the duty cycle given by the utec (others too) depends on the information that is supplied to it. meaning, it can depend on where or how the injector signal is originally cut, it will figure duty cycle on the info you give it, so if you make it think you have smaller injectors in order to make the inj. cut, it will give you duty cycle based on smaller injectors.

 

I will try to answer all your questions .....

When talking about corrected or uncorrected numbers on a dyno.... Corrected means adjusted for temperature and altitude. ISA (International Standard Atmosphere) is a sea level pressure of 29.92 inches of mercury @ 59 degrees farenheit or 15 celsius.

My temp was 63F, and about 400' above sea level. Close to the standard 59F and sea level pressure of 29.92. I'm not sure of the atmospheric pressure when the run was made. But I sense little correction will be required, and that this number is close to ISA (International Standard Atmosphere).

My wastegate is a Turbosmart 48mm and the spring pressure is 7 PSI.

I drove all the way up to Maryland to get it tuned. 920 miles. 13 hours of driving.

Numbers before the tune were not available since I had my Pro-1 exhaust installed without a dyno, and my car was overboosting to approx 12.5 psi due to the poorly designed TN wastegate mounting.

I Understand... could you please post your baseline???? I want to compare and contrast with mine and maybe help you out even more!!!!

 

No baseline available. Sorry.

Do you have the corrected numbers by any chance? If you have the file just open it with dynoviewer and change the correction to SAE...

 

One thing you should be happy about it there is no noticable spikes before full boost like most others. Was there a load on the dyno? Why didnt you try Japtrix in FL?

 

dynojets are not load based

 

The Utec reads IPW right off the injector drivers.

 

Yes...peking is making 401/418 at 9 PSI on the EU, D35010 is making 450/450 with the Utec at 9 PSI, Jetpilot is making 385/381 at 7 psi with the Utec, etc, etc

 

Yes thats possible with additional mods like larger injectors so you dont run the 380's near the limit, a return style fuel system, and 9-9.5psi. Remember he turned the boost down, and is still putting out better numbers than most stock kits and exhausts running 2psi higher....

 

I made 395 on a dynapack at *approx* 9 PSI with the Emanage and a return fuel system. There's certainly more room, but this seems safe for me on a stock block.

 

402 actually And like at 9.5 psi


Honestly I when I head back to NC to Sharif and Eric (CPR)... I will lower the boost and do the same as you if not lower... Cause honestly, going WOT and having the rear end come out all crazy like isn't as much fun as it used to be LOL.

So basically 380 WHP and I will be a happy boy.

 

Yikes that Duty cycle is scary. Cant wait for my UTEC to ship

 

edhaNothing a set of 440's or 550's can't cure.

 

The injectors will max out at different power levels, based on the differential fuel pressure seen. And without a return fuel system, fuel pressure is going to be an unknown variable between the various cars. Ignition timing also plays a big role in power ouptut, and the AF Ratio that the tuner targets. This is why you can see a large spread between power numbers, at a given Duty cycle.
