Road racing day in Calgary and UTEC Impressions(long)

Wombat North · 10-16-2002, 12:03 AM

First, Thanks for a great day,40 cars, 7 subies, 3 were WRX's.
Special thanks to
HOK 2.2 RS(very fast when it runs) Sat in my passenger seat for some Data logging. Had MAF go on him just when he got to the track.
ScoobieSnaX WRX Wagon UTEC stage 4 (very nice looking wagon)
Justin RS who organised the day
Great guys

The track is approx 2 mile road course with drag strip as the main straight.

Now onto the UTEC's performance

My cars mods are
Turboxs UTEC
STI injectors
Supra fuel pump
HKS EZ boost controller
VF34
Samco hoses
Knife edged intercooler elbows
Knife edged throttle body
Gasket matched exhaust manifolds
Uppipe with ceramic coating and wrapped
Ported and polished inlet,ceramic coated and wrapped Turboxs Uppipe
Turboxs midpipe
Prodrive muffler
Underdrive pulleys
Whiteline handling pack
Stock wheels with Toyo T1-s
Axxis Ultimate pads

Temperature during the day was between 36f to 50f(perfect for turbos)
Altitude here in Calgary is 3600ft
MAP pressure without engine running was -2.2psi
The UTEC was tuned for 92 octane by me with the wonderful help of Nathan over the phone during the week. NO WB was used.
I mixed toluene into the fuel to get 95octane.
As this was a very hard test I elected to stay with the 92octane map using 95octane.

UTEC parameters were left as sent from Turboxs
TPS was still at 60% although Nathan suggested I move down to TPS 40%
Timing was controlled from 40% load and up.

Driving
No knock was detected over 3 very hard 8 -10 lap sessions except when hitting the rev limiter a few times where the ecu cut fuel causing a momentery
knock. I hit 7200rpms a few times and twice hit 7400 as my logs recorded.
The transistion from ECU timing and UTEC is absolutely seamless.
Maximum EGT's between 1525f and 1550f.
I pulled out a bit of timing in the 3500rpm to 4200rpm so torque was not so violent and was still getting wheel spin in 3rd gear coming out of corners.
The cars a rocket at 20psi(which is 18psi for you sea level guys).

Racing Results IMHO
ScoobieSnaX put on a really good show. RSX-s boys(now little boys) Blew everything etc away, I believe he had a good run with a Supra TT but I was
working on HOK's car at the time. He and I were in different groups based on track knowledge where I had been at this track before so we didn't get to
run together.

HOK didn't run because of MAF problem, but would have been very fast.

Justin RS is fast for an NA and real quick in the turns.He was staying with some of the RSX guys.It was also fun going 3 subies abreast down the main
straight with him.

I ran alot faster than a new 350Z although he was automatic(good brakes though)
AMG SLK32 (349hp) was beaten over 5 laps and I was pulling about 80yds on him down the main straight hitting 210KPH(131MPH). He was braking very late
but couldn't keep with me down the straights.
Track setup M3 lighten with race tires was quick down the straight but funny not in the corners.
I firmly believe that the stock wheels with the lighter Toyo T1-S tires gave me a big advantage down the straights but sucked in the turns, althought I was
able to keep my distance from any other car behind through the bends(just). Brakes I'll just say need major work.
The transmission is in perfect condition and I for one don't think it is glass.

UTEC SCORE CARD
I can not believe how fabulous this thing is. It starts when cold/hot/air conditioning. It pulls timing before the Knock Link is even on the second green. It
can be tuned by me who is very very limited in engine tuning. The cars a rocket as out dragging a AMG SLK32 shows.
YAHOOOOOOOOOO!!!!!!!!!!!
If you guys like other ECU's so be it, but the knock correction on the UTEC is unbelievable and hard to pass up.IMHO

Maybe ScoobieSnaX will post to explain the day even more. I still have hearing problems from his exhaust.

We both burnt our rear bumpers(he runs something on the lines of HKS)his pretty bad, mine you have to look under to see. Be aware that continued
high speed driving did this and does not happen when driving normally.

Lastly, For sale =slighty used Knock Link .

did you only run half day? i didn't see you there in the afternoon. for some reason the track got really slick and i lost the back end once. lucky i didn't wreck or hit anything.

Wombat North · 10-16-2002, 12:32 AM

Yes I left at lunch as did ScoobieSnaX. Around 1:30pm. We used the day as a tune session and as you can see my car is now tuned good enough for me.
There was some really crazy inexperienced people in some of the other groups(IN THE MORNING) with a few banging there cars on various things around the track.
Thought it was better to stop while still in one piece as I have deposit on STI already.

ScoobieSnaX · 10-16-2002, 01:11 PM

Ya, what a day! First time racing the car on that track and WOW....lots o' fun

My rear bumper is melted pretty good. I have to get the muffler shop to lenghten my Blitz custom Turbo-back a bit so the pipe actually vents a hair past the plastic

As for the UTEC, I was using a map sent by Phil recently which replaced my original stage4 map. I was using pump gas (92 octane) with a map that had +26 degrees of timing in the upper range. I was getting detonation randomly at 5400rpm, 5900rpm, and the odd time at 6200rpm. Adding fuel didn't do much by lap 3 or 4.

Once the car started to really heat up the detonation became more noticeable. I have datalogs showing the UTEC pulling 16 degrees of timing out at one point! After taking out 1 degree in the top end and around 5500 things went quite smoothly...

On/Off throttle and part throttle response is pretty good. I can sure tell when the UTEC kicks in though. It sort of feels like V-TEC in a Honda

. This must be due to differences in the ECU's timing/fuel compared to the values I'm transitioning to provided by the UTEC. I think with a little tweaking I could get it a bit smoother. I want to stress that the transition from ECU to UTEC was'nt a bad thing. I knew where it was and could deal with it easily...

Now I just need to get my hands on some Toluene!!!

inpreza kid · 10-16-2002, 06:06 PM

melted bumper too? lol. mine is melted pretty bad. i had to dremel the bumper off the muffler. it looks so ghetto now

skywalker · 10-17-2002, 01:56 AM

I played around with the UTEC this past weekend and think this is a much better unit then the unichip. The one MAJOR drawback I have noticed is that it still piggy backs off the stock base fuel MAP and adjusts it. So as the OEM ECU adjusts the fuel delivery overtime the UTEC will constantly need to be adjusted for those changes.

HOK · 10-17-2002, 04:07 PM

you didn't by chance use the Utec on the RS? hehe

Yea stupid MAF... three years and not one blown MAF... and first Lap on the track POW! at least i got a ride in Wombats Car... your crazy man... i was sitting on the passenger door in the hairpins... my ass still hurts...

Wombat North · 10-17-2002, 08:35 PM

HOK
You got in a car with me!!! and you say "I'm crazy".

BTW
I'll pad the door handles next time.

CRXguy · 10-18-2002, 01:26 AM

Damn, I wanted to come out and watch. I'll be at all track events next year. Hope to see you guys out as well.
