Alright, here goes....

I recently (2-3 yrs) had my Daytona Shelby rebuilt and upgraded.

Went from a 2.2 to a 2.5, bigger turbo/intercooler, bigger injectors, forged pistons, ect.

Sent the computer (3 times!) to FWDPerformance (based in Texas) for adjustments.

My problem is that the car wont start. That is to say it starts, dies, i start it again, it dies, rinse and repeat anywhere from 2 to 12 times. Eventually it stays "alive" however it idles like crap. In talking with the person that built the engine we're pretty sure its a fuel issue (computer not providing enough fuel to the cold engine). We had sent to Texas to fix, but it keeps coming back wrong, so the computer has removable chips in it now.

Does anyone know anybody that specializes in computer fixes or maybe know of standalone EMS'? I'm currently working on this, and i have a couple of leads, but i've dealt w/ this for a couple years and its rather embarrasing at times. Plus i imagine its not a great thing for the car. This is the last peice of my puzzle, the car is mint besides this minor tweak.

Any help and/or leads are greatly appreciated!

 

Cindy has done countless cals for the 8v cars. She has it down pretty well. I cant see 3 cals, and no change. I think its somthing your overlooking. Have you clean the ais motor in the throttlebody? What about timing? HEP good?Absolutly sure there are no vac leaks? Is the car getting any codes besides the code 53 for the re-cal?
There are other options out there, but they are expensive. Very expensive. Cindys cals scream. Figure out your problem, and you will love it.

 

Alright, Engine is pushing 3 codes:

12 - Battery or Computer recently disconnected - This makes sense to me as i unplug the car every winter when i put it away to charge the battery

13 - MAP Sensor or vacuum line may not be working - Not sure what to do about this, pretty sure they're all hooked up and good to go

34 - Speed control shorted or open - Huh??!!??

Now with that being said, when I started having this issue (as soon as i replaced the stock computer, car worked fine w/ mods but stock computer, it was slower though) i went to the man who built it. He's a Dodge Mechanic/Enthusiast since before these cars came out, he also had/has a few that he built for more HP than mine and they don't seem to have this issue. He worked over the engine and didn't seem to think they were the issue. I've tried different computers to varying effects, however the same issue persists. With that being said, after 2 to 3 years the codes may be hindering my progress at this point even if it is the computer. I'm getting towards the end of my rope and short of driving the car to Cindy i'm not sure what i can do.

I don't suppose you, or anyone else w/ experience, is located in the New England area? I haven't looked at the MAP sensor or the hoses to it, as unfortunately I am not mechanically inclined. Though i have enough confidence from other work i've done that i wouldn't mess it up were i to try, i wanted to explore everything before it came to that.

I've gotten some pretty strong advice that it's the computer, but i'm interested in any opinion/work that makes this better, no matter the work or $$ involved. I've sank a pretty penny in this car, enough so that i can't write it off and get a different one (plus i absolutely love the car).

Any help/assistance would be greatly appreciated.
