Need Chassis Dyno Service in VA or NC?

[jstur]

I want to have my well built 94 Cobra tuned on a chassis dyno by someone who knows what he is doing with the TwEECer and can get every possible HP out of my combo. And, at the same time, I want the car to run with mild manners in everyday driving. It is close with the stock EEC with the TwEECer turned off.

If someone could recommend an excellent service near Martinsville, VA, I'd be happy to look into this. Martinsville is located near the Virginia & North Carolina border, but I'd be willing to travel as far as upper VA or lower NC in order to access an excellent tuner. I'm tired of talking to guys who admit they know little about TwEECer, but they're willing to experiment with and learn on my car. Plus the price they quote betrays their inexperience and their need to spend all day attempting to accomplish what an experienced TwEECer tuner could do in an hour.

I was going to have Power Adder Solutions in Raleigh, NC, perform the dyno tune, but they have discontinued their dyno service for the time being.


Thank you for any help you can provide.

If you were willing to go to Georgia then Eric Brooks, of Brooksspeed is one of the best out there.http://www.brooksspeed.com/index.php Very nice guy. very knowledgeable about any mode/method of tuning

Thanks for the info. Both NY and GA are too far to have to drive this beast. I don't have a trailer to haul it.

Actually, I bought my TwEECer RT from Chris at Power Adder Solutions. Plus, he provided a 'Base Tune' to get me up and running until I could go to his shop for the dyno tune. However, since my mechanic took his sweet time about finishing the work on the car, from June 2009 until January 2010, I wasn't able to get to Chris soon enough. I bought the TwEECer from Chris in July 2009. Now, unfortunately, Chris has discontinued performing dyno tunes for the TwEECer. He still does them for SCT, but all other systems have been dropped from his services. That happened on January 1, 2010. My mechanic finally got the car back to me on January 16, 2010. And he knew he screwed me out of a dyno tune, because of things he said when I picked up the car from his shop. I didn't know until the next Monday, when I called Chris to arrange a time for the dyno tune and was told I was too late.

I've called several other chassis dyno shops around the area, mostly near Charlotte, NC, where NASCAR teams are located. Some have gone out of business. However, none are familiar with the TwEECer. However, they would be happy to charge me some big bucks, so that they could learn how to do it off my car. One guy wanted me to dump Caledit & Calcon and wanted ME to buy the software he preferred. DUH! Plus, he was going to charge me $750 for one calibration. I don't think so, when I see others advertising the service for $350 to $375! I think he was desperate for money and thought he'd found himself a sucker. He wanted to make his mortgage payment off me. Good luck to him!

Why did he stop doing tunes thru other systems ?

you can try Excessive Motorsports in Manassas, VA... http://excmotorsport.com/ It's a new webpage and doesn't have much on there. I know they are very good with foxbody's and seem to get a lot of bussiness from the newer stangs. I know they deal with SCT not sure about Tweecer.

What kind of modifications have you done to the car?

Maybe there is a reason no one uses TwEECer.

If you don't want to pay for the tune you're probably stuck if you insist on TwEECer.

Why can't you do it yourself with the dyno folks if you know TwEECer? The tuner should be able to tell you what needs to be done.

[POPSRACING]

I have offered to assist with a paid tune and support as I have worked with the tweecer since '01 and been tuning for quick a bit longer. I believe the catch is he wants to find a local dealer that's familiar with Caledit or B.E., as another option it can be arranged that I write the baseline tune and walk a dyno operator or yourself through the tuning process.

The reason most guys don't use the TwEECer is the same reason most don't use the Moates hardware either...... SCT, Diablo, and Sniper all have a click click tune setup that works half assed for even those with limited or no knowledge of what they are doing and it take all of 2min to write a tune from scratch.

I can't count the number of cars that I've had come in that were complete "value file" tunes that the customer paid "custom" tune prices..... it all became very obvious about 2yrs ago when the OBD-II testing changed and all of the "value file" tunes wouldn't pass emissions.

Amen to that!

What happened that they wouldn't pass emissions? Was it something technical the emission computers were looking for in the EEC or were the engines simply failing sniff tests?

They disable readiness monitors, rear o2s, catalyt temp switches, and lots other stuff.

[cgrey8]

I've often thought it would be nice if the code could be hacked to actually disable all those things in function, but report that all was active and working just fine to any OBD-II device that asks about them.

[cougarnut281]

You can in a way.

[POPSRACING]

In EEC V scalars can be set where its not an iisue, however the newer power pc processors had it hardcoded when certain items are disabled the pcm is in limp mode and wil never run the readiness montiotor process.....I've tuned a bunch of supercharged long tube s197 mustangs with full emissions on and passed inspections without issue.b In truth mmissiomns generally never need to be disabled.

No need to disable them when you can change the threshold for pass/fail..... :)

I even had a Turbo Cobra pass that had NOTHING other than a turbo lol....no mufflers, cats, EGR, AIR pump ect ect.

[cgrey8]

Nice. So it's just that easy to change the pass/fail thresholds to basically the max possible range and voila! You pass.

How does the emissions test know whether the tune has, for example, EGR disabled because it has been tuned to be disabled vs the EGR disabled because the vehicle didn't have EGR from the factory? For example, my 89 Ranger originally had a 2.9L V6 with the EGR port blocked off from the factory. However for 89 Rangers sold in California (and a few other places), the EGR was present. It wasn't OBD-II obviously, but I ASSUME things like that continued to happen in OBD-II era vehicles. I'm just curious as to what it is the emissions computer would pick up on that tells it that something in wrongfully disabled vs factory disabled?

And just out of curiosity, what are the parameters for secondary HEGOs? And what is it the EEC is looking for from them? Is it being over or under a certain voltage for X amount of time? I suspect things like secondary HEGOs are required on all vehicles as of OBD-II so any disabling can be considered an emissions fail. But things like thermactor and EGR are still vehicle specific and not always required, even from the factory to pass.

try these guys, they did mine when I was out there.
