JWT/ECU & MEVI combo finally earns it's keep......14.19 @ 98.54mph
 

It's about time I got some good results at the track. I am really amazed how well I ran. I left this morning gunning for 14.4's and came home with a 14.19 and a huge smile on my face. My previous best was a 14.60 @96 and the only thing different this time was a gallon of 104 octane race gas added to about 3 gallons of 93 octane.

The best part is that I also ran a 14.34 on my heavy a$$ 17's and had one run with a 99.06 trap :)

Mods: Intake, Y-pipe, VI, JWT/ECU(7200), findanza flywheel.
set up: removed passanger seat, spare and jack. 11.5lb 15" millenia wheels @ 25psi.
Weather: Mid 30's, sunny, 5mph wind, 50% humidity.

Track was a ghost yard. Only 33 cars running and no wait what so ever. I ran 30 times and could have ran 30 more.

Slip
60' 2.149
330 5.989
1/8 9.149
mph 77.22
1000 11.890
1/4 14.190
mph 98.54

I know this is much faster than my previous times, but I ran 14.2's and 14.3's all day with consistant 98mph traps so it was no fluke run. I don't know if it was the race gas or the weather. Probably a combination of the two but I have ran in cold weather before without these results. If anybody is skeptical I would be happy to scan the slip(s).

congrats

That's an awesome 60'

Change your sig smart guy.

You are almost as fast as me :goofy:

Congrats on the time

Not for long :grinno:

That's awsome. Beating your old 60ft by almost a full tenth and your 1/4 by over 4 tenths! I bet you gave a big yell when you got your slip from the post.Did you run those light a$$ mellinia wheels before and what tires were you scootin' down the track on?

way to rep I30's man...nice 60' too. i was always wondering why you car wasn't running faster. congrats!

Good time Mike!!! How long is Byron open until?

Wow! Fast I30! Mike, you ever change your KS? Maybe the race gas keep the ks from kicking back the timing?

Very nice! :D :woot:

Thanks guys.

I finally figured out a way to consistantly pull sub 2.2 60's. Before today I could not break the 2.2 barrier for the life of me. The low rpm launch is what is working, 1200 to 1300 rpms at the most. I had a slew of 2.20's, a pair of 2.19's a few 2.17's and the best was the 2.14.


Jeff, did not change my knock sensor but I think my JWT ECU likes the race gas. I was probably around 96 or 97 octane. The biggest difference today was my driving, but that was not enough to cut my times by 4 tenths and the only other thing different was the gas.
I bet Dave B will have something to say about the race gas when he sees this thread.

Cullen, I am not going to lie, I did a little dance :wall:
I have ran with those millenia wheels a few times and just have some all season Firestone's on there. Now I may invest in some slicks or get Neal to let me use his next time we go to the track.

Hell yea! good job!....I'm sure that Limited Slip that us I30's have has to help you out a litlte bit.

LSD doesn't do jack for track racing...

good job....plus the weather today was very cool....how cool was the weather when you ran a 14.6

I think they have one more weekend left

Its the Summit switch thats doing it for you. :)

Very nice times! I may try some race gas next time I go to the track. I get a 0304 after every run.

I am no expert on advanced timing and octane levels. I was under the assumption that the JWT ECU was a farily miled upgrade and did not require anything more than 93 pump gas, but how else did I pull over 2mph gain out of my a$$??? It would be nice to see some other JWT ECU owners try some race gas at the track. Now to find out how to run with 97 octane everyday.

So your traction wouldn't be ANY better than if you have an open diff? I always figured that it would help on launching....not a lot, but a little bit.

That is a awesome time....I might have to try the race gas, the next time I go to the track.

I ended up using the 3200 setting instead of the 3400 to get my best traps. So how sensitive is that fine tune control knob. I had no idea is was there unitl you told me. Have you messed with it enough to know how much of a turn it takes to go down 100 rpm's?

So glad you finally had a great day. :thumbsup:

You were pretty bummed that one weekend (so was I). I think the temp did have a bit to do with it. Mid 70's then compared to 31-36 deg yesterday. That's about +8hp. I'm amazed you could hook up as cold as that.

Looks like the 5mph wind was behind you. The better launches helped .1-.2sec prob. And the gas maybe another .1sec.

