have purchased ZZP products and enjoy them, although I wish they communicated better, but I'm sure they are very busy and I probably just feel through the cracks.

Sixth- I enjoy and appreciate GMTechs posts they are often filled with great information, superb questions, and an amount of intellectual cynical bitterness that reminds me of Oscar Wild. Wish he replied to PMs also... maybe my PC is broken...

Seventh- GMTech might be a little bitter on this forum, but I can't blame him. I'd be bitter if my posts got pulled and I got sent the same message he did. On the other hand a little tact when posting on vendor threads is a good policy. But someone has to question vendor claims and results or we'll just have $50 single wire "black boxes" that "add 80hp and 20mpg" like eBay does.

Eighth- This forum does get a little immature at times, sometimes it's funny, sometimes it's irritating. This is probably a result of the age group differences between Cobalt SS, HHR SS, and Kappa Sol/Sky owners. I just learned to skim the BS for the bits of good info that's hidden in the mix. This is my example: https://www.cobaltss.net/forums/2-0l...harger-283313/

Ninth- I can't believe I wrote this long of a reply... I really don't care this much!

Tenth- 10 seems like a nice round number to finish on, so lets all put on our big boy and girl pants and stop taking things so F#cking personally!!! This is the internet remember!!


Thank you for your time,

--Christian

 

where in atlanta are you?

 

It was a blast man! Very impressed with the turbo. The spool time seems to good to be true, but it really is as quick spooling as they say. It hits like a stock turbo, but pulls harder and harder all the way to redline. No more than 22* of timing up top, as we kept it a little on the safe side. Mad props to ZZP. I know what turbo ill be using if I decide to turbo swap my car.

Will have to do some dyno runs, track runs, and street runs

 

Let's just be clear that anything useful that he posts is not a problem. The problems start when he jumps in a thread posting obvious BS. Look at page 87 where he came in to post pictures of someone's home made castings to try to compare them to our exhaust housings. It's crap, and he knows it. That's why he gets reported. His post yesterday I can live with. He came off as arrogant and rude, but if that works for him, then so be it.

 

What are the limitations of the stock internals? Should anyone really be pushing those past 400WHP?

 

I've come to realize that this question is difficult to answer. I had thought you could just say Xwhp should be good for this motor but some people make really high whp on stock motor (Ford comes to mind) and then others break stuff on stock turbo. Some people bust transmissions on much less (I did on the BNR) and others seem to elude death so to speak.

I think the answer should be, "Roll the dice and find out."
