ECMlink not as much hp as expected

[90 Talon AWD]

can anyone explain why im not peaking 350-400hp on my setup? im runnung 93 pump gas...

 

[Bud92gsx]

Where is link does it calculate hp?

 

[tron2119]

Link is just an estamite. Also, for it to estmate correctly you need to do a solid 3rd gear pull from 3500rpm to redline. Not ripping through the gears.

You are flowing almost 46lbs/min with quite a bit of timing up top for 93. Should be making some power. How does it feel?

Bud- 324hp and 319ft/lbs

Well, how much power are you putting down? Dyno sheet?

In 3rd, OP is only flowing 38lbs/min (ish) and only took it to 5700 rpms.

Based on that airflow, and "normal" drivetrain losses, you aren't all that far off from what I would expect (in 3rd any way; 2nd looks a bit odd). You should get quite a bit more airflow out of the 20g in 3rd if you wind it out.

Is your weight value correct at 3400lbs with you in it?

***

BTW - You are pretty lean for straight 93 on a smallish turbo with no WAI...especially with that much timing. AFR's during 3rd are averaging 11.7:1, with a peak at 12.1:1. I'm surprised there isn't any knock showing up.

 

[big_d]

I agree, you're pretty aggressive on AFR and timing for 93. Whats the butt dyno feel like?

 

[Calan]

After looking at your log some more...

1. Are you purposely using anti-lag?

2. Why are you clamping a 2G MAF signal at 2000hz, yet no adjustment has been made to the simulated SD table? I'm guessing your airflow readings above 2000 hz are inaccurate. I wouldn't think you would need to clamp a 2G MAF in your 40-50 lbs/min airflow range.

3. Why are you using the fuel and timing sliders rather than targeting DA table values for timing and fuel?

But where does it estimate it..I went through the logs..Maybe I didn't go into the right thing..

Ahh thank you good sir

1. i have anti-lag activated but i never launch it unless im at the strip

2.i dont understandwhat your asking, im not running SD, im running a 2g maf,

3. i will start using the DA tables all the time insted of the sliders


and do you think that is lean for my setup? ive put it at that because it wants to spit out the black smoke at wot idf i go any richer,

and none of my freinds really have any cars making over 200hp, so im not too sure on the butt dyno, im just used to it so its hard to say....any suggestions are greatly appreciated
and i usually pull it around 6400rpm because it just feels like it falls on its face, ive heard that the stock IM starts to choke at 6.4k

 

[90 Talon AWD]

i did another 3rd gear pull...any advice?

 

[big_d]

How accurate is the datalogged AEM value compared to the gauge? If they agree, then it appears you have a bit of work to do... Your DA table is targeting 11.0 for most of your power band, but your actual AFR is right around 11.7... I would flatten the fuel and timing tabs and soley use the DA tables for fuel/timing adjustments. Unclamp your MAF, and work on the MAF comp tab to dial in your AFR.

 

[90 Talon AWD]

thanks, im gonna work on that today

 

[DeadlyScone]

thanks, im gonna work on that today

let us know what you find out, i feel the same way except i am approx. 100hp behind you on my 3rd pull running 660cc injectors and an fp green spec turbo @ 14.6psi & GM 3''

i'm running a stock IM and rev to 9k

 

[90 Talon AWD]

well what can it be then? it feels so rough starting at 6.4k, i can feel it in the petal it vibrates like crazy, and if i pull it past that in first it just feels completley out if the powerband like im overwinding it,

i got all m y sliders zero'd out and am using maf comp for a/f ratio, im only using the DA tables now, but i dont understand how my hp will be better when my a/f is correct and im running all the timing it can....i just dont understand

 

[C_Keagy]

Proper AFR's and use of timing makes more power.

 

[90 Talon AWD]

what would be my optimum a/f ratio? at WOT?

 

[DeadlyScone]

what would be my optimum a/f ratio? at WOT?

and correct timing at WOT?

 

[90 Talon AWD]

ive heard for timing you want high teen's low 20's,

Every car is different; you need to find the right combination of AFR and timing for your particular setup.

Most cars seem to like something around 10.8 to 11.2:1 on pump gas, with 15 to 18* of max timing advance. But some cars will run better with a leaner mix and less timing, while some run better with a richer mix and more timing. And then there is the oddball every now and then that can run 11.5:1 and 20* timing. A lot of it depends on the type and quality of the fuel you use.

The general rule is to run as lean as you can with as much timing advance as possible, until you hit MBT (max brake torque) or knock...whichever comes first...and then back off a degree or two for safety.

Hm, very nice to know thank you.
I'am running 9.6:1 - 11:1 AFR on 93 oct pump gas. w/ average of 23* timing(spikes to 28* in first gear 43% throttle) and i get about 1.6* of knock in 2nd and 3rd past 4500 rpms with 100% throttle.

Judging off what you said this doesn't sound very good. If you want to take a look.

There is a such thing as rich knock. Found this out when running in the 9 afrs in my car. Try and lean it out a bit. You might have to pull some timing but as stated every car is different.

How would i lean it out exactly? I'am really new to tuning .
