Hello guys,
We are very newbies in tuning with HP tuners from France ! we are having several issues with our engine. First of all, this engine is from a 2007 GMC yukon denali 6.2L V8. We are not swapping it yet, we are trying to start the engine on a pallet.
Here's our problems :
- First of all, our scanner is displaying the speed at 255km/h while the engine doesn't even start. how to fix it if possible ?
- Our injectors are not piloted and don't fire up
- Finnaly, we put a new fuel pump large debit of 8 bar. (~116psi) is it too much ? Can it be a reason why it doenst work ?
Concening the ecu, i just removbed the vats and thats all, i'm not that much familiar with the software yet...
If some of you have some advice or ideas, i'll take it !
Thanks !
