I have tried -

new 01 pcm
alternate # 96 pcm
stock 98 pcm
a reflashed 99 pcm

with no success.

believe me when I say I have tried it all. very frustrating since it does make more power, but something isnt right.

todays the day to find out what Sean could do with it

hehe, do you have my dyno appointment written on your calendar? hehe

Anyway, here is the chart. The car is a lot peppier now, and they got rid of that nasty backfiring crap at 5000. Run 1 was with the program I had in the car before, not the stock program.

THANKS SEAN!

That's looking better. What was changed to prevent the crapping out at higher RPMs?

 

[Anaconda]

Just look at the difference between A/F at around 5000 and you should see. The car was leaned out, because it was running rich there.

 

[v10kingsnake]

doesn't seem to make much sense to me. of course it had to be leaned out as anyone could see from the previous a/f chart, but why and how could anyone be having trouble leaning this out unless the vec2 doesnt allow you to adjust like that, but i thought it did? seems like with all the people having problems the fix has got to be tricky. can you explain.

 

[Anaconda]

What part doesn't make sense? It needed to be leaned out, Sean leaned it out, and the car now has more power.

bro, how the hell could it be as easy as you say it is when you have several guys on this post that chimed in how they to have torn this apart, switched several computers in and out, cleaned this, replaced that... and still have this dip. and many of these guys have had the car to professional tuners! i dont have a vec2 in my car. but the way i understood it to work is you could add or subtract fuel at any rpm level. if this is correct then it should be easy for these guys to correct the dip by adjusting the program at the specific problem rpm. SO HOW DO YOU EXPECT ME TO UNDERSTAND HOW NO ONE ELSE THAT POSTED HERE WITH THE PROBLEM CAN GET IT FIXED. Any one else here want to chime in on this, Sean Roe maybe. i am a potential customer for the vec 2 but not if sean is the only guy who can program it perfectly.

 

[Anaconda]

First off, stop calling me "bro." I hate that.

I don't know what he did. But all that I know is it took like an hour, start to finish. They did five pulls (4 tuning, one baseline). As far as I can tell, all that was done was smooth the A/F level across the entire power band. You can see before that at the 5000 RPM level, the car was running ridiculously rich, and now it isn't.

I used to tune my Mustang with the TwEECer R/T, which is real time datalogging software, similar to the VEC2 in operation. That was a pain to learn, so I have no desire to learn it again for my Viper. I know I could, if I really wanted to spend the time and effort, but quite frankly, it isn't worth my time. Now I pay the pros to do it.

 

[v10kingsnake]

sorry for the bro. but your tone in the beginning towards me was semi-arrogant to say it lightly. so i tossed that upper jersey, long island bro at you. hope you didnt get all bent out of shape about it as it was truely meaningless. -v10.


but i would still enjoy hearing in from roe on the fix for this problem so many people complain about. i know sean is a top notch guy and he should be responding when he gets around to it.

 

[Anaconda]

Doesn't offend me, I just find it to be a dumb expression. By the way, I am originally from Wildwood Crest, NJ.

My whole point is that it doesn't seem all that complicated. The car is not going to backfire with a 13:1 A/F ratio. Before, the car did backfire when it was so rich that it went off the chart (below 10:1). All that was done was lean it out there, making the car not backfire, and that problem was solved.

 

[J DAWG]

Good results. No doubt the potential is there. I personally will continue to try to figure it out with the help of Sean and many others because I like the ease of operation and the range of tuning the VEC2 provides.
