Can't change the numbers on the blm tps voltage .42 I click on box I punch in numbers they turn red beeps goes back to 128 key on eng off

Not aware that you can change tps voltage other than to adjust it by rotating it as per the instructions under throttlepositi on sensor adjustment here  http://www.vortexbuicks-etc.com/basics.htm

It might help if you were to tell us what chip is in the car and what you are trying to do

Tt 5.7 chip trying to add more timing and fuel it says u need to use the bottom numbers on the blm wot boxes I can change them but they don't stay they go back to 128 how do I make the changes stay

[Steve Wood]

are you changing them by pumping the gas pedal and then turning the key off for three seconds after you change one before turning it on again to do the next one as the instructions tell you?  IF that does not work, try waiting about ten seconds....thi nk I saw Eric tell someone to try that

[Steve Wood]

BTW, you do know that the stock fuel pump will not support reliably more boost than stock and if you crank the boost up, you need a bigger fuel pump and a hot wire to power it. 

I cannot recall if you said the car had been modded for such things, or not

you have to use the latest version 1.4.0 of powerlogger

Iam using the plc to change the numbers I just got it from tt do I still need to upgrade? I do have an external fuel pump that came on the car don't know what it is but
It will put out about 50 psi old school tech can't do much as Iam at the track so I need to make do with what I got 108 octane race fuel 20lbs boost two limiter 26 inch mickeys no cat conv chip says 20 degrees 1-2 18 3-4  three passes tomorrow bummer if I can't change perameters

update to the 1.4.0 plc from the fullthrottlete ch.com website

 and you can still program  using the throttle pedal procedure as described in the 5.7 instructions
using plc and laptop or just viewing with a scanmaster

key on,
press pedal to floor three times and hold on third,
look at lv8  and when lv8  is in mode you want to change  lift pedal
depress pedal (per instructs) to make change to that blm cell
turn key off
repeat for any other cells you want to change 

dont know what pump you have but  a pump that can only push to 50psi will only be good to base fuel pressure + boost pressure , so if base pressure is 43psi (idleing with vac line off) then running more than 17psi boost would begin to start leaning out and would require addition fuel (inj duty)   more important would be what volume can the pump move as the intank 340 can exceed 70psi and at that pressure provide fuel for 600hp (55 gal/hr )

if logs show you arent going lean than it should be safe to work the boost up gradually and see
