The same with me, I just can't get a custom program either. Hell, I'd rather invest in educating myself about how to engineer a good ECU...ok, maybe not.......

 

Nope. I was just pointing out that a lot of Northeast tracks let you run as long as there is no snow on the ground. Here in Kansas City, they won't let us run unless it's in the 50s and sunny.

I'm moving to the DC area in a few weeks and I cant wait till October when it gets nice and cool! My times have never been to great down here in the Lousyana heat for the heavy mods I have. I should run much better at those gosh darn Yankee tracks

 

I was curious...will MEVI work with a Turbo kit?

 

Yes

 

Glad to see that you were able to get some runs in. Those are great times considering the weather conditions. Can't wait til late fall to see you better your best time. Here in Albuquerque they have finally put a bill that past 7-0 to reopen our 1/4 mile track that has been closed for about 2 years. So, hopefully when that gets reopened I can make some 1/4 mile runs and see how well I do. That is one thing I've been waiting on. Again congrats and I'm glad your enjoying the mod.

All you need to do is engineer an adapter harness, then you can run a 95-96 fed spec ECU. Those are much easier/cheaper than reverse engineering the ECU. That is unless you have years of experience in that field and the proper hardware/software to do it.

 

I WILL get a 14.4@99mph by the time the track closes this year. I can feel it And thanks again for making my dream of having a VI on my car come true. I've been wanting a VI system on my car ever since the 5th came out.

Dave

 

Thanks for the info (same to you Nismo87SE). I guess I will look into getting the taller and closer to stock 225/50R15 BFG drag radials (24" tall) vs the 23" tall 205/50R15.


Dave

 

Looksl ike that verifies my findings. In my Auto, I gained exactly .4 seconds.

IanS

 

This may have been answered already, but what's the best size for the auto? They gear ratio's are different so what would the optimum size be? I don't know where I got this (I want to say Don In Texas said it), but I have 205/45/15 in my head. That's seems awfuly low profile for a drag radial. What do you guys think? I've decided to run them on my steelies for now until I can get some lighter wheels. Gotta be better than my 17's.

 

Don ran 205/50-15. I have a set of kuhmo's in that size mounted on my stock 15 inch wheels. I haven't tested them that much, but it should help us out in 3rd, because it gets us further into the powerband before we cross the line. My speedometer is well over 100mph when I cross the line with those tires. If anything, my 60 ft times are more consistent now. I will fully test them when the weather cools down.

 

Your definitely welcome

-John

 

Yes 205/50-15s are the best tire size for the auto. This gives it a final gear ratio of 4.0 vs stock 3.64. Simulation results show a 1-2 tenth drop and 1-2mph increase in trap with a 4.0 gear vs 3.64. Also it appears that if an auto had a high stall convertor + 4.0 and cut consistant 2.0x 60'. It would run a 15.1 @ 90mph stock and around 14.8 @ 92mph with I/Y/E.

 

I'm just applying what you said and comparing it to VI numbers. And it appears the VI give approximately .3-.4 and Ian showed a .4 second increase and 3-4MPH with the VI. Then I would figure that the VI is probalby the best bang for your buck. Becuase From your calculations...you only get a .3 second gain and 2mph gain with the I/Y/E which altogether would run you around 600-1200 or so depending on what brand of I/Y/E you get. Does that seem about right using common deductions.

-John

 

Generally that is the idea. However I assumed both cars had the same 60' times when in reality the I/Y/E car would run a lower 60'. Stock vs I/Y/E there is a 4 tenth/2mph difference in the 1/4 from a 5mph roll (this takes the launch variables out). Now I/Y/E vs I/Y/E + MEVI is a 2 tenth/3mph difference. After 0-5280ft (1 mile) run the MEVI car is 127ft infront of the I/Y/E car and that car is 139ft infront of the stock car. After 1 mile the MEVI is at 130mph with a 12 car lead while the non MEVI car is at 125mph. Can you say owned.

 

That's and it's so true. It amazes me how quickly the rpms wind out from 4500-6500rpms. It's just so smooth and linear. Before the VI, I could "feel" the engine slow down as the rpms swept past 5500rpms and from there I could feel when I needed to shift. Now the VQ just rushes to the rev-limiter, which I've hit multiple times in 1st and 2nd.



