upsetting 1/4 mile time

[GSXdsm97]

I cant break the 15s WTF, this is ass.

MODS-N1 turbo back, injen intake, 1g BOV, walberro 255, FIC 650cc, dejon MBC, DSMlink, eprom ecu, AEM wideband, B&M short shifter, eibach sport line kit, GR2 struts,

why cant i get into the low 14s or even high 13s. i should be there with these mods. my launch was at 3750, i was at 12.671 at the 1000feet. my fuel trim is at 4.9 and i gave it more air, wideband reads at 13.4 to like 14.0. anyone have any suggestions on what to do.

 

[kahl23]

If your wideband is reading 13-14 under full load you need to add fuel ASAP, thats pretty lean. On pump the suggested AFRs range from around 11.6-10.6, depending on who you ask. Also, your launch RPM seems a bit low, should be in the 5k range, what kind of 60' times are you pulling?

 

[GSXdsm97]

2.274 was my 60, what should i take my fuel to. just move the global and the deadtime up. i just put my launch at 4000 but i didnt try it, it was so busy at atco

 

[1992awdlaser]

^^I agree with everything said. Your times are where they are because of driving.

 

[blackGSX2g]

No way I'd launch that car at 5k. Are you slipping the clutch, or does it bog down? Your E.T. is greatly determined in the first 60ft, with a 2.2x you definately have some room for improvement.

 

[kawboy]

Why wouldnt you launch it at 5 blackgsx2g?

3750 sounds like a bog to me.

Lmk the next time you're goin to Atco, I'll showup

You should be able to get your 60 ft to 1.8 or so with the stock clutch. If you do that it should take around 8 tenths off your time. Post a log on dsmlink forums and then give me a link and I can look at it to tell you what to do.

 

[GSXdsm97]

yea it just bogs, that it picks up.
R-T=.337
60=2.274
1/8=9.784
1000=12.671
1/4=15.121

you think its that slow becasue of me..... i shift at like 6200 (ha) is that too much. when i drive her on the street it pulls so hard i dont understand.

 

[blackGSX2g]

Stock clutch + T-25...wouldn't hold anything past 4k on my car.

I currently launch my car at about 4k with anti-lag (20ish psi launch leading to 31psi overall) and usually hit about a 1.8x-1.9x 60ft on some all season tires...looking at a 126-128mph trap speed

But then again maybe my stock clutch was bad.

 

[GSXdsm97]

my computer that i use sucks the battery is ass i dont know how to get a log onto my desktop from that computer

 

[kawboy]

Going to 6800 or 7 between shifts may help with bog between shifts if you're getting any lag.

4500-5500 will work good for a nice launch and no bog.

EDIT: 4500 on stock clutch

 

[SethA]

Are you still running the stock T25?

Seth

(too late : -))

 

[GSXdsm97]

yea still have the stock t-25 i want a evo 3 16g but if i cant go faster with these mods it wouldnt be worht it haha. so rev the car out all the way out for shifting

 

[kahl23]

As far as the fuel goes, do you have an intimate knowledge of Link software? Under ECU, go to Fuel, and then adjust the fuel trims at each RPM until you see the desired AFR

 

[kawboy]

Only if its got a delay between shifts. T25's don't really breathe at those high rpm's so you're not really doing it for power.

 

[GSXdsm97]

ok yea as far as the link im new to it, but i know what your talking about, as for the t-25 shifting, i should shift at like 4500 or 5000

 

[1992awdlaser]

You are shifting at a good rpm. The stock intake manifold and turbo will stop making power after that. You just need to launch better and tune it.

 

[kawboy]

Are your global and deadtime inputted correctly for the injectors?

 

[whitetsi95]

Whats the old sayings? 90% dirve 10 % vehicle.

 

[GSXdsm97]

if that was the case i should have got a mustang (joke) um yea my ecu is set correctly. i guess my tune is just cheeks. and i dont wnat to do much to it becasue i dont know what im doing

 

[GSXdsm97]

also i think my ecu isnt working correctly becasue it throughs a code for an injector circuit malfunction but they are all firing and it still pulls as hard as it did when i first got it

You have all the other goodies (afpr for the 255?). It would be a shame to waste your car on the stock turbo. It sounds like after you sort out some tuning issues you should call and order a turbo! You won't regret it.

Good luck,

Seth

 

[kawboy]

Worst comes to worst, hit me up when you're going to Atco again.

Im looking to run my car, and I wouldn't mind helping you out or taking a look for you. It's alot easier to tell you why you're slow or whats wrong after seeing the car in real life then via message board.

 

[GSXdsm97]

i dont have a AFPR it gets better gas mileage than it did with the stock injectors and pump. a turbo is on the list for the next thing eventually. and yea ill deff hit u up next time i go to atco
