After having gears, speedcal and alum. driveshaft installed, I noticed when I activate the cruise it is kinda of herky jerky like it is cutting in and out. It will maintain speed but you can feel it cutting in and out. Anyone elese experiencing this with or with out speedcal installed? Could it be realated to the speedcal installation? If anyone can help it would be much apprecaited. I just don't know weather or not to take it to the dealership or the shop that installed the speedcal.

I had a similar problem with another car. turns out one of the magnets came off the driveshaft.
Don't know if they still use magnets or not, though.

Also could be a loose wire somewhere.

Speedcal turned out to be the problem. The shop I had install it said they see this a lot and try to encourage people to go with a custom chip. He talked me into it, so I am going with a Diablo chip. Nice thing about it is that I plan on more mods such as an SC so the chip will come in handy.

I got the Diablo chip installed also, it is real nice. I don't know if it is just the shop that installed mine, but they said after I pay to have it re-burned(ticks, as they called them) the first time, there is no charge for further ticks. :smile: I like that part!! :grin:

Mine could be herky jerky now and I wouldn't know it. I've never used the cruise control. I guess I need to try it out and see if it works. It's kinda like the rear window defroster. I won't ever use that either.

I have used my cruise twice and my rear window defroster once.. Forget to take note if the defroster worked :-B When I move back to The Netherlands that may become a little more important.. the defroster.. not the cruise. :-B

Hey MOLJAY,

Thanks for the reassurance on the Diablo chip. I am looking forward to driving and seeing how she runs. The speed shop doing the burn said the two Bullitts he has installed them on responded real well to the custom burn. He said that the Ford tune is way to conservative and does not take full advantage of the new intake and better flowing exhaust.

Oh, one other thing about the Dallas Mustang Speedcal. It does not install the same way it does on a 2000 GT. The shop that did the install had to call Dallas Mustang and find out how to properly install it. The directions with the speedcal does not have instructions for 2001 stangs. Apparently the harness off of the trans is different.

OKCBULLITT: Let me know how the diablo chip works out for you. I wouldnt mind getting a custom burnt chip for mine if i knew that there would be actual gains from it.

I have 4:10's and a custom JMS chip. Raised shift points, increased line pressure, corrected speedo/odo, bumped timing,etc. I did have a problem with the torque convertor locking/unlocking while cruising but it has since been worked out. Re-burns are free too.
