whats are the biggest size injectors that i would be able to run with the utec? b/c i dont really want to buy a aem now.

 

Im running 880's right now with no problem.

780's here not a problem. I think I have them scaled to a 720.

 

I called Turboxs direct and they told me that it is capable of handling 1000cc injectors.

 

Yeah the scaling features aren't a direct corelation to the max you can do, it just gives you a starting point that you can go from.. Generally 880's are the largest most would recommend realistically anyway (1000's are really overkill for most cars anyway) but you can actually run as high as 1000's

 

I dont really know how the UTEC coompensates for dead time of the injectors so once you go much bigger than 750's it probably may start acting strange for very detailed tuning. Im not sure how it decides the dead time though, perhaps it has its own algorithm? I would doubt it which is the reason they say the most is 1000cc. If you actually look at the dead time from 1000cc injectors compared to say 750cc you would be amazed and it would make more sense of what I am talking about. With 880cc you should be fine though for just about anything you want. I am running 780cc (750cc) at around 38 base (Which is too low) and at around 28-29psi I get up to 98% injector duty cycle on a GT35R. I would assume you can overrun the injectors also as well as raising the base pressure. I will probably raise my base to 50psi and never have any problems for a while.

 

thanx guys, i guess i wont have to get the aem
