question about HPtuners 2bar stuff...
question about HPtuners 2bar stuff... i already did a search, i just had a question i cant seem to find the answer to.
in a stock LS1 setup, theres a injector size lookup table that uses the manifold pressure to find the "current injector size".
in the Hptuners 2bar setup, does this table extend out to include positive manifold pressure?
also, from the guys using it, how do you like it compared to the other options out there? for some reason, the guys using it dont seem to post about it much... im looking to put it on a turboed street car.. and id like to keep daily driver reliability/driveability. any hidden snafus?

see, the fuel system in this car will support more hp then the rest of the motor will hold... only problem is its referenced by the atmosphere at the back of the car.
if i want to run a standard vac ref regulator up front, id have to run a return line way back up there.. no big deal, but redoing the fuel lines, adding a regulator, and misc parts underhood gives a cluttered effect.. i know mixing "show" and race together is always a compromise, but i was really hoping to just toss some 60lb injectors in, and have more then enough room to grow, even with the injectors shrinking from the pressure..
ah well, im sure i can still make it look neat.
thanks for letting me know. there isnt alot of info on whats different between the 2bar and stock online.....
if anyone knows of any good threads, please link me.

we didn't extend it because a) no one has flow numbers for positive pressure and b) most people either change the fuel pressure or run a vac reg.
Also, most people get confused enough with Power enrich, Boost enrich, Openloop EQ and VE table without adding an extra bunch of zero's into the fueling equation
I know its not how it's meant to be used but the side effects are minimal.
The basic additions for 2bar over the stock OS are:
- 2bar VE table
- lose secondary VE table (if applicable)
- additional boost enrichment table
- boost enrich/closed loop enable/disable thresholds
- dual spark table function enabled
We also just changed the single vehicle price to $199 where you get 2bar & 3bar for that.

so is what he said true? can i just compensate for the "pressure drop" under boost by adding VE (and thereby adding fuel.....) or is there a downside to it?
im not exactly positive if modifying the VE in the upper end of the table(boost area) has a effect on anything related....
