Did some high speed runs and found that the vehicle speed was clipped at 127. The line just stayed flat at 127. I went to 6000 rpm in 4th (auto) with 3.73 gears that should be north of 165. I checked the lower speeds with 1.55 as second 25.7 tire (245/45/17) 3.73 dif and it comes out close. but when I hit 127 that is as high as the trace will go. I have the x cal 2 using livelink 6.5.
any ideas

:D That clip has been there a while. I saw that on the dyno last year. I hit 127.5 limit @ 5640rpm and it just stayed there as I went over 6700rpm. I haven't checked out Livelink Gen II as far as that though. Hmmmm....

Just found out that the OSS input max is 5 volts, which is 127.5mph. From what I'm reading, OD automatically comes on at that speed too, but, there's some way to fix that in the tune.

I use the Delta commander, to make the shift higher than the 127 change the WOT shift RPM to what ever you want.

I sent an email to the tech dept of SCT,they said that 127 was about right for 4th gear. I replied it is an auto and sent screen shots of the log, have not heard back.

cool thing with the Delta is you can read the sct tune, save it, then make your own to suit your needs.

I was in third on the dyno when I blew through 127.5. Always third on the dyno for a 1:1 ratio. Is your trans upgraded at all? Noticed you said 4th.

a little on the up grades. Turrners here in Ocala did the work, so far no issues. In the 1/4 mile I'm in 3rd, only when I get a chance to let it roll do I go into 4th. Right now I'm right at 15X in the mile going by the odometer and the gps. @ 1.6M I'm 16X. It would be nice if the speed log was correct then I could get a better fix on the speed just by lifting the go pedal and mark it on the log. The convertor is by FTI great people

I'm about 90 min from SCT soo I went down there to see if I could get some answers.. I met with a SCT tech, Jesse, he said that the output to the data port from the ECU on the Mach only goes to 127. My thought is ford limited the auto to 130 so why do they need the test port to go any higher. Anyway it is what it is

I like that! Since there is little support for my Xcall II this may be the way to go!
