Rep Power: 280

Hi all!
Here is the pic of my dyno run I made today.
My kit: TSI extreme / t-25 no BB @ 8psi / fuel system: tsi injection unit with 2 extra injectors / 94 Sunoco gas /
Dissapointing 158 whp / 169 wtq - possibly due to spark plugs, I had Champion copper OEM replacement (could'nt get anything proper intime for the run). - lost few horses (???)
reg of A/P: the shop had problem with w/b sensor, it was getting mosture and was giving inconsistent reading after 3500-3800 rpms. Whould of been OK if w/b sensor was making readings from the downpipe and not muffler tip....there was no time available do do more runs, but I want some valid opinions and facts from you dear members.
I dont understand what happening at about 4k rpm point - suggestions (???)
TQ numbers seems to be too high in the midlle and falling off with rpms(???)
HP falls off at 5500 rpm (t-25 fault)
Tell me what you think fellows???

What can I do for the tunning?

Well the numbers aren't too good, but it shows hope.

the dyno run pic is up, sorry frogot!

Horsepower falling off sounds like lack of spark or lack of fuel (or maybe too much fuel). What step plugs are you running? Pick up something that's a step 7, that should be a good starting point. Also, the turbo the tsi kit uses is a pretty small turbo, I wouldn't expect anything too big out of it. Maybe an upgraded turbo will yield better numbers, too. I think this is a perfect example of how different turbos flow different cfm at different boost pressure, though.

looks like a lack of fuel. your A/f ratio goes off the chart.

that explains the fall in power. It is not due to a small turbo.

Check your spark plugs for detonation. Add more fuel after 4k.

 
Rep Power: 284

actually, it looks like it goes extremely rich, then goes extremely lean.

Maybe you are adding too much fuel, the injectors get maxed out at 100% duty cycle, the injector controller doesnt like this so it takes out a bunch of fuel automatically in order to keep it from burning up.

Thats the only thing i can think of that will give a drastic change in A/F

Plugs are stock specs, copper champions. could not get anything better on time.
But still t-25 should yeld more HP!. gen 2 talons and sr20 have same turbo and get at least 200 crank hps stock.
Thats why I think I have to be at least 10 hp's more with better plugs and (forgot) silencer on the muffler. Am I right or no?

 
Rep Power: 280

A/F graph is a bit off after 4k rpm, due to moisture getting on widenad sensor during the run...
But what's happennig at about 4000 prms (from the graph) ???

Sounds like you are in desperate need of a good tune!!

 
Rep Power: 335

get a tune with some iridium plugs and what about the A/F ratio? how are controlling it, controlling the boost?

 
Rep Power: 269

saw someone on this site gettin 200hp or so with the tsi extreme kit so who noes. but its prob something which the other guys said. gl with it nd keep us updated

holy lean mother batman!!!

 
Rep Power: 349

Ok, I could finally see your graph. Stop boosting the car now if you want to keep your engine! You are ridiculously lean from midrange to top end. I don't think a little moisture is going to read you at over 16:1. You whould be more around 12:1.

Do everything both I and turboengnr said and you should be making alot more power.

How plugs would look like??

Thats the whole thing, reading becomes inaccurate, a/f w/b sensor was at tail pipe, temp outside was at +5C.....
We played with fuel wee added it, redused it... and after 4000 reading always jumped from 10 to 18. You have to be suspicous if no matter what you do, reading not changing.
Is is cold weather problem???

....TSI Injectors are at about 60% duty cycle.
I drove with more/less same setting for over 6000km now.

I think you need some SERIOUS fuel tuning. Your A/F maps are ALL over the workld. They should like the black line on this:

 
Rep Power: 280

^^ I dont disagree with you or any other member who mentioned a/f tune.
Guys, I'm on your side!
Now, I'm concerned with power dip at 4000 rpms.
I want your opinions on it.
I have stock fuel pump. Could it be it???

 
Rep Power: 0

The dip, I think, is caused by the improper fuel. Look at your A/F graph at that same RPM. It's all over the place. What injectors are you running?

 
Rep Power: 280

The guy at the dyno shop said he had problem with w/b that day.
Its TSI 2 injectors and control box.

 
Rep Power: 387

I have the TSI extreme kit and put down more so I gotta agree you need some adjustments but I'm also running the Iridium IK 20 Step 6 plugs. I had issues figuring out the fuel at first to but have since gained more knowledge and figured it out.

anyone have any experiance with using power enterprises vtec a/f controller? im havin similar problem as when engaged it stalls my engine totally!

sorry to bust up in the thread, but i can seem to find any help with this!

nickd@sti-k12.com if you have any help for me. dont want to fuxorize this thread

 
Rep Power: 280

Do you run your fuel with tsi injectors and control box??

 
Rep Power: 0

a turbo setup is 5% parts and 95% tuning.
I'd go out and buy an emange at minimum, but I would really go buy AEM EMS.

 
Rep Power: 280

Start your own thread, its not biggi

 
Rep Power: 335

dude a aem ems is the same price as a turbo

 
Rep Power: 0

i have made one, with no response, figured being tuners replying in here i might get some attention =P

 
Rep Power: 280

AEM AMS cost 50% of the turbo kit.
Common, you have to know where to stop.
For a street use by an amateur e-manage or tsi injectors just enough.
Agree, e-manage is more flexible with tunning, but TSI box does job just as good and its also very simple to set up and get going.
I do think now, that my fuel pump is the problem, sometimes I hear whoo-whoo-whoo sound comming from the back of my car. I thought it might have been wheel bearing, but after my dyno yesterday i realised its possiblt the pump thats trying to tell me something.
What walboro pump do i need?

 
Rep Power: 335

look there are plenty of a/f controllers that include vtec engagement and shift points if your automatic. EMS is all about track **** or if your horridly rich. not worth it unless your sponsored or something.

that's the problem with honda drivers, no one understands that turbos cost money.
$1400 on the AEM EMS is CHEAP, and 3000 on a turbo set-up is real cheap,
I'm looking at going turbo on my BMW and the enigine tuning is the TEC3r which cost's 2,750 + the tune, the turbo kit I'm doing myself so it will be about 4000 dollars plus cost of the TEC3r.

I know honda's are a little different and cheaper to do things, but I'm just stating that the AEM is pretty cheap considering other cars.

I like to say when going turbo you can only pic two of the three:

speed
reliability
cash
