Why would my rpm that is reported be half of what it really is? I have a Corvette LS1 engine and I put in magnetic pickup. The MAP also reports a negative number. . I am having shifting problems. I'm hoping that changes when I get everything set up properly. It seems the manual mode works sometimes and sometime it don't.
Where do I get the registration key?
What is the reverse logic mode in the mode input setup? When should those blocks be checked.

Thanks
Ronnie

Ronnie,
If you are using the white wire from the factory computer for the rpm signal than you need to enter in the engine as a 4 cylinder. Please unhook the map and do not use it. The reverse logic it for if you wanted something to be on all the time and you have to activate it off instead of you having to activate it on. Feel free to call or email!

thanks

Okay, the rpm is correct now but I am having trouble with my speed. The TCU is not reporting my speed accurately. It is probably 10 to 20 percent of what it should be. I guess that is the reason it will not shift now. Not even in manual. What should my figures be in the program. I put my final ratio at 3.42 (my rear gears and left the pulse thinging at 2000. What should they be? I copied another Corvette owners tune and he had 1.00 as the final ratio and the pulse was some where over 30k. What do you think?

Ronnie,
I suggest that you start from scratch. Open up the Tcom program confirm that you have version 1.019. If you do go to file then read all tables. Open the file named "cutlass". From there go into the operational perameters and enter you rear end ratio and tire size. After that Go into wide open throttle setings and enter you Max RPM. Once this is all dont send the file to the TCU open your monitor make sure everything is reading right and test drive it.

Thanks

I checked and my version is 2.9.20 It is not 1.019. What now?? I left you a phone message with my phone number. What should the pulse per mile figure be in the setup?

Thanks

Still needing some help!
