Project Black Golfball-plans for 2008 Options

the timing on the stock maps is VERY agressive. You're only able to lean out your a/f so far on pump because I took out 6 degrees of timing around 4000-6000. I'm doubtfull about there being a tuning fix for this. On Marcus's stroker we tried more timing, less timing, more fuel, less fuel. It knocked all over no matter what.

I shut off closed loop and could just play with the A/F while driving. It knocked 43 counts cruising all the way from 20:1 A/F to 10:1 all on the wide band. Nothing helped.

God I hope I don't jinx myself....but
Just got back from Darryl's where we swapped in the new lifters, which was fun on a hot engine. After driving around for 20 min, the knock is totally under control. Drove the half hour home, and had a total of 8 counts of knock. So far so good!

NC did burn me a new chip to ignore knock below 3500 rpm just in case. I figure I'll keep an eye on it and probably have that removed in the next revision of the chip.

So I'm crossing my fingers until tomorrow!

Thanks again to Darryl and Nathan! It's nice to be able to DRIVE the car again!

Good job.

Had a big weekend of racing, went Friday for T&T and a little Trophy class and went back on Saturday for the Brackets.

First off the random knock is basically gone, so after all that swapping of parts it ended up being the lifters.

Friday night I ran about 7 or 8 times, I haven't cleaned the car out to finf all the timeslips. The times were unforntuantly all over the place from 12.8's to 13.7. The rich knock coming off the stutter was killing my timing at the beginning of the runs and then killing my 1/8 times. I started playing with the mid knob on the maft to lean out the fuel and it seemed to help. I did make it to the semi-finals and came in third in the Trophy class.

Saturday I decided to go back and run the Bracket class. After leaning out the fuel to help with knock coming off the stutter I ran:
12.92 @ 107.46
12.80 @106.93
12.99 @ 106.67

So I dialed a 12.9 for first round figuring it it ran good I could pedal at the top end. I ended up running a 12.88 @ 107.2 and breaking out. I ran it out because the guy was slightly a head pedaling me at the lights so I thought I ran slow. Looking at the slip the other guy got me at the tree with a .031 to my .122.... so I screwed up at the light big time. I did find out the guy I ran was a past divisional champ, so at least I got drilled by the best!

All in all not too bad for 18psi and 80's heat.

NC, is there anything we can do with the stutter/tuning setting to help make it more consitent with the amount of knock at the start? The slower runs were after >20 counts, faster when I only saw <13. Oh, I think I could use that additional timing at the top end that we talked about. I had zero knock(on race gas) once the intial first gear knock died down. Although I haven't turned the boost up to last years numbers yet (20-22psi)

Nothing really to speak about other than it's nice to be able to drive the car...been too busy fixing the DD Impala. Had a horrible whine, replaced a CV and put new brakes on it. But it looks to be trans related whitch could be big money to spend on a 01 with 140k. Friend of the wife is bring over a loaded 02 PT Cruiser with 33k Friday, could be my next car if the Impala repairs are cost prohibited. PT are kind of a chick car to me but we'll see.

Hitting the track in the Talon for the brackets Saturday for some more abuse. Need to concentrate on my reaction times.

[ncgalant]

Worst part is that the PT will get worse milage than your impalla. I've driven two of them both owned by work. They are pretty consistent at 26hiway/22city. Pretty crap that way

[black92_tsi_awd]

I forgot you drove them...any other mechanical issues? My Impala only get 22-25...but your right, I expected better.

[black92_tsi_awd]

Got a couple of trips to the track to update

6/28 Bracket #6
Got a new personal best of 12.43 @ 109.94
The rest of the runs has a terrible bog on the launch with 2.0xx 60's
12.85@109.99
13.04@109.74
First round dialed a 12.85, redlit and ran it out to a 12.69@109.22 after screwing myself staging. Thought i rolled through the beams, back up, staged again...

I tried everything to eliminate the bog and knock coming up on the stutter. Hard and soft dry hops didn't seem to matter, coming up on the stutter a couple times before staging seems to help clean up the rich knock cause by the stutter.

7/12 Bracket #7
13.00@108.44
12.97@108.11
13.245@107.13
All 3 rounds had a bad bog on launch, one accountable to alot a knock on the stutterbox pulling all the timing.
First round dialed a 13.2, planned to dump if it launched. But I redlit again and ran it out to a 12.55@107.77 with a 1.70 60'! My best to date. So that really looked good, redlighting by .05 and then running .7 under my dial...dumba$$!

I think I finally figured out the bog on launch. The last run I made an effort to purposely slip the clutch and it 1.7'd. So I'm thinking in an effort to get better lights I'm popping the clutch and bogging the motor.

Next race is 7/26. Worse part is that I've not gotten past the first round in 6 races and have less point than last year when I only ran 4 or 5.

I'd like to annouce the latest addition to the SOB Racing Team....my wife!!

