CLOSED: Cyborg TurboCharger * NOT AVAILABLE *

You are forgetting you are also comparing stock turbo on 93 to upgraded turbo on E30. Just a small detail

Overlay a 93 Oct plot.

I could post the 93oct car making more power than me... But its not my place or car. But I do agree, I did forget about that. Like I said, I took the easy way out in tuning the E30 first since its so much less technical than the limits of 93oct. But I'll get there someday

I'm just saying if you are going to compare in detail those data points you did, it would be a good idea to mention the fuel differences too. Not that I am trying to diminish the turbo at all, just the data junky in me likes to see these types of comparisons with full disclosure.

Do you have the 293tq log/graph to share from your signature number claims? That would be interesting to overlay with my 300+wtq stock turbo graph.

No your right. I was thinking at the time of all the "installs", and "nuts and bolts". Didn't think about the E30 at the time.

 

[Sourskittle]

Did a log, its warm by US standards right now ( no jackets or pants ). I think its 70 degrees with the sun down. Anyway, logged it and it seemed nothing changed with the timing added down low. So... I looked a little harder and.... (Slaps forehead) the timing change I made was done at 2.0 load. Checked the log, and that lower RPM area on my car is 1.5 load and doesn't hit 2.0 load till pretty late. So I made the changes again, but at the lower load, so I'll try again on my way to work in about 8-9 hours

 

[Sourskittle]

The graph with two plots on it is from tonight with 68 degrees on the dash gauge.
the other graph is the one razor wanted to see, I just saw his post from the other day. RPM wise, its still not making it as soon.

raw logs up for those two dynos. http://www.datazap.me/u/Sourskittle

The last 238hp log for 5-10 days ago was from when it was dry and 44-47 degrees here. Its 9:50pm here and I'm outside in a tank top, shorts, flip flops and I live on a lake, lol. So I'm happy with that. Looks like its going to stay warm until 2-3 days after I dyno the car again Saturday.

Razor, I'm going to try and find the raw log of the 293tq for you. It was wicked cold that morning.

Other less measurable notes... Because its so warm here right now ( not crazy hot ), I put in some limits of my own based on charge air temps. When the temps get to 97 degrees, it starts to reduce timing a bit. When the charge temps get to 100 degrees, it reduces the boost via wastegate duty cycle, but only a bit. Just to keep it safe in case I'm beating on the car and get carried away.

Also... I'm reduced the wgdc in 1st gear to about nothing, lol. And pulled the power down in 2nd gear via boost as well JUST A BIT. I did two different 5-mph roll to 80mph pulls today. One during the day, the car felt faster than its EVER felt at the track. The second time the temps had cooled down a bit, and it spun just a bit. But keeping the wheel spin down to about nothing in 1st gear makes 2nd gear come on smooth and crazy hard. Its nuts to the top of 3rd. Next trip to the track will prob be way more about 60ft tuning than power tuning...

 

[Sourskittle]

razor found that log for ya

 

[razorlab]

can you plot the boost and afr too?

 

[razorlab]

I told you that you might make more power with less boost.

 

[razorlab]

Here ya go, some overlays using those logs.

My stock turbo on E40 vs your Cyborg turbo on E30? with big boost.

Green plots = me
Red plots = you

You comparing me on less boost

Green plots = me
blue plots = you

About a 40whp difference up top. Seems like that turbo is finally performing with some real tuning.

 

[Sourskittle]

I'm pretty impressed with it. Seems like its coming together. As far as its come, it has a lot of holes in the boost PIDs and stuff. Its doing what I want it to, but I guess its not coming about in the correct way? Kinda like when you'd tell your math teacher the answer, but she was more interested in "how you got the answer", then the fact you got it correct, lol.

The timing is topping out at 17 degrees, that's prob a little low on e30. Maybe when the temps drop, it will run more automatically.

Driving to work tomorrow, I'm going to feed it a bit more timing ( 1 degree global, above 1.8 load, then 2 degrees global above 1.8 load ). I'll see how it does.

I'm volunteering to go get everyone in the shop lunch for an excuse to get a few logs in during my work day, lol.

I'm def chewing up some gas too. Filled up Saturday and I'm about to need gas, and I drive like 8 minutes to/from work, lol.

 

[razorlab]

I think 17 might be right where you want it with that boost.

Tuning boost with these modern systems is pretty complex, as you are finding. It takes awhile to get your head around it but you will!

Btw, you can run the car leaner at cruise with Ethanol. It helps with the mileage. I run mine at 15.4 and have seen a 2-3mpg gain.

Cyborg upgraded stock Turbocharger system

I'll post up the raw log later ( no wifi at work ), but that's a pretty nice power band for me.

63 degrees on the dash with a fair amount of humidity.

It made 267TQ peak

Note-worthy numbers...

200tq 2560 - 6450 rpm
250tq 3200 - 4800 rpm

200whp at 3900rpm
217whp at 4300rpm
230whp+ 4800 - 6500 rpm

 

[ryst]

SS your new avatar is still freaking me out. Any backstory on it?

Also it's nice to see the gains you're getting, you still planning on getting it pro tuned?

Q for razor, why can you run ethanol leaner at lower load levels? Is it because it's more knock resistant?

 

[Sourskittle]

Actually, the avatar is a pic my GF took of me, but I didn't expect it to show up with such "HD" resolution !!

On the other hand.... The undie's do have an "S" on the them for Sourskittle.

I am going to have panda do a pro-tune for me. They said my timing and a few other things could use some work, but right now I have 4 kids and Christmas is weeks away, so its gonna have to wait

The biggest area I'm going to need Panda at is the 93oct.

I was just fixing to ask Razor, when I do go back to "the gas or mere mortals", which should I look to reduce more, timing or boost?

Timing for sure.

Q for razor, why can you run ethanol leaner at lower load levels? Is it because it's more knock resistant?

Ethanol burns better at leaner lambda.

 

[Sourskittle]

I won't hold you to it, but how many degrees you think I'll loose? I'm fixing to fill up with E30 again in a few minutes, but I'm just thinking ahead.

Remember this chart I posted awhile back? More for the delta than actual prescribed numbers.

 

[Sourskittle]

Your the chart master !! Lol. That's a pretty awesome example !!! I realize it wouldn't be the same, but its prob fairly close.

 

[Sourskittle]

This is the log from this morning. The raw file it also on datazap

Cyborg upgraded stock Turbocharger system

This is the good news ( I will be bringing my usb drive !! ).

This is the bad news ( for me anyway). I will be running a log before I get to the dyno to get a feeling for how close they are.
(Bad news being its hot here today and will not cool off till like Tuesday).

I weighed the car before leaving work a few min ago and its 2740lbs the way I daily drive it.