Dave

 

Im really thinking about odering this next week from all the good things that are said about it, and the shear understanding that I get when people explain the point of it all.but I am kind of sceptical about getting it since I have Cold Air...I do know that CAI suffers up top, will the VI really help at this ?? Guys that have it, what did you think of it on your first test drive around ?? I know that the first time out is the best when you jump on the local highway and test it out, what did it feel like ?? alot better ?? Breath alot better ??
Notice any low end touque lost cruizin around town ??

 

But, you already know my feeling. The best thing to do to get a good response on this subject is start a new post and ask for all who own and MEVI or VIM to please read. Therefore you get a lot more of a response. It just pulls. I have a JWT-ECU and I actually pull it all the way to 7200 where it hits the Rev limiter it rocks. Before you know it your going 100 it rocks. I love this car. And this mod rocks.

-John

 

Rain conspired against my VIM on/off test. However before the rain I was able to race against another org member. He has an 95 auto with I/Y/E. I ran a 15.78 @ 91.67 mph to his 16.24 @85.97.

DISCLAIMER: Weather conditions were BAD and the track condition were beyond BAD! I had to feather the gas when I shifted to 2nd gear so i wouldn't lose traction!

Anyways we were bumper to bumper in first gear. When my max hit 5000 rpm in second gear, I started to acclerate hard and pulled ahead by a fender. Third gear was where it was apparant the VIM was working hard and I ended up a half a car length ahead as we crossed the finish line. It was almost the perfect example of race between a VIM and non-VIM equipped maxima. Unfortunately rain ruined the perfect opportunity to run against Toolrocks' 5-spd maxima.

 

Can't wait till you have a good race day were the track and weather are good. What other mods do you have on your car??? How do you like the VIM???

-John

 

Hey speedstrip, you were at the 7580 last week?? You have VI?? damn!!!!
Who were you? did you see me? I have white 98 with red/clear tails. I thought I was the only one to run 16+ with intake,ypipe. my trap was 84.

 

arghhhhh!!!!! these threads are killing me...someone slap me in the head and tell me to order the vi...i have the cash to order one in hand but after reading all this im still unsure about spending all that cash for .3 seconds ill use this thread as my final decision someone give me an honest yes or no answer on if i s hould get it..

thanks

Jon

 

.3 seconds is approximately 3 car lengths at 90mph, as I understand it.

IanS

 

I think anybody that has this would say this is a definite yes. But, then again I'm one of the people selling them. My honest opinion if I wasn't selling them would also be a yes...what else would you be looking at getting, if you didn't get the VI???

-John

 

well i can get a zex kit for 400 bucks brand new and with all the things i need..i figure it will bee a couple hundred bucks more than the vi with all the parts i need to run the nitrous...BUT! i plan on keeping my car for at least another 3 years and i dont want extra wear on the engine....i figure id keep it n/a with as many bolt ons as possible..what do you think???

 

And of course I'm selling them too, so i guess I'm biased also.

 

I have a 95 SE and was debating getting nitrous. During that time, talk of the VI began. My thinking was that my car with 130,000 would probably do better with the VI versus the shot of nitrous. I'm afraid that if I went the nitrous route, I'd have to get at least a 100 shot - if you're gonna do it, do it all the way. To do that properly would cost a good bit of money and would put a big demand on my old engine. I decided against nitrous (at least for the time being). I still don't have my VI but it is due in any time. After seeing speedtrips in person, I can't wait. I'd say get the VI while people can. You can always add nitrous later.

 

Get the VI it is an awesome mod. Personelly I would probably get this before I got my Y-pipe. But, that is just from driving around with it.

-John

 

Shameles plug John? LOL

Also. I sent you the check, again sorry for the long delay.

DL

 

Yes I was at 75-80 last friday. I have had my VI installed since late may. I'm a white guy with short brown hair I had on a blue t-shirt and light tan shorts. I have a white SE with the stock 16" wheels. There were several white maximas there that evening and I know I watched you run but I can't remember talking to you.

 

You better believe it . And thanks DL.

-John

 

...and I say GET ONE!! It's an awesome mod. I think you'll see much better improvements as we get further into the year. I was running 15.5-15.6 in this heat before the VI. Now I'm hitting 15.1-15.2 with it. When the weather cools off times are going to drop.