She made her first passes (3) down the strip last Friday. Her third run was clean, 15.5x @ 103 with a 2.8x 60'. She was leaving normally (like a stoplight), I didn't think she was ready for the stutterbox launch! My clutch took some abuse since she hasn't run a stick in about 2 years but it was worth it to see the adreneline look in her eyes!

She was pretty pumped as was I...she now understands my addiction.

I made only four runs since I was trying to get her on the track, all in the 12's with a best of 12.54. Last run I made was a hail mary, crank the boost run. I ran out of fuel (13.5:1) and picked up some knock in third and forth....oh well. I had the MAFT WOT adjustment out at +35% but I didn't feel like adjusting the base setting to get some more fuel.

[turbohcar]

Tell your wife I'll race her next time in the girlfriend's Grand Am LOL

[awd4kicks]

Awesome Chris. Good to get the family involved more.

Was this last Friday night when all the Daxcon guys went to Cordova?

If so, how did everybody do?

[black92_tsi_awd]

You got a race Turbo...I predict low 14's for her next outing!

Yeah Kicks, we had about 12 people come out to race plus some wifes took some runs. Everything from two 9 sec cars pulling wheelies (a red Formula and Drwizrd's on CSS purple Mustang), couple crotch rockets, an early big block vette, late model Caddy, Crown Vic, Focus, family mini-van and a few others. Was a interesting pit scene... Not all cars are earth shattering, but everybody was competiting in their own speed range.

Most importantly, everyone drove home in one piece....a race occurance for our little DAXCON outing! Somebody usally breaks something.

[turbohcar]

You got a race Turbo...I predict low 14's for her next outing!

Hey, atleast you got somebody else into the sport. Mine won't even ride along down the strip, but she does really enjoy watching from the bleachers. I guess it's a start. Good job Chris

[black92_tsi_awd]

Finally some progress to report!

I now have some more agressive chips, thanks to NCgalants hard work. After a couple hours of fiddling we got the 512 chips to work in my ECU. I now have some base chips to make up for the WOT lean condition so I can turn up the boost past 20 psi. I also have a chip with increased stutterbox rpm (5800) to help launch it. And finally a Race Gas Only chip with a more agressive timing map at WOT. I put some drive time on the pump gas chip and it looks pretty good.

I also had time to look at some video of my last outing, the rear suspension is still squatting 3-4 inches so I'll try stiffening the shocks next time out to lower the 60'.

Thanks again NC for the time and driving out "to the country". Next time I'll try to have a decent beer in the house...or you can try the wife's vodka lemonade, a couple of those will get your world right!

Next outing is next Sat!

[awd4kicks]

sounds good keep us posted.

[black92_tsi_awd]

Pretty decent outing for 19 psi. Ran a 5800 stutter that seemed to help launch, alll run had a consitent 1.7x 60' NCgalant's tuning helps out again!
12.588@108.8 on the first run with the chip adding more fuel
12.56@109.09 on second run with 20-21 degrees of WOT timing
12.463@109.52 on third with some more WOT fuel on MAFT

First round, driver was an idiot and did everthing wrong...I need a new driver Figure's this is the most consitent the car has EVER been! I was going to try to buy back in to get another chance of going rounds,

I think I may have a wideband sensor going bad...first run had a 12.5:1 which is what I like. Next three run the wideband ran 13.4 even with the MAFT adjusted 7 more clicks rich at WOT. Even the drive home under accel the wideband would only read 13.4

Anybody had any experience with wideband sensor starting to die??? I read that they usally read lean when they croak but this one still ocillates around stoich going down the road. This ones got about 2 yrs of racing with leaded 110-112 in the tank. I hate to replace a $90 sensor and not have it be bad.

[ncgalant]

Seeing any knock on the runs with the extra timing? If not, I say we add some more. If we can keep running 12.5:1 and add another couple degrees of timing you may have some more in it. Overall I'd have to guess you're still around the best a 14b can do. Glad to hear she's pulling well and still holding together

[black92_tsi_awd]

I didn't get a log of the third run (12.46) The last run showed <13 off the stutter and <3 in third....but I missed that gear so it probably cause the knock hit.

I never got a chance to turn up the boost since the wideband reading were showing lean. But I'm not sure that was accurate now...

[ncgalant]

It look like you've picked up almost 1mph over your last chip. I'd be interested to see what your actual A/F is after you get the bugs worked out of the sensor. We may need to bump the 1600hz+ multiplier up another notch.

I just realized how close you are getting to my 111 I ran in the galant. Another couple of chips and a cool day and you may get there. That being said, you're probably making over 300hp at the tires. I just did the calculation. It says you are making 334hp

[black92_tsi_awd]

Ordered a new bosch Wideband sensor today, hopefully that's the problem. I did check the downpipe gasket in case it was leaking air into the exhaust....it wasn't.

334 hp sounds pretty good!
