Here is the next problem, again i am unsure if the actuator works as this is a used turbo I will hook it up to cummins and set it up for install tomorrow pm. Anywho, I added pot's to mimick boost and drive but am unable to get the turbo to respond. Along with the turbo does not cycle at start up. Is ther a way to monitor and see if the shield is ouputing data?

That was the ticket had to set the screen to 0x20. Works great. just need to get another 2 pots for the drive and boost and see if there is life in this turbo. Thank you very much for the help.

I am bench testing it first on the floor then the garage to chilly so it went inside to try and figure out what i did wrong. I have the exhaust housing off for verification and mock up on the truck. It is a dfrobot lc2/ twi 4x20 lcd or so the paperwork says. I have tried hooking the scl to pin analog5 and to the scl pin, also the sda to pin analog4 and sda pin on the board, vcc to 5 volt and gnd to ground. I have tried changing the contrast it changes the intensity of the white squares. Thank You

Hello, I have been following this build and the amount of knowledge is amazing! I am trying to get a 351 turbo onto my 4bt dakota and if all goes well onto my 05 ram. i am very limited in knowledge of programming but am a mechanic by trade. I have all the parts listed in Holset HE351 VE VGT standalone Turbo Arduino Controller Tuner article. I have all the libraries and downloaded and uploded HE351mainfreq 1.04. i can not get the lcd to show any thing other than 2 rows of white squares and 2 rows of blue back ground, not sure if i am uploading wrong? I have tried controlling the turbo using the push pull pot and was unable to get the turbo to move. I uploading the simple blink test from examples onto the board and that was working. I am at a loss. Thank you