Consistant runs all year+lots of practice launches+never giving up = hella great showing!

way to go mike!

awesome :thumbsup:...I wish the millenia wheels would fit my car:(. Wow you car has great top end :)

congrats!

So any winter projects for your car?

MEVI baby....I miss my maxi :(

Too bad you or any other chicago land members were not there. I decided to go at the last minute. Byron is wierd, sometimes it's so busy it's not worth driving out there and sometimes it's like it was yesterday. I never had to wait more than 2 or 3 minutes to run. It really helped me get my lauch down.

Blu, your car would rape me from a stand still, but I think I could hang with you from a 40mph roll. :)

Josh, My goal was just to have a low to mid 14 sec car but now that I am so close to a 13 sec run I can't stop now. I may just take the easy way out and run slicks to get into the 13's because I don't think adding a cat-back or UDP or any other bolt on will get me there. If I am not going to use slicks I need another 10 hp to get close to 13's on street tires. I am thinking about the cattman headers and cat-back, but I still need to see some more dyno's first.

Race gas :ben:

Congrats Mike. I've always run my best with a mix of race gas (~96-97 octane). I've run all my 14.4s with race gas. I'm about .2 and 2mph slower without race gas. Once I stopped using race gas, I've been stuck in the 14.6s. I think the combination of the ECU and all the extra air we get really pushes the limit of detonation and the boost in octane seems to help things....at least for you and me.

I'll try your launch out this coming weekend.


Dave

The only difference between your 14.45 run and my 14.19 is the launch. The way I previously lauched was pretty much droping the clutch at 2k-2.2K then fighting wheel hop and spinning tires untill I could hook up. It was always a really ugly sight to see and always gave me 2.25 or so 60'. This time out I was getting such bad wheel hop I though I was going to break something, so I tired just scooting off the line real easy for the first few feet. Then once I had a little momentum I went about 90% throttle and if my tires were holding I laid into it all the way. I just look at it this way, it's much easier to control wheel spin from a 4-5 mph roll then it is taking off from a stand still.

Hmmm something else I can try next trip to the track. Thanks for that info :D

Give it a shot. The only reason I considered using race gas was because I had a hunch that the JWT ECU may advance the timing to verge of detonation and figured maybe the race gas could take advantage of the timing.


Dave

That's what I used to think too but after DAVE B, mike and some other people told me that they only help maximas in cornering and stuff. Maximas usually leave 2 tire marks when peeling out with an open and closed diff. so that's why I think it doesn't do much...

Your right, I doubt it does much for me at the track. Guys with open differentials have pulled the same 60' as me. I do like it in bad weather and for cornering, but I still don't think the stock VSLD is anything amazing but I can feel it work sometimes.

Good job man.. :thumbsup: ...you finally got what you wanted...hmm next year 13s?...Gotta get Neal now huh.

I wish I had tried race gas this year in my car. I almost got some once but they had closed the pumps like 20 minutes before. Next year I will probably be running race gas every time I hit the track!

I didnt mess w/mine but its set all the way down I believe. I am set of 5400 and opens at around 5100. :)

I'm happy for you man! Now I need to get my stuff back on.

Mike,
So you think the race gas made the difference? Do you know the octane rating, Im guessing 100. I have always been under the impression that race gas at the track was a waste of money in N/A cars. The only cars that really seemed to have benefitted were old big blocks or forced induction vehicles. I would like to see a dyno comparison, would be interesting.

So what is it, does the JWT program advance the timing too much, or does it cause the car to run lean up top with the MEVI?? Either way something's not right if someone can run .2 seconds faster in the 1/4 mile on race gas...

Not necessarily true. As far as the MEVI running the car too lean up top. I guarantee that's not it. Our maf can deal with the airflow of 300hp without a problem.

I do not believe JWTs programming is aggressive enough to advance timing to the point of knock on a car that is running right. JWTs program is designed to work with the 91 octane crap they get out in california.

Try this theory on for size. Mikes knock sensor could have been a bit messed up. Because his knocksensor was hypersensitive it was pulling timing a bit thus losing power. However on a car with a knocksensor that was in normal working order, there would have been no retard in timing, thus mike by putting race gas in the car made it so his messed up knock sensor was acting as a WORKING knock sensor should, and did not pull any timing. Thus he was making the power he should have been making all along.
